spring mvc HTTP Status 404基本启动
我无法弄清楚此代码中的问题。我没有收到主页，控制台也没有显示错误。
的web.xml：
<web-app>
<display-name>Myapp</display-name>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
dispatcher-servlet.xml：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

</beans>
家庭控制器：
package com.sim.market.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/home")
public class HomeController {
public String showHome(){
System.out.println("calloing");
return "home";
}
}
在控制台上没有错误，但浏览器错误是
HTTP Status 404 -

谁能帮我吗？提前谢谢。
从eclipse运行应用程序时，它显示以下日志：

当我像home.do一样调用资源时 它显示：

3 个答案:
答案 0 :(得分：1)
你应该在web.xml中添加它
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
将此代码段添加到index.jsp
<meta HTTP-EQUIV="REFRESH" content="0; url=${pageContext.request.contextPath}/home.do">
每次我在Spring mvc中创建应用程序时，我发现这是一个不错的选择
答案 1 :(得分：0)
使用showHome()注释您的@RequestMapping方法，将其标识为处理程序。如果没有它，你的控制器就没有处理程序方法，因此无需处理请求。
显然，你在@RequestMapping上添加限制，比如处理哪些HTTP方法，它可能包含哪些标题，甚至专门化应该处理的路径。
答案 2 :(得分：0)
您需要为您的请求进行映射。
@RequestMapping (value = "/showhome", method = {RequestMethod.GET, RequestMethod.POST})
public String showHome(ModelMap model, HttpServletRequest request) { }
