后端-框架-Spring-MyBatis-整合

基础类(基础)

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

其中的配置文件

		<!-- 其中&符号用&amp;代替 -->
		<property name="driverClassName" value="com.mysql.jdbc.Driver" />

基础类(偷懒)

//SqlSessionDaoSupport支持不用自己建SqlSessionTemplate
public class UserMapperImpl extends SqlSessionDaoSupport implements UserMapper { 
	public List<User> getUserList(User user) {
		return this.getsqlSession().selectList("cn.smbms.dao.user.UserMapper.getUserList", user);
    }
}
