配置文件在楼上 PeaceLoop 2015-05-18 打赏举报 回复 引用 5 楼 shijing266 的回复:按道理接口是可以被多个接口继承的，出现expected single matching bean but found 2 说明父类被注解了两次

其实我以前搭过一遍mybatis的框架

最近借着struts2换springmvc的关系 我又重新搭了一遍并做了一些地方的优化

配置文件貌似也没啥问题

我把整个配置文件放在以前的项目里也不报错

实在不知道咋整

其实我以前也遇到过这个问题 那时候试了好多种方法 最后不知道怎么的莫名其妙就好了。。。

我没写类，只写了三个接口。就会出现这种问题。mybatis不需要写类。 PeaceLoop 2015-05-18 打赏举报 回复 具体代码

public interface BaseMapper {

/**

* 根据实体非空字段条件进行查询

*

* @param t

* @return

*/

public List select(T t);

//略

}

public interface UserMapper extends BaseMapper {

}

只要再多写一个XxxMapper就会报错 执笔记忆的空白 2015-05-18 打赏举报 回复 你两个子类实现了同一个接口，然后都用@Autowired去注解，是这个意思吧？
