類似于spring security的xml配置文件命名空間配置中的<http>元素。它允許對特定的http請求基于安全考慮進(jìn)行配置。默認(rèn)情況下,適用于所有的請求,但可以使用requestMatcher(RequestMatcher)或者其它相似的方法進(jìn)行限制。

使用示例:

最基本的基于表單的配置如下。該配置將所有的url訪問權(quán)限設(shè)定為角色名稱為"ROLE_USER".同時也定義了內(nèi)存認(rèn)證模式:使用用戶名"user"和密碼“password”,角色"ROLE_USER"來認(rèn)證。

 @Configuration
 @EnableWebSecurity
 public class FormLoginSecurityConfig extends WebSecurityConfigurerAdapter {
 
  @Override
  protected void configure(HttpSecurity http) throws Exception {
   http
    .authorizeRequests()
     .antMatchers("/").hasRole("USER")
     .and()
    .formLogin();
  }
 
  @Override
  protected void configure(AuthenticationManagerBuilder auth) throws Exception {
   auth
    .inMemoryAuthentication()
     .withUser("user")
       .password("password")
       .roles("USER");
  }
 }

 配置基于openId的認(rèn)證方式

 basic示例,不使用attribute exchange

    @Configuration
  @EnableWebSecurity
  public class OpenIDLoginConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) {
    http
     .authorizeRequests()
      .antMatchers("/").hasRole("USER")
      .and()
     .openidLogin()
      .permitAll();
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth
      .inMemoryAuthentication()
       // the username must match the OpenID of the user you are
       // logging in with
       .withUser("https://www.google.com/accounts/o8/id?id=lmkCn9xzPdsxVwG7pjYMuDgNNdASFmobNkcRPaWU")
        .password("password")
        .roles("USER");
   }
  }

下面展示一個更高級的示例,使用attribute exchange

  @Configuration
  @EnableWebSecurity
  public class OpenIDLoginConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) {
    http
     .authorizeRequests()
      .antMatchers("/").hasRole("USER")
      .and()
     .openidLogin()
      .loginPage("/login")
      .permitAll()
      .authenticationUserDetailsService(new AutoProvisioningUserDetailsService())
       .attributeExchange("https://www.google.com/.")
        .attribute("email")
         .type("http://axschema.org/contact/email")
         .required(true)
         .and()
        .attribute("firstname")
         .type("http://axschema.org/namePerson/first")
         .required(true)
         .and()
        .attribute("lastname")
         .type("http://axschema.org/namePerson/last")
         .required(true)
         .and()
        .and()
       .attributeExchange(".yahoo.com.")
        .attribute("email")
         .type("http://schema.openid.net/contact/email")
         .required(true)
         .and()
        .attribute("fullname")
         .type("http://axschema.org/namePerson")
         .required(true)
         .and()
        .and()
       .attributeExchange(".myopenid.com.")
        .attribute("email")
         .type("http://schema.openid.net/contact/email")
         .required(true)
         .and()
        .attribute("fullname")
         .type("http://schema.openid.net/namePerson")
         .required(true);
   }
  }
  
  public class AutoProvisioningUserDetailsService implements
    AuthenticationUserDetailsService&lt;OpenIDAuthenticationToken&gt; {
   public UserDetails loadUserDetails(OpenIDAuthenticationToken token) throws UsernameNotFoundException {
    return new User(token.getName(), "NOTUSED", AuthorityUtils.createAuthorityList("ROLE_USER"));
   }
  }

增加響應(yīng)安全報文頭

默認(rèn)情況下當(dāng)使用WebSecuirtyConfigAdapter的默認(rèn)構(gòu)造函數(shù)時激活。

僅觸發(fā)Headers()方法而不觸發(fā)其它方法或者接受WebSecurityConfigureerAdater默認(rèn)的,等同于:

@Configuration
  @EnableWebSecurity
  public class CsrfSecurityConfig extends WebSecurityConfigurerAdapter {
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .headers()
      .contentTypeOptions();
      .xssProtection()
      .cacheControl()
      .httpStrictTransportSecurity()
      .frameOptions()
      .and()
     ...;
   }
  }

取消安全報文頭,如下:

  @Configuration
  @EnableWebSecurity
  public class CsrfSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .headers().disable()
     ...;
   }
  }

使用部分安全報文頭

觸發(fā)headers()方法的返回結(jié)果,例如,只使用HeaderConfigurer的cacheControll()方法和HeadersConfigurer的frameOptions()方法.

  @Configuration
  @EnableWebSecurity
  public class CsrfSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .headers()
      .cacheControl()
      .frameOptions()
      .and()
     ...;
   }
  }

配置session管理

下面的配置展示了只允許認(rèn)證用戶在同一時間只有一個實例是如何配置的。若一個用戶使用用戶名為"user"認(rèn)證并且沒有退出,同一個名為“user”的試圖再次認(rèn)證時,第一個用戶的session將會強(qiáng)制銷毀,并設(shè)置到"/login?expired"的url。

  @Configuration
  @EnableWebSecurity
  public class SessionManagementSecurityConfig extends
    WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .anyRequest().hasRole("USER")
      .and()
     .formLogin()
      .permitAll()
      .and()
     .sessionManagement()
      .maximumSessions(1)
      .expiredUrl("/login?expired");
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth.
     inMemoryAuthentication()
      .withUser("user")
       .password("password")
       .roles("USER");
   }
  }

當(dāng)使用SessionManagementConfigurer的maximumSessio(int)時不用忘記為應(yīng)用配置HttpSessionEventPublisher,這樣能保證過期的session能夠被清除。

在web.xml中可以這樣配置:

  <listener>
   <listener-class>org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>;
  </listener>

配置PortMapper

允許配置一個從HttpSecurity的getSharedObject(Class)方法中獲取的PortMapper。當(dāng)http請求跳轉(zhuǎn)到https或者h(yuǎn)ttps請求跳轉(zhuǎn)到http請求時(例如我們和requiresChanenl一起使用時),別的提供的SecurityConfigurer對象使用P誒賬戶的PortMapper作為默認(rèn)的PortMapper。默認(rèn)情況下,spring security使用PortMapperImpl來映射http端口8080到https端口8443,并且將http端口的80映射到https的端口443.

配置示例如下,下面的配置將確保在spring security中的http請求端口9090跳轉(zhuǎn)到https端口9443 并且將http端口80跳轉(zhuǎn)到https443端口。

  @Configuration
  @EnableWebSecurity
  public class PortMapperSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/").hasRole("USER")
      .and()
     .formLogin()
      .permitAll()
      .and()
      // Example portMapper() configuration
      .portMapper()
       .http(9090).mapsTo(9443)
       .http(80).mapsTo(443);
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
       .password("password")
       .roles("USER");
   }
  }

配置基于容器的預(yù)認(rèn)證

在這個場景中,servlet容器管理認(rèn)證。

配置示例:

下面的配置使用HttpServletRequest中的principal,若用戶的角色是“ROLE_USER”或者"ROLE_ADMIN",將會返回Authentication結(jié)果。

 @Configuration
  @EnableWebSecurity
  public class JeeSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/").hasRole("USER")
      .and()
     // Example jee() configuration
     .jee()
      .mappableRoles("ROLE_USER", "ROLE_ADMIN");
   }
  }

開發(fā)者希望使用基于容器預(yù)認(rèn)證時,需要在web.xml中配置安全限制。例如:

 <login-config>
   <auth-method>FORM</auth-method>
   <form-login-config>
    <form-login-page>/login</form-login-page>
    <form-error-page>/login?error</form-error-page>
   </form-login-config>
  </login-config>
  
