hibernate - Spring Boot 2/Kotlin/JDK9 - 由 : java. lang.ClassNotFoundException : javax. transaction.SystemException 引起

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 spring-boot-starter-data-jpa 后出现 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

我其实不知道如何解决这个问题。在另一台装有 JDK 8 的计算机上，它可以正常编译。

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

您需要包括所有从 Java 9 弃用的 javaee 依赖项(或者添加 --add-modules java.se.ee 或 --add-modules ALL-SYSTEM 到 maven 编译器选项和 java 启动应用程序，但不推荐这样做，因为类将在 Java 11 中消失。

1.需要移除module-info.java文件，添加下面的依赖

1. 在 maven 中添加一个属性(因为 surefire/failsafe 2.20.1 有一个 bug 阻止在 Java 9 中正确运行测试):

<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，您可以挑选或使用所有的列表:
