UserDao: package com.cfdcn.demoweb.dao; import org.apache.ibatis.session.SqlSessionFactory; import org.mybatis.spring.support.SqlSessionDaoSupport; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import com.cfdcn.demoweb.entity.User; @Component public class UserDao extends SqlSessionDaoSupport { @Autowired public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) { super.setSqlSessionFactory(sqlSessionFactory); } public User selectById(int id) { return this.getSqlSession().selectOne("com.cfdcn.demoweb.UserMapper.selectById", id); } }

这样配置：

	<!-- 配置mybitasSqlSessionFactoryBean -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="configLocation" value="classpath:mybatis-config.xml"></property>
		<property name="dataSource" ref="dataSource" />
	</bean>

	<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
		<constructor-arg index="0" ref="sqlSessionFactory" />
		<constructor-arg index="1" value="BATCH" />
	</bean>

	@Resource(name = "sqlSession")
	private SqlSession sqlSession;

	public SqlSession getSqlSession() {
		return sqlSession;
	}

datasource在什么文件里配置的，放到主配置文件里。

楼上说的有道理

[大刘_南京]

找到原因了，是xml配置文件里写的不对！
