我正在使用DaoAuthenticationProvider进行身份验证,但是当我提交表单时,super.authenticate(身份验证)会两次调用loadUserByUsername,它会抛出BadCredentialsException然后下次成功登录
如果我不使用passwordencoder这个过程工作正常但是当我使用它时,loadUserByUsername方法被调用两次。
以下是我的代码:
SecurityConfig
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
@Qualifier("authenticationProvider")
AuthenticationProvider authenticationProvider;
@Autowired
@Qualifier("userDetailsService")
UserDetailsService userDetailsService;
@Bean
public PasswordEncoder passwordEncoder() {
PasswordEncoder encoder = new BCryptPasswordEncoder();
return encoder;
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth)
throws Exception {
auth.authenticationProvider(authenticationProvider)
.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/admin/**")
.access("hasRole('ROLE_ADMIN')").and().formLogin()
.loginPage("/login").failureUrl("/login?error")
.usernameParameter("username").passwordParameter("password")
.and().logout().logoutSuccessUrl("/login?logout").and().csrf()
.and().exceptionHandling().accessDeniedPage("/403");
}
}
身份验证类
@Component("authenticationProvider")
public class LimitLoginAuthenticationProvider extends DaoAuthenticationProvider {
@Autowired
@Qualifier("userDetailsService")
@Override
public void setUserDetailsService(UserDetailsService userDetailsService) {
super.setUserDetailsService(userDetailsService);
}
@Override
public Authentication authenticate(Authentication authentication)
throws AuthenticationException {
try {
System.out.println("inside authenticate");
Authentication auth = super.authenticate(authentication);
return auth;
} catch (BadCredentialsException be) {
System.out.println("First call comes here ");
throw be;
} catch (LockedException e) {
throw e;
}
}
}
MyUserdetailsService类implments UserDetailsService
@Service("userDetailsService")
public class MyUserDetailsService implements UserDetailsService {
@Autowired
private UserDao userDao;
/* below method is called twice if I am using passwordencoder,
initially authentication fails and then again immediately
on second call authentication succeed */
@Transactional(readOnly=true)
@Override
public UserDetails loadUserByUsername(final String username) throws UsernameNotFoundException {
com.mkyong.users.model.User user = userDao.findByUserName(username);
List<GrantedAuthority> authorities = buildUserAuthority(user.getUserRole());
return buildUserForAuthentication(user, authorities);
}
private User buildUserForAuthentication(com.mkyong.users.model.User user, List<GrantedAuthority> authorities) {
MyUserDetails myUserDetails = new MyUserDetails (user.getUsername(), user.getPassword(), user.isEnabled(), user.isAccountNonExpired(), user.isAccountNonLocked(), user.isCredentialsNonExpired(), user.getEmailId(),authorities);
return myUserDetails;
}
private List<GrantedAuthority> buildUserAuthority(Set<UserRole> userRoles) {
Set<GrantedAuthority> setAuths = new HashSet<GrantedAuthority>();
// Build user's authorities
for (UserRole userRole : userRoles) {
setAuths.add(new SimpleGrantedAuthority(userRole.getRole()));
}
List<GrantedAuthority> Result = new ArrayList<GrantedAuthority>(setAuths);
return Result;
}
}
有些人可以帮助我。我相信SecurityConfig类需要进行一些更改,但确切地说我无法弄明白。
答案 0 :(得分:2)
最后,在java_dude和SergeBallesta的帮助下,我得到了我的查询的解决方案。
经过大量调试后,我看到当在AaoAuthenticationProvider类中调用isPasswordValid方法而不是调用方法1 时,它从org.springframework.security调用方法2 .authentication.encoding.PlaintextPasswordEncoder哪一个被折旧,在第二次调用时它正在调用isPasswordValid 方法1。
方法1
public boolean isPasswordValid(String encPass, String rawPass, Object salt) {
checkSalt(salt);
return delegate.matches(rawPass, encPass);
}
方法2
public boolean isPasswordValid(String encPass, String rawPass, Object salt) {
String pass1 = encPass + "";
// Strict delimiters is false because pass2 never persisted anywhere
// and we want to avoid unnecessary exceptions as a result (the
// authentication will fail as the encodePassword never allows them)
String pass2 = mergePasswordAndSalt(rawPass, salt, false);
if (ignorePasswordCase) {
// Note: per String javadoc to get correct results for Locale insensitive, use English
pass1 = pass1.toLowerCase(Locale.ENGLISH);
pass2 = pass2.toLowerCase(Locale.ENGLISH);
}
return PasswordEncoderUtils.equals(pass1,pass2);
}
要正确地进行身份验证,只需在SecurityConfig类中添加以下代码,并添加到我当前的相关代码中。
@Bean
public DaoAuthenticationProvider authProvider() {
// LimitLoginAuthenticationProvider is my own class which extends DaoAuthenticationProvider
final DaoAuthenticationProvider authProvider = new LimitLoginAuthenticationProvider();
authProvider.setUserDetailsService(userDetailsService);
authProvider.setPasswordEncoder(passwordEncoder());
return authProvider;
}
**并更改此方法代码**
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(authProvider())
.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}
