mybatis 調用mysql存儲過程 帶輸出輸入參數

存儲過程都是一樣的，只是根據自己的喜好，可以用MAP或者JAVABEAN傳遞參數。

CREATE DEFINER=`root`@`localhost` PROCEDURE `selectCount`(
    IN pcsId int,
    IN drId int,
    IN partnerId int,
    IN customerId int,
    OUT pcsCount int,
    OUT drCount int

)
BEGIN

    select count(md.id) into @pcsC from mdm_device md
left join mdm_device_security mds on mds.device_id = md.id
where mds.device_rooted = pcsId
and md.partner_id = partnerId and md.customer_id = customerId;
set pcsCount = @pcsC;


select count(md.id) into @drC from mdm_device md
where md.managed_status = drId and  DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(md.un_manage_date)
and md.partner_id = partnerId and md.customer_id = customerId;
set drCount = @drC;



END

 

 

1.java調用傳入MAP。獲取通過MAP獲取。

1.1 mapper文件寫法

<parameterMap type="map" id="homeVO">
   <parameter property="pcsId" jdbcType="INTEGER" mode="IN"/>
   <parameter property="drId" jdbcType="INTEGER" mode="IN"/>
   <parameter property="partnerId" jdbcType="INTEGER" mode="IN"/>
   <parameter property="customerId" jdbcType="INTEGER" mode="IN"/>
   <parameter property="pcsCount" jdbcType="INTEGER" mode="OUT"/>
   <parameter property="drCount" jdbcType="INTEGER" mode="OUT"/>
 </parameterMap>
<select id="selectForHome" parameterMap="homeVO"
      statementType="CALLABLE">
      {call selectCount(
        ?,?,?,?,?,?
      )}
  </select>

 1.2 java調用寫法

@Override
    public StringselectHomeCount(HomeVO home) throws Exception {
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("pscId", 0);
        map.put("drId", 1);
        map.put("partnerId", 25);
        map.put("customerId", 50);
        map.put("isolation", 1);
        selectOne("Mapper.selectForHome", map);
        System.out.println(map.get("pcsCount"));

            return map.get("drCount");
    }

 

 

2.java調用傳入javaBean。返回值通過javaBean屬性獲取

2.1 通過javabean傳遞參數  mapper寫法

<parameterMap type="com.polysaas.mdm.device.entity.HomeVO" id="home">
     <parameter property="pcsId" jdbcType="INTEGER" mode="IN"/>
   <parameter property="drId" jdbcType="INTEGER" mode="IN"/>
   <parameter property="partnerId" jdbcType="INTEGER" mode="IN"/>
   <parameter property="customerId" jdbcType="INTEGER" mode="IN"/>
   <parameter property="pcsCount" jdbcType="INTEGER" mode="OUT"/>
   <parameter property="drCount" jdbcType="INTEGER" mode="OUT"/>
 </parameterMap>

 javaBean可以通過兩種來進行映射

<resultMap type="com.polysaas.mdm.device.entity.HomeVO" id="home">
        <result column="partnerId" property="partnerId" jdbcType="INTEGER"/>
        <result column="customerId" property="customerId" jdbcType="INTEGER" />
        <result column="pcsId" property="pcsId" jdbcType="INTEGER" />
        <result column="drId" property="drId" jdbcType="INTEGER" />
        <result column="pcsCount" property="pcsCount" jdbcType="INTEGER" />
        <result column="drCount" property="drCount" jdbcType="INTEGER" />
  </resultMap>
  <select id="selectForHome2" parameterType="com.polysaas.mdm.device.entity.HomeVO"
      statementType="CALLABLE">
      {call selectCount(
        #{pcsId,jdbcType=INTEGER, mode=IN},
        #{drId, jdbcType=INTEGER,mode=IN},
        #{partnerId, jdbcType=INTEGER,mode=IN},
        #{customerId, jdbcType=INTEGER,mode=IN},
        #{pcsCount, jdbcType=INTEGER,mode=OUT},
        #{drCount, jdbcType=INTEGER,mode=OUT}
      )}
  </select>

 2.2 通過javabean傳遞參數  java調用寫法

@Override
public HomeVO selectHomeCount(HomeVO home) throws Exception {
HomeVO vo = new HomeVO();
vo.setPcsId(0);
vo.setDrId(0);
vo.setPartnerId(25);
vo.setCustomerId(50);
vo.setPcsCount(0);
vo.setDrCount(0);
selectOne("com.polysaas.mdm.device.mapper.MdmDeviceMapper.selectForHome2", vo);
return vo;
}

 

 

遇到異常很多。。記得的寫下

1.通過javaBean的時候，#{pcsId, mode=IN, javaType=INTEGER},javaType這個屬性是必須的。

2.使用javaBean傳遞。輸出參數不需要初始值。個人喜好並建議使用javaBean，因為定義更清晰，封裝性。

3.map可以用占位符問號，javaBean不可以。  會有異常 No value specified for parameter 1

4.   說不認識某個參數。。可能是沒有創建存儲過程，這個發生在多個庫的時候

5.  read Only  這個可能是事務控制只讀。。我是因為存儲過程有set 語句，而方法叫做selectAaaa()。
