Spring method security does not work for me

i am new to spring security.

i try to use spring security in my application. the basic spring security functionality works fine.

but when i try to secure methods to allow only for specific role, it does not secured and that method can work for every role.

here i given my code snippet. may i know where i did mistake.

library that i used for this application are

import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
import com.spt3.infc.ActionInterface;

    public ActionController(){
    }

    public ModelAndView getResult(HttpServletRequest request,HttpServletResponse response)throws Exception{
        System.out.println(" - - - - - getResult() - - - - - ");
        try{
            this.getPersonalInformation("MD");
        }catch(Exception e){
            System.out.println(" Exception : "+e);

    }

    public void getPersonalInformation(String role){
        System.out.println(" "+role+"'s-Personal Information.");
    }
}

ActionInterface.java

package com.spt3.infc;

import org.springframework.security.access.prepost.PreAuthorize;
public interface ActionInterface {

    @PreAuthorize("hasRole('MD')") // Secured method only for role MD
    public void getPersonalInformation(String role);
}

When accessing getResult() method from url ( http://127.0.0.1:8080/myapp/action.htm?action=getResult) secured method can be invoked.

My Expected Result should be

Now Actual Result is

After using beans - Edited (1) Here

Same problem has been occurred when using bean injection.

Here i changed the files with the code snippet.

ActionController.java is like

package com.spt3.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
import com.spt3.infc.ActionInterface;

public class ActionController extends MultiActionController {

    private ActionInterface actionInterface;

    public ActionController(){
    }

    public ActionController(ActionInterface actionInterface){
        this.actionInterface=actionInterface;
    }

    public ModelAndView getResult(HttpServletRequest request,HttpServletResponse response)throws Exception{
        System.out.println(" - - - - - getResult() - - - - - ");
        try{
            actionInterface.getPersonalInformation("MD");
        }catch(Exception e){
            System.out.println(" Exception : "+e);
        }
        return new ModelAndView("result");
    }

}

ActionInterface.java

package com.spt3.infc;

public interface ActionInterface {

    public void getPersonalInformation(String role);
}

bean class called ActionBean.java

package com.spt3.bean;


import com.spt3.infc.ActionInterface;
import org.springframework.security.access.annotation.Secured;

public class ActionBean implements ActionInterface{

    @Secured("MD")
    public void getPersonalInformation(String role){
        System.out.println(" "+role+"'s-Personal Information.");
    }

}

i used constructor injection to inject the object.

<bean id="actionBean" class="com.spt3.bean.ActionBean"/> <!-- Bean class -->
<bean name="/action.htm" id="action" class="com.spt3.controller.ActionController">
        <property name="methodNameResolver">
            <ref bean="paramResolver"/>
        </property>
        <constructor-arg index="0" ref="actionBean"/> <!-- Injecting object to controller -->
    </bean>

Where i did mistake. please give me the solution.

The problem is solved.

These are the steps i followed.

  1. Configure bean in appropriate xml file
  2. I used bean injection.
  3. i used @PreAuthorize annotation.

Finally the classes are looks like the following snippet when the program is successfully ran.

ActionBean is a separate class i created and i implemented ActionInterface.java class and implemented the method getPersonalInformation() method.

ActionInterface.java looks like this

package com.spt3.infc;

public interface ActionInterface {

    public void getPersonalInformation(String role);
}

and ActionBean.java looks like this

package com.spt3.bean;


import com.spt3.infc.ActionInterface;
import org.springframework.security.access.prepost.PreAuthorize;

public class ActionBean implements ActionInterface{

    @PreAuthorize("hasRole('MD')")
    public void getPersonalInformation(String role){
        System.out.println(" "+role+"'s-Personal Information.");
    }

}

ActionController.java is look like this

package com.spt3.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
import com.spt3.infc.ActionInterface;

public class ActionController extends MultiActionController {

    private ActionInterface actionInterface;

    public ActionController(){
    }

    public ActionController(ActionInterface actionInterface){
        this.actionInterface=actionInterface;
    }

    public ModelAndView getResult(HttpServletRequest request,HttpServletResponse response)throws Exception{
        System.out.println(" - - - - - getResult() - - - - - ");
        try{
            actionInterface.getPersonalInformation("MD");
        }catch(Exception e){
            System.out.println(" Exception : "+e);
        }
        return new ModelAndView("result");
    }

}

Good luck... Thanks a lot.

Spring security works by using proxies around the spring beans, which intercept the calls to methods of the beans, and throw an exception if the user doesn't have the appropriate role. But your controller doesn't call any spring bean method. It does call an instance method : this.getPersonalInformation().

When doing this, you're not calling another Spring bean method, so Spring can't intercept the call, and thus can't verify that the user has the appropriate roles.

Put the getPersonalInformation method in another Spring bean, inject this bean in your controller, and all should be fine.

Side note : why not simply using the @Secured("MD") annotation for such a case? And why not put the annotation on the getResult method directly?
