spring security+oauth2的SSO方案

springboot项目加入spring security其实是很简单的事情，主要就是config方法的重写。

### 客户端 ###

<table> 
 <tbody> 
  <tr> 
   <td> <pre><code>@EnableOAuth2Sso
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http.antMatcher("/**")
                .authorizeRequests()
                .antMatchers("/updateResult**","/getOneAccount**","/login**")
                .permitAll()
                .anyRequest()
                .authenticated();
    }
}
</code></pre> </td> 
  </tr> 
 </tbody> 
</table>

login在校验oauth服务器的时候要用到，所以这里需要放行。注解`@EnableOAuth2Sso`就是开启客户端sso

springboot的配置文件中增加对oauth校验服务器的访问配置

<table> 
 <tbody> 
  <tr> 
   <td> <pre><code>#security
security.oauth2.client.client-id=SampleClientId
security.oauth2.client.client-secret=secret
security.oauth2.client.access-token-uri=http://localhost:8081/auth/oauth/token
security.oauth2.client.user-authorization-uri=http://localhost:8081/auth/oauth/authorize

security.oauth2.resource.user-info-uri=http://localhost:8081/auth/user/me
</code></pre> </td> 
  </tr> 
 </tbody> 
</table>

### 授权层 ###

<table> 
 <tbody> 
  <tr> 
   <td> <pre><code>@Configuration
@EnableAuthorizationServer
public class AuthServerConfig extends AuthorizationServerConfigurerAdapter {
    
    @Resource
    private BCryptPasswordEncoder passwordEncoder;
    
    @Override
    public void configure(final AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer.tokenKeyAccess("permitAll()")
            .checkTokenAccess("isAuthenticated()");
    }

@Override
    public void configure(final ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
            .withClient("SampleClientId")
            .secret(passwordEncoder.encode("secret"))
            .authorizedGrantTypes("authorization_code")
            .scopes("user_info")
            .autoApprove(true)
            .redirectUris("http://localhost:8848/login","http://localhost:8849/login","http://localhost:8850/login","http://localhost:8082/ui/login","http://localhost:8083/ui2/login","http://localhost:8082/login","http://www.example.com/")
        // .accessTokenValiditySeconds(3600)
        ; // 1 hour
    }

}
</code></pre> </td> 
  </tr> 
 </tbody> 
</table>

有验证服务器当然是授权码模式，redirectUris中加入所有重定向的地址，也就是客户端的url，因为通过验证服务器成功后需要重定向到客户端。

接下来就是SecurityConfig的配置

<table> 
 <tbody> 
  <tr> 
   <td> <pre><code>@Configuration
@Order(1)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    
    @Override
    protected void configure(HttpSecurity http) throws Exception { // @formatter:off
        http.requestMatchers()
            .antMatchers("/login", "/oauth/authorize")
            .and()
            .authorizeRequests()
            .anyRequest()
            .authenticated()
            .and()
            .formLogin()
            .permitAll()
            .and().csrf().disable();
    } // @formatter:on

@Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception { // @formatter:off
        auth.inMemoryAuthentication()
            .withUser("admin")
            .password(passwordEncoder().encode("admin"))
            .roles("USER");
    } // @formatter:on

@Bean
    public BCryptPasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }
}
</code></pre> </td> 
  </tr> 
 </tbody> 
</table>

@Order(1)因为上一个文件中用到了这里的ECryptPasswordEncoder，所以这里要优先装配。`/oauth/authorize`是oauth默认的校验地址。
