我正在用springboot建立客户数据库，其中包含所有crud操作、分页、排序和搜索功能。因为我是网络开发的新手，所以我关注了两个youtube教程。为了实现积垢操作的模态，我遵循以下步骤：

为了实现分页和排序，我遵循以下步骤：

而且每个想法都太好了！但是。。。
实现排序后，我的情态动词停止工作。单击列的标题后，url将获得排序字段和排序顺序的参数，但modals将不起作用。当我在url中没有参数时，它就工作了。我将不能使用模态后排序和后来当我实现搜索。我相信情态动词是非常用户友好的，我真的想要他们。但我不知道如何处理这个问题，如果你能帮助我，我将非常高兴和感激。

用于modals的javascript main.js：

$(document).ready(function(){
    $('#nBtn, .table #eBtn').on('click', function(event){
        event.preventDefault();
        var href = $(this).attr('href');
        var text = $(this).text();
        var date = new Date();
        if(text == 'Edit')
        {
            $.get(href, function(customerDTO, status){
            $('.myModalFormEdit #idCustomer').val(customerDTO.idCustomer);
            $('.myModalFormEdit #paypalUsername').val(customerDTO.paypalUsername);

    @Autowired
    ICustomerRepository customerRepository;

    @Override
    public void saveCustomer(CustomerDTO customerDTO) throws Exception
    {
        customerRepository.save(customerDTO);

    }

    @Override
    public List<CustomerDTO> getAllCustomers() throws Exception
    {
        return customerRepository.findAll();
    }

    @Override
    public CustomerDTO getCustomerById(int id)
    {
        Optional<CustomerDTO> optional = customerRepository.findById(id);
        CustomerDTO customerDTO = null;

        if (optional.isPresent())
        {
            customerDTO = optional.get();
        }
        else
        {
            throw new RuntimeException("Customer not found for id: " + id);
        }

        return customerDTO;

    }

    @Override
    public void deleteCustomer(int id)
    {
        customerRepository.deleteById(id);

    }

    @Override
    public Page<CustomerDTO> findPaginated(int pageNumber, int pageSize, String sortField, String sortDirection)
    {
        Sort sort = sortDirection.equalsIgnoreCase(Sort.Direction.ASC.name()) ? Sort.by(sortField).ascending() :
            Sort.by(sortField).descending();
        Pageable pageable = PageRequest.of(pageNumber - 1, pageSize, sort);
        return this.customerRepository.findAll(pageable);
    }

}

我有一个服务类，但在本例中它只是将参数传递给dao对象。对于crud操作，我的接口customerrepository扩展了jparepository。
