SpringBoot 2 (2.1.6.RELEASE) StackOverFlowError [英] SpringBoot 2 (2.1.6.RELEASE) StackOverFlowError

问题描述

我有一个 spring boot 2 应用程序，它在 IDE (IntelliJ) 中运行时按预期启动和运行.但是，当我通过命令行 (java -jar app.jar) 运行应用程序时，出现 StackOverFlowError 异常.

I have a spring boot 2 application which starts and runs as expected when run in the IDE (IntelliJ). However, when I run the app via the commandline (java -jar app.jar), I get a StackOverFlowError exception.

@SpringBootApplication
@Configuration
@EnableAutoConfiguration
@EntityScan(basePackages="x.y.z")
@EnableJpaRepositories
@EnableTransactionManagement
@EnableAspectJAutoProxy
@EnableScheduling
@EnableAsync
@EnableRetry
@Slf4j
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

推荐答案

发现问题.这是由于 spring-boot-maven-plugin 重新打包分类器在 1.5.7 和 2.1.6 版之间发生了变化(见这里)

Found the problem. This was due to the spring-boot-maven-plugin repackage classifier changes between version 1.5.7 and 2.1.6 (see here)

我的1.5.7 pom的spring-boot-maven-plugin配置如下:

My 1.5.7 pom's spring-boot-maven-plugin was configured as follows:

<plugin>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-maven-plugin</artifactId>
  <executions>
    <execution>
    <goals>
      <goal>build-info</goal>
      <goal>repackage</goal>
    </goals>
    <configuration>
      <classifier>exec</classifier>
      <additionalProperties>
        <build.number>${buildNumber}</build.number>
      </additionalProperties>
    </configuration>
  </execution>
 </executions>
</plugin>

在升级到 spring-boot-maven-plugin:2.2.16 版本后，生成的清单没有正确的 Start-Class.>

The resulting manifest from the build, after upgrading to spring-boot-maven-plugin:2.2.16 release does not have the correct Start-Class.

Manifest-Version: 1.0
Implementation-Title: my-app
Implementation-Version: 2.1.0-SNAPSHOT
Start-Class: org.springframework.boot.loader.JarLauncher
Spring-Boot-Classes: BOOT-INF/classes/
Spring-Boot-Lib: BOOT-INF/lib/
Build-Jdk-Spec: 1.8
Spring-Boot-Version: 2.1.6.RELEASE
Created-By: Maven Archiver 3.4.0
Main-Class: org.springframework.boot.loader.JarLauncher

将 spring-boot-maven-plugin:2.2.16 更改为以下解决了该问题 - jar MANIFEST 现在包含正确的 Start-Class.

Changing the spring-boot-maven-plugin:2.2.16 to the following fixed the issue - the jar MANIFEST now contains the correct Start-Class.

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>repackage</id>
            <goals>
                <goal>build-info</goal>
                <goal>repackage</goal>
            </goals>
            <configuration>
                <classifier>exec</classifier>
                <additionalProperties>
                    <build.number>${buildNumber}</build.number>
                </additionalProperties>
            </configuration>
        </execution>
    </executions>
</plugin>

正确的MANIFEST:

Manifest-Version: 1.0
Implementation-Title: my-app
Implementation-Version: 2.1.0-SNAPSHOT
Start-Class: my.app.MainClass
Spring-Boot-Classes: BOOT-INF/classes/
Spring-Boot-Lib: BOOT-INF/lib/
Build-Jdk-Spec: 1.8
Spring-Boot-Version: 2.1.6.RELEASE
Created-By: Maven Archiver 3.4.0
Main-Class: org.springframework.boot.loader.JarLauncher

应用现在可以正常启动.

The app now starts fine.
