不知道楼主的问题是不是和我一样。我出现这个问题是因为mappers重复加载。
问题位置：在spring的配置文件中加载mappers的配置重复，applicationContext.xml问题配置如下：
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource">
<ref bean="oracleDataSource" />
</property>
<property name="configLocation">
<value>classpath:org/bss/config/db/mybatisConfig.xml</value>
</property>
<!-- ① 加载所有mapper 于位置②发生冲突，mapper被重复加载
<property name="mapperLocations">
<value>classpath:org/bss/dao/mappers/*.xml</value>
</property>
-->
</bean>

<!--② 为dao接口装载mapper -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="org.bss.dao.iface" />
</bean>
