Since 2.2.0 spring-boot-maven-plugin create 2 java process (may cause CreateProcess error=206). Need workaround to fix it

问题

自 Spring Boot 2.2.0.RELEASE 起，使用 spring-boot-maven-plugin 运行应用时，可能会创建两个 Java 进程。这可能会导致类似于 https://github.com/spring-projects/spring-boot/issues/17766 的问题。在我的情况下，可能出现类似以下的进程：

14811 ? Sl 1:34 /usr/lib/jvm/java-11-oracle/bin/java -classpath ...
14841 ? Sl 8:01 /usr/lib/jvm/java-11-oracle/bin/java -Xverify:none ...

这种情况可能会引发 Windows 下的“错误 CreateProcess error=206，文件名或扩展名过长”的问题（参考链接：https://stackoverflow.com/questions/54246648/jhipster-5-7-microservice-failed-to-start-on-windows-with-error-createprocess-er）。

为了解决这个问题，你可以采取以下方式之一（不包括回退到之前的版本）：

  1. 使用短路径和文件名：尝试将 Maven 仓库和项目路径放在较短的目录中，以减少文件路径长度。例如，将 Maven 仓库和项目移动到根目录下的一个短目录。

  2. 将依赖项提取到外部目录：将一些大型依赖项（例如，JAR 包）从类路径中提取到一个外部目录，然后通过 -classpath 参数引用它们。

  3. 使用更短的类路径：通过删除一些不必要的依赖项，减小类路径的长度。

  4. 使用可执行的 JAR 文件：使用 Spring Boot 可执行的 JAR 文件，这样可以将所有依赖项打包在一个 JAR 中，减少类路径的长度。

  5. 分离应用：将应用拆分成更小的模块，每个模块有自己的依赖项，以减少单个模块的类路径长度。

  6. 使用类路径通配符：在类路径中使用通配符来引用一组相关的 JAR 包，从而减少类路径的长度。

  7. 检查不必要的依赖项：检查是否有一些不必要的依赖项，可以移除它们以减少类路径长度。

请选择适合你项目的方法来解决这个问题。

Since Spring Boot 2.2.0.RELEASE spring-boot-maven-plugin

mvn spring-boot:run -Drun.profiles=prod

create two java process (see https://github.com/spring-projects/spring-boot/issues/17766). In my case:

It is too verbose and for Windows could cause of "error CreateProcess error=206, The filename or extension is too long" (see https://stackoverflow.com/questions/54246648/jhipster-5-7-microservice-failed-to-start-on-windows-with-error-createprocess-er).

What is the best way to fix it (exclude return to previous version:)?

答案1

得分: 15

显然，自从Spring Boot 2.2以来，默认情况下启用了forking。

要禁用它，可以尝试以下方法：

在您的Maven命令中添加 -Dspring-boot.run.fork=false，或者在您的pom.xml中进行配置：

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <fork>false</fork>
    </configuration>
</plugin>
英文:

Apparently, forking is enabled by default since Spring Boot 2.2.

Disable it again might help.

Add -Dspring-boot.run.fork=false to your maven command or configure it in your pom.xml:

&lt;plugin&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-maven-plugin&lt;/artifactId&gt;
&lt;configuration&gt;
&lt;fork&gt;false&lt;/fork&gt;
&lt;/configuration&gt;
&lt;/plugin&gt;
