Question

将列表传递给MyBatis。我们可以将多个输入传递给IN用于SELECT语句，如下所述。请纠正我

dao interface:

public List<Integer> getObjects(List<Test> testList)


Mybatis :
<select id="getObjects" resultType = "Integer">
 SELECT KEY FROM TABLEA WHERE number IN(<foreach collection="TEST" 
  index="index" item="item" separator=", ">
  #{number}
</foreach>)

Answer 1

以下代码可行：

<select id="getObjects" resultType = "Integer">
 SELECT KEY FROM TABLEA WHERE number IN
 (<foreach collection="list" 
   index="index" item="item" separator=", ">
   #{item.number}
   </foreach>)
</select>

MyBatis：在IN的Select语句中使用List <object>中的Multipe输入
