Answer 2

System.setProperty("io.netty.noUnsafe","true");

Answer 3

运行失败

Answer 4

这个加不加，实际上并不影响你的服务运行。你把netty的日志等级降到INFO就看不到这个异常信息了。

Answer 5

怎么加 我试了不行

Answer 6

加上一个JVM参数试试

--add-exports=java.base/jdk.internal.misc=ALL-UNNAMED

 

Answer 7

这个是 netty的问题，和spring-boot没有直接关系

Answer 8

换下jdk版本试试
