無法通過Ajax調用命中Spring MVC控制器

Question

1，下面是我在index.jsp中的ajax調用

    <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.下面是控制器的代碼

  @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.下面是調度員的代碼

   <?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" 
   xmlns:p="http://www.springframework.org/schema/p"
   xmlns:aop="http://www.springframework.org/schema/aop"
   xmlns:tx="http://www.springframework.org/schema/tx"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="http://www.springframework.org/schema/beans  
   http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
   http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
   http://www.springframework.org/schema/tx 
   http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context.xsd
   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" />

4. 下面是web.xml

     <?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" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> <listener> <listener- class>org.springframework.web.context.ContextLoaderListener</listener- class> </listener> <servlet> <servlet-name>dispatcher</servlet-name> <servlet- class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.htm</url-pattern> </servlet-mapping> <session-config> <session-timeout> 30 </session-timeout> </session-config> <welcome-file-list> <welcome-file>redirect.jsp</welcome-file> </welcome-file-list> </web-app> 

我不知道這是怎么回事，每當我在ajax中命中控制器的路徑時，都會出現“ GET http：// localhost：8080 / ajax / demo1 404（未找到）”錯誤。 請幫我解決我錯了的地方。 我嘗試了很少的解決方案，但是他們沒有解決問題。

Answer 1

嘗試將應用程序名稱添加到url，

HTTP：//本地主機：8080 / [AppName的] / AJAX / demo1的
