[英]No mapping found for HTTP request with URI xxx in DispatcherServlet with name xx
我查看了幾乎所有關於該錯誤的主題，但沒有一個對我有用。
我創建了一個簡單的Spring MVC項目，當我運行該項目時，我得到了這個錯誤：
févr. 19, 2016 12:29:56 PM org.springframework.web.servlet.PageNotFound noHandlerFound
AVERTISSEMENT: No mapping found for HTTP request with URI [/SpringMVCsample1/] in DispatcherServlet with name 'one'
這是我的代碼：

public String printHello(ModelMap model) {
model.addAttribute("message", "Hello Spring MVC Framework!");
return "hello";

}
hello.jsp：

<title>Insert title here</title>
</head>
<body>
<h2>${message}</h2>
</body>
</html>
有任何想法嗎 ？
在web xml中更改url-pattern：
<url-pattern>/*</url-pattern>
更改控制器以具有根上下文的映射：
package com.capgemini.springtest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.ui.ModelMap;
@Controller
public class OneController {
@RequestMapping(value = {"/","/hello"}, method = RequestMethod.GET)
public String printHello(ModelMap model) {
model.addAttribute("message", "Hello Spring MVC Framework!");
return "hello";
}
}
hello.jsp應該位於文件夾：/WEB-INF/jsp/hello.jsp下
當然你會遇到這樣的問題，因為你沒有任何控制器來處理請求“/”你要做的就是添加一個控制器或在你的web文件夾下添加index.jsp
web
|--->WEB-INF
| |--->jsp
| |---->index.jsp
|--->index.jsp
在web.xml您的servlet僅映射/ URI。 URL模式應該是/* 。
嘗試將<mvc:annotation-driven />到one-servlet.xml中 。 記得在那里添加mvc名稱空間的定義xmlns:mvc="http://www.springframework.org/schema/mvc"
然后嘗試訪問localhost:8080/SpringMVCsample1/hello 。 不是localhost:8080/SpringMVCsample1/hello/就像你說過你在其中一條評論中嘗試過的那樣
