找不到RequestMapping DisplatcherServlet映射

问题描述

我的DispatcherServlet无法正常工作.

My DispatcherServlet is not working correctly.

  <servlet>
    <servlet-name>userService</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/classes/servlet/userService-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>userService</servlet-name>
    <url-pattern>/user/*</url-pattern>
  </servlet-mapping>

控制器:

@Controller
@RequestMapping(value ="/user")
public class Controller {

    @RequestMapping(method = RequestMethod.GET)
    @ResponseStatus(HttpStatus.OK)
    public @ResponseBody List<User> getUsers() {
    }

    @RequestMapping( value = "/{id}", method = RequestMethod.GET)
    @ResponseStatus(HttpStatus.OK)
    public @ResponseBody User getUser(@PathVariable int id) throws NotFoundException {
    }

    @RequestMapping( value = "/remove/{id}", method = RequestMethod.DELETE)
    @ResponseStatus(HttpStatus.OK)
    public void delete(@PathVariable int id) throws NotFoundException {
    }
}

servlet:

当我尝试使用"/user"获取所有用户时，它可以正常工作，但是当我尝试获取特定的用户时，例如"user/75".75代表我得到的{id}:

When I try ´/user´ to get all users it workings fine but when i try to get certain user for example ´user/75´. 75 representing the {id} I'm getting:

No mapping found for HTTP request with URI [/user/75] in DispatcherServlet with name 'userService'

不确定为什么.我的网址格式错误吗?谢谢您的帮助.

not sure why. is my url-pattern wrong? thanks for any help.

推荐答案

将web.xml的< url-pattern>/user/*</url-pattern> 行更改为< url-pattern>/</url-pattern>

Change the line <url-pattern>/user/*</url-pattern> of your web.xml to <url-pattern>/</url-pattern>

此更改使Dispatcher Servlet捕获'/'下的所有请求，而在先前的配置中，它捕获/user下的所有请求(这意味着控制器的find方法将映射到/user/user/{id})

This change makes the Dispatcher Servlet catch all requests under '/' whereas in your previous configuration it was catching everying under /user (meaning that your controller's find method would be mapped at /user/user/{id})
