Spring Cloud Security 为构建安全的SpringBoot应用提供了一系列解决方案,结合Oauth2可以实现单点登录功能,本文将对其单点登录用法进行详细介绍。
单点登录(Single Sign On)指的是当有多个系统需要登录时,用户只需登录一个系统,就可以访问其他需要登录的系统而无需登录。
这里我们创建一个oauth2-client服务作为需要登录的客户端服务,使用上一节中的oauth2-jwt-server服务作为认证服务,当我们在oauth2-jwt-server服务上登录以后,就可以直接访问oauth2-client需要登录的接口,来演示下单点登录功能。
在pom.xml中添加相关依赖:
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-oauth2</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-security</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>io.jsonwebtoken</groupId><artifactId>jjwt</artifactId><version>0.9.0</version></dependency>Copy to clipboardErrorCopied
在application.yml中进行配置:
server:
port: 9501
servlet:
session:
cookie:
name: OAUTH2-CLIENT-SESSIONID #防止Cookie冲突,冲突会导致登录验证不通过
oauth2-server-url: http://localhost:9401
spring:
application:
name: oauth2-client
security:
oauth2: #与oauth2-server对应的配置
client:
client-id: admin
client-secret: admin123456
user-authorization-uri: ${oauth2-server-url}/oauth/authorize
access-token-uri: ${oauth2-server-url}/oauth/token
resource:
jwt:
key-uri: ${oauth2-server-url}/oauth/token_keyCopy to clipboardErrorCopied
在启动类上添加@EnableOAuth2Sso注解来启用单点登录功能:
@EnableOAuth2Sso@SpringBootApplicationpublicclassOauth2ClientApplication{publicstaticvoidmain(String[]args){SpringApplication.run(Oauth2ClientApplication.class,args);}}Copy to clipboardErrorCopied
添加接口用于获取当前登录用户信息:
/**
* Created by macro on 2019/9/30.
*/@RestController@RequestMapping("/user")publicclassUserController{@GetMapping("/getCurrentUser")publicObjectgetCurrentUser(Authenticationauthentication){returnauthentication;}}Copy to clipboardErrorCopied
修改oauth2-jwt-server模块中的AuthorizationServerConfig类,将绑定的跳转路径为http://localhost:9501/login,并添加获取秘钥时的身份认证。
/**
* 认证服务器配置
* Created by macro on 2019/9/30.
*/@Configuration@EnableAuthorizationServerpublicclassAuthorizationServerConfigextendsAuthorizationServerConfigurerAdapter{//以上省略一堆代码...@Overridepublicvoidconfigure(ClientDetailsServiceConfigurerclients)throwsException{clients.inMemory().withClient("admin").secret(passwordEncoder.encode("admin123456")).accessTokenValiditySeconds(3600).refreshTokenValiditySeconds(864000)// .redirectUris("http://www.baidu.com").redirectUris("http://localhost:9501/login")//单点登录时配置.scopes("all").authorizedGrantTypes("authorization_code","password","refresh_token");}@Overridepublicvoidconfigure(AuthorizationServerSecurityConfigurersecurity){security.tokenKeyAccess("isAuthenticated()");// 获取密钥需要身份认证,使用单点登录时必须配置}}Copy to clipboardErrorCopied
启动oauth2-client服务和oauth2-jwt-server服务;
访问客户端需要授权的接口http://localhost:9501/user/getCurrentUser会跳转到授权服务的登录界面;
进行登录操作后跳转到授权页面;
授权后会跳转到原来需要权限的接口地址,展示登录用户信息;
如果需要跳过授权操作进行自动授权可以添加autoApprove(true)配置:
/**
* 认证服务器配置
* Created by macro on 2019/9/30.
*/@Configuration@EnableAuthorizationServerpublicclassAuthorizationServerConfigextendsAuthorizationServerConfigurerAdapter{//以上省略一堆代码...@Overridepublicvoidconfigure(ClientDetailsServiceConfigurerclients)throwsException{clients.inMemory().withClient("admin").secret(passwordEncoder.encode("admin123456")).accessTokenValiditySeconds(3600).refreshTokenValiditySeconds(864000)// .redirectUris("http://www.baidu.com").redirectUris("http://localhost:9501/login")//单点登录时配置.autoApprove(true)//自动授权配置.scopes("all").authorizedGrantTypes("authorization_code","password","refresh_token");}}Copy to clipboardErrorCopied
这里我们使用Postman来演示下如何使用正确的方式调用需要登录的客户端接口。
访问客户端需要登录的接口:http://localhost:9501/user/getCurrentUser
使用Oauth2认证方式获取访问令牌:
输入获取访问令牌的相关信息,点击请求令牌:
此时会跳转到认证服务器进行登录操作:
登录成功后使用获取到的令牌:
最后请求接口可以获取到如下信息:
{
"authorities": [
{
"authority": "admin"
}
],
"details": {
"remoteAddress": "0:0:0:0:0:0:0:1",
"sessionId": "63BB793E35383B2FFC608333B3BF4988",
"tokenValue": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX25hbWUiOiJtYWNybyIsInNjb3BlIjpbImFsbCJdLCJleHAiOjE1NzI2OTAxNzUsImF1dGhvcml0aWVzIjpbImFkbWluIl0sImp0aSI6IjIwN2U5MTQzLTVjNTUtNDhkMS1iZmU3LTgwMzUyZTQ3Y2QyZCIsImNsaWVudF9pZCI6ImFkbWluIiwiZW5oYW5jZSI6ImVuaGFuY2UgaW5mbyJ9.xf3cBu9yCm0sME0j3UcP53FwF4tJVJC5aJbEj_Y2XcU",
"tokenType": "bearer",

},
"authenticated": true,
"userAuthentication": {
"authorities": [
{
"authority": "admin"
}
],
"details": null,
"authenticated": true,
"principal": "macro",
"credentials": "N/A",
"name": "macro"
},
"clientOnly": false,
"oauth2Request": {
"clientId": "admin",
"scope": [
"all"
],
"requestParameters": {
"client_id": "admin"
},
"resourceIds": [],
"authorities": [],
"approved": true,
"refresh": false,
"redirectUri": null,
"responseTypes": [],
"extensions": {},
"grantType": null,
"refreshTokenRequest": null
},
"principal": "macro",
"credentials": "",
"name": "macro"

添加配置开启基于方法的权限校验:
/**
* 在接口上配置权限时使用
* Created by macro on 2019/10/11.
*/@Configuration@EnableGlobalMethodSecurity(prePostEnabled=true)@Order(101)publicclassSecurityConfigextendsWebSecurityConfigurerAdapter{}Copy to clipboardErrorCopied
在UserController中添加需要admin权限的接口:
/**
* Created by macro on 2019/9/30.
*/@RestController@RequestMapping("/user")publicclassUserController{@PreAuthorize("hasAuthority('admin')")@GetMapping("/auth/admin")publicObjectadminAuth(){return"Has admin auth!";}}Copy to clipboardErrorCopied
访问需要admin权限的接口:http://localhost:9501/user/auth/admin
使用没有admin权限的帐号,比如andy:123456获取令牌后访问该接口,会发现没有权限访问。
