无法通过Ajax调用

Question

1.Below打Spring MVC的控制器在我的index.jsp Ajax调用

<script type="text/javascript"> 
     $(document).ready(function(){ 
      $('#buttonDemo1').click(function(){ 
       $.ajax({ 
        method: "GET", 
        url: '${pageContext.request.contextPath}/ajax/demo1', 
        success: function(result){ 
         $('#result1').html(result); 
        }, 
          error: function(response){ 
           console.log("error"); 
          } 
       }); 
      }); 
     }); 
    </script> 

2.Below是控制器的代码

@Controller 
    @RequestMapping("/ajax") 
    public class AjaxController { 
    @RequestMapping(method = RequestMethod.GET) 
    public String index() { 
    return "ajax/index"; 
    } 

    @RequestMapping(value="/demo1", method = RequestMethod.GET) 
    @ResponseBody 
    public String demo1() { 
     return "Demo 1"; 
    } 
    } 

3.下面是调度员的代码

<?xml version='1.0' encoding='UTF-8' ?> 
    <!-- was: <?xml version="1.0" encoding="UTF-8"?> --> 
    <beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:mvc="http://www.springframework.org/schema/mvc"

    http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> 

<context:component-scan base-package="demo.controller" /> 
<mvc:annotation-driven/> 

<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/> 

<!-- 
Most controllers will use the ControllerClassNameHandlerMapping above, but 
for the index controller we are using ParameterizableViewController, so we must 
define an explicit mapping for it. 
--> 
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> 
    <property name="mappings"> 
     <props> 
      <prop key="index.htm">indexController</prop> 
     </props> 
    </property> 
</bean> 

<bean id="viewResolver" 
     class="org.springframework.web.servlet.view.InternalResourceViewResolver" 
     p:prefix="/WEB-INF/jsp/" 
     p:suffix=".jsp" /> 

<!-- 
The index controller. 
--> 
<bean name="indexController" 
     class="org.springframework.web.servlet.mvc.ParameterizableViewController" 
     p:viewName="index" /> 

下面是web.xml中

<?xml version="1.0" encoding="UTF-8"?> 
    <web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</session-timeout> 
</session-config> 
<welcome-file-list> 
<welcome-file>redirect.jsp</welcome-file> 
</welcome-file-list> 
</web-app> 

我不知道什么是错，只要我打的Ajax控制器的路上，我得到 “GET http://localhost:8080/ajax/demo1 404（未找到）” 错误。请帮我解决我错在哪里。我尝试了几个解决方案，但他们没有解决问题。

Answer 1

尝试将应用程序名称添加到URL，

http://localhost:8080/[AppName]/ajax/demo1
