org.springframework.web.servlet.DispatcherServlet noHandlerFound：Spring MVC

Question

I am new to spring MVC. 我是春季MVC的新手。 I tried creating small hello world app but it is not running as expected. 我尝试创建小的Hello World应用程序，但未按预期运行。 I am always getting error org.springframework.web.servlet.DispatcherServlet noHandlerFound WARNING: No mapping found for HTTP request with URI [/FitnessTracker/greeting.html] in DispatcherServlet with name 'fitTrackerServlet' 我总是收到错误org.springframework.web.servlet.DispatcherServlet noHandlerFound警告：在DispatcherServlet中，名称为“ fitTrackerServlet”的URI [/FitnessTracker/greeting.html]的HTTP请求找不到映射。

I know this error is very common and there are lots of links available on the google but none of them worked for me. 我知道这个错误非常普遍，Google上有很多可用的链接，但没有一个对我有用。 Any help would be appreciated. 任何帮助，将不胜感激。

Here is the code snippet 这是代码片段

HelloController.java HelloController.java

@Controller
public class HelloController {

@RequestMapping(value = "/greeting")    
public String sayHello(Model model) {
model.addAttribute("greeting","Hello World!!!!");
return "hello";
}}

Answer 1

The URL /greeting does not have any .html at the end, so the servlet will not going to use the DispatcherServlet, because *.html pattern does not match the /greeting, and this will result in 404. URL /greeting末尾没有任何.html ，因此Servlet将不会使用DispatcherServlet，因为*.html模式与/ greeting不匹配，这将导致404。

Change your web.xml such: 更改您的web.xml，例如：

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