警告: No mapping found for HTTP request with URI [/user/test] in DispatcherServlet with name 'springDi

报错

五月 20, 2019 5:41:55 下午 org.springframework.web.servlet.DispatcherServlet noHandlerFound
警告: No mapping found for HTTP request with URI [/user/test] in DispatcherServlet with name 'springDispatcherServlet'

原因

应该将applicationContext.xml（我将springmvc的配置也放在了spring配置文件中）放到resource目录下面
原来在src下面，在web.xml中的配置就没有读取到applicationContext.xml配置文件，springmvc的扫描也没有找到。

在maven的项目中springmvc的配置文件放在resource下面后者WEB-INF下面

代码

@Controller
@RequestMapping("/user")
public class UserController {

	@Autowired
	private UserService userService;

	@RequestMapping("/test")
	public String test(User user,ModelMap model){
		userService.save(user);
		model.addAttribute(user);
		return "/return";
	}

}

web.xml

<!--springmvc-->
    <servlet>
        <servlet-name>springDispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <servlet-mapping>

applicationContext.xml
