Question

前言：我在Tomcat或Tomee服务器上没有这个问题。

我试图通过ajax执行一个简单的Get请求，当请求到达服务器时，它会执行错误的方法。

JS档案

function CustomerPoints() {
        this.initializeListeners = function () {
            $("#storeSelect").change(function (event) {
                event.preventDefault();
                customerPoints.callAjax(contextPath + "/loyaltyPoints/customerPoints?getPoints&id=" + $("#storeSelect").val());
            });

        this.callAjax = function (url, value) {
            // generated url = http://localhost:9080/TLC/loyaltyPoints/customerPoints?getPoints&id=3778
            var cardNumber = $("#customerNumber");
            var alternateId = $("#alternateId");
            $
                .ajax(
                url,
                {
                    type: "GET",
                    data: value,
                    beforeSend: function (req) {
                        $("#modalErrorDiv").empty();
                        req.setRequestHeader("Accept",
                            "text/html;type=ajax");
                        req.setRequestHeader($(
                            "meta[name='_csrf_header']").attr(
                            "content"), $("meta[name='_csrf']")
                            .attr("content"));
                    },
                    complete: function (jqXHR) {
                        $("#customerNumber").replaceWith(cardNumber);
                        $("#alternateId").replaceWith(alternateId);
                        customerPoints.initializeListeners();
                    },
                    success: function (data, textStatus, jqXHR) {
                        $("#content").replaceWith(data);
                    },
                    error: function (jqXHR, textStatus, errorThrown) {
                        $('html,body').animate({
                            scrollTop: $('body').offset().top
                        }, 'slow');
                        $("#modalErrorDiv").empty();
                        $("#modalErrorDiv")
                            .append("<ul ><li class='error'>An error has occured. Please contact support.</li></ul>");
                    }
                });
        };

控制器

@Controller
public class CustomerPointsController
{
    private static final String HTML_PAGE          = "loyaltyPoints/customerPoints";
    private static final String REQUESTMAPPING     = "/" + HTML_PAGE;
    private static final String APPLYPOINTSMAPPING = "loyaltyPoints/applyPoints :: #content";
    private static final String CONTENT            = HTML_PAGE + " :: #content";

    /**
     * @param model
     * @return
     */
    @RequestMapping(value = REQUESTMAPPING)
    public String maintainCustomerPoints(Model model)
    {
        // this is the method that is called everytime
        return HTML_PAGE;
    }

    /**
     * @param id
     * @param model
     * @returns the valid customer points for this store, default followed by promotion points
     * when a user picks a store from the drop down.
     */
    @RequestMapping(value = REQUESTMAPPING, method = RequestMethod.GET, params = {
            "getPoints"})
    public String getPoints(@RequestParam(value = "id") String id, Model model)
    {
        // this is the method that never gets called
        return CONTENT;
    }
}

注意我还从页面脚本中获取了生成的URL并粘贴到我的浏览器中以执行。它只执行maintainCustomerPoints。

Answer 1

根据documentation @RequestMapping，如果params形式中有{"myParam"}，则假定此参数必须存在于请求中且可能具有任何值。< / p>

因此，网址的安全形式应包含getPoints的任何值，例如customerPoints?getPoints=anyValueHere。

当没有值存在时，request.getParameter()方法可能会为Tomcat返回不同的值。对于Liberty，如果null没有=，则会customerPoints?getPoints，non null和= customerPoints?getPoints=

Liberty Profile服务器根据请求执行错误的功能
