这次原因全找着了，*Mapping.xml都存在重复resultMap，在开始使用Mybatis-plugin时出现了故障。。。

@Service注解有写，在控制层也注入了
@Service("iUserService")@Autowired private IUserService iUserService;

心大心大。。粗心大意找到xml报错原因：userMappper.xml中，因为之前copy不小心copy了全文，出现了两个一样的内容。。。删除搞定。可是tomcat启动还是保错，错误信息一样。

你好同学，原因应该是在autowire时，找不到相应的类，上述问题是因为XXXXX的实现类中没有加相应的注解。如dao层 @Repository 如service层 @Service，排查一下看看。
