Mybatis增删改查以及Dao的写法

增加：

单条增加xml

DAO

public int insert(WycjwdjlTemp wycjwdjlTemp) {
        return sessionTemplate.insert("addWycjwdjlTemp", wycjwdjlTemp);
    }

XML

        INSERT INTO wycjwdjl_temp (recordid, lng, lat, gpstime, speed, isabled,direction,remark)
        VALUES (#{recordid},#{lng},#{lat},#{gpstime},#{speed},#{isabled},#{direction},#{remark})
    

*************************************************************************************************************************************

批量增加xml：

DAO：

 public int insert(List wycjwdjlTemps) {
        return sessionTemplate.insert("addWycjwdjlTempBatch", wycjwdjlTemps);
    }

XML

    
        INSERT INTO wycjwdjl_temp (recordid, lng, lat, gpstime, speed, isabled,direction,remark) values
        
            (#{item.recordid},#{item.lng},#{item.lat},#{item.gpstime},#{item.speed},#{item.isabled},#{item.direction},#{item.remark})
        
    

*************************************************************************************************************************************

查询：

DAO：

public UserDacheReceipt findUserDacheReceiptByrecordId(long recordId) {
		UserDacheReceipt userDacheReceipt=sessionTemplate.selectOne("findUserDacheReceiptByrecordId",recordId);
		return userDacheReceipt;
	}

DAO list；

public List findUserDacheReceiptByrecordId(long recordId) {
		List userDacheReceipts=sessionTemplate.selectList("findUserDacheReceiptByrecordId",recordId);
		return userDacheReceipts;
	}

XML

 
     
     	SELECT * FROM user_dache_receipt WHERE recordId = #{recordId}
     

*************************************************************************************************************************************

更新：

DAO

public int update(UserDache userDache) {
        return sessionTemplate.update("editDacheUser", userDache);
    }

xml

     
     	UPDATE `user_dache_info` SET  `username`=#{username}, `tel`=#{tel}, `sex`=#{sex} WHERE openid=#{openid};
     

*****************************************************************************************************************************************************

删除

DAO

 public void del(int id) {
        sessionTemplate.delete("delDacheUser", id);
    }

xml

     
     	DELETE FROM user_dache_info where id=#{id}
     

*****************************************************************************************************************************************************

批量查询、模糊查询和时间段查询

DAO

public List findUsers(String starttime,String endtime,String username,String tel) {
        Map map=new HashMap();
        map.put("startTime",starttime);
        map.put("endTime",endtime);
        map.put("username",username);
        map.put("tel",tel);
        List list = sessionTemplate.selectList("findUsers",map);
        return list;
    }

xml

    
        select * from user_dache_info
         
  
	    1 = 1//一定能执行，为了关联后面的ADN，不然会报错
             AND createTime >= #{startTime} 
             AND createTime <= #{endTime} 
             AND username LIKE CONCAT ('%',#{username},'%' ) 
             AND tel LIKE CONCAT('%',#{tel},'%' )
