mybatis plus中QueryWrapper的查询

@Test
    public void squery() {
        //创建QueryWrapper 对象
        QueryWrapper<User> queryWrapper = new QueryWrapper<>();

        //ge gt le lt: 大于等于 大于 小于等于 小于
        queryWrapper.ge("age",29);
        List<User> users = userMapper.selectList(queryWrapper);
        System.out.println(users);
        
        //eq ne  等于 不等于

        //between 介于查询
        queryWrapper.between("age",28,30);
        List<User> users1 = userMapper.selectList(queryWrapper);
        System.out.println(users1);
        
        //模糊查询
        queryWrapper.like("nam","l");
        queryWrapper.select("id","nam");
        List<User> users2 = userMapper.selectList(queryWrapper);
        System.out.println(users2);
        
        // orderByDesc 降序查找
        queryWrapper.orderByDesc;
        
        //last 在sql语句后面拼接
        queryWrapper.last("limit 1");

    }
