An illegal reflective access operation has occurred

启动Spring Boot 项目突然看到下面的警告内容

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.springframework.cglib.core.ReflectUtils (file:/D:/maven_res/org/springframework/spring-core/5.2.8.RELEASE/spring-core-5.2.8.RELEASE.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain)
WARNING: Please consider reporting this to the maintainers of org.springframework.cglib.core.ReflectUtils
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

我还以为怎么了，原因是idea默认使用了jdk 11，项目使用的是jdk1.8.将11调整为1.8即可


调整后

spring boot jdk版本过高警告
