QUESTION
As mentioned in the title I can't update my webapp to Spring Boot 2.6.0. I wrote my webapp using Spring Boot 2.5.5 and everything works perfectly. If I update the pom.xml file with this new tag:

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
...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.
...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:
QUESTION
I got this below error when run the API-GATEWAY, I tried so many ways but I couldn't solve this issue.
Description:
Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway.
Action:
Please set spring.main.web-application-type=reactive or remove spring-boot-starter-web dependency.
Main Class
...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:
QUESTION
Springfox 3.0.0 is not working with Spring Boot 2.6.0, after upgrading I am getting the following error
...ANSWER
Answered 2021-Dec-01 at 02:17I know this does not solve your problem directly, but consider moving to springdoc which most recent release supports Spring Boot 2.6.0. Springfox is so buggy at this point that is a pain to use. I've moved to springdoc
2 years ago because of its Spring WebFlux support and I am very happy about it. Additionally, it also supports Kotlin Coroutines, which I am not sure Springfox does.
If you decide to migrate, springdoc
even has a migration guide.
QUESTION
I am running a Spring Boot app that uses WebClient for both non-blocking and blocking HTTP requests. After the app has run for some time, all outgoing HTTP requests seem to get stuck.
WebClient is used to send requests to multiple hosts, but as an example, here is how it is initialized and used to send requests to Telegram:

...ANSWER
Answered 2021-Dec-20 at 14:25I would propose to take a look in the RateLimiter direction. Maybe it does not work as expected, depending on the number of requests your application does over time. From the Javadoc for Ratelimiter: "It is important to note that the number of permits requested never affects the throttling of the request itself ... but it affects the throttling of the next request. I.e., if an expensive task arrives at an idle RateLimiter, it will be granted immediately, but it is the next request that will experience extra throttling, thus paying for the cost of the expensive task." Also helpful might be this discussion: github or github
I could imaginge there is some throttling adding up or other effect in the RateLimiter, i would try to play around with it and make sure this thing really works the way you want. Alternatively, consider using Spring @Scheduled to read from your queue. You might want to spice it up using embedded JMS for further goodies (message persistence etc).
QUESTION
I'm upgrading from JDK 8 to JDK 17 and I'm trying to compile with mvn clean install -X -DskipTests
and there's no information about the error.
Btw, I'm updating the dependencies and after that I compile to see if has errors. I need to update some dependencies such as Spring, Hibernate etc. I already updated Lombok.
I added the -X or -e option but I got the same result.
What can I do to get more information about the error? The log shows that it was loading hibernate-jpa-2.1-api before failed... so that means the problem is in this dependency?
...ANSWER
Answered 2021-Oct-19 at 20:28This failure is likely due to an issue between java 17 and older lombok versions. Building with java 17.0.1, lombok 1.18.20 and maven 3.8.1 caused a vague "Compilation failure" for me as well. I upgraded to maven 3.8.3 which also failed but provided this detail on the failure:
java.lang.NullPointerException: Cannot read field "bindingsWhenTrue" because "currentBindings" is null
Searching for this failure message I found this issue on stackoverflow leading me to a bug in lombok. I upgraded to lombok 1.18.22 and that fixed the compilation failure for a successful build.
QUESTION
I tried to upgrade my data-mongo example project to Spring Boot 2.6.0. There is a test designed to run against Testcontainers, I also included the embedded mongo dep for other tests, so I have to exclude the AutoConfiguration for embedded mongo to make sure this test working on Docker/testcontainers.
The following configuration worked well with Spring Boot 2.5.6.
...ANSWER
Answered 2021-Nov-20 at 17:20As of Spring Boot 2.6, the property spring.mongodb.embedded.version
must be set to use the auto-configured embedded MongoDB. It's mentioned in the release notes: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.6-Release-Notes#embedded-mongo
This is also what the error message you posted, advises to do: Set the spring.mongodb.embedd ed.version property or define your own MongodConfig bean to use embedded MongoDB
The annotation @DataMongoTest
is meta-annotated with @ImportAutoConfiguration
and @AutoConfigureDataMongo
, and is designed to trigger auto-configuration of MongoDB unless explicitly disabled as you do in the working configuration examples.
In your first configuration example, the annotation @EnableAutoConfiguration(exclude = EmbeddedMongoAutoConfiguration.class)
does not override this effect of @DataMongoTest
.
With Spring Boot 2.5.6, the auto-configured MongodConfig
bean is most likely also part of the application context but not effectively used. But this depends on the rest of the code and in particular on the MongodbContainerInitializer
.

Install spring
You can use spring like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the spring component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
