mybatis由於簡單易用性得到大家的認可和使用

但是在批量更新操作中，網上介紹的貌似不全，正好今天做個記錄，大家一起進步

在實際項目開發過程中，常有這樣的需求：根據ids更新表的某一個字段值，這時的sql語句是：

 

1.  
   public interface IStaffDao {
2.  
   void batchUpdate(@Param("list") List<Long> list);
3.  
   }

 

 

1.  
   <select id="getStaffsByIds" resultMap="staff_Mapper">
2.  
   update staff set status = 0 where id in
3.  
   <foreach collection="list" item="item" index="index" open="(" separator="," close=")" >
4.  
   #{item}
5.  
   </foreach>
6.  
   ORDER BY id
7.  
   </select>

還有一種情況：根據ids更新表的多個值，並且每個id對應的值也不一樣，這時上述語句已經滿足不了需求，需要另一種批量更新sql語句

 

 

1.  
   public interface IStaffDao {
2.  
   void batchUpdate(@Param("list") List<Staff> list);
3.  
   }

 

 

1.  
   <update id="batchUpdate" parameterType="java.util.List" >
2.  
   <foreach collection="list" item="item" index="index" separator=";">
3.  
   UPDATE staff set count = #{item.count} , code = #{item.code} , invalid_time = #{item.time} WHERE id = #{item.id}
4.  
   </foreach>
5.  
   </update>

由於這種批量更新是一次執行多個update語句，所以mybatis需要額外的配置：

 

在spring.datasource.url后加上allowMultiQueries=true
如：jdbc:mysql://10.10.20.36:3306/test?allowMultiQueries=true

否則，在執行sql語句時，會報下面的錯誤

 

1.
