java.lang.IllegalArgumentException: Mapped Statements collection already contains value for xxx.xxx

初次配置mybatis,运行时出错,报错信息如下

java.lang.IllegalArgumentException: Mapped Statements collection already contains value for xxx.xxx.dao.methodname

后来发现原来是mybatis.xml文件中对mapper.xml文件引入了两次

以下是我的配置:

mybatis.xml配置sqlSessionFactory

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="configLocation" value="classpath:sqlMapConfig.xml"/>
    <property name="mapperLocations" value="classpath:sqlmap/*.xml"/>
</bean>

sqlMapConfig.xml引入mapper.xml

<mappers>
    <mapper resource="sqlmap/ResultSqlMap.xml"/>
</mappers>

错误原因:在sqlMapConfig.xml中已经引入了mapper.xml文件,在mybatis.xml中又引入了一次

<property name="mapperLocations" value="classpath:sqlmap/*.xml"/>

解决办法:去除其中一个引入即可
