java.lang.NoClassDefFoundError when deploying Spring Boot .war within .ear on Wildfly with other deployments

问题

我在Wildfly上部署Spring Boot应用程序时遇到了java.lang.NoClassDefFoundError错误，该应用程序以.war文件形式打包在一个.ear部署包中。只有在.ear文件中包含其他部署时才会出现此错误。

然而，如果我将.war文件部署在一个没有其他部署的新的Wildfly实例上，就不会遇到任何问题。

详细信息:

这是我看到的具体错误消息：

ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 142) MSC000001: Failed to start service jboss.deployment.subunit."interfaces2.ear"."redacted-kafka-consumer.war".undertow-deployment: 
org.jboss.msc.service.StartException in service jboss.deployment.subunit."interfaces2.ear"."redacted-kafka-consumer.war".undertow-deployment: java.lang.RuntimeException: java.lang.IllegalStateException: Error processing con
dition on org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration.basicErrorController
    ...

这个错误似乎与Spring Framework的spring-boot-web模块中的DefaultErrorAttributes类有关。看起来类加载器无法找到必要的HandlerExceptionResolver类，导致运行时的NoClassDefFoundError错误。

附加信息:

  • Spring Boot 版本: 2.7.11
  • Wildfly 版本: 23
  • Java 版本: 11

这是redacted-kafka-consumer模块的pom.xml文件中相关的依赖项：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>

非常感谢您提供帮助或解决此问题的建议。谢谢！

I'm encountering a java.lang.NoClassDefFoundError when deploying a Spring Boot application as a .war file within a .ear deployment on Wildfly. The error only occurs when there are other deployments included in the .ear file.

However, if I deploy the .war file on a fresh Wildfly instance with no other deployments, I don't encounter any issues.

Details:

Here's the specific error message I'm seeing:

This error seems to be related to the class DefaultErrorAttributes from Spring Framework's spring-boot-web module. It appears that the class loader is unable to find the necessary class HandlerExceptionResolver, leading to the NoClassDefFoundError at runtime.

Additional Information:

  • Spring Boot version: 2.7.11
  • Wildfly version: 23
  • Java version: 11

Here are the relevant dependencies from the pom.xml file of the redacted-kafka-consumer module:

		&lt;dependency&gt;
			&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
			&lt;artifactId&gt;spring-boot-starter-web&lt;/artifactId&gt;
			&lt;exclusions&gt;
				&lt;exclusion&gt;
					&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
					&lt;artifactId&gt;spring-boot-starter-logging&lt;/artifactId&gt;
				&lt;/exclusion&gt;
			&lt;/exclusions&gt;
		&lt;/dependency&gt;
		&lt;dependency&gt;
			&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
			&lt;artifactId&gt;spring-boot-starter-log4j2&lt;/artifactId&gt;
		&lt;/dependency&gt;
		&lt;dependency&gt;
			&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
			&lt;artifactId&gt;spring-boot-starter-tomcat&lt;/artifactId&gt;
			&lt;scope&gt;provided&lt;/scope&gt;
		&lt;/dependency&gt;
		&lt;dependency&gt;
			&lt;groupId&gt;javax.servlet&lt;/groupId&gt;
			&lt;artifactId&gt;servlet-api&lt;/artifactId&gt;
			&lt;version&gt;${servlet-api.version}&lt;/version&gt;
			&lt;scope&gt;provided&lt;/scope&gt;
		&lt;/dependency&gt;

Any help or suggestions on how to resolve this issue would be greatly appreciated. Thank you!

"[加载DispatcherServlet的默认策略类错误](https://stackoverflow.com/a/20267074/6309)" 或 "[请告诉我Spring MVC错误](https://stackoverflow.com/a/45453371/6309)" 都指向模块之间的某个版本不一致。

因此，在构建war时，请仔细检查pom.xml加载的当前版本：

``` bash
mvn versions:display-dependency-updates

并检查是否有任何您可能考虑升级的更新：

mvn versions:display-dependency-updates

检查是否会在构建可交付物时，使用DependencyConvergence规则来执行 enforcer 失败：

&lt;project&gt;
  [...]
  &lt;build&gt;
    &lt;plugins&gt;
      &lt;plugin&gt;
        &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
        &lt;artifactId&gt;maven-enforcer-plugin&lt;/artifactId&gt;
        &lt;version&gt;3.3.0&lt;/version&gt;
        &lt;executions&gt;
          &lt;execution&gt;
            &lt;id&gt;enforce&lt;/id&gt;
            &lt;goals&gt;
              &lt;goal&gt;enforce&lt;/goal&gt;
            &lt;/goals&gt;
            &lt;configuration&gt;
              &lt;rules&gt;
                &lt;DependencyConvergence /&gt;
              &lt;/rules&gt;
            &lt;/configuration&gt;
          &lt;/execution&gt;
        &lt;/executions&gt;
      &lt;/plugin&gt;
    &lt;/plugins&gt;
  &lt;/build&gt;
  [...]
&lt;/project&gt;

&quot;[Error loading DispatcherServlet&#39;s default strategy class](https://stackoverflow.com/a/20267074/6309)&quot; or &quot;[Please advise to me that Spring MVC Error](https://stackoverflow.com/a/45453371/6309)&quot; are both pointing to some version discrepancy between modules.
So double-check the current versions loaded by your pom.xml when building your war:
``` bash
mvn versions:display-dependency-updates

And check if there is any update you might want to consider upgrading to:

mvn versions:display-dependency-updates

Check if an enforcer would fail your build, using a DependencyConvergence rule, when building your deliverable:

&lt;project&gt;
  [...]
  &lt;build&gt;
    &lt;plugins&gt;
      &lt;plugin&gt;
        &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
        &lt;artifactId&gt;maven-enforcer-plugin&lt;/artifactId&gt;
        &lt;version&gt;3.3.0&lt;/version&gt;
        &lt;executions&gt;
          &lt;execution&gt;
            &lt;id&gt;enforce&lt;/id&gt;
            &lt;goals&gt;
              &lt;goal&gt;enforce&lt;/goal&gt;
            &lt;/goals&gt;
            &lt;configuration&gt;
              &lt;rules&gt;
                &lt;DependencyConvergence /&gt;
              &lt;/rules&gt;
            &lt;/configuration&gt;
          &lt;/execution&gt;
        &lt;/executions&gt;
      &lt;/plugin&gt;
    &lt;/plugins&gt;
  &lt;/build&gt;
  [...]
&lt;/project&gt;
