我已经读了很多相关的文章。但都无济于事。
我正在创建一个新项目。到目前为止，我选择使用最新的稳定的Spring Boot(2.7.5与Spring Framework 5.3.23(和JDK(17(。
Spring Docs表示它是兼容的。他们说："；Spring Boot 2.7.5需要Java 8，并且兼容直至Java 19。弹簧框架5.3.23或以上也是必需的">
但是当我试着跑的时候，我得到了下面的错误。如果我降级到JDK 11，这只是一个警告，如果我降级为JDK 8，它会发出警告：
我读到vm选项可以帮助"--添加打开"；但我不清楚应该打开哪个模块。我试过"--add打开java.base/java.lang=ALL-UNNAMED"；没有成功。
问题是我有一个外部库，在这个库中，我创建了一个anotation"@日志"；使用用户Logger的实例设置本地变量。
此注释使用来自春季启动的ReflectionUtils。然后调用ReflectionUtils.makeAccessible或调用field.set。发生错误。
有人能帮我吗？

根据弹簧引导github，此处：https://github.com/spring-projects/spring-boot/pull/27089/files#diff-057b5902bc851e45308e00909e41e56c116987b78cfcab5c465bd601450396c
必须使用--add-opens=java.base/java.net=ALL-UNNAMEDJVM选项
使用Reflect访问第三方库的非公共方法通常不是一个好主意。
