Question

当我尝试运行这个简单的html表单时：

   <html>
       <head>
        <title>Enter a new Page</title>
       </head>

       <body>

          <div id="editPresPage">
             <form action="editPresPage.do" method="post"> 
            <label>Enter Page ID</label><input type="text" name="page_id"/>
            <label>Enter Header1</label><input type="text" name="h1"/>
            <label>Enter Header2</label><input type="text" name="h2"/>
            <label>Enter Header3</label><input type="text" name="h3"/>
            <label>Enter Header4</label><input type="text" name="h4"/>            
            <label>Enter Page Text</label><input type="text" name="page_text"/>

            <input type="submit" value="Add New Page"/>
         </form>              
          </div>


       </body>
    </html>

我收到错误HTTP Status 500 - servlet的Servlet.init（）Dispatcher在我的浏览器中引发了异常。

在我的命令行窗口（当我运行tomcat的start.batch文件时打开）我收到以下错误：

log4j：WARN找不到appender 记录器（org.springframework.web.servlet.dispatcherservlet）

My Dispatcher-servlet.xml文件：

那就是我的控制器：

package my.pack.webTier.control;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

//@Controller
public class EditPresPageController {

    //@Autowired
    private Page_manager_service page_manager_service;

    public void setPage_manager_service(Page_manager_service page_manager_service) {
        this.page_manager_service = page_manager_service;
    }

    @RequestMapping("/editPresPage")
    public ModelAndView EditPresPage(@RequestParam("page_id") int page_id,
                                     @RequestParam("h1") String h1_value,
                                     @RequestParam("h2") String h2_value,
                                     @RequestParam("h3") String h3_value,
                                     @RequestParam("h4") String h4_value,
                                     @RequestParam("page_text") String page_text)

    {
        Presentation_page new_page=new Presentation_page(page_id,h1_value,h2_value,
                h3_value,h4_value,page_text);

        page_manager_service.create_new_page(new_page);


        return new ModelAndView("/thanks.html");

    }


}

我正在使用spring MVC 3.2，eclipse 3.7，springTomcat / 7.0.30并在我的项目中使用ANT。

我已经搜索了这个要求的答案 - 并没有找到答案。

Answer 1

您将调度员映射到* .do：

<servlet-mapping>
   <servlet-name>Dispatcher</servlet-name>
   <url-pattern>*.do</url-pattern>
</servlet-mapping>

但你的控制器是在没有.do：

的网址上映射的

@RequestMapping("/editPresPage")

尝试将其更改为：

@RequestMapping("/editPresPage.do")
