下面是我的PageController.java类

package com.fayis.shopping.controller;


import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class PageController {

@RequestMapping(value = {"/","/home","/index"})
public ModelAndView index()
{
    ModelAndView mv=new ModelAndView("page");
    mv.addObject("greeting", "Hi");
    return mv;
}

}

2 个答案:

答案 0 :(得分：0)

您尚未指定servlet容器，但是例如在tomcat中，要进入您的应用，您必须在网址中包含war文件名，例如：localhost:8080/your_app-1.0-SNAPSHOT

第二个web.xml中有<url-pattern>/</url-pattern>，它仅映射/，而不会映射/index或/home。 要匹配此URL，您的模式应类似于<url-pattern>/*</url-pattern>

答案 1 :(得分：0)

现在有效。就像奇迹一样。当我更新dispatcher-servlet spring bean定义时，它起作用了。后来我把它改回来，仍然可以工作。
