Spring Boot 2/Kotlin/JDK9 - 原因：java.lang.ClassNotFoundException：javax.transaction.SystemException

Question

实际上我正在使用 Kotlin 开发 Spring Boot v2 应用程序。我在版本 9 中使用 JDK。

添加依赖项后 spring-boot-starter-data-jpa 我收到 ClassNotFound 错误：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: javax/transaction/SystemException

我找到了一些关于该问题的文章，并在 /src/main/kotlin 下添加了一个 module-info.java，内容如下：

    module de.sample.backend {

//    requires java.xml.bind;
    requires javax.transaction.api;
//    requires validation.api;
    requires hibernate.jpa;
//    requires hibernate.validator;
    requires spring.beans;
    requires spring.core;
    requires spring.context;
    requires spring.tx;
    requires spring.web;
    requires spring.webmvc;
    requires spring.data.commons;
    requires spring.data.jpa;
    requires spring.boot;
    requires spring.boot.autoconfigure;
//    requires cache.api;

}

但是我会得到一个 Caused by: java.lang.ArrayIndexOutOfBoundsException: 32800

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project naehmeisterei-services: Execution default-compile of goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile failed: 32800 -> [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project naehmeisterei-services: Execution default-compile of goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile failed: 32800 at org.apache.maven.lifecycle.internal.MojoExecutor.execute (MojoExecutor.java:213) at org.apache.maven.lifecycle.internal.MojoExecutor.execute (MojoExecutor.java:154) at org.apache.maven.lifecycle.internal.MojoExecutor.execute (MojoExecutor.java:146) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject (LifecycleModuleBuilder.java:117) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject (LifecycleModuleBuilder.java:81) at org.apache.maven.lifecycle.internal.builder.singlethreaded.SingleThreadedBuilder.build (SingleThreadedBuilder.java:51) at org.apache.maven.lifecycle.internal.LifecycleStarter.execute (LifecycleStarter.java:128) at org.apache.maven.DefaultMaven.doExecute (DefaultMaven.java:309) at org.apache.maven.DefaultMaven.doExecute (DefaultMaven.java:194) at org.apache.maven.DefaultMaven.execute (DefaultMaven.java:107) at org.apache.maven.cli.MavenCli.execute (MavenCli.java:955) at org.apache.maven.cli.MavenCli.doMain (MavenCli.java:290) at org.apache.maven.cli.MavenCli.main (MavenCli.java:194) at jdk.internal.reflect.NativeMethodAccessorImpl.invoke0 (Native Method) at jdk.internal.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:62) at jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke (Method.java:564) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced (Launcher.java:289) at org.codehaus.plexus.classworlds.launcher.Launcher.launch (Launcher.java:229) at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode (Launcher.java:415) at org.codehaus.plexus.classworlds.launcher.Launcher.main (Launcher.java:356) Caused by: org.apache.maven.plugin.PluginExecutionException: Execution default-compile of goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile failed: 32800

我其实不知道怎么解决那个问题。在另一台 JDK 8 的计算机上编译正常。

有人可以帮忙吗？

谢谢！

更新

我使用 spring initialzr 创建了一个新的 spring-boot 项目： https://github.com/Chris81T/spring-boot-jdk9-kotlin-demo

如果不做任何更改，我会得到同样的错误。也许有人可以寻找它来让它工作。那就太好了:-)

Answer 1

您需要包括从 Java 9 中弃用的所有 javaee 依赖项（或者将 --add-modules java.se.ee 或 --add-modules ALL-SYSTEM 添加到 Maven 编译器选项并添加java 启动应用程序但不推荐，因为类将在 Java 11).

1.You 需要删除 module-info.java 文件并添加下面的依赖项。

在 maven 中添加一个属性（因为 surefire/failsafe 2.20.1 有一个 bug 阻止运行在 Java 9 中进行正确的测试：

<properties>                                                                
    <argLine>--add-modules java.base</argLine>
 </properties>

或者您可以切换到 surefire 2.21.0 - 请参阅 http://maven.apache.org/surefire/maven-surefire-plugin/java9.html

这是我认为的完整列表，您可以挑选或全部使用：