  <security-role>
   <role-name>ROLE_USER</role-name>
  </security-role>
  <security-constraint>
   <web-resource-collection>
   <web-resource-name>Public</web-resource-name>
    <description>Matches unconstrained pages</description>
    <url-pattern>/login</url-pattern>
    <url-pattern>/logout</url-pattern>
    <url-pattern>/resources/</url-pattern>
   </web-resource-collection>
  </security-constraint>
  <security-constraint>
   <web-resource-collection>
    <web-resource-name>Secured Areas</web-resource-name>
    <url-pattern>/</url-pattern>
   </web-resource-collection>
   <auth-constraint>
    <role-name>ROLE_USER</role-name>
   </auth-constraint>
  </security-constraint>

配置基于X509的預(yù)認(rèn)證

配置示例,下面的配置試圖從X509證書中提取用戶名,注意,為完成這個工作,客戶端請求證書需要配置到servlet容器中。

  @Configuration
  @EnableWebSecurity
  public class X509SecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/").hasRole("USER")
      .and()
     // Example x509() configuration
     .x509();
   }
  }

配置Remember-me服務(wù)

配置示例,下面的配置展示了如何允許基于token的remember-me的認(rèn)證。若http參數(shù)中包含一個名為“remember-me”的參數(shù),不管session是否過期,用戶記錄將會被記保存下來。

 @Configuration
  @EnableWebSecurity
  public class RememberMeSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
        .password("password")
        .roles("USER");
   }
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/").hasRole("USER")
      .and()
     .formLogin()
      .permitAll()
      .and()
     // Example Remember Me Configuration
     .rememberMe();
   }
  }

限制HttpServletRequest的請求訪問

配置示例,最基本的示例是配置所有的url訪問都需要角色"ROLE_USER".下面的配置要求每一個url的訪問都需要認(rèn)證,并且授權(quán)訪問權(quán)限給用戶"admin"和"user".

@Configuration
  @EnableWebSecurity
  public class AuthorizeUrlsSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/").hasRole("USER")
      .and()
     .formLogin();
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
        .password("password")
        .roles("USER")
        .and()
      .withUser("adminr")
        .password("password")
        .roles("ADMIN","USER");
   }
  }

同樣,也可以配置多個url。下面的配置要求以/admin/開始的url訪問權(quán)限為“admin”用戶。

@Configuration
  @EnableWebSecurity
  public class AuthorizeUrlsSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/admin/**").hasRole("ADMIN")
      .antMatchers("/**").hasRole("USER")
      .and()
     .formLogin();
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
        .password("password")
        .roles("USER")
        .and()
      .withUser("adminr")
        .password("password")
        .roles("ADMIN","USER");
   }
  }

注意:匹配起效是按照順序來的。因此如果下面的配置是無效的,因為滿足第一個規(guī)則后將不會檢查第二條規(guī)則:

  http
   .authorizeRequests()
    .antMatchers("/**").hasRole("USER")
    .antMatchers("/admin/**").hasRole("ADMIN")

增加CSRF支持

默認(rèn)情況下,當(dāng)使用WebSecurityConfigurerAdapter時的默認(rèn)構(gòu)造方法時CSRF是激活的。你可以使用如下方法關(guān)閉它:

  @Configuration
  @EnableWebSecurity
  public class CsrfSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .csrf().disable()
     ...;
   }
  }

增加logout支持

默認(rèn)支持,當(dāng)使用WebSecurityConfigurerAdapter時Logout是支持的。當(dāng)用戶發(fā)出“/logout”請求時,系統(tǒng)將會銷毀session并且清空配置的rememberMe()認(rèn)證,然后清除SecurityContextHolder,最后跳向logout成功頁面或者登陸頁面。

 @Configuration
  @EnableWebSecurity
  public class LogoutSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/").hasRole("USER")
      .and()
     .formLogin()
      .and()
     // sample logout customization
     .logout()
      .logout()
       .deleteCookies("remove")
       .invalidateHttpSession(false)
       .logoutUrl("/custom-logout")
       .logoutSuccessUrl("/logout-success");
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
        .password("password")
        .roles("USER");
   }
  }

匿名用戶控制

使用WebSecurityConfigurerAdapter時自動綁定。默認(rèn)情況下,匿名用戶有一個AnonymousAuthenticationToken標(biāo)示,包含角色"ROLE_ANONYMOUS"。

下面的配置展示了如何指定匿名用戶應(yīng)該包含"ROLE_ANON".

