JDK16下，使用LambdaQueryWrapper条件查询报错 #3883

Closed fanyawei closed 2 years ago

fanyawei commented 3 years ago

当前使用版本(必填,否则不予处理)

mybatis-plus：3.4.3.2 jdk:oraclejdk-16.0.2 springboot:2.5.4

该问题是如何引起的？(确定最新版也有问题再提!!!)

最新稳定版本3.4.3.2,启动时候不加指定参数,LambdaQueryWrapper条件查询还是报错

重现步骤(如果有就写完整)

JDK9 模块化引起的问题

但是使用JDK11都没问题啊

marshalby2 commented 3 years ago

我也遇到了

请问你解决了吗

hcl04 commented 3 years ago

模块化的内容需要你们自己测试以下，JDK11 虽然在 Method 和 Field 中的 setAccessible 加入了检查：if (flag) checkCanSetAccessible(Reflection.getCallerClass());，但模块是 open 的，因此没有错误。

在 JDK16 中这些模块默认不再是 open 了，因此可以预见，当你试图反射任何未开放给当前模块的非公共成员，都会有一个 java.lang.ExceptionInInitializerError 抛出。

上个修复方法之中，我们错误的认为会抛出一个 java.lang.reflect.InaccessibleObjectException，因为不同版本之间的JDK测试存在一定难度，我们大意了。不过最近我们已经在昨天修复了这个问题，下次更新就会修复该问题。

也遇到了,不过常规的new QueryWrapper没有受到影响

降回老版本也能暂时避免问题,比如3.4.0

JDK11运行会提示反射的access警告，可以正常使用，并且提示下一版本将会denied反射机制。JDK16属于JDK11之后的版本，无法正常使用反射机制获取Entity中private成员。建议使用JDK1.8或11版本来和MyBatis进行搭配。
