ibatis batch transaction submission

with iabtis 

<iterate conjunction="">

 Batch submission, the disadvantage is that the number of submissions is limited, size<1000;

Batch submission:  http://fengxiaoshuang429201406254717.iteye.com/blog/2392798

 

 

For a large amount of data, use transaction submission:

What I set here is, insert one by one, when it is full 5000, the transaction is submitted;

 

If 10,000 pieces of data come, things will be submitted in two batches;

 

Service impl implementation layer:

/** 5000 submissions once */
    public static final int        BATCH_SIZE           = 5000;

    /** Transaction template */
    protected TransactionTemplate transactionTemplate;

    /** sql execution template */
    protected SqlMapClientTemplate sqlMapClientTemplate = new SqlMapClientTemplate();
    private SqlMapClient sqlMapClient;
	
	 public SqlMapClientTemplate getSqlMapClientTemplate() {
        return sqlMapClientTemplate;
    }

    public void setSqlMapClientTemplate(SqlMapClientTemplate sqlMapClientTemplate) {
        this.sqlMapClientTemplate = sqlMapClientTemplate;
    }

    public SqlMapClient getSqlMapClient() {
        return sqlMapClient;
    }

    public void setSqlMapClient(SqlMapClient sqlMapClient) {
        this.sqlMapClient = sqlMapClient;
        this.sqlMapClientTemplate.setSqlMapClient(sqlMapClient);
    }

    public void setTransactionTemplate(TransactionTemplate transactionTemplate) {
        this.transactionTemplate = transactionTemplate;
    }
	
	
	 @Override
    public void getBankHandlingCharge(final List<PostAccountVO> vo) {

        sqlMapClientTemplate.execute(new SqlMapClientCallback() {
            public Object doInSqlMapClient(SqlMapExecutor executor) throws SQLException {
                executor.startBatch();
                int indexInBatch = 0;
                List<PostAccountInfoDO> infoDOList = new LinkedList<PostAccountInfoDO>();
                for (PostAccountVO poa: vo) {
                    PostAccountInfoDO infoDO = new PostAccountInfoDO ();
                    infoDO.setAmount(poa.getAmount());
                    infoDO.setFundCategory(poa.getFundCategory());
                    infoDO.setPostStaus(poa.getPostStaus());
                    infoDO.setFundChannelCode(poa.getFundChannelCode());
                    infoDO.setHappenDate (poa.getHappenDate ());
                    infoDO.setRemarks(poa.getRemarks());
                    infoDO.setCreater(poa.getCreater());
                    infoDO.setCreateTime(poa.getCreateTime());
                    infoDO.setAuditor(poa.getCreater());
                    infoDO.setAuditorTime(poa.getCreateTime());
                    infoDO.setDeleteFlag(poa.getDeleteFlag());
                    infoDO.setInstOrder(poa.getInstOrder());
                    infoDOList.add(infoDO);
                }

                for (PostAccountInfoDO postAccountInfoDO: infoDOList) {
                    if (indexInBatch > BATCH_SIZE) {//5000 items are processed as a batch. If it exceeds 5000, it will be used as the next batch.
                        executor.executeBatch();
                        executor.startBatch();
                        indexInBatch = 0;
                    }
                    executor.insert("MS-POST-ACCOUNT-INFO-INSERT", postAccountInfoDO);

                    indexInBatch++;

            }
                return executor.executeBatch();
            }
    });
    }

 

 

The insert method is not the implementation method of the dao layer, but the insert method in the executor, which means that the method with id=" MS-POST-ACCOUNT-INFO-INSERT " in the mapping.xml file is directly accessed here ;

 

 mapping.xml layer:

<insert id="MS-POST-ACCOUNT-INFO-INSERT">
   <selectKey resultClass="java.lang.String" keyProperty="accountSeqNo">
      <![CDATA[
       select seq_post_account_info.nextval from dual
   ]]>
   </selectKey>
   <![CDATA[
       insert into TB_POST_TABLE(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
       ( #accountSeqNo#, #amount#, #fundCategory#, #postStaus#, #fundChannelCode#, #happenDate#, #remarks#, #creater#, #createTime#, #auditor#, #auditorTime#, #deleteFlag#, #instOrder#)
   ]]>
</insert>

 

 

 

 

 

Transaction commit failed rollback:

 I throw an exception (as shown below) before the transaction is submitted, the data is not added to the database, there should be a rollback mechanism in it
