mybatis多参数传递到Mapper.xml中

MyBatis3-传递多个参数（Multiple Parameters）
Mybatis传多个参数（四种解决方案）
据我目前接触到的传多个参数的方案有三种。
第一种方案：一个一个参数传递
DAO层的函数方法
User selectUser(String name,String area);
对应的Mapper.xml
<select id="selectUser" resultMap="BaseResultMap">
SELECT
*
FROM
user_user_t
WHERE
user_name = #{0} and
user_area = #{1}
</select>
其中，#{0}代表接收的是dao层中的第一个参数，#{1}代表dao层中第二参数，更多参数一致往后加即可。
第二种方案：采用Map传多参数
Dao层的函数方法
User selectUser(Map paramMap);
对应的Mapper.xml
<select id=" selectUser" resultMap="BaseResultMap">
SELECT
*
FROM
user_user_t
WHERE
user_name = #{userName，jdbcType=VARCHAR}
AND user_area = #{userArea,jdbcType=VARCHAR}
</select>
Service层调用
private User xxxSelectUser(){
Map paramMap=new hashMap();
paramMap.put(“userName”,”对应具体的参数值”);
paramMap.put(“userArea”,”对应具体的参数值”);
User user=xxx. selectUser(paramMap);
}
个人认为此方法不够直观，见到接口方法不能直接的知道要传的参数是什么。
第三种方案：直接传递对象
Dao层的函数方法
int insert(WaterEle record);
对应的Mapper.xml
<!--测试-->
<insert id="insert" parameterType="com.jsptpd.gayg.modules.cloud.model.WaterEle">
insert into t_enterprise_water_ele (WATER_ELE_ID, ENTERPRISE_ID, ENTERPRISE_NAME,
YEARMONTH, WATER_SIZE, WATER_AMOUNT,
ELE_SIZE, ELE_AMOUNT, STATUS,
OPERATOR, OPERATE_TIME)
values (#{waterEleId,jdbcType=VARCHAR}, #{enterpriseId,jdbcType=VARCHAR}, #{enterpriseName,jdbcType=VARCHAR},
#{yearmonth,jdbcType=VARCHAR}, #{waterSize,jdbcType=DECIMAL}, #{waterAmount,jdbcType=VARCHAR},
#{eleSize,jdbcType=DOUBLE}, #{eleAmount,jdbcType=VARCHAR}, #{status,jdbcType=INTEGER},
#{operator,jdbcType=VARCHAR}, #{operateTime,jdbcType=TIMESTAMP})
</insert>
Service层调用
@RequestMapping(value = "", method = RequestMethod.POST)
public ResponseObj<Boolean> insert(@RequestBody WaterEle waterEle) {
//先查询是否有这条数据，没有进行插入操作
WaterEle enterpriseBase1 = waterEleMapper.selectByPrimaryKey(waterEle.getWaterEleId());
if (enterpriseBase1 == null) {
waterEle.setWaterEleId(CommonUtil.getSysRef());
waterEle.setEnterpriseId(CommonUtil.getSysRef());
waterEle.setStatus(SysData.STATUS_NORMAL);
waterEle.setOperateTime(DateUtil.getDateTime());
int i = waterEleMapper.insertSelective(waterEle);
if (i == 1)
return new ResponseObj<Boolean>(true, RetCode.SUCCESS);
return new ResponseObj<>(false, RetCode.FAIL);
}
return new ResponseObj<>(false, RetCode.FAIL);
}
第四种方案：使用@Param标注
Dao层的函数方法
User selectUser(@Param(“userName”)String name,@Param(“userArea”)String area);
对应的Mapper.xml
<select id=" selectUser" resultMap="BaseResultMap">
SELECT
*
FROM
user_user_t
WHERE
user_name = #{userName，jdbcType=VARCHAR}
AND user_area = #{userArea,jdbcType=VARCHAR}
</select>
个人觉得这种方法比较好，能让开发者看到dao层方法就知道该传什么样的参数，比较直观，个人推荐用此种方案。
完整示例的Dao层接口
@Mapper
public interface OverViewMapper {
int deleteByPrimaryKey(String enterpriseId);
int insert(OverView record);
int insertSelective(OverView record);
OverView selectByPrimaryKey(String enterpriseId);
int updateByPrimaryKeySelective(OverView record);
int updateByPrimaryKey(OverView record);
//
List<Map<String, Object>> list(@Param("extraSql") String extraSql);
List<Map<String, Object>> detail(@Param("enterpriseId") String enterpriseId);
List<DynaTableField> tableName(@Param("dynaKey") String dynaKey);
List<LinkedHashMap<String, Object>> overViewDetail(@Param("startTime") String startTime,
@Param("endTime") String endTime,
@Param("dynaKey") String dynaKey,
@Param("tableName") String tableName);
}
2018.7.2改
对于第四种方案，不管参数name/area是不是对象中的属性，都要加@Param("xx")才能有用！！否则报错。是对象中的属性，那么对于传入参数Map<>和Object是有用的。
