# 需求背景 #

> 本篇文章讲解如何通过Springboot2集成验证服务JWT Token，以及资源服务的用法（[更多官方关于 Oauth2][Oauth2]）

此篇在《[Oauth2+Token详细用法/SpringSecurity][Oauth2_Token_SpringSecurity]》基础上修改而来，可先去阅读此篇文章

> 以下内容：主要是讲解用法差异的地方

# OAuth2术语 #

*  JWT
    
     *  JSON Web Token 身份令牌

# Oauth2 密码授权流程 #

在oauth2协议中，一个应用会有自己的clientId和clientSecret（从认证方申请），由认证方下发clientId和secret

> 授权服务 Authorization Server

构建Authorization Server，这里我使用了SpringSecurity5 和 SpringBoot 2.0.6版本

**1. 项目目录结构**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9oZW1pbi5ibG9nLmNzZG4ubmV0_size_16_color_FFFFFF_t_70 1][]

Spring Security Configuration 部分

**2. SecurityProperties.java文件**

先使用注解`@ConfigurationProperties，绑定配置文件（后面会看到）`

package com.md.demo.oauth.jwt.config.props;
    
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.core.io.Resource;
    
    @ConfigurationProperties("security")
    public class SecurityProperties {
    
        private JwtProperties jwt;
    
        public JwtProperties getJwt() {
            return jwt;
        }
    
        public void setJwt(JwtProperties jwt) {
            this.jwt = jwt;
        }
    
        public static class JwtProperties {
    
            private Resource keyStore;
            private String keyStorePassword;
            private String keyPairAlias;
            private String keyPairPassword;
    
            public Resource getKeyStore() {
                return keyStore;
            }
    
            public void setKeyStore(Resource keyStore) {
                this.keyStore = keyStore;
            }
    
            public String getKeyStorePassword() {
                return keyStorePassword;
            }
    
            public void setKeyStorePassword(String keyStorePassword) {
                this.keyStorePassword = keyStorePassword;
            }
    
            public String getKeyPairAlias() {
                return keyPairAlias;
            }
    
            public void setKeyPairAlias(String keyPairAlias) {
                this.keyPairAlias = keyPairAlias;
            }
    
            public String getKeyPairPassword() {
                return keyPairPassword;
            }
    
            public void setKeyPairPassword(String keyPairPassword) {
                this.keyPairPassword = keyPairPassword;
            }
        }
    }

**3. AuthorizationServerConfiguration.java文件**

此类中，你会看到所有JWT需要Spring的@Bean注解，其中最重要的是：JwtAccessTokenConverter, JwtTokenStore and the DefaultTokenServices

package com.md.demo.oauth.jwt.config.security;
    
    import java.security.KeyPair;
    
    import javax.sql.DataSource;
    
    import org.springframework.boot.context.properties.EnableConfigurationProperties;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.security.authentication.AuthenticationManager;
    import org.springframework.security.core.userdetails.UserDetailsService;
    import org.springframework.security.crypto.password.PasswordEncoder;
    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.ClientDetailsService;
    import org.springframework.security.oauth2.provider.token.DefaultTokenServices;
    import org.springframework.security.oauth2.provider.token.TokenStore;
    import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
    import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;
    import org.springframework.security.oauth2.provider.token.store.KeyStoreKeyFactory;
    
    import com.md.demo.oauth.jwt.config.props.SecurityProperties;
    
    @Configuration
    @EnableAuthorizationServer
    @EnableConfigurationProperties(SecurityProperties.class)
    public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {
    
        private final DataSource dataSource;
        private final PasswordEncoder passwordEncoder;
        private final AuthenticationManager authenticationManager;
        private final SecurityProperties securityProperties;
        private final UserDetailsService userDetailsService;
    
        private JwtAccessTokenConverter jwtAccessTokenConverter;
        private TokenStore tokenStore;
    
        public AuthorizationServerConfiguration(final DataSource dataSource, final PasswordEncoder passwordEncoder,
                                                final AuthenticationManager authenticationManager, final SecurityProperties securityProperties,
                                                final UserDetailsService userDetailsService) {
            this.dataSource = dataSource;
            this.passwordEncoder = passwordEncoder;
            this.authenticationManager = authenticationManager;
            this.securityProperties = securityProperties;
            this.userDetailsService = userDetailsService;
        }
    
        @Bean
        public TokenStore tokenStore() {
            if (tokenStore == null) {
                tokenStore = new JwtTokenStore(jwtAccessTokenConverter());
            }
            return tokenStore;
        }
    
        @Bean
        public DefaultTokenServices tokenServices(final TokenStore tokenStore,
                                                  final ClientDetailsService clientDetailsService) {
            DefaultTokenServices tokenServices = new DefaultTokenServices();
            tokenServices.setSupportRefreshToken(true);
            tokenServices.setTokenStore(tokenStore);
            tokenServices.setClientDetailsService(clientDetailsService);
            tokenServices.setAuthenticationManager(this.authenticationManager);
            return tokenServices;
        }
    
        @Bean
        public JwtAccessTokenConverter jwtAccessTokenConverter() {
            if (jwtAccessTokenConverter != null) {
                return jwtAccessTokenConverter;
            }
    
            SecurityProperties.JwtProperties jwtProperties = securityProperties.getJwt();
            KeyPair keyPair = keyPair(jwtProperties, keyStoreKeyFactory(jwtProperties));
    
            jwtAccessTokenConverter = new JwtAccessTokenConverter();
            jwtAccessTokenConverter.setKeyPair(keyPair);
            return jwtAccessTokenConverter;
        }
    
