springmvc项目启动报错 nested exception is org.springframework.core.NestedIOException

学习springmvc的时候demo启动报错：

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [/Users/zhanglingxiang/IdeaProjects/springmvc_hellow/out/artifacts/springmvc_hellow_war_exploded/WEB-INF/classes/com/model/HelloController.class]; 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: file [/Users/zhanglingxiang/IdeaProjects/springmvc_hellow/out/artifacts/springmvc_hellow_war_exploded/WEB-INF/classes/com/model/HelloController.class]; nested exception is java.lang.IllegalArgumentException

网上查了下是java版本的问题

查找了下mac java安装目录，命令：

/usr/libexec/java_home -V

修改工程jdk版本和intellig ide里面tomcat里的jdk配置，改为1.7，依旧不行。

觉得切换了jdk后应该要重新编译，so recompile，成功了！
