The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler

Question

I wanted to use both annotation mapping and xml mapping in Spring MVC. My application-context.xml as follows:

<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">         <property name="mappings">             <props>                 <prop key="personal/account/history">accountHistoryController</prop>             </props>         </property>     </bean>      <bean id="accountHistoryController" class="com.fg.banking.ib.controller.AccountHistoryController" />      <bean         class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>     <context:annotation-config />     <mvc:annotation-driven />     <context:component-scan base-package="com.fg.banking.ib.controller, com.fg.banking.ib.helper, com.fg.banking.corporate.controller" /> 

I am getting the following error when I try to access the url. I have configured the SimpleControllerHandlerAdapter as above.

javax.servlet.ServletException: No adapter for handler  [com.fg.banking.ib.controller.AccountHistoryController@218531e6]: The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler org.springframework.web.servlet.DispatcherServlet.getHandlerAdapter(DispatcherServlet.java:1128) org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:903) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:856) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:936) org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:827) 

What to do?

This error also occurs when you define a restController but forget to define the requestMapping.

@RestController @RequestMapping("/api/orders") // <---- dont't forget the requestMapping
