TbUserMapper.xml

(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");
>        }
>     }
