注解解析不到异常好像，java.lang.annotation.AnnotationFormatError: Invalid default:

整合SSM出现这么一个bug:

Caused by: java.lang.annotation.AnnotationFormatError: Invalid default: public abstract java.lang.Class org.mybatis.spring.annotation.MapperScan.factoryBean()
	at java.lang.reflect.Method.getDefaultValue(Unknown Source)

说是注解解析不到怎么怎么的，摸不清楚，百度网上，说是spring-webmvc,等的jar包与jdk版本不一致，jdk版本设置1.7，

1.5.都无效，

后来看依赖，添加了spring-jdbc依赖，却意外好了。删了又报错，不知是什么原因导致这个bug.

查bug好难。
