because it is a JDK dynamic proxy that implements 报错

在Spring boot项目中出现以下报错:

Description:
The bean ‘xxx’ could not be injected as a ‘xxx’ because it is a JDK dynamic proxy that implements:
tk.mybatis.mapper.common.Mapper
Action:
Consider injecting the bean as one of its interfaces or forcing the use of CGLib-based proxies by setting proxyTargetClass=true on @EnableAsync and/or @EnableCaching.

查阅资料发现是@Resource注解引起的

@Autowired按byType自动注入，而@Resource默认按 byName自动注入

按照平时用@Autowired注解的习惯，习惯命名方式

@Resource
private UserMapper userMapper；

@Resource
private YjjUserMapper userMapper；

我的项目中userMapper在两个地方出现了，但是却是不同的类型，@Resource就会按照UserMapper 类型自动注入，于是报错了，此时将第二个userMapper改为yjjUserMapper 就好了
