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

初次配置mybatis,執行時出錯,報錯資訊如下

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

後來發現原來是mybatis.xml檔案中對mapper.xml檔案引入了兩次

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>

錯誤原因:在sqlMapConfig.xml中已經引入了mapper.xml檔案,在mybatis.xml中又引入了一次

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

解決辦法:去除其中一個引入即可
