QUESTION

EmbeddedKafka failing since Spring Boot 2.6.X : AccessDeniedException: ..\AppData\Local\Temp\spring.kafka*

Asked 2022-Mar-25 at 12:39

e: this has been fixed through Spring Boot 2.6.5 (see https://github.com/spring-projects/spring-boot/issues/30243)

Since upgrading to Spring Boot 2.6.X (in my case: 2.6.1), I have multiple projects that now have failing unit-tests on Windows that cannot start EmbeddedKafka, that do run with Linux

There is multiple errors, but this is the first one thrown

Reproduceable via spring Initializr + adding "Spring Kafka": https://start.spring.io/#!type=maven-project&language=java&platformVersion=2.6.1&packaging=jar&jvmVersion=11&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo&dependencies=kafka

And then have following test-class to execute:

package com.example.demo;

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.kafka.test.context.EmbeddedKafka;

@SpringBootTest
@EmbeddedKafka
class ApplicationTest {

    @Test
    void run() {
        int i = 1 + 1; // just a line of code to set a debug-point
    }
}

I do not have this error when pinning kafka.version to 2.8.1 in pom.xml's properties.

It seems like the cause is in Kafka itself, but I have a hard time figuring out if it is spring-kafka intitializing Kafka via EmbeddedKafka incorrectly or if Kafka itself is the culrit here.

Anyone has an idea? Am I missing a test-parameter to set?

Answered 2021-Dec-09 at 15:51

Known bug on the Apache Kafka side. Nothing to do from Spring perspective. See more info here: https://github.com/spring-projects/spring-kafka/discussions/2027. And here: https://issues.apache.org/jira/browse/KAFKA-13391

You need to wait until Apache Kafka 3.0.1 or don't use embedded Kafka and just rely on the Testcontainers, for example, or fully external Apache Kafka broker.

QUESTION

Springboot 2.6.0 / Spring fox 3 - Failed to start bean 'documentationPluginsBootstrapper'

Asked 2022-Mar-25 at 06:14

I'm trying to initiate a Springboot project using Open Jdk 15, Springboot 2.6.0, Springfox 3. We are working on a project that replaced Netty as the webserver and used Jetty instead because we do not need a non-blocking environment.

In the code we depend primarily on Reactor API (Flux, Mono), so we can not remove org.springframework.boot:spring-boot-starter-webflux dependencies.

I replicated the problem that we have in a new project.: https://github.com/jvacaq/spring-fox.

I figured out that these lines in our build.gradle file are the origin of the problem.

compile("org.springframework.boot:spring-boot-starter-web") {
   exclude module: "spring-boot-starter-tomcat"
}
compile("org.springframework.boot:spring-boot-starter-jetty")

Here is the build.gradle file:

plugins {
    id 'org.springframework.boot' version '2.6.0'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

repositories {
    mavenCentral()
}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web") {
        exclude module: "spring-boot-starter-tomcat"
    }
    compile("org.springframework.boot:spring-boot-starter-jetty")
    implementation 'org.springframework.boot:spring-boot-starter-webflux'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'io.projectreactor:reactor-test'
    implementation "io.springfox:springfox-boot-starter:3.0.0"
}

test {
    useJUnitPlatform()
}

I issued the command gradle clean bootrun. The result is this error:

 gradle clean bootrun

ANSWER

Answered 2022-Feb-08 at 12:36

This problem's caused by a bug in Springfox. It's making an assumption about how Spring MVC is set up that doesn't always hold true. Specifically, it's assuming that MVC's path matching will use the Ant-based path matcher and not the PathPattern-based matcher. PathPattern-based matching has been an option for some time now and is the default as of Spring Boot 2.6.

As described in Spring Boot 2.6's release notes, you can restore the configuration that Springfox assumes will be used by setting spring.mvc.pathmatch.matching-strategy to ant-path-matcher in your application.properties file. Note that this will only work if you are not using Spring Boot's Actuator. The Actuator always uses PathPattern-based parsing, irrespective of the configured matching-strategy. A change to Springfox will be required if you want to use it with the Actuator in Spring Boot 2.6 and later.

QUESTION

IntelliJ - Invalid source release: 17

Asked 2022-Mar-17 at 13:46

I've created a new Java project in IntelliJ with Gradle that uses Java 17. When running my app it has the error Cause: error: invalid source release: 17.

My Settings

I've installed openjdk-17 through IntelliJ and set it as my Project SDK.

