java-spring 错误 Unsupported class file major version 57

环境

ubuntu 18.04 jdk13

错误代码

Caused by: org.springframework.core.NestedIOException: ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet: file ;

nested exception is java.lang.IllegalArgumentException: Unsupported class file major version 57

解决方法

jdk13暂时不被支持,降级至jdk11,可正常运行

降级方法(IDEA)

• File->Project Structure->Project->

  • Porject Sdk 选择11
