I am a newbie to Spring Security and CAS. I got the SSO part working but am struggling with getting the authorization part working. I followed this to implement custom authorisation

http://www.theserverside.com/tip/-Spring-Security-Customizing-Your-User-and-Authorization-in

When should the loadUserDetails get called. I have set a break point here and this method is never called.

Any help will be greatly appreciated. Looks like I am missing a configuration to invoke the authorization.

I want to have my custom User object populated with the authorities and reside in session so that I can check User role at any stage.

When I log in the logs here is steps that happen once I login

My custom UserDetails

My custom UserService

public class CustomUserService implements UserDetailsService, AuthenticationUserDetailsService {

@Override
public UserDetails loadUserByUsername(String username)
        throws UsernameNotFoundException {
    System.out.println("loadUserByUsername called here ");
    User currentUser = new User("Reena");
    //Collection<SimpleGrantedAuthority> authorities  = currentUser.getAuthorities();
    List<String> roles = new ArrayList<String>();
    roles.add("ROLE_Admin");
    roles.add("ROLE_CPAD-Maintenance");
    currentUser.setUserAuthorities(roles);
    //authorities.add(new SimpleGrantedAuthority("PRIVILEGE_HOME"));
    return currentUser;
}

@Override
public UserDetails loadUserDetails(Authentication token) throws UsernameNotFoundException{
    User currentUser = new User("Reena");
    List<String> roles = new ArrayList<String>();
    roles.add("ROLE_Admin");
    roles.add("ROLE_CPAD-Maintenance");
    currentUser.setUserAuthorities(roles);
    //authorities.add(new SimpleGrantedAuthority("PRIVILEGE_HOME"));
    return currentUser;
}
}

CasAuthenticationProvider仅在身份验证为空时调用 userDetailsS​​ervice

我建议在 CasAuthenticationProvider.java 中放置一个调试点（请参阅以下代码中的我的评论）

 public class CasAuthenticationProvider {
 public Authentication authenticate(Authentication authentication) throws AuthenticationException {

    CasAuthenticationToken result = null;

    if (stateless) {
        // Try to obtain from cache
        result = statelessTicketCache.getByTicketId(authentication.getCredentials().toString());
    }

    if (result == null) {
        //following line calls userDetailsService. I would recommend to put a debug point here 
        ///if it is not calling userDetailsService, that means result is not null

        result = this.authenticateNow(authentication);
        result.setDetails(authentication.getDetails());
    }

    if (stateless) {
        // Add to cache
        statelessTicketCache.putTicketInCache(result);
    }

    return result;
}

您可以从http://mvnrepository.com/artifact/org.springframework.security/spring-security-cas-client下载源代码并将其附加到 eclipse。