The Project language level has been set to 17 - Sealed types, always-strict floating-point semantics.

In Modules -> Sources I've set the Language level to Project default (17 - Sealed types, always strict floating-point semantics).

In Modules -> Dependencies I've set the Module SDK to Project SDK openjdk-17.

In Settings -> Build, Execution, Deployment -> Compiler -> Java Compiler I've set the Project bytecode version to 17.

Gradle

plugins {
    id 'org.springframework.boot' version '2.5.6'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.app'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-websocket'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    implementation 'com.fasterxml.jackson.core:jackson-core:2.13.0'
    implementation 'com.fasterxml.jackson.core:jackson-databind:2.13.0'
}

test {
    useJUnitPlatform()
}

I've looked at all of the answers here but I can't seem to fix this. I must be missing something but I can't find it. I've not had any problems using Java 8 or 11.

How do I resolve this?

ANSWER

Answered 2021-Oct-24 at 14:23

The message typically entails that your JAVA_HOME environment variable points to a different Java version.

Here are the steps to follow:

Close IntelliJ IDEA
Open a terminal window and check your JAVA_HOME variable value:
- *nix system: echo $JAVA_HOME
- Windows system: echo %JAVA_HOME%
The JAVA_HOME path should be pointing to a different path, then set it to the openjdk-17 path:
- *nix system: export JAVA_HOME=/path/to/openjdk-17
- Windows system: set JAVA_HOME=path\to\openjdk-17
Open your project again in IntelliJ IDEA
Make sure to set both source and target compatibility versions (not only the sourceCompatibility)

You should be able to build your project.

EDIT: Gradle Toolchain

You may need also to instruct Gradle to use a different JVM than the one it uses itself by setting the Java plugin toolchain to your target version:

// build.gradle
java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(17)
    }
}

ANSWER

Answered 2021-Aug-01 at 06:17

Please note that Spring Cloud Gateway is not compatible with Spring MVC (spring-boot-starter-web). This is outlined in section "How to include Spring Cloud Gateway in the official reference documentation":

Spring Cloud Gateway is built on Spring Boot 2.x, Spring WebFlux, and Project Reactor. As a consequence, many of the familiar synchronous libraries (Spring Data and Spring Security, for example) and patterns you know may not apply when you use Spring Cloud Gateway.

Additionally, it is stated that:

Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. It does not work in a traditional Servlet Container or when built as a WAR.

As already suggested by the error message, you would need to remove the dependency on spring-boot-starter-web. You can list all your direct and transitive dependencies with the following command:

mvn dependency:tree

This will reveal that spring-cloud-starter-netflix-eureka-server depends on spring-boot-starter-web. Once you remove the following lines from your pom.xml, your application should start up:


    org.springframework.cloud
    spring-cloud-starter-netflix-eureka-server

QUESTION

Added corsConfigurationSource and still an error "has been blocked by CORS policy"

Asked 2022-Mar-02 at 19:19

I'm trying to connect Spring Security to my project. Created the Security Config class

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    private final JwtTokenProvider jwtTokenProvider;

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
    
    public SecurityConfig(JwtTokenProvider jwtTokenProvider) {
        this.jwtTokenProvider = jwtTokenProvider;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .httpBasic().disable()
                .cors().and().csrf().disable()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .authorizeRequests()

                .antMatchers("/auth/api/v1/admin/*").hasRole("ADMIN")
                .anyRequest().authenticated()
                .and()
                .apply(new JwtConfigurer(jwtTokenProvider));
    }
}

I am sending a request from the browser for registration

http://localhost:15001/auth/api/v1/user/register

and I get an answer:

Access to XMLHttpRequest at 'http://localhost:15001/auth/api/v1/user/register' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

According to the Spring documentation, I add the corsConfigurationSource method:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    private final JwtTokenProvider jwtTokenProvider;

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();

I am sending a request from the browser for registration

http://localhost:15001/auth/api/v1/user/register

and I still get the same error

Access to XMLHttpRequest at 'http://localhost:15001/auth/api/v1/user/register' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Why didn't the error disappear?

I know there is another way to add on the controller

@CrossOrigin(origins="http://localhost:4200″)

You can also add to the header. but I want to figure out why this method doesn't work.

If this is a local environment, you don't need to configure Spring, instead you modify angular configuration.

Create a file proxy.conf.json in your project's src/ folder.

Add the following content to the new proxy file:

{
  "/api": {
    "target": "http://localhost:3000",
    "secure": false
  }
}

In the CLI configuration file, angular.json, add the proxyConfig option to the serve target:

...

"architect": {
  "serve": {
    "builder": "@angular-devkit/build-angular:dev-server",
    "options": {
      "browserTarget": "your-application-name:build",
      "proxyConfig": "src/proxy.conf.json"
    },
...

To run the development server with this proxy configuration, call ng serve.

More details are here. The trouble with configuring Spring CORS is that:

you are trying to solve a development environment specific problem
this may leak CORS configuration into production setup where they aren't required unless you do actually want CORS set up.

Now, what to do in production ?

It actually depends on how you bundle your code.

If your UI + Java code is going to be in same deployable, WAR or JAR, you don't need to configure CORS because they will be deployed on same domain (https://apps.example.com) or on same context root (https://apps.example.com/app).

You do need to configure CORS when your UI and java code is not on same domain or you want apps deployed on other domains (https://apps.example.**com**) to access your APIs from their page.

Please note in Spring, when you set

configuration.setAllowCredentials(true);

Spring does not accepts:

configuration.setAllowedOrigins(Arrays.asList("*"));

You are required to configure required origins one by one like this:

configuration.setAllowedOrigins(Arrays.asList("http://localhost:4200"));

QUESTION

Spring Boot 2.6 and Angular in static Resources

Asked 2022-Mar-02 at 08:15

My question is very similar to this question that has already been asked and answered but is not 100% up-to-date.

We used the solution from Chris Gaskill for quite some time and it suited us perfectly because we wanted to redirect requests that contain more than one path segment (i.e. /foo/bar)

From Spring Boot 2.4 on, Boot uses the PathPatternParser instead of the AntPathMatcher, wherein the former does not support ** at the start of a pattern anymore (see docs).

Is there some other solution to get the same behavior? What do you use to redirect all requests, that did not match anything else, to the index.html of the Angular app?

This is the code of the controller that forwards the requests.

@Controller
class SpaRoutingController {

  @GetMapping("/**/{path:[^\\.]*}", headers = "X-Requested-With!=XMLHttpRequest")
  fun forward(): String? {
      return "forward:/"
  }
}

ANSWER

Answered 2022-Feb-23 at 15:02

Have you tried to implement redirection on Angular side? In my application I've solved this like:

const routes: Routes = [
  {path: '', redirectTo: '/myProjects', pathMatch: 'full'},
  //...
  {path: '**', redirectTo: ''}
}

@NgModule({
  imports: [
    RouterModule.forRoot(routes, {useHash: true})
  ],
  exports: [
    RouterModule
  ],
  declarations: []

export class MyRoutingModule {

GeneratePdf does not match the default name pattern for test classes. The default pattern is Test*|*Test|*Tests.

You can change it in your Gradle file with

  useJUnitPlatform()
  include '**/*Pdf'
}

QUESTION

Prometheus cannot scrape from spring-boot application over HTTPS

Asked 2022-Feb-11 at 19:34

I'm deploying a spring-boot application and prometheus container through docker, and have exposed the spring-boot /actuator/prometheus endpoint successfully. However, when I enable prometheus debug logs, I can see it fails to scrape the metrics:

ts=2022-02-02T03:54:46.210Z
caller=scrape.go:1292
level=debug
component="scrape manager"
scrape_pool=spring-actuator
target=https://127.0.0.1:8443/actuator/prometheus/
msg="Scrape failed"
err="Get \"https://127.0.0.1:8443/actuator/prometheus/\": dial tcp 127.0.0.1:8443: connect: connection refused"

I'm thinking it's something to do with how I've set up my spring-boot HTTPS. I am generating a self-signed certificate during the building of my spring-boot application, using the command:

keytool
  -genkey
  -alias 
  -dname 
  -keyalg RSA
  -keysize 4096
  -storetype PKCS12
  -keystore 
  -validity 3650
  -storepass

I then export the cert to a .pem file, and extract the .crt and .key:

openssl pkcs12 -in cert.p12 -out cert.pem -nodes -passin pass:

This is mounted through a shared volume to my prometheus container, which has a --web.config.file containing:

tls_server_config:
  cert_file: /path/to/cert.crt
  key_file: /path/to/cert.key

And for good measure I added insecure_skip_verify: true to the prometheus.yml config:

- job_name: 'spring-actuator'
metrics_path: '/actuator/prometheus/'
scrape_interval: 60s
scheme: https
static_configs:
  - targets: [ '127.0.0.1:8443' ]
tls_config:
  insecure_skip_verify: true

ANSWER

Answered 2022-Feb-07 at 22:37

Ok, I think I found my problem. I made two changes:

First, I moved the contents of the web.config.file into the prometheus.yml file under the 'spring-actuator'. Then I changed the target to use the hostname for my backend container, rather than 127.0.0.1.

