JUnit报错nested exception is org.springframework.core.NestedIOException: ASM ClassReader failed to...

1） 环境： java Spring MVC

       使用JUnit执行单元测试的脚本

2）执行报错

3）分析：报错信息主要为：nested exception is 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

      上网搜索了一下答案： http://stackoverflow.com/questions/22526695/java-1-8-asm-classreader-failed-to-parse-class-file-probably-due-to-a-new-java/23352356#23352356

       

        4）解决：在mvn管理的pom.xml中分析  spring框架使用的脚本，

              然后需要将使用的spring框架的版本设置为3.2.9以上的版本。（作者修改到了spring 4.2.5 RELEASE ）

             如果报错的为persistent工程，但是该工程的jar应用只通用的工程tools,那么需要修改该toos工程spring的版本，然后重新打jar包。

             最后再打persistent工程的jar包。

 

        问题解决！
