spring security LoginUrlAuthenticationEntryPoint

session 끊긴후 ajax 를 호출하면 상태값이 200 떨어지면서 정상처리 된다. AuthenticationException or AccessDeniedException

발생시 ExceptionTranslationFilter 에서 호출 하는듯 하다.

LoginUrlAuthenticationEntryPoint 에서 commence 메소드를 오버라딩 한다. AccessDeniedException 발생시 url 검사를 하여 ajax 포함 하고 있으면 response header 상태값을 403 으로 변화시킨다

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint;

public class AjaxAwareAuthenticationEntryPoint extends LoginUrlAuthenticationEntryPoint{
  public AjaxAwareAuthenticationEntryPoint(String loginUrl) {
    super(loginUrl);
  }

@Override
public void commence(
    HttpServletRequest request, 
    HttpServletResponse response, 
    AuthenticationException authException) 
        throws IOException, ServletException {

    boolean isAjax 
        = request.getRequestURI().contains("ajax");

    if (isAjax) {
        response.sendError(403, "Forbidden");
    } else {
        super.commence(request, response, authException);
    }
   }
}

ExceptionTranslationFilter 에 등록해서 사용 하지만 간단하게 사용시

    <bean id="exceptionTranslationFilter" class="org.springframework.security.web.access.ExceptionTranslationFilter">
     <property name="authenticationEntryPoint" ref="authenticationEntryPoint"/>
     <property name="accessDeniedHandler" ref="accessDeniedHandler"/>
    </bean>
    
    <bean id="authenticationEntryPoint"
         class="org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint">
     <property name="loginFormUrl" value="/login.jsp"/>
    </bean>
    
    <bean id="accessDeniedHandler" class="org.springframework.security.web.access.AccessDeniedHandlerImpl">
      <property name="errorPage" value="/accessDenied.htm"/>
    </bean>
