我是Spring Security的新手，在设置基本示例时遇到了主要问题。我试图运行这个例子http://javapointers.com/tutorial/spring-custom-userdetailsservice-example/，但我不适合我。这是代码：
控制器
/**
* Handles requests for the application home page.
*/
@Controller
public class HomeController {
private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
/**
* Simply selects the home view to render by returning its name.
*/
@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
logger.info("Welcome home! The client locale is {}.", locale);
Date date = new Date();
DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
String formattedDate = dateFormat.format(date);
model.addAttribute("serverTime", formattedDate );
return "home";
}
@RequestMapping(value = "/admin", method = RequestMethod.GET)
public String viewAdmin() {
return "admin";
}
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String viewLogin() {
return "login";
}
@RequestMapping(value = "/logout", method = RequestMethod.GET)
public String viewLogout() {
return "logout";
}
}
CustomUserDetailsService
@Service
public class CustomUserDetailsService implements UserDetailsService {
@Autowired
private UserService userService;
static final PasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
@Override
public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
Map<String, Object> userMap = userService.getUserByUsername(s);
//check if this user with this username exist, if not, throw an exception
// and stop the login process
if (userMap == null) {
throw new UsernameNotFoundException("User details not found with this username: " + s);
}
String username = (String) userMap.get("username");
String password = (String) userMap.get("password");
String role = (String) userMap.get("role");
List authList = getAuthorities(role);
//get the encoded password
String encodedPassword = passwordEncoder.encode(password);
User user = new User(username, encodedPassword, authList);
return user;
}
private List getAuthorities(String role) {
List authList = new ArrayList();
authList.add(new SimpleGrantedAuthority("ROLE_USER"));
//you can also add different roles here
//for example, the user is also an admin of the site, then you can add ROLE_ADMIN
//so that he can view pages that are ROLE_ADMIN specific
if (role != null && role.trim().length() > 0) {
if (role.equals("admin")) {
authList.add(new SimpleGrantedAuthority("ROLE_ADMIN"));
}
}
return authList;
}
}
用户服务
@Service("userService")
public class UserService {
public Map<String, Object> getUserByUsername(String username) {
Map<String, Object> userMap = null;
//logic here to get your user from the database
if (username.equals("admin") || username.equals("user")) {
userMap = new HashMap();
userMap.put("username", "admin");
userMap.put("password", "password");
//if username is admin, role will be admin, else role is user only
userMap.put("role", (username.equals("admin")) ? "admin" : "user");
//return the usermap
return userMap;
}
//if username is not equal to admin, return null
return null;
}
}
