Spring 与 mybatis整合---事务管理

MyBatis与Spring整合前后事务管理有所区别

整合前：通过

　　session = sessionFactory.openSession(true);　　//或者是false

设置事务是否自动提交；

整合后，在这样写就不起作用了，无论设置为true还是false  都会自动提交事务；

如果想设置事务非自动提交有以下几种方案：

　　① 创建session之后，手动拿到connection，设置事务非自动提交

　　session.getConnection().setAutoCommit(false);

　　② 通过spring管理事务

    @Test
    /**
     * 测试插入数据，同时测试手动提交事务
     */
    public void test_insert() {
        System.out.println("==============插入数据==================");
        //开启事务
        DefaultTransactionDefinition definition = new DefaultTransactionDefinition();
        DataSourceTransactionManager transactionManager = (DataSourceTransactionManager) DaoApplicationContext
                .getInstance().getBean("txManager");
        TransactionStatus transactionStatus = (TransactionStatus) transactionManager
                .getTransaction(definition);

        Fh_fullnote order = new Fh_fullnote();
        order.setHf_serialid("HF100120160829155555012507");
        order.setHf_orderid("OD100120160829155555012507");
        order.setCharge_phone("18201304217");
        order.setCharge_money(50D);
        int insertRet = fh_fullnoteDao.insert(order);

        //提交事务
        transactionManager.commit(transactionStatus);
        System.out.println("插入数据返回值：" + insertRet);
    }

　　

　　③ 注解式事务

　　首先对Dao层做一个详细的解析

　　Dao层应用上下文

package ctp.demo.dao.fh.dao;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class DaoApplicationContext {
    private static ApplicationContext ctx=null;

    public static ApplicationContext getCtx() {
        return ctx;
    }
    public static void setCtx(ApplicationContext ctx) {
        DaoApplicationContext.ctx = ctx;
    }

    public static ApplicationContext getInstance(){
        if(ctx == null){
            ctx=new ClassPathXmlApplicationContext("applicationContext-Dao.xml");
        }
        return ctx;
    }
}

DaoApplicationContext.java

　　Dao数据模型

package ctp.demo.dao.fh.vo;

import java.util.Date;

public class Fh_fullnote {
    String hf_serialid ;    //流水号
    String hf_orderid ;        //订单号

applicationContext-Dao.xml

　　下面看Service层：

package ctp.demo.service.fh;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;

import ctp.demo.dao.fh.dao.Fh_fullnote_dao;
import ctp.demo.dao.fh.vo.Fh_fullnote;

@Component("fh_fullnoteService")
@Transactional
public class Fh_fullnoteService {

    @Autowired
    Fh_fullnote_dao fh_fullnoteDao;

    @Transactional(rollbackFor={Exception.class, RuntimeException.class})
    public int addOrder(Fh_fullnote order){
        try {
            int insertRet = fh_fullnoteDao.insert(order);
            System.out.println("下单结果：" + insertRet);
            return 0;
        } catch (Exception e) {
            // TODO: handle exception
            return -1;
        }
    }

    public Fh_fullnote_dao getFh_fullnoteDao() {
        return fh_fullnoteDao;
    }
    public void setFh_fullnoteDao(Fh_fullnote_dao fh_fullnoteDao) {
        this.fh_fullnoteDao = fh_fullnoteDao;
    }
}

　　测试代码：　　

package ctp.demo.service.fh;

import static org.junit.Assert.*;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.TransactionStatus;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.transaction.support.DefaultTransactionDefinition;

import ctp.demo.dao.fh.dao.DaoApplicationContext;
import ctp.demo.dao.fh.vo.Fh_fullnote;

public class Test_Fh_fullnoteService {

    @Test
    public void test() {
        System.out.println("===============下单开始================");

        Fh_fullnote order = new Fh_fullnote();
        order.setHf_serialid("HF100120160829155555012510");
        order.setHf_orderid("OD100120160829155555012510");
        order.setCharge_phone("18201304217");
        order.setCharge_money(50D);
        //关于Dao层的配置文件，需要在service层读取，然后将上下文注入到Dao里面
        //否则的话 @Transactional注解是不生效的
        String[] configeRations = new String[]{"applicationContext-Service.xml","applicationContext-Dao.xml"};
        ApplicationContext ctx=new ClassPathXmlApplicationContext(configeRations);
        DaoApplicationContext.setCtx(ctx);
        Fh_fullnoteService fullnote_service = (Fh_fullnoteService)ctx.getBean("fh_fullnoteService");
        fullnote_service.addOrder(order);
        System.out.println();
    }

}

　　通过断点调试，发现跳出函数之前，是不会提交的，说明注解事务生效。

　　需要注意的是，Dao层应用的上下文应该与Service应用的上下文一致，那么Dao层的配置文件就应该在Service层读取，然后将上下文注入到Dao层中。
