Hibernate java 10

Question

我将我的应用程序从java 8迁移到java 10.但是现在我在尝试将某些东西存储在数据库中时看到以下异常

我使用以下依赖项

<spring.version>4.3.18.RELEASE</spring.version>
<spring-boot.version>1.5.14.RELEASE</spring-boot.version>
<hibernate-core.version>5.3.2.Final</hibernate-core.version>
<java.version>1.10</java.version>

Answer 1

这是根本原因

Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make field private jdk.internal.reflect.ConstructorAccessorImpl jdk.internal.reflect.DelegatingConstructorAccessorImpl.delegate accessible: module java.base does not "opens jdk.internal.reflect" to unnamed module @55283c54

Java 10具有模块的概念,并且首先public不再是"那个"公共,并且反射也不那么强大.

你可以使用@RobertHume建议的JVM标志,但事实上你需要迁移到支持Java9/10的新的Hibernate版本(如果有的话).
