SPRINGMVC build Environment times No mapping found for HTTP request with URI [/exam3/welcome] in Dispatcherservlet with name ' Spring2 '

Project is using spring MVC

(1) Access in the browser, the background total error:

Java code

1. No mapping found for HTTP request with URI [/exam3/welcome] in Dispatcherservlet with name ' spring2 '

Checked the long time, only to find that the controller did not scan.

I am using the annotations.

The spring MVC configuration file is as follows:

XML code

The controller's directory structure is as follows:

(2) After the problem is resolved, the error is:

No mapping found for HTTP request with URI [/exam3/web-inf/jsp/welcome.jsp] in Dispatcherservlet with name ' Spring2 '

The result is that the Web. XML is configured with a problem, the following is problematic:

XML code

2. <servlet>
4. <servlet-name>spring2</servlet-name>
6. <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class >
8. <load-on-startup>1</load-on-startup>
10. </servlet>
12. <servlet-mapping>
14. <servlet-name>spring2</servlet-name>
16. <url-pattern>/*</url-pattern>
18. </servlet-mapping>

Workaround: Change Url-pattern from/* To/
