Spring Security oAuth2

Spring Security

Spring Security 是一个spring的安全框架

oAuth2

是一种授权协议，他的主要作用是为了提供认证和授权的标准

Access Token

客户端访问资源服务器的令牌，代表用户的授权

Refresh Token

刷新令牌，是用来实现安全令牌的时效机制，使通过安全令牌访问的资源更加安全

配置认证服务器

在云服务中一般有认证服务器和资源服务器，通常认证服务器用来获取用户的登录和授权信息，而资源服务器则用来校验具体的权限信息

认证服务器注解

@Configuration
@EnableAuthorizationServer

认证服务器继承类

认证服务器继承AuthorizationServerConfigurerAdapter
认证服务器通过客户端的id,密钥，客户端授权类型取得客户端授权范围

资源服务代码示例

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.InMemoryTokenStore;

/**
 * @author admin
 * @version v1.0.0
 **/
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private BCryptPasswordEncoder passwordEncoder;

    @Autowired
    private AuthenticationManager authenticationManager;
    // 增加 TokenStore 配置
    @Bean
    public TokenStore tokenStore() {
        return new InMemoryTokenStore();
    }
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints
                .authenticationManager(authenticationManager)
                // 增加 TokenStore 配置
                .tokenStore(tokenStore());
    }
    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security
                .checkTokenAccess("isAuthenticated()")
                .allowFormAuthenticationForClients();
    }
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients
                .inMemory()
                .withClient("client")
                .secret(passwordEncoder.encode("secret"))
                .authorizedGrantTypes("password", "refresh_token")
                .scopes("backend")
                .resourceIds("backend-resources")
                .accessTokenValiditySeconds(60 * 60 * 24)
                .refreshTokenValiditySeconds(60 * 60 * 24 * 30);
    }
}

服务器安全配置

创建一个类继承 WebSecurityConfigurerAdapter 并添加相关注解(@Configuration @EnableWebSecurity @EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)
)

服务器安全配置代码示例

/**
 * @author admin
 * @version v1.0.0
 **/
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        // 设置默认的加密方式
        return new BCryptPasswordEncoder();
    }

    @Bean
    @Override
    protected UserDetailsService userDetailsService() {
        return new UserDetailsServiceImpl();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        // 使用自定义认证与授权
        auth.userDetailsService(userDetailsService());
    }

    @Override
    public void configure(WebSecurity web){
        web.ignoring().antMatchers("/user/login").antMatchers("/user/logout");
/*                .antMatchers("/oauth/authorize")
                .antMatchers("/oauth/check_token");*/

    }

    /**
     * 用于支持 password 模式
     *
     * @return
     * @throws Exception
     */
    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.exceptionHandling()
                .and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .authorizeRequests()
                // 增加了授权访问配置,正常用户都可以注销
                .antMatchers("/user/logout").hasAuthority("USER");
    }
}

配置资源服务器

资源服务器则用来校验具体的权限信息

资源服务器注解

@Configuration
@EnableResourceServer
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)

资源服务器继承类

资源服务器继承ResourceServerConfigurerAdapter
资源服务器通声明自身资源ID和需要的角色权限

资源服务器代码示例

@Configuration
@EnableResourceServer
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
                .exceptionHandling()
                .and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .authorizeRequests()
                .antMatchers("/**").hasAuthority("USER");
    }
    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
        // 配置资源 ID
        resources.resourceId("backend-resources");
    }
}
