QUESTION
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?
ANSWER
Answered 2021-Dec-09 at 15:51Known 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
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 12:36This 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.

ANSWER
Answered 2021-Oct-24 at 14:23The 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%
- *nix system:
- 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
- *nix system:
- 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 ToolchainYou 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 06:17Please 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
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 SecurityConfig(JwtTokenProvider jwtTokenProvider) {
this.jwtTokenProvider = jwtTokenProvider;
}
@Override

.cors().and().csrf().disable()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
.antMatchers("/auth/api/v1/user/register").permitAll()
.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:

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();
}
public SecurityConfig(JwtTokenProvider jwtTokenProvider) {
this.jwtTokenProvider = jwtTokenProvider;
}
@Bean
CorsConfigurationSource corsConfigurationSource() {
CorsConfiguration configuration = new CorsConfiguration();
configuration.setAllowedOrigins(Arrays.asList("http://localhost:4200"));
configuration.setAllowedMethods(Arrays.asList("GET","POST"));
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", configuration);
return source;
}

.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 still get the same error

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.

ANSWER
Answered 2022-Mar-02 at 19:19If 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
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 15:02Have 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 {
}

QUESTION
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 22:37Ok, 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. :)

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?
ANSWER
Answered 2021-Dec-16 at 07:38I think you are just missing @Validated annotation on top of your controller class.
import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.boot.runApplication
import org.springframework.http.HttpHeaders
import org.springframework.http.HttpStatus
import org.springframework.http.ResponseEntity
import org.springframework.validation.FieldError
import org.springframework.validation.annotation.Validated
import org.springframework.web.bind.MethodArgumentNotValidException
import org.springframework.web.bind.annotation.*
import org.springframework.web.context.request.WebRequest
import org.springframework.web.servlet.mvc.method.annotation.ResponseEntityExceptionHandler
import java.time.LocalDateTime
import javax.validation.Valid
import javax.validation.constraints.NotEmpty
@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)
QUESTION
I am unable to update my spring boot app to 2.6.0 from 2.5.7. It throws the following error.
2021-12-07T08:40:22,311 ERROR [restartedMain] o.s.b.SpringApplication.reportFailure:819|| Application run failed org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'webSecurityConfig':
The requested bean is currently in creation: Is there an unresolvable circular reference?
at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.beforeSingletonCreation(DefaultSingletonBeanRegistry.java:355)
at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:227)
From the spring-boot 2.6.0 release notes, it is clear that circular references are disabled. And it can be enabled back with the property spring.main.allow-circular-references = true
. But I would like to fix the circular reference in the first place. Can anyone help me troubleshoot this issue? Please find the WebSecurityConfig class below,
@Configuration
@EnableWebSecurity
@SuppressWarnings({"PMD.SignatureDeclareThrowsException"})
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
private final UserDetailsService userDetailsService;
public WebSecurityConfig(final UserDetailsService userDetailsService) {
this.userDetailsService = userDetailsService;
}
@Bean
public BCryptPasswordEncoder bcryptPasswordEncoder() {
return new BCryptPasswordEncoder();
}
@Override
protected void configure(final HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/resources/**", "/registration", "/css/**", "/js/**", "/h2-console/*").permitAll()
.anyRequest().authenticated().and()
.formLogin()
.loginPage("/login").permitAll().and()
.headers()
.frameOptions().sameOrigin().and()
.logout()
.permitAll().and()
.requiresChannel()
.requestMatchers(r -> r.getHeader("X-Forwarded-Proto") != null)
.requiresSecure();
}
@Autowired
public void configureGlobal(final AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(bcryptPasswordEncoder());
}
}
My code is open-sourced and can be found at https://github.com/surajcm/Poseidon, I will try to troubleshoot on my own and will share the updates if I am able to resolve this issue
ANSWER
Answered 2021-Dec-07 at 19:14The 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.
