本指南逐步介紹了使用Spring Boot 2創建集中式身份驗證和授權服務器的過程，還將提供演示資源服務器。

如果您不熟悉OAuth2，建議您閱讀此書。

先決條件

• JDK 1.8
• 文本編輯器或您喜歡的IDE
• Maven 3.0+

實施概述

對于這個項目，我們將通過Spring Boot使用Spring Security 5 。 如果您熟悉早期版本，那么《 Spring Boot遷移指南》可能會有用。

OAuth2術語

• 資源所有者
  • 授權應用程序訪問其帳戶的用戶。
• 資源服務器 ：
  • 在client獲取access token之后處理已認證請求的服務器。
• 客戶
  • 代表資源所有者訪問受保護資源的應用程序。
• 授權服務器
  • 在成功驗證client和resource owner并授權請求之后，發出訪問令牌的服務器。
• 訪問令牌
  • 用于訪問受保護資源的唯一令牌
• 范圍
  • 許可
• 贈款類型
  • grant是一種獲取訪問令牌的方法。

授權服務器

為了構建我們的Authorization Server我們將通過Spring Boot 2.0.x使用Spring Security5.x 。

依存關系

您可以轉到start.spring.io并生成一個新項目，然后添加以下依賴項：

<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId></dependency><dependency><groupId>org.springframework.security.oauth.boot</groupId><artifactId>spring-security-oauth2-autoconfigure</artifactId><version>2.1.2.RELEASE</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jdbc</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId><optional>true</optional></dependency><dependency><groupId>com.h2database</groupId><artifactId>h2</artifactId><scope>runtime</scope></dependency> </dependencies>

數據庫

出于本指南的考慮，我們將使用H2數據庫 。
在這里，您可以找到Spring Security所需的參考OAuth2 SQL模式。

CREATE TABLE IF NOT EXISTS oauth_client_details (client_id VARCHAR(256) PRIMARY KEY,resource_ids VARCHAR(256),client_secret VARCHAR(256) NOT NULL,scope VARCHAR(256),authorized_grant_types VARCHAR(256),web_server_redirect_uri VARCHAR(256),authorities VARCHAR(256),access_token_validity INTEGER,refresh_token_validity INTEGER,additional_information VARCHAR(4000),autoapprove VARCHAR(256) );CREATE TABLE IF NOT EXISTS oauth_client_token (token_id VARCHAR(256),token BLOB,authentication_id VARCHAR(256) PRIMARY KEY,user_name VARCHAR(256),client_id VARCHAR(256) );CREATE TABLE IF NOT EXISTS oauth_access_token (token_id VARCHAR(256),token BLOB,authentication_id VARCHAR(256),user_name VARCHAR(256),client_id VARCHAR(256),authentication BLOB,refresh_token VARCHAR(256) );CREATE TABLE IF NOT EXISTS oauth_refresh_token (token_id VARCHAR(256),token BLOB,authentication BLOB );CREATE TABLE IF NOT EXISTS oauth_code (code VARCHAR(256), authentication BLOB );

然后添加以下條目

-- The encrypted client_secret it `secret` INSERT INTO oauth_client_details (client_id, client_secret, scope, authorized_grant_types, authorities, access_token_validity)VALUES ('clientId', '{bcrypt}$2a$10$vCXMWCn7fDZWOcLnIEhmK.74dvK1Eh8ae2WrWlhr2ETPLoxQctN4.', 'read,write', 'password,refresh_token,client_credentials', 'ROLE_CLIENT', 300);

上面的client_secret是使用bcrypt生成的。
前綴{bcrypt}是必需的，因為我們將使用Spring Security 5.x的DelegatingPasswordEncoder的新功能。

在下面的頁面中，您可以找到Spring的org.springframework.security.core.userdetails.jdbc.JdbcDaoImpl使用的User和Authority參考SQL模式。

CREATE TABLE IF NOT EXISTS users (id INT AUTO_INCREMENT PRIMARY KEY,username VARCHAR(256) NOT NULL,password VARCHAR(256) NOT NULL,enabled TINYINT(1),UNIQUE KEY unique_username(username) );CREATE TABLE IF NOT EXISTS authorities (username VARCHAR(256) NOT NULL,authority VARCHAR(256) NOT NULL,PRIMARY KEY(username, authority) );

與之前相同，為用戶及其權限添加以下條目。

-- The encrypted password is `pass` INSERT INTO users (id, username, password, enabled) VALUES (1, 'user', '{bcrypt}$2a$10$cyf5NfobcruKQ8XGjUJkEegr9ZWFqaea6vjpXWEaSqTa2xL9wjgQC', 1); INSERT INTO authorities (username, authority) VALUES ('user', 'ROLE_USER');