    @Configuration
  @EnableWebSecurity
  public class AnononymousSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/").hasRole("USER")
      .and()
     .formLogin()
      .and()
     // sample anonymous customization
     .anonymous()
      .authorities("ROLE_ANON");
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
        .password("password")
        .roles("USER");
   }
  }

基于表單的認(rèn)證

若FormLoginConfigurer的loginpage(String)沒有指定,將會產(chǎn)生一個默認(rèn)的login頁面。

示例配置:

@Configuration
  @EnableWebSecurity
  public class FormLoginSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/**").hasRole("USER")
      .and()
     .formLogin();
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
        .password("password")
        .roles("USER");
   }
  }

下面的示例展示了自定義的表單認(rèn)證:

 @Configuration
  @EnableWebSecurity
  public class FormLoginSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/").hasRole("USER")
      .and()
     .formLogin()
       .usernameParameter("j_username") // default is username
       .passwordParameter("j_password") // default is password
       .loginPage("/authentication/login") // default is /login with an HTTP get
       .failureUrl("/authentication/login?failed") // default is /login?error
       .loginProcessingUrl("/authentication/login/process"); // default is /login with an HTTP post
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
        .password("password")
        .roles("USER");
   }
  }

配置安全通道

為使配置生效,需至少配置一個通道的映射。

配置示例:

下面例子展示了如何將每個請求都使用https通道。

 @Configuration
  @EnableWebSecurity
  public class ChannelSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/**").hasRole("USER")
      .and()
     .formLogin()
      .and()
     .channelSecurity()
      .anyRequest().requiresSecure();
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
        .password("password")
        .roles("USER");
   }
  }

配置http 基本認(rèn)證

配置示例:

 @Configuration
  @EnableWebSecurity
  public class HttpBasicSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .authorizeRequests()
      .antMatchers("/**").hasRole("USER").and()
      .httpBasic();
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
       .password("password")
       .roles("USER");
   }
  }

配置要觸發(fā)的HttpRequest

重寫RequestMatcher方法、antMatcher()z、regexMatcher()等。

配置示例

下面的配置使HttpSecurity接收以"/api/","/oauth/"開頭請求。

 @Configuration
  @EnableWebSecurity
  public class RequestMatchersSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .requestMatchers()
      .antMatchers("/api/**","/oauth/**")
      .and()
     .authorizeRequests()
      .antMatchers("/**").hasRole("USER").and()
      .httpBasic();
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
       .password("password")
       .roles("USER");
   }
  }

下面的配置和上面的相同:

@Configuration
  @EnableWebSecurity
  public class RequestMatchersSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .requestMatchers()
      .antMatchers("/api/**")
      .antMatchers("/oauth/**")
      .and()
     .authorizeRequests()
      .antMatchers("/**").hasRole("USER").and()
      .httpBasic();
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
       .password("password")
       .roles("USER");
   }
  }

同樣也可以這樣使用:

@Configuration
  @EnableWebSecurity
  public class RequestMatchersSecurityConfig extends WebSecurityConfigurerAdapter {
  
   @Override
   protected void configure(HttpSecurity http) throws Exception {
    http
     .requestMatchers()
      .antMatchers("/api/**")
      .and()
     .requestMatchers()
      .antMatchers("/oauth/**")
      .and()
     .authorizeRequests()
      .antMatchers("/**").hasRole("USER").and()
      .httpBasic();
   }
  
   @Override
   protected void configure(AuthenticationManagerBuilder auth)
     throws Exception {
    auth
     .inMemoryAuthentication()
      .withUser("user")
       .password("password")
       .roles("USER");
   }
  }
