ibatis batch submit sql

My project's persistence layer uses ibatis:

 

After the interface of my project is called, it returns a jsonArray string, and then replaces it with a List<Object> object. The insert is to insert the loop List<Object> object in batches. The code diagram is as follows:

 

Action layer:

@RequestMapping(value = "/test.htm", method = RequestMethod.POST)
    public String init(HttpServletRequest request ) throws IOException {

        //Receive interface return data
        Map<String, String> map = new HashMap<String, String>();
        Enumeration<?> fields = request.getParameterNames();

        while(fields.hasMoreElements())
        {
            String field = (String) fields.nextElement();
            String[] values = request.getParameterValues(field);
            if (values.length > 1)
                map.put(field, values.toString());
            else
map.put(field, values[0]);
        }
        System.out.println(map.get("jsonArray"));


        //自定义测试数据
//        String arrayStr ="[{\"amount\":\"9.83\",\"fundCategory\":\"A\",\"postStaus\":\"I\",\"fundChannelCode\":\"WEIXINPAY11601\",\"instOrder\":\"FI116011001082400080288\",\"happenDate\":\"20170824\",\"remarks\":\"20170824扣除入款手续费9.83元\",\"creater\":\"Arvin\",\"createTime\":\"20170907\",\"auditor\":\"\",\"auditorTime\":\"\",\"deleteFlag\":\"N\"},{\"amount\":\"15.77\",\"fundCategory\":\"A\",\"postStaus\":\"I\",\"fundChannelCode\":\"WEIXINPAY11601\",\"instOrder\":\"FI116011001082400080301\",\"happenDate\":\"20170824\",\"remarks\":\"20170824扣除入款手续费15.77元\",\"creater\":\"Arvin\",\"createTime\":\"20170907\",\"auditor\":\"\",\"auditorTime\":\"\",\"deleteFlag\":\"N\"}]";
if(map.get("jsonArray")!=null && map.get("jsonArray"if(map.get("jsonArray")!=null && map.get("jsonArray"if(map.get("jsonArray")!=null && map.get("jsonArray").length()>0){
            String arrayStr = map.get( "jsonArray" );
             logger .info( "The interface returns jsonArray: " +arrayStr);
            List<PostAccountVO> postAccountVOList = new ArrayList<PostAccountVO>();

            List<Map<String,String>> listObjectSec = JSONArray.parseObject(arrayStr,List.class);
            Map<String,String> mapList = new HashMap<String, String>();
            for(int i=0;i<listObjectSec.size();i++){
                mapList = listObjectSec.get(i);
                JSONObject jsonObject = JSONObject.fromObject(mapList);
                PostAccountVO postAccountVO = (PostAccountVO) JSONObject. toBean (jsonObject, PostAccountVO. class );
                postAccountVOList.add (postAccountVO);
            }
            System.out.println( postAccountVOList.size());

            //After the received data is transferred to the list object, it is stored in the database
            GlideSyncResult result = postAccountFacade.getBankHandlingCharge(postAccountVOList);

        }else{System.out 
            .println ( "The interface is empty!" );
             logger .info( "The interface is empty!" );
        }

        return "";
    }

 

service layer:

public GlideSyncResult getBankHandlingCharge(List<PostAccountVO> vo);

 

Service impl implementation layer:

My situation is: the service layer entity class is VO, the dao layer entity class is DO, so I want to call the dao layer method, and I want to convert the object to the dao layer object

(VO and DO entity classes are the same, but this project is based on this format. I also built VO and DO entity classes respectively. You should probably build an entity class, so there is no need to convert)

 

@Override
public GlideSyncResult getBankHandlingCharge(List<PostAccountVO> vo) {



    List<PostAccountInfoDO> infoDOList = new ArrayList<PostAccountInfoDO>();
    int status=0;

    if(vo!=null && vo.size()>0){

            for(int i=0;i<vo.size();i++){
                PostAccountInfoDO infoDO = new PostAccountInfoDO ();
                    infoDO.setAccountSeqNo ( postAccountInfoDAO .getAccountNo ());
                    infoDO.setAmount(vo.get(i).getAmount());
                    infoDO.setFundCategory(vo.get(i).getFundCategory());
                    infoDO.setPostStaus(vo.get(i).getPostStaus());
                    infoDO.setFundChannelCode(vo.get(i).getFundChannelCode());
                    infoDO.setHappenDate(vo.get(i).getHappenDate());
                    infoDO.setRemarks(vo.get(i).getRemarks());
                    infoDO.setCreater(vo.get(i).getCreater());
                    infoDO.setCreateTime(vo.get(i).getCreateTime());
                    infoDO.setAuditor(vo.get(i).getCreater());
                    infoDO.setAuditorTime(vo.get(i).getCreateTime());
                    infoDO.setDeleteFlag (vo.get (s) .getDeleteFlag ());
                    infoDO.setInstOrder(vo.get(i).getInstOrder());

                    infoDOList.add(infoDO);
            }

        status = postAccountInfoDAO.insert(infoDOList);
    }

    if (status> 0) {
        return new GlideSyncResult(GlideSyncResultCode.SUCCESS);
    } else {
        return new GlideSyncResult(GlideSyncResultCode.FAILED);
    }
}

 

dao layers:

public int insert(List<PostAccountInfoDO> infoDOList ) throws DataAccessException;

 

Dao impl implementation layer:

@Override
public int insert(List<PostAccountInfoDO> infoDOList ) throws DataAccessException {
    if(infoDOList==null){
        throw new IllegalArgumentException("Can't insert a null data object into db.");
    }
    Integer nums =  (Integer)getSqlMapClientTemplate().insert("MS-POST-ACCOUNT-INFO-INSERT", infoDOList);

    if(nums==null){
        return 1;
    }

    return 0;
}

 

mapper.xml:

<insert id="MS-POST-ACCOUNT-INFO-INSERT" parameterClass="java.util.List">
      insert all
      <iterate  conjunction="" >
         <![CDATA[
         into TB_POST_ACCOUNT_INFO
         (ACCOUNT_SEQ_NO,AMOUNT,FUND_CATEGORY,POST_STAUS,FUND_CHANNEL_CODE,HAPPEN_DATE,REMARKS,CREATER,CREATE_TIME,AUDITOR,AUDITOR_TIME,DELETE_FLAG,INST_ORDER)
         values
            (#infoDOList[].accountSeqNo#,#infoDOList[].amount#,#infoDOList[].fundCategory#,#infoDOList[].postStaus#,
            #infoDOList[].fundChannelCode#,#infoDOList[].happenDate#,#infoDOList[].remarks#,#infoDOList[].creater#,
#infoDOList[].createTime#,#infoDOList[].auditor#,#infoDOList[].auditorTime#,#infoDOList[].deleteFlag#,
#infoDOList[].instOrder#)
        ]]>
      </iterate>
      select 1 from dual
   </insert>

 

Notice:

If you add data, if there are automatically generated parameters, for example:

<select id="ACCOUNT-INFO-NO" resultClass="String">
   <![CDATA[
       select seq_post_account_info.nextval from dual
   ]]>
</select>

 

It is recommended to write a separate SQL query, and then insert the value into the object after finding it, as shown in the following figure:

 

 

The method is rather stupid. . .

Moreover, the batch submission quantity of this method should be less than one thousand (size() < 1000)

 

If you find a better way, please let me know and I will learn it.
