Spring MVC : Ambiguous mapping found

I couldn't understand why the following gives an ambiguous mapping. a. The controller class ``` @Controller @RequestMapping("/employees") public class EmployeeController { @Autowired private EmployeeService employeeService; @RequestMapping(value = "/new", method = RequestMethod.GET) public String get(Model model) { return "xx"; } } ``` Console output: ``` java.lang.IllegalStateException: Ambiguous mapping found. Cannot map 'org.tutorial.spring.controller.EmployeeController#0' bean method public java.lang.String org.tutorial.spring.controller.EmployeeController.get(org.springframework.ui.Model) to {[/employees/new],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}: There is already 'employeeController' bean method public java.lang.String org.tutorial.spring.controller.EmployeeController.get(org.springframework.ui.Model) mapped. ``` It says method has already been mapped. How so? b. web.xml ``` <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app> ``` c. spring.xml ``` <context:annotation-config /> <context:component-scan base-package="org.tutorial.spring" /> <mvc:annotation-driven /> <bean class="org.tutorial.spring.controller.EmployeeController" /> ```
