漂亮的URL映射与Spring 3.0 [英] Pretty URL Mapping with Spring 3.0

问题描述

当尝试将一个名为new的URL路径映射到具有某种逻辑的Controller方法时，会出现以下错误，然后显示视图index.jsp：

警告：在名为'springguestbook'的DispatcherServlet中未找到具有URI [/springguestbook/index.jsp]的HTTP请求的映射

这是我的Controller方法：

  @RequestMapping（value =/ list方法= RequestMethod.GET）
 public String showGuestbookEntries（HttpServletRequest请求，模型模型）{
 HttpSession session = request.getSession（true）; 
 this.guestbookService = GuestbookService.getInstance（session）; 
 model.addAttribute（guestbookEntries，
 guestbookService.getGuestbookEntries（））; 
 
 returnindex; 
 
} 
  

这些是我的web.xml文件的内容： / p>

 < display-name> Spring留言簿< / display-name> 
 
< servlet> 
< servlet-name> springguestbook< / servlet-name> 
< servlet-class> org.springframework.web.servlet.DispatcherServlet 
< / servlet-class> 
< load-on-startup> 1< / load-on-startup> 
< / servlet> 
< servlet-mapping> 
< servlet-name> springguestbook< / servlet-name> 
< url-pattern> / *< / url-pattern> 
< / servlet-mapping> 
  

这是我的ViewResolver的配置：

 < bean id =viewResolver
 class =org.springframework.web.servlet.view.InternalResourceViewResolver> 
< property name =prefixvalue =//> 
< property name =suffixvalue =。jsp/> 
< / bean> 
  

在我看来，不是实际读取index.jsp的内容并显示它们，只是重定向到index.jsp。
如何解决这个问题？

解决方案

两件事：

1. 尝试将您的servlet映射更改为此（将 / * 更改为 / ）：

    < servlet-mapping> 
   < servlet-name> springguestbook< / servlet-name> 
   < url-pattern> /< / url-pattern> 
   < / servlet-mapping> 
     




2. 确保您使用的视图解析器可以找到您的JSP，例如 InternalResourceViewResolver ：

     @Bean 
    public ViewResolver viewResolver b $ b InternalResourceViewResolver b = new InternalResourceViewResolver（）; 
    b.setPrefix（/ WEB-INF / jsp /）; 
    b.setSuffix（。jsp）; 
    return b; 
   } 
     
    

>

 < bean id =viewResolverclass =org.springframework.web.servlet.view.InternalResourceViewResolver> 
< property name =prefixvalue =/ WEB-INF / jsp //> 
< property name =suffixvalue =。jsp/> 
< / bean> 
  

I'm getting the following error when trying to map a URL path called "new" to a Controller method which does some logic, then displays the view "index.jsp":

WARNING: No mapping found for HTTP request with URI [/springguestbook/index.jsp] in DispatcherServlet with name 'springguestbook'

This is my Controller method:

@RequestMapping(value = "/list", method = RequestMethod.GET)
public String showGuestbookEntries(HttpServletRequest request, Model model) {
    HttpSession session = request.getSession(true);
    this.guestbookService = GuestbookService.getInstance(session);
    model.addAttribute("guestbookEntries",
            guestbookService.getGuestbookEntries());

    return "index";

}

These are the contents of my web.xml file:

<display-name>Spring Guestbook</display-name>

<servlet>
    <servlet-name>springguestbook</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>springguestbook</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

And this is the configuration of my ViewResolver:

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

It seems to me that instead of actually reading the contents of index.jsp and displaying them, the method just redirects to index.jsp instead. How do I fix this?

解决方案

Two things:

1. Try changing your servlet mapping to this (change /* to /):

   <servlet-mapping>
       <servlet-name>springguestbook</servlet-name>
       <url-pattern>/</url-pattern>
   </servlet-mapping>
   

2. Make sure you're using a view resolver that can find your JSP, like InternalResourceViewResolver:

   @Bean
   public ViewResolver viewResolver() {
       InternalResourceViewResolver b = new InternalResourceViewResolver();
       b.setPrefix("/WEB-INF/jsp/");
       b.setSuffix(".jsp");
       return b;
   }
   

or

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