运行Tomcat 报错Caused by: java.lang.UnsupportedClassVersionError: com/bzu/service/Ac_adminService has b

                写好的的javaweb项目放windows服务器中的Tomcat中的webapps目录下

启动Tomcat报

    Caused by: java.lang.UnsupportedClassVersionError: com/bzu/service/Ac_adminService has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0 (unable to load class [com.bzu.service.Ac_adminService])

访问jsp页面显示404

            我把服务器中的jdk换成和编译javaweb项目的jdk一样的版本

启动Tomcat和访问网页正常
