spring security

spring boot 整合 security

org.springframework.security.core.userdetails.User
org.springframework.security.core.userdetails.UserDetails

1 . 实现UserDetailsService的loadUserByUsername方法,作用是从数据库获取用户信息

//给自定义认证方式添加加密方式，在userDetailsService将密码交给security去验证，在认证管理中配置密码验证方式
@Override public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
  return new User(userInfo.getAccount(), userInfo.getPassword(), roles);
}

2 . 实现AuthenticationProvider的authenticate方法根据UserDetails实现类获取用户信息进行用户密码，状态等相关验证

3 . 告诉security认证方式

  /**
 * 添加自定义登录到认证security管理
 * 
 */
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
  //用户认证逻辑
  auth.authenticationProvider(userAuthenticationProvider)
  		//获取用户信息
      .userDetailsService(userDetailsService)
      //密码加密方式
      .passwordEncoder(passwordEncoder());
}

4 . 访问资源控制,http.authorizeRequests()方法有多个子节点，每个macher按照他们的声明顺序执行,路径配置顺序有要求 ，匹配就返回. hasAnyAuthority("USER")需要有USER权限才能访问； hasAnyRole("ADMIN")会自动给ADMIN加上**ROLE_**前缀，需要有ROLE_ADMIN角色才能访问。

/**
     * security 拦截路径
     * http.authorizeRequests()方法有多个子节点，每个macher按照他们的声明顺序执行
     * 路径配置顺序有要求 ，匹配就返回
     *
     * @param http
     * @throws Exception
     */
    @Override protected void configure(HttpSecurity http) throws Exception {
      http.csrf().disable()
          .authorizeRequests()
          .antMatchers("/security/login/**").permitAll()
          .antMatchers("/security/user/**").hasAnyAuthority("USER")
          .antMatchers("/security/role/**").hasAnyRole("ADMIN")
          .anyRequest().authenticated()
          .and()
          .rememberMe()
          .key("my-secret")
          .rememberMeCookieName("my-cookie-name")
          .tokenValiditySeconds(24 * 60 * 60)
          .and()
          .formLogin()
          .and()
          .logout()
          .and()
          .httpBasic()
      ;
      // 在 UsernamePasswordAuthenticationFilter 前添加自定义过滤器 BeforeLoginFilter 
      http.addFilterBefore(new BeforeLoginFilter(), UsernamePasswordAuthenticationFilter.class);
    }

整合oauth2

oauth2-security区分了客户端和用户。

5 . 实现ClientDetailsService的loadClientByClientId方法，实现客户端认证

6 . 配置认证server（@EnableAuthorizationServer）通过继承AuthorizationServerConfigurerAdapter配置认证oauth2自定义客户端和用户认证

//client认证
@Override
  public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    clients.withClientDetails(clientDetailsService);
  }

  @Override
  public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
    endpoints
    		//token存储位置
        .tokenStore(new InMemoryTokenStore())
        //将web security配置的authenticationManager
        .authenticationManager(authenticationManager)
        //刷新token会用到userDetailsService
        .userDetailsService(userDetailsService)
        .allowedTokenEndpointRequestMethods(HttpMethod.GET, HttpMethod.POST);
  }

  @Override
  public void configure(AuthorizationServerSecurityConfigurer oauthServer) {
  	//允许验证token 接口访问,单点登录会访问这个接口验证token是否有效
    oauthServer.checkTokenAccess("permitAll()");
    //加密方式
    oauthServer.passwordEncoder(passwordEncoder());
    //允许表单认证
    oauthServer.allowFormAuthenticationForClients();
  }

7 . 修改security的资源控制,不拦截oauth2资源

@Override protected void configure(HttpSecurity http) throws Exception {
      http
          .authorizeRequests()
          .antMatchers("/oauth/*").permitAll()
          .and().httpBasic()
      ;
    }
    
   /**
      * 在这security中，把AuthenticationManager交给Spring，
      * 这一步的配置是必不可少的，否则SpringBoot会自动配置一个AuthenticationManager,覆盖掉内存中的用户
      */
     @Bean
     @Override
     public AuthenticationManager authenticationManagerBean() throws Exception {
       AuthenticationManager manager = super.authenticationManagerBean();
       return manager;
     }

8 . 配置资源server（@EnableResourceServer） 继承ResourceServerConfigurerAdapter配置oauth2资源控制

@Configuration
@EnableResourceServer
class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {

  @Override
  public void configure(ResourceServerSecurityConfigurer resources) {
    //资源id和loadClientByClientId查询到的相匹配
    resources.resourceId("API");
  }

  @Override
  public void configure(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
        //必须认证过后才可以访问
        .antMatchers("/security/user/**").hasAnyAuthority("USER")
        .antMatchers("/security/role/**").hasAnyRole("ADMIN")
        .anyRequest().permitAll()
    ;
  }
}
/**
 * oauth2 几种获取token方式 client 可用basic 方式传递
 * refresh token: http://localhost:8013/oauth/token?grant_type=refresh_token&refresh_token=3680e51e-fbf4-417a-85d9-6a8205c14c0a&client_id=user&client_secret=123456
 * client: http://localhost:8013/oauth/token?client_id=user&client_secret=123456&scope=read&grant_type=client_credentials
 * password: http://localhost:8013/oauth/token?username=zhangsan&password=123456&grant_type=password&scope=read&client_id=user&client_secret=1234567
 * authorization code: http://localhost:8013/oauth/authorize?response_type=code&client_id=code&redirect_uri=http://localhost:8013/security/login&scope=all
