SSM项目中实现数据批量插入数据库

(一)持久层部分TbUserDao.java

TbUserMapper.xml

(二)逻辑控制层UserService.java接口

实现类UserServiceImpl.java

(三)使用单元测试验证代码

@Test
public void insertTbUserBatch(){
    TbUser tbUser = new TbUser();
    tbUser.setId(8L);
    tbUser.setUsername("8");
    tbUser.setPassword("8");
    tbUser.setPhone("8");
    tbUser.setEmail("8");
    String strdate1="2017-05-17";
    String strdate2="2017-05-28";
    SimpleDateFormat  sdf = new SimpleDateFormat("yyyy-MM-dd");

    try {
        tbUser.setCreated(sdf.parse(strdate1));
        tbUser.setUpdated(sdf.parse(strdate2));
    } catch (ParseException e) {
        e.printStackTrace();
    }

    TbUser tbUser1 = new TbUser();
    tbUser1.setId(7L);
    tbUser1.setUsername("7");
    tbUser1.setPassword("7");
    tbUser1.setPhone("7");
    tbUser1.setEmail("7");
    String strdate11="2018-05-17";
    String strdate21="2018-05-28";
    SimpleDateFormat  sdf1 = new SimpleDateFormat("yyyy-MM-dd");
    try {
        tbUser1.setCreated(sdf1.parse(strdate11));
        tbUser1.setUpdated(sdf1.parse(strdate21));
    } catch (ParseException e) {
        e.printStackTrace();
    }

    List<TbUser> list = new ArrayList<TbUser>();
    list.add(tbUser);
    list.add(tbUser1);
   int result = userService.insertTbUserBatch(list);
   if(result == list.size()){
       System.out.println("批量插入成功");
   }else{
       System.out.println("批量插入失败");
   }
}

验证结果:
