Spring Security：如何向經過身份驗證的用戶添加額外的角色

Question

我有一個與REST服務和spring security一起使用的應用程序。 我具有基本身份驗證，並且需要進行硬登錄和軟登錄。

方案是：當用戶登錄時，他被分配了ROLE_SOFT並可以訪問需要ROLE_SOFT的URL，但是如果他想訪問需要ROLE_HARD的URL，則必須向指定的Web服務發送一些代碼或某些內容。

因此，我閱讀了此Acegi Security：如何為身份驗證向匿名用戶添加另一個GrantedAuthority

之后，我創建我的：

public class AuthenticationWrapper implements Authentication
{
   private Authentication original;

   public AuthenticationWrapper(Authentication original)
   {
      this.original = original;
   }


   public String getName() { return original.getName(); }
   public Object getCredentials() { return original.getCredentials(); }
   public Object getDetails() { return original.getDetails(); }   
   public Object getPrincipal() { return original.getPrincipal(); }
   public boolean isAuthenticated() { return original.isAuthenticated(); }
   public void setAuthenticated( boolean isAuthenticated ) throws IllegalArgumentException
   {
      original.setAuthenticated( isAuthenticated );
   }

public Collection<? extends GrantedAuthority> getAuthorities() {
    System.out.println("EXISTING ROLES:");
    System.out.println("Size=:"+original.getAuthorities().size());
    for (GrantedAuthority iterable : original.getAuthorities()) {

        System.out.println(iterable.getAuthority());
    }

    GrantedAuthority newrole = new SimpleGrantedAuthority("ROLE_HARD");
    System.out.println("ADD new ROLE:"+newrole.getAuthority());
    Collection<? extends GrantedAuthority> originalRoles = original.getAuthorities();

     ArrayList<GrantedAuthority> temp = new ArrayList<GrantedAuthority>(originalRoles.size()+1);
     temp.addAll(originalRoles);
     temp.add(newrole); 
     System.out.println("RETURN NEW LIST SIZE"+temp.size());
     for (GrantedAuthority grantedAuthority : temp) {
        System.out.println("NEW ROLES:"+grantedAuthority.getAuthority());
    }

    return Collections.unmodifiableList(temp);
}

和控制器

@Controller
@RequestMapping("/login")
public class LoginControllerImpl implements LoginController {


    LoginService loginService;


    @RequestMapping(method = RequestMethod.GET, headers = "Accept=application/json")
    @ResponseBody
    public User getUserSettings(){
        loginService=new LoginServiceImpl();
        Authentication auth =   SecurityContextHolder.getContext().getAuthentication();
        AuthenticationWrapper wrapper = new AuthenticationWrapper(auth);
        SecurityContextHolder.getContext().setAuthentication( wrapper );

        return loginService.getUser();
    }


}

但是在更改身份驗證后，我的會話中斷了。.也許有人知道更好的解決方案...

只是一個主意。如果用戶第一次使用登錄表單登錄並需要訪問資源向導，則需要其他權限，那么為什么不第二次將用戶重定向回登錄頁面呢？

    <http auto-config="true" use-expressions="true">
                <intercept-url pattern="/resources/**" access="denyAll"/>
                <intercept-url pattern="/login.do" access="permitAll"/>
                <intercept-url pattern="/role_soft_url_domain/* " access="hasRole('ROLE_SOFT') and fullyAuthenticated"/>
                <intercept-url pattern="/role_hard_url_domain/*" access="hasRole('ROLE_HARD') and fullyAuthenticated"/>             
                <intercept-url pattern="/*" access="hasRole('ROLE_SOFT')"/>
                <form-login login-page="/login.do" />               
                <logout invalidate-session="true"
                    logout-success-url="/"
                    logout-url="/j_spring_security_logout"/>
                </http>