Spring安全配置

添加以下Spring配置類。

import org.springframework.context.annotation.Bean; import org.springframework.security.authentication.AuthenticationManager; import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.core.userdetails.UserDetailsService; import org.springframework.security.core.userdetails.jdbc.JdbcDaoImpl; import org.springframework.security.crypto.factory.PasswordEncoderFactories; import org.springframework.security.crypto.password.PasswordEncoder;import javax.sql.DataSource;@EnableWebSecurity public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {private final DataSource dataSource;private PasswordEncoder passwordEncoder;private UserDetailsService userDetailsService;public WebSecurityConfiguration(final DataSource dataSource) {this.dataSource = dataSource;}@Overrideprotected void configure(final AuthenticationManagerBuilder auth) throws Exception {auth.userDetailsService(userDetailsService()).passwordEncoder(passwordEncoder());}@Bean@Overridepublic AuthenticationManager authenticationManagerBean() throws Exception {return super.authenticationManagerBean();}@Beanpublic PasswordEncoder passwordEncoder() {if (passwordEncoder == null) {passwordEncoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();}return passwordEncoder;}@Beanpublic UserDetailsService userDetailsService() {if (userDetailsService == null) {userDetailsService = new JdbcDaoImpl();((JdbcDaoImpl) userDetailsService).setDataSource(dataSource);}return userDetailsService;}}

引用Spring Blog ：

@EnableWebSecurity批注和WebSecurityConfigurerAdapter一起提供基于Web的安全性。

如果您使用的是Spring Boot，則將自動配置DataSource對象，您可以將其注入到類中，而不必自己定義。 需要將其注入到UserDetailsService中，該服務將使用Spring Security提供的JdbcDaoImpl ，如有必要，您可以將其替換為自己的實現。

由于某些自動配置的Spring @Bean需要Spring Security的AuthenticationManager因此有必要重寫authenticationManagerBean方法，并以@Bean authenticationManagerBean注釋。

PasswordEncoder將由PasswordEncoderFactories.createDelegatingPasswordEncoder()處理，其中基于前綴處理一些密碼編碼器和委托，在我們的示例中，我們使用{bcrypt}作為密碼的前綴。

授權服務器配置

授權服務器驗證client和user憑證并提供令牌。

添加以下Spring配置類。

import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.security.authentication.AuthenticationManager; 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.JdbcTokenStore;import javax.sql.DataSource;@Configuration @EnableAuthorizationServer public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {private final DataSource dataSource;private final PasswordEncoder passwordEncoder;private final AuthenticationManager authenticationManager;private TokenStore tokenStore;public AuthorizationServerConfiguration(final DataSource dataSource, final PasswordEncoder passwordEncoder,final AuthenticationManager authenticationManager) {this.dataSource = dataSource;this.passwordEncoder = passwordEncoder;this.authenticationManager = authenticationManager;}@Beanpublic TokenStore tokenStore() {if (tokenStore == null) {tokenStore = new JdbcTokenStore(dataSource);}return tokenStore;}@Beanpublic DefaultTokenServices tokenServices(final ClientDetailsService clientDetailsService) {DefaultTokenServices tokenServices = new DefaultTokenServices();tokenServices.setSupportRefreshToken(true);tokenServices.setTokenStore(tokenStore());tokenServices.setClientDetailsService(clientDetailsService);tokenServices.setAuthenticationManager(authenticationManager);return tokenServices;}@Overridepublic void configure(final ClientDetailsServiceConfigurer clients) throws Exception {clients.jdbc(dataSource);}@Overridepublic void configure(final AuthorizationServerEndpointsConfigurer endpoints) {endpoints.authenticationManager(authenticationManager).tokenStore(tokenStore());}@Overridepublic void configure(final AuthorizationServerSecurityConfigurer oauthServer) {oauthServer.passwordEncoder(passwordEncoder).tokenKeyAccess("permitAll()").checkTokenAccess("isAuthenticated()");}}

用戶信息端點

現在，我們需要定義一個端點，在該端點上可以將授權令牌解碼為Authorization對象，以添加以下類。

import org.springframework.http.ResponseEntity; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;import java.security.Principal;@RestController @RequestMapping("/profile") public class UserController {@GetMapping("/me")public ResponseEntityget(final Principal principal) {return ResponseEntity.ok(principal);}}

資源服務器配置

資源服務器托管HTTP資源 ，其中的HTTP資源可以是文檔，照片或其他內容，在我們的情況下，它將是受OAuth2保護的REST API。

依存關系

<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId></dependency><dependency><groupId>org.springframework.security.oauth.boot</groupId><artifactId>spring-security-oauth2-autoconfigure</artifactId><version>2.1.2.RELEASE</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId><optional>true</optional></dependency> </dependencies>

定義我們受保護的API

下面的代碼定義了端點/me并返回Principal對象，它要求經過身份驗證的用戶具有ROLE_USER的訪問權限。

import org.springframework.http.ResponseEntity; import org.springframework.security.access.prepost.PreAuthorize; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;import java.security.Principal;@RestController @RequestMapping("/me") public class UserController {@GetMapping@PreAuthorize("hasRole('ROLE_USER')")public ResponseEntity<Principal> get(final Principal principal) {return ResponseEntity.ok(principal);}}

