Mybatis-plus中的condition条件

Posted 2020-11-22 King-D

    @Test
    public void testCondition() {
        String name = "王";
        String email = "";
        condition(name, email);
    }


    private void condition(String name, String email) {
        QueryWrapper<User> wrapper = new QueryWrapper<>();
        //需要六行,太麻烦
//        if(StringUtils.isNotBlank(name)){
//            wrapper.like("name",name);
//        }
//        if(StringUtils.isNotBlank(name)){
//            wrapper.like("name",name);
//        }
        wrapper.like(StringUtils.isNotBlank("name"), "name", name)
                .like(StringUtils.isNotBlank("email"), "email", email);
        List<User> users = userMapper.selectList(wrapper);
        for (User user : users) {
            System.out.println(user.toString());
        }
    }

使用这种condition条件可以让语句看起来更加简洁一下
