在使用 spring security 时,我在 stackoverflow 中看到了一个有趣的线程,其中要求对两组用户进行身份验证,以防止员工反对不同的身份验证提供商 LDAP
和针对 DATABASE
的客户。 Thread 提出了公认的解决方案,使用带有单选按钮的单一登录表单来区分员工和客户,并使用自定义身份验证过滤器,根据用户类型区分登录请求,并设置不同的 authenticationToken(customerAuthToken /employeeAuthToken) 并请求进行身份验证。将有两个 AuthenticationProvider
实现,身份验证由支持的 token 完成和决定。
通过这种方式,线程能够提供有趣的解决方案来避免 spring security 默认提供的回退身份验证。
看看线程Configuring Spring Security 3.x to have multiple entry points
因为答案完全在 xml 配置中。我只是想让解决方案在 Java 配置中可用。我会在回答中发布它。
现在我的问题,随着 spring 版本的发展,除了我的答案之外,是否有可能通过任何新功能/最小配置具有相同的功能?
最佳答案
自 this thread鉴于完整的信息,我只是发布代码以供 java 配置引用。
这里我假设以下事情
1. 用户和管理员作为两组用户。
2. 为简单起见,两者都使用内存验证。
- 如果 userType 是用户,则只有用户凭据应该有效。
- 如果 userType 是 Admin,则只有管理员凭据才有效。
- 并且应该能够为不同的权限提供相同的应用程序接口(interface)。
和代码

CustomAuthenticationFilter
@Component
public class MyAuthenticationFilter extends UsernamePasswordAuthenticationFilter
{
@Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException
{
UsernamePasswordAuthenticationToken authToken = null;
if ("user".equals(request.getParameter("userType")))
{
authToken = new UserUsernamePasswordAuthenticationToken(request.getParameter("userName"), request.getParameter("password"));
}
else
{
authToken = new AdminUsernamePasswordAuthenticationToken(request.getParameter("userName"), request.getParameter("password"));
}
setDetails(request, authToken);
return super.getAuthenticationManager().authenticate(authToken);
}
}
CustomAuthentictionTokens
public class AdminUsernamePasswordAuthenticationToken extends UsernamePasswordAuthenticationToken
{
public AdminUsernamePasswordAuthenticationToken(Object principal, Object credentials)
{
super(principal, credentials);
}
public AdminUsernamePasswordAuthenticationToken(Object principal, Object credentials,
Collection<? extends GrantedAuthority> authorities)
{
super(principal, credentials, authorities);
}
}
public class UserUsernamePasswordAuthenticationToken extends UsernamePasswordAuthenticationToken
{
public UserUsernamePasswordAuthenticationToken(Object principal, Object credentials)
{
super(principal, credentials);
}
public UserUsernamePasswordAuthenticationToken(Object principal, Object credentials,
Collection<? extends GrantedAuthority> authorities)
{
super(principal, credentials, authorities);
}}
CustomAuthentictionProvider - 对于管理员
@Component
public class AdminCustomAuthenticationProvider implements AuthenticationProvider
{
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException
{
String username = authentication.getName();
String password = authentication.getCredentials().toString();
if (username.equals("admin") && password.equals("admin@123#"))
{
List<GrantedAuthority> authorityList = new ArrayList<>();
GrantedAuthority authority = new SimpleGrantedAuthority("ROLE_ADMIN");
authorityList.add(authority);
return new UserUsernamePasswordAuthenticationToken(username, password, authorityList);
}
return null;
}
@Override
public boolean supports(Class<?> authentication)
{
return authentication.equals(AdminUsernamePasswordAuthenticationToken.class);
}
}
CustomAuthentictionProvider - 对于用户
@Component
public class UserCustomAuthenticationProvider implements AuthenticationProvider
{
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException
{
String username = authentication.getName();
String password = authentication.getCredentials().toString();
if (username.equals("user") && password.equals("user@123#"))
{
List<GrantedAuthority> authorityList = new ArrayList<>();
GrantedAuthority authority = new SimpleGrantedAuthority("ROLE_USER");
authorityList.add(authority);
return new UserUsernamePasswordAuthenticationToken(username, password, authorityList);
}
return null;
}
@Override
public boolean supports(Class<?> authentication)
{
return authentication.equals(UserUsernamePasswordAuthenticationToken.class);
}
}
CustomFilter 所需的 CustomHandlers
@Component
public class CustomAuthenticationFailureHandler implements AuthenticationFailureHandler
{
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException
{
response.sendRedirect(request.getContextPath() + "/login?error=true");
}
}
@Component
public class CustomAuthenticationSuccessHandler implements AuthenticationSuccessHandler
{
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException
{
HttpSession session = request.getSession();
if (session != null)
{
session.removeAttribute(WebAttributes.AUTHENTICATION_EXCEPTION);
}
response.sendRedirect(request.getContextPath() + "/app/user/dashboard");
}
}
最后 SpringSecurityConfiguration
@Configuration
@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter
{
@Autowired
DataSource dataSource;
@Autowired
private AdminCustomAuthenticationProvider adminCustomAuthenticationProvider;
@Autowired
private UserCustomAuthenticationProvider userCustomAuthenticationProvider;
@Autowired
private CustomAuthenticationSuccessHandler customAuthenticationSuccessHandler;
@Autowired
private CustomAuthenticationFailureHandler customAuthenticationFailureHandler;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception
{
auth.authenticationProvider(adminCustomAuthenticationProvider);
auth.authenticationProvider(userCustomAuthenticationProvider);
}
@Bean
public MyAuthenticationFilter myAuthenticationFilter() throws Exception
{
MyAuthenticationFilter authenticationFilter = new MyAuthenticationFilter();
authenticationFilter.setAuthenticationSuccessHandler(customAuthenticationSuccessHandler);
authenticationFilter.setAuthenticationFailureHandler(customAuthenticationFailureHandler);
authenticationFilter.setRequiresAuthenticationRequestMatcher(new AntPathRequestMatcher("/login", "POST"));
authenticationFilter.setAuthenticationManager(authenticationManagerBean());
return authenticationFilter;
}
@Override
protected void configure(final HttpSecurity http) throws Exception
{
http
.addFilterBefore(myAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
.csrf().disable()
.authorizeRequests()
.antMatchers("/resources/**", "/", "/login")
.permitAll()
.antMatchers("/config/*", "/app/admin/*")
.hasRole("ADMIN")
.antMatchers("/app/user/*")
.hasAnyRole("ADMIN", "USER")
.antMatchers("/api/**")
.hasRole("APIUSER")
.and().exceptionHandling()
.accessDeniedPage("/403")
.and().logout()
.logoutSuccessHandler(new CustomLogoutSuccessHandler())
.invalidateHttpSession(true);
http.sessionManagement().maximumSessions(1).expiredUrl("/login?expired=true");
}
}
希望它有助于理解在没有回退身份验证的情况下配置多重身份验证。
关于java - 具有不同 UsernamePasswordAuthToken 的多个 AuthenticationProvider 可以在没有回退身份验证的情况下对不同的登录表单进行身份验证,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/57881749/
