麻烦的Ajax / json和spring mvc

Question

- edit-- 发生的事情是我可以看到控制台/ sout项目，我从数据库中获取对象，当前我得到500内部服务器错误，每个修复我尝试了一个错误消失（400已经很受欢迎）和然后我得到另一个，我解决它，然后我得到另一个。

我正在获取数据，但是通话仍然失败，我无法对信息做任何事情，我看到了这些数据，但我无法弄清楚如何正确捕获它。

我想要做的是搜索客户，如果该客户存在则在下一页表单中填充该信息，如果不是仅将搜索条件插入下一页表单中的相应字段。

这是javascript，我无法弄清楚加载函数，因为它似乎没有正常工作（不确定如何正确捕获数据）。

$('#search-customer').click(function (event) {
        var testdata = document.getElementById('searchCustomerForm');
        // var isvalid = checkForm(form);
//        if (isvalid === false) {
//            event.preventDefault();
//            alert('is valid===false');
//        } else {
        alert('hit search customer ajaxcall');
        $.ajax({
            type: 'GET',
            url: 'customerLookup/?firstName=' + $('#search_first_Name').val() + '&lastName=' + $('#search_last_Name').val() + '&compId=' + companyId,
            data: JSON.stringify({
                firstName: $('#search-first_name').val(),
                lastName: $('#search-last_name').val(),
                //  dob: $('#search_birthdate').val(),
                // license: $('#search_license_number').val()
                //  dob: $('#search_birthdate').val(),
                compId: $('#search_companyId').val(companyId)
            }),
            headers: {
                'Accept': 'application/json',
                'Content-Type': 'application/json'
            },
            'dataType': 'json'
        }).done(function (data, status) {
            if (data !== null) {
                window.location = "/app/ticketStepOneTwoAddCustomer";
                loadCustomerInputForm(data, status);
                alert('customer found, moving to confirm');
            }
            else if (data === null) {
                window.location = "/app/ticketStepOneTwoAddCustomer";
                addSearchInfoToInputCustomerForm();
                alert('no customer of that name found, moving to add customer');
            }
        }).fail(function () {
            alert('not a success');
          //  window.location = "/app/ticketStepOneTwoAddCustomer";
        });
    });


function loadinputcustomerform(data, status) {
    alert('hit loadinputcustomerform function');
    console.log(cust.customer.getCustomerFirstName());
    console.log(data.customer.getCustomerMiddleName());
    console.log(customer.getCustomerLastName());

这是控制器

@RequestMapping(value = {"/customerLookup"}, method = RequestMethod.GET)
    @ResponseBody
    public Customer getCustomerByCriteria(
            @RequestParam(value = "compId", required = false) int compId,
            @RequestParam(value = "firstName", required = false) String fName,
            @RequestParam(value = "lastName", required = false) String lName) {
        System.out.println("here: " + compId + " -- " + fName);
        Customer cust = customerService.searchCustomer(fName, lName, compId);
        //System.out.println(cust.getCustomerLicense());
      return cust;
    }

在java方面，客户只是一个对象，在DB中，companyID是FK，一切都需要compID，我在想他们应该制作一个客户的hashmap或list但不是我的区域，这就是我所拥有的与...合作。

这是html

我当时认为私有客户属性是一个问题，但我认为公共吸气者和制定者仍然可以使用。
