Spring url mapping does not work

Question

I have a problem with my url mappings in Spring MVC. My goal is to map a url with this form: "applicationName/app/".

Here is my web.xml:

<?xml version="1.0" ?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/app/*</url-pattern>
    </servlet-mapping>
</web-app>

And my Controller:

@Controller
public class Controller {

    @RequestMapping(value = "app/1")
    @ResponseBody
    public String test1 (){
        return "test1";
    }
}

I tried "/app/1" and "/app/1/", but my url mapping does not work.

Answer 1

配置了调度程序后，映射的方式将是

{contextPath}/app/app/1

Answer 2

在web.xml文件中，您使用的是/app/* ，在Controller中您再次给了app/1 ..so 2个app进入了URL映射。因此，请尝试按appName/app/app/1 。否则，从web.xml中删除该app
