Daoimpl层里面继承SqlSessionDaoSupport，可以简化代码，直接获取到SqlSession，

SqlSessionDaoSupport里面有setSqlSessionFactory可以进行设值注入。

public class UserMapperImpl extends SqlSessionDaoSupport implements UserMapper {
	
/*	  
	private SqlSessionTemplate sqlSession;
    public void setSqlSession(SqlSessionTemplate sqlSession) {
        this.sqlSession = sqlSession;
    }*/
    @Override
    public List<User> getUserList(User user) {
    	//使用SqlSessionTemplate
        //return sqlSession.selectList("cn.smbms.dao.user.UserMapper.getUserList", user);
    	//使用SqlSessionDaoSupport
    	return this.getSqlSession().selectList("cn.smbms.dao.user.UserMapper.getUserList", user);
    }

    /*public SqlSessionTemplate getSqlSession() {
        return sqlSession;
    }

　　更改applicationContext.xml