@PreAuthorize批注會在執行代碼之前驗證用戶是否具有給定角色，以使其正常工作，有必要啟用prePost批注，為此添加以下類：

import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;@EnableGlobalMethodSecurity(prePostEnabled = true) public class WebSecurityConfiguration {}

這里的重要部分是@EnableGlobalMethodSecurity(prePostEnabled = true)批注， prePostEnabled標志默認情況下設置為false ，將其設置為true可使@PreAuthorize批注起作用。

資源服務器配置

現在，讓我們為資源服務器添加Spring的配置。

import org.springframework.context.annotation.Configuration; import org.springframework.http.HttpMethod; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer; import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;@Configuration @EnableResourceServer public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {}

來自Javadoc的@EnableResourceServer批注：

OAuth2資源服務器的便捷注釋，可啟用Spring Security過濾器，該過濾器通過傳入的OAuth2令牌對請求進行身份驗證。 用戶應添加此批注并提供類型為{@link ResourceServerConfigurer}的@Bean （例如，通過{@link ResourceServerConfigurerAdapter}），用于指定資源的詳細信息（URL路徑和資源ID）。 為了使用此過濾器，您必須在應用程序中的某個位置{@link EnableWebSecurity}，使用該注釋的位置相同，也可以使用其他位置。

現在我們已經準備好所有必需的代碼，我們需要配置RemoteTokenServices ，對我們來說幸運的是，Spring提供了一個配置屬性，可以在其中設置可以將令牌轉換為Authentication對象的url。

security:oauth2:resource:user-info-uri: http://localhost:9001/profile/me

一起測試

為了一起測試，我們需要同時旋轉Authorization Server和Resource Server ，在我的設置中，它將相應地在端口9001和9101上運行。

生成令牌

$ curl -u clientId:secret -X POST localhost:9001/oauth/token\?grant_type=password\&username=user\&password=pass{"access_token" : "e47876b0-9962-41f1-ace3-e3381250ccea","token_type" : "bearer","refresh_token" : "8e17a71c-cb39-4904-8205-4d9f8c71aeef","expires_in" : 299,"scope" : "read write" }

訪問資源

既然已經生成了令牌，請復制access_token并將其添加到Authorization HTTP Header上的請求中，例如：

$ curl -i localhost:9101/me -H "Authorization: Bearer c06a4137-fa07-4d9a-97f9-85d1ba820d3a"{"authorities" : [ {"authority" : "ROLE_USER"} ],"details" : {"remoteAddress" : "127.0.0.1","sessionId" : null,"tokenValue" : "c06a4137-fa07-4d9a-97f9-85d1ba820d3a","tokenType" : "Bearer","decodedDetails" : null},"authenticated" : true,"userAuthentication" : {"authorities" : [ {"authority" : "ROLE_USER"} ],"details" : {"authorities" : [ {"authority" : "ROLE_USER"} ],"details" : {"remoteAddress" : "127.0.0.1","sessionId" : null,"tokenValue" : "c06a4137-fa07-4d9a-97f9-85d1ba820d3a","tokenType" : "Bearer","decodedDetails" : null},"authenticated" : true,"userAuthentication" : {"authorities" : [ {"authority" : "ROLE_USER"} ],"details" : {"grant_type" : "password","username" : "user"},"authenticated" : true,"principal" : {"password" : null,"username" : "user","authorities" : [ {"authority" : "ROLE_USER"} ],"accountNonExpired" : true,"accountNonLocked" : true,"credentialsNonExpired" : true,"enabled" : true},"credentials" : null,"name" : "user"},"clientOnly" : false,"oauth2Request" : {"clientId" : "clientId","scope" : [ "read", "write" ],"requestParameters" : {"grant_type" : "password","username" : "user"},"resourceIds" : [ ],"authorities" : [ {"authority" : "ROLE_CLIENT"} ],"approved" : true,"refresh" : false,"redirectUri" : null,"responseTypes" : [ ],"extensions" : { },"grantType" : "password","refreshTokenRequest" : null},"credentials" : "","principal" : {"password" : null,"username" : "user","authorities" : [ {"authority" : "ROLE_USER"} ],"accountNonExpired" : true,"accountNonLocked" : true,"credentialsNonExpired" : true,"enabled" : true},"name" : "user"},"authenticated" : true,"principal" : "user","credentials" : "N/A","name" : "user"},"principal" : "user","credentials" : "","clientOnly" : false,"oauth2Request" : {"clientId" : null,"scope" : [ ],"requestParameters" : { },"resourceIds" : [ ],"authorities" : [ ],"approved" : true,"refresh" : false,"redirectUri" : null,"responseTypes" : [ ],"extensions" : { },"grantType" : null,"refreshTokenRequest" : null},"name" : "user" }
