优先使用 LambdaQueryWrapper、LambdaQueryChainWrapper

        // 优先使用 LambdaQueryWrapper、LambdaQueryChainWrapper
        User user = new User();
        QueryWrapper<User> queryWrapper1 = Wrappers.<User>query().like("name", "李");
        QueryWrapper<User> queryWrapper2 = Wrappers.query(user).like("name", "李");

        LambdaQueryWrapper<User> lambdaQueryWrapper1 = Wrappers.<User>lambdaQuery().like(User::getName, "李");
        LambdaQueryWrapper<User> lambdaQueryWrapper2 = Wrappers.lambdaQuery(user).like(User::getName, "李");
        LambdaQueryWrapper<User> lambdaQueryWrapper3 = Wrappers.lambdaQuery(User.class).like(User::getName, "李");

        QueryChainWrapper<User> queryChainWrapper = ChainWrappers.queryChain(User.class).like("name", "李");
        queryChainWrapper.list();
        queryChainWrapper.one();
        queryChainWrapper.count();

        LambdaQueryChainWrapper<User> lambdaQueryChainWrapper = ChainWrappers.lambdaQueryChain(User.class).like(User::getName, "李");
        lambdaQueryChainWrapper.list();
        lambdaQueryChainWrapper.one();
        lambdaQueryChainWrapper.count();
