I have a spring 3 application with the configurations given below. When any user tries to access a page and he/she isn't logged in, I get an Access is Denied exception with an ugly stack trace. How do I handle this exception and not let it dump out a stack trace. I implemented my own access-denied-handler but that doesn't get invoked.
Based on the type of the requested resource, I would like to show custom error messages or pages. Here is my spring configuration.
How do I get Spring to invoke my access-denied-handler . Here is my spring configuration
<security:http auto-config='true'>
<security:intercept-url pattern="/static/**" filters="none"/>
<security:intercept-url pattern="/login" filters="none"/>
<security:intercept-url pattern="/**" access="ROLE_USER" />
<security:form-login login-page="/index"
default-target-url="/home" always-use-default-target="true"
authentication-success-handler-ref="AuthenticationSuccessHandler"
login-processing-url="/j_spring_security_check"
authentication-failure-url="/index?error=true"/>
<security:remember-me key="myLongSecretCookieKey" token-validity-seconds="1296000"
data-source-ref="jdbcDataSource" user-service-ref="AppUserDetailsService" />
<security:access-denied-handler ref="myAccessDeniedHandler" />
</security:http>
<bean id="myAccessDeniedHandler"
class="web.exceptions.handlers.AccessDeniedExceptionHandler">
<property name="errorPage" value="/public/403.htm" />
</bean>
The custom class for handling this exception is given below
public class AccessDeniedExceptionHandler implements AccessDeniedHandler
{
private String errorPage;
@Override
public void handle(HttpServletRequest request, HttpServletResponse response,
AccessDeniedException arg2) throws IOException, ServletException {
response.sendRedirect(errorPage);
}
public void setErrorPage(String errorPage) {
if ((errorPage != null) && !errorPage.startsWith("/")) {
throw new IllegalArgumentException("errorPage must begin with '/'");
}
this.errorPage = errorPage;
}
}
When I run this application, this is the error that I get. I am only pasting a part of the stacktrace and the Spring Debug logs.
20:39:46,173 DEBUG AffirmativeBased:53 - Voter: org.springframework.security.access.vote.RoleVoter@5b7da0d1, returned: -1
20:39:46,173 DEBUG AffirmativeBased:53 - Voter: org.springframework.security.access.vote.AuthenticatedVoter@14c92844, returned: 0
20:39:46,178 DEBUG ExceptionTranslationFilter:154 - Access is denied (user is anonymous); redirecting to authentication entry point
org.springframework.security.access.AccessDeniedException: Access is denied
at org.springframework.security.access.vote.AffirmativeBased.decide(AffirmativeBased.java:71)
at org.springframework.security.access.intercept.AbstractSecurityInterceptor.beforeInvocation(AbstractSecurityInterceptor.java:204)
How do I fix this problem? Firstly, I want to stop spring from Throwing that exception. If it still throws it, I want to handle it and not raise any flags.
Update: I have attached a part of my web.xml as well.
