@RequestMapping annotation does not work if <context: component-scan / "> is in the application context instead of the dispatcher context
I am using Spring version 2.5.6 with <context: component-scan /> and @Autowired.
While I used SimpleUrlHandlerMapping in my dispatching context, everything was in order - auto installation worked fine, controllers correctly selected routes, etc.
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="urlMap">
<map>
<entry key="/login/login.html" value-ref="loginController" />
<entry key="/secured/index/index.html" value-ref="indexController" />
</map>
</property>
</bean>
Then I decided to use @RequestMapping to configure my routes in an XML file.
@Controller("loginController")
public class LoginController {
@RequestMapping("/login/login.html")
public ModelAndView login() {
ModelAndView model = new ModelAndView("login/login");
return model;
}
}
When I rewrote the code to use @RequestMapping , the problem started. The server (Tomcat) started giving me " No mapping for HTTP request with URI error .