The end result was a single prometheus.yml file:

- job_name: 'spring-actuator'
metrics_path: '/actuator/prometheus/'
scrape_interval: 60s
scheme: https
static_configs:
  - targets: [ 'backend:8443' ]
tls_config:
  cert_file: /path/to/cert.crt
  key_file: /path/to/cert.key
  insecure_skip_verify: true

So just some silly mistakes, not caused by the certs from what I can see. :)

Kotlin Spring Boot bean validation not working

Asked 2022-Feb-02 at 07:44

I have quite a few projects that is slowly being migrated from Java to Kotlin, but I'm facing a problem when changing from Java POJO to Kotlin data classes. Bean validation stops working in REST controllers. I have created a very simple project directly from https://start.spring.io to demonstrate the failure.

@SpringBootApplication
class RestValidationApplication

fun main(args: Array) {
    runApplication(*args)
}

@RestController
class Controller {

    @PostMapping
    fun test(@Valid @RequestBody request: Test) {
        println(request)
    }
}

data class Test(@field:NotNull val id: String)

and gradle:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
    id("org.springframework.boot") version "2.6.1"
    id("io.spring.dependency-management") version "1.0.11.RELEASE"
    kotlin("jvm") version "1.6.0"
    kotlin("plugin.spring") version "1.6.0"
}

group = "com.example"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_17

repositories {
    mavenCentral()
}

dependencies {
    implementation("org.springframework.boot:spring-boot-starter-validation")
    implementation("org.springframework.boot:spring-boot-starter-web")
    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    testImplementation("org.springframework.boot:spring-boot-starter-test")
}

tasks.withType {
    kotlinOptions {
        freeCompilerArgs = listOf("-Xjsr305=strict")
        jvmTarget = "17"
    }
}

Sending a request does not trigger the bean validation, but it throws a HttpMessageNotReadableException because id is NULL.

curl -X POST http://localhost:8080 -H "Content-Type: application/json" -d "{}"

I have tried both @Valid and @Validated and using @get:NotNull on the attributes, but nothing works. I see many others have the same problem and using a Java class from a Kotlin REST controller works. Also changing to a non data class makes validation works. Anyone know if it's possible to get bean validation working with Kotlin data classes?

I think you are just missing @Validated annotation on top of your controller class.

@SpringBootApplication
class BootValidationApplication

fun main(args: Array) {
    runApplication(*args)
}

@RestController
@RequestMapping("/api/v1")
@Validated
class CustomerController {
    @PostMapping("/customer")
    fun createCustomer(@Valid @RequestBody customer: Customer): ResponseEntity {
        return ResponseEntity.ok(customer)
    }
}


@ControllerAdvice
class CustomerExceptionHandler : ResponseEntityExceptionHandler() {

    override fun handleMethodArgumentNotValid(
        ex: MethodArgumentNotValidException,
        headers: HttpHeaders,
        status: HttpStatus,
        request: WebRequest
    ): ResponseEntity {

        val fieldErrors: List = ex.fieldErrors
        val errorMapping = fieldErrors.associate { it.field to it.defaultMessage }

        val errorDetails = ErrorDetails(
            timestamp = LocalDateTime.now(),
            message = "Validation Failed",
            details = errorMapping
        )
        return ResponseEntity(errorDetails, HttpStatus.BAD_REQUEST)
    }
}

data class Customer(
    @field:NotEmpty(message = "Mandatory field: Name is missing in Request Body") val name: String
)

data class ErrorDetails(val timestamp: LocalDateTime, val message: String, val details: Map)

The output should look something like this

ANSWER

Answered 2021-Dec-07 at 19:14

The problem is the password encoder. It is required to build the auto-configured UserDetailsService that you inject in the contructor of the class.

You can break the cycle by making the bean factory method static:

@Bean
public static BCryptPasswordEncoder bcryptPasswordEncoder() {
    return new BCryptPasswordEncoder();
}

You can also move the factory method to different configuration class. But in my opinion, your WebSecurityConfig is the canonical place for the method.
