springboot2/Kotlin/JDK9——由以下原因引起：java。lang.ClassNotFoundException:javax。交易系统例外

Question

实际上，我正在使用Kotlin开发SpringBootV2应用程序。我在版本9中使用JDK。

在添加了依赖项sping-boot-starter-data-jpa后，我得到了ClassNot找到错误：

原因：org。springframework。豆。工厂BeanCreationException:创建名为“entityManagerFactory”的bean时出错，该bean在类路径资源[org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]中定义：调用init方法失败；嵌套的异常是java。lang.NoClassDefFoundError:javax/transaction/SystemException

我找到了一些关于这个问题的文章，并在/src/main/kotlin下添加了模块信息。具有以下内容的java：

    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;

}

但是接下来我会得到一个由java引起的。lang.ArrayIndexOutOfBoundsException:32800

[错误]无法执行目标组织。阿帕奇。专家插件：maven编译器插件：3.7.0:ProjectNaehmeisterei服务上的编译（默认编译）：目标组织的执行默认编译。阿帕奇。专家插件：maven编译器插件：3.7.0:编译失败：32800-

这是我完整的pom.xml

我实际上不知道如何解决那个问题。在另一台使用JDK 8的计算机上，它可以很好地编译。

有人能帮忙吗？

谢谢

更新

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

没有任何变化，我将得到同样的错误。也许有人可以找到它来让它工作。那就太好了：-）

Answer 1

您需要包含所有从Java9弃用的javaee依赖项（替代方法是添加--add-模块java.se.ee或--add-模块ALL-SYSTEM到maven编译器选项和java启动应用程序，但不推荐，因为类将在Java11）。

1.您需要删除module-info.java文件并添加下面的依赖项。

<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
