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,我收到了ClassNotFound错误:
引起:org.springframework.beans.factory.BeanCreationException:在类路径资源[org / springframework / boot / autoconfigure / orm / jpa / HibernateJpaConfiguration.class]中定义名称为'entityManagerFactory'的bean创建错误:init的调用方法失败;嵌套异常是java.lang.NoClassDefFoundError:javax / transaction / SystemException
我找到了一些针对该问题的文章,并在/ src / main / kotlin下添加module-info.java
以及以下内容:
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;
}
然后我会得到Caused by: java.lang.ArrayIndexOutOfBoundsException: 32800

我实际上不知道如何解决这个问题。在另一台装有JDK 8的计算机上,它编译得很好。
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
如果没有任何更改,我会得到同样的错误。也许有人可以通过寻找它来实现它。那会很好: - )
答案 0 :(得分:5)
您需要包含从Java 9弃用的所有javaee依赖项(替代方法是将--add-modules java.se.ee
或--add-modules ALL-SYSTEM
添加到maven编译器选项以及启动应用程序的java但不建议这样做,因为类将在Java 11中消失。
1.您需要删除module-info.java文件并添加以下依赖项。
<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
我认为完整列表,您可以选择或只使用所有这些:
