解决方案
解决方案二：
BasisRegionBizImp.class的编译版本比运行的jvm的版本高。
解决方案三：
编译的jdk版本太高了不要使用比运行环境jdk更高的版本进行编译
解决方案四：
window--java----compilercompilercompliancelevel选取合适的jdk版本然后重新编译
解决方案五：
引用3楼aoli444的回复:
window--java----compilercompilercompliancelevel选取合适的jdk版本然后重新编译
+1
解决方案六：
1.检查下JDK版本是否支持SPRING;2.检查下SPRINGBEAN配置文件写法是否正确;是否加了事务控制,需要增加SRPING特定的包;可以先去掉比较复杂的配置行,看看启动是否报错;3,最后,参考下标准SPRING配置文档进行配置;
