关于mybatis的批量删除操作

批量删除功能是实现

Mapper.xml文件写法

<!-- 批量删除用户 --> 

  <delete
id =
"deleteUserWithBatch"parameterType
="java.util.List"> 

    <![CDATA[ 

       delete from plat_cust where cid in 

    ]]> 

    <foreach
collection="list"
item =
"model" open="("
separator=","
close=")">
    #{ model} 
    </foreach> 

</delete>

Mapper中的写法

/**
     * 批量删除用户
     * @param ids
     * @return
     */
intdeleteUserWithBatch(Listlist);

 

serviceImpl中的写法

/*
          * 批量删除用户
          * @param
          * @return
          */
         @Override
         publicinttxDeleteUserWithBatch(List<String>
ids)throwsException {
                 
                  intcount =
custMapper.deleteUserWithBatch(ids);
              returncount;

}

 

Action中的写法

//批量删除用户
   
    publicvoiddeleteBatch() {
    try {
              String[]
idsList =
po.getIdStringList().split(",");
              Listids =
null;
             
              if (idsList.length>0)
{
                       List<String>
idsList1=Arrays.asList(idsList);
                                  
ids= newArrayList(idsList
4000
1);
                          }
              System.out.println("=============="
+ ids);
                          custService.txDeleteUserWithBatch(ids);
                          this.getMap().put(Constants.RET_CODE,
"0000");
                          this.getMap().put(Constants.RET_MSG,
"成功");
                  } catch (Exceptione)
{
                          e.printStackTrace();
                          this.getMap().put(Constants.RET_CODE,
"9999");
                          this.getMap().put(Constants.RET_MSG,
"查询异常");
                          this.returnMap2Json(map);
                  }
    }
