I am having liferay portlet and I need to heavily depend upon the AJAX calls. So I need to make multiple calls to serveResource method. One way to do the same is that I can pass a parameter with the URL and then differentiate the request according to that parameter.

But in my case I have to call serveResource so many times due to which the method will be difficult to maintain. Is there any framework to do so? Using which the code becomes maintainable.

使用 Spring MVC 框架并根据控制器中的业务逻辑/用户操作调用不同的方法，

在jsp中尝试以下代码

<portlet:resourceURL var="loadContents" id="loadContents"></portlet:resourceURL>
<portlet:resourceURL var="loadCategories" id="loadCategories"></portlet:resourceURL>

jsp中的ajax调用

AUI().ready(
        function(A) {            
            A.use('aui-io-request', 
                    function(aui) {
                    A.io.request("<%=loadContents%>", {
                        autoLoad : false,
                        cache : false,
                        dataType : 'json',
                        data:{},
                        method:'POST',
                        on : {
                            success : function(event, id, xhr) {
                                var response = this.get('responseData');
                                 // add logic here after response
                            }
                        }
                    }).start();
                });
        });

在控制器/ java 类中

    @ResourceMapping("loadCategories")
    public void loadCategories(final ResourceRequest resourceRequest, final ResourceResponse resourceResponse)
    {
         // your business logic goes here
    }

    @ResourceMapping("loadContents")
    public void loadContents(final ResourceRequest resourceRequest, final ResourceResponse resourceResponse)
    {
         // your business logic goes here
    }

希望上面的代码片段能帮助你，你得到你想要的！！！

在此添加更多。我们不能使用serveResource像这样的方法processAction。单个liferay portlet（不是spring mvc portlet）中可以有多个processAction，而在它的情况下serveReource它将是单个的。

serveResource主要用于ajax调用。我们可以serveResource通过resource Id区分调用，在方法中处理多个ajax请求。

resourceRequest.getResourceID()将返回我们在 jsp 中使用以下代码定义的 Id。

<portlet:resourceURL var="demoUrl" id="demoUrl"></portlet:resourceURL>
