Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: ‘file [C:\Users\82784\IdeaProjects\spring-study\spring-10-mybatis\target\classes\com\fj\dao\UserMapper.xml]’;

IllegalArgumentException: Mapped Statements collection already contains value for com.fj.dao.UserMapper.selectUser. please check com/fj/dao/UserMapper.xml and file [C:\Users\82784\IdeaProjects\spring-study\spring-10-mybatis\target\classes\com\fj\dao\UserMapper.xml]

这两个错误在我整合mybatis-spring时遇到了，整了很久还是没有解决，第二天突然发现我在UserMapper.xml和spring-dao.xml文件中都绑定了同一个UserMapper接口，所以才导致报错

UserMapper.xml中

<mappers> <mapper class="com.fj.dao.UserMapper"/> </mappers>

spring-dao.xml中

<!-- 绑定Mybatis配置文件 --> <property name="configLocation" value="classpath:mybatis-config.xml"/> <property name="mapperLocations" value="classpath:com/fj/dao/*.xml"/>