        @Override
        public void configure(final ClientDetailsServiceConfigurer clients) throws Exception {
            clients.jdbc(this.dataSource);
        }
    
        @Override
        public void configure(final AuthorizationServerEndpointsConfigurer endpoints) {
            endpoints.authenticationManager(this.authenticationManager)
                    .accessTokenConverter(jwtAccessTokenConverter())
                    .userDetailsService(this.userDetailsService)
                    .tokenStore(tokenStore());
        }
    
        @Override
        public void configure(final AuthorizationServerSecurityConfigurer oauthServer) {
            oauthServer.passwordEncoder(this.passwordEncoder).tokenKeyAccess("permitAll()")
                    .checkTokenAccess("isAuthenticated()");
        }
    
        private KeyPair keyPair(SecurityProperties.JwtProperties jwtProperties, KeyStoreKeyFactory keyStoreKeyFactory) {
            return keyStoreKeyFactory.getKeyPair(jwtProperties.getKeyPairAlias(), jwtProperties.getKeyPairPassword().toCharArray());
        }
    
        private KeyStoreKeyFactory keyStoreKeyFactory(SecurityProperties.JwtProperties jwtProperties) {
            return new KeyStoreKeyFactory(jwtProperties.getKeyStore(), jwtProperties.getKeyStorePassword().toCharArray());
        }
    }

**4. application.yml文件**

当你生成自己的签名证书后，配置如下

server:
      port: 9000
    
    security:
      jwt:
        key-store: classpath:keystore.jks
        key-store-password: letmein
        key-pair-alias: mytestkey
        key-pair-password: changeme
    
    spring:
      jackson:
        serialization:
          INDENT_OUTPUT: true

> 资源服务 Resource Server

**1. 项目目录结构**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9oZW1pbi5ibG9nLmNzZG4ubmV0_size_16_color_FFFFFF_t_70 2][]

**2. SecurityProperties.java文件**

为了解码JWT token，我们将要使用在生成自己的签名证书时的public key

在此之前，我们需要先通过@`ConfigurationProperties注解绑定到配置文件`

package com.md.demo.oauth.jwt.ds.config;
    
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.core.io.Resource;
    
    @ConfigurationProperties("security")
    public class SecurityProperties {
    
        private JwtProperties jwt;
    
        public JwtProperties getJwt() {
            return jwt;
        }
    
        public void setJwt(JwtProperties jwt) {
            this.jwt = jwt;
        }
    
        public static class JwtProperties {
    
            private Resource publicKey;
    
            public Resource getPublicKey() {
                return publicKey;
            }
    
            public void setPublicKey(Resource publicKey) {
                this.publicKey = publicKey;
            }
        }
    
    }

使用下面的命令，导出public key

$ keytool -list -rfc --keystore keystore.jks | openssl x509 -inform pem -pubkey -noout

案例结果如下：

把内容复制到public.txt文件中，然后配置到application.yml文件中

**3. application.yml配置**

server:
      port: 9100
    
    security:
      jwt:
        public-key: classpath:public.txt
    
    spring:
      jackson:
        serialization:
          INDENT_OUTPUT: true

**4. ResourceServerConfiguration.java文件**

用法同AuthorizationServerConfiguration.java文件解释，不重复解释了，可见上面解释

package com.md.demo.oauth.jwt.ds.config;
    
    import static java.nio.charset.StandardCharsets.UTF_8;
    
    import java.io.IOException;

    import org.springframework.security.oauth2.provider.token.DefaultTokenServices;
    import org.springframework.security.oauth2.provider.token.TokenStore;
    import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
    import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;
    
    @Configuration
    @EnableResourceServer
    @EnableConfigurationProperties(SecurityProperties.class)
    public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {
    
        private static final String ROOT_PATTERN = "/**";
    
        private final SecurityProperties securityProperties;
    
        private TokenStore tokenStore;
    
        public ResourceServerConfiguration(final SecurityProperties securityProperties) {
            this.securityProperties = securityProperties;
        }
    
        @Override
        public void configure(final ResourceServerSecurityConfigurer resources) {
            resources.tokenStore(tokenStore());
        }
    
        @Override
        public void configure(HttpSecurity http) throws Exception {
            http.authorizeRequests()
            		// 排除路径验证
            		.antMatchers("/hello")
            			.permitAll()
                    .antMatchers(HttpMethod.GET, ROOT_PATTERN).access("#oauth2.hasScope('read')")
                    .antMatchers(HttpMethod.POST, ROOT_PATTERN).access("#oauth2.hasScope('write')")
                    .antMatchers(HttpMethod.PATCH, ROOT_PATTERN).access("#oauth2.hasScope('write')")
                    .antMatchers(HttpMethod.PUT, ROOT_PATTERN).access("#oauth2.hasScope('write')")
                    .antMatchers(HttpMethod.DELETE, ROOT_PATTERN).access("#oauth2.hasScope('write')");
        }
    
        @Bean
        public DefaultTokenServices tokenServices(final TokenStore tokenStore) {
            DefaultTokenServices tokenServices = new DefaultTokenServices();
            tokenServices.setTokenStore(tokenStore);
            return tokenServices;
        }
    
        @Bean
        public TokenStore tokenStore() {
            if (tokenStore == null) {
                tokenStore = new JwtTokenStore(jwtAccessTokenConverter());
            }
            return tokenStore;
        }
    
        @Bean
        public JwtAccessTokenConverter jwtAccessTokenConverter() {
            JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
            converter.setVerifierKey(getPublicKeyAsString());
            return converter;
        }
    
        private String getPublicKeyAsString() {
            try {
                return IOUtils.toString(securityProperties.getJwt().getPublicKey().getInputStream(), UTF_8);
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
        }
    
    }
