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

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)

What to do?

Answer 1

This error also occurs when you define a restController but forget to define the requestMapping.
#RestController
#RequestMapping("/api/orders") // <---- dont't forget the requestMapping

Answer 2

This problem occurred for me when I tried to define RestController path by using in this way:
#RestController("/test")
public class TestController {}
In the above section, the meaning of this declaration is different. Here actually "/test" is defined as bean name rather than path for the controller.
After defining the path in this way it worked for me:
#RestController
#RequestMapping("/test")
public class TestController {}

Answer 3

I resolved the issue. I forgot to add the #Controller annotation in controller class. There are fore we can use the both methods(annotation mapping & XML mapping) together in an application.

Answer 4

Try adding the following as a handler mapper(Worked for me):
<bean id="HandlerMapping" class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>

Answer 5

Make sure you have implemented Controller in your controller classes and overrided handleRequest method.

Answer 6

Here our controller class should extends
import org.springframework.web.servlet.mvc.AbstractController;
public class AppController extends AbstractController{ }
Here we need to implement the abstract method as :
protected modelandview handleRequestInternal(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception { return null; }
