SSO ：同一个帐号在同一个公司不同系统上登陆
使用SpringSecurity实现类似于SSO登陆系统是十分简单的 下面我就搭建一个DEMO
首先来看看目录的结构
其中sso-demo是父工程项目 sso-client 、sso-client2分别对应2个资源服务器，sso-server是认证服务器
引入的pom文件
sso-demo
4.0.0 study.security.sso sso-demo 1.0.0-SNAPSHOT sso-server sso-client sso-client2 pom io.spring.platform platform-bom Brussels-SR4 pom import org.springframework.cloud spring-cloud-dependencies Dalston.SR2 pom import org.apache.maven.plugins maven-compiler-plugin 2.3.2 1.8 1.8 UTF-8
sso-server
sso-demo study.security.sso 1.0.0-SNAPSHOT 4.0.0 sso-server org.springframework.boot spring-boot-starter-security org.springframework.boot spring-boot-starter-web org.springframework.security.oauth spring-security-oauth2 org.springframework.security spring-security-jwt
sso-client与sso-client2 pom 中的 是一样的
1.sso-server
现在开始搭建认证服务器
认证服务器的目录结构如下
/**
* 认证服务器配置
* Created by ZhuPengWei on 2018/1/11.
*/
@Configuration
@EnableAuthorizationServer
public class SsoAuthenticationServerConfig extends AuthorizationServerConfigurerAdapter {
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory()
.withClient("client1")
.secret("client1")
.authorizedGrantTypes("authorization_code", "refresh_token")
.scopes("all")
.and()
.withClient("client2")
.secret("client2")
.authorizedGrantTypes("authorization_code", "refresh_token")
.scopes("all");
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.tokenStore(jwtTokenStore()).accessTokenConverter(jwtAccessTokenConverter());
}
/**
* 认证服务器的安全配置
*
* @param security
* @throws Exception
*/
@Override
public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
// 要访问认证服务器tokenKey的时候需要经过身份认证
security.tokenKeyAccess("isAuthenticated()");
}
@Bean
public TokenStore jwtTokenStore() {
return new JwtTokenStore(jwtAccessTokenConverter());
}
@Bean
public JwtAccessTokenConverter jwtAccessTokenConverter() {
JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
// 保证JWT安全的唯一方式
jwtAccessTokenConverter.setSigningKey("ZPW");
return jwtAccessTokenConverter;
}
}
/**
* 自定义用户登陆逻辑配置
* Created by ZhuPengWei on 2018/1/13.
*/
@Configuration
public class SsoSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;
/**
* 加密解密逻辑
*/
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
// 改成表单登陆的方式 所有请求都需要认证
http.formLogin().and().authorizeRequests().anyRequest().authenticated();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
// 用自己的登陆逻辑以及加密器
auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}
}
/**
* 自定义用户登陆
* Created by ZhuPengWei on 2018/1/13.
*/
@Component
public class SsoUserDetailsService implements UserDetailsService {
@Autowired
private PasswordEncoder passwordEncoder;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
return new User(username,
passwordEncoder.encode("123456"),
AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_USER"));
}
}
其中SsoApprovalEndPoint与SsoSpelView目的是去掉登陆之后授权的效果
注解 @FrameworkEndpoint
与@RestController注解相类似
如果声明和@FrameworkEndpoint一模一样的@RequestMapping
Spring框架处理的时候会优先处理@RestController里面的
/**
* 自定义认证逻辑
* Created by ZhuPengWei on 2018/1/13.
*/
@RestController
@SessionAttributes("authorizationRequest")
public class SsoApprovalEndpoint {
@RequestMapping("/oauth/confirm_access")
public ModelAndView getAccessConfirmation(Map model, HttpServletRequest request) throws Exception {
String template = createTemplate(model, request);
if (request.getAttribute("_csrf") != null) {
model.put("_csrf", request.getAttribute("_csrf"));
}
return new ModelAndView(new SsoSpelView(template), model);
}
protected String createTemplate(Map model, HttpServletRequest request) {
String template = TEMPLATE;
if (model.containsKey("scopes") || request.getAttribute("scopes") != null) {
template = template.replace("%scopes%", createScopes(model, request)).replace("%denial%", "");
} else {
template = template.replace("%scopes%", "").replace("%denial%", DENIAL);
}
if (model.containsKey("_csrf") || request.getAttribute("_csrf") != null) {
template = template.replace("%csrf%", CSRF);
} else {
template = template.replace("%csrf%", "");
}
return template;
}
private CharSequence createScopes(Map model, HttpServletRequest request) {
StringBuilder builder = new StringBuilder("");
@SuppressWarnings("unchecked")
Map scopes = (Map) (model.containsKey("scopes") ? model.get("scopes") : request
.getAttribute("scopes"));
for (String scope : scopes.keySet()) {
String approved = "true".equals(scopes.get(scope)) ? " checked" : "";
String denied = !"true".equals(scopes.get(scope)) ? " checked" : "";
String value = SCOPE.replace("%scope%", scope).replace("%key%", scope).replace("%approved%", approved)
.replace("%denied%", denied);
builder.append(value);
}
builder.append("
");
return builder.toString();
}
private static String CSRF = "";
private static String DENIAL = "";
// 对源代码进行处理 隐藏授权页面，并且使他自动提交
private static String TEMPLATE = "";
private static String SCOPE = "%scope%: Approve Deny ";
}
SsoSpelView 与 原来SpelView 是一样的 只不过原来SpelView 不是public的类
application.properties
server.port=9999 server.context-path=/server
2.sso-client
相对于认证服务器 资源服务器demo的配置就十分简单了
/**
* Created by ZhuPengWei on 2018/1/11.
*/
@SpringBootApplication
@RestController
@EnableOAuth2Sso
public class SsoClient1Application {
@GetMapping("/user")
public Authentication user(Authentication user) {
return user;
}
public static void main(String[] args) {
SpringApplication.run(SsoClient1Application.class, args);
}
}
SSO Client1 SSO Demo Client1
访问client2
application.properties
security.oauth2.client.client-id=client1 security.oauth2.client.client-secret=client1 #需要认证时候跳转的地址 security.oauth2.client.user-authorization-uri=http://127.0.0.1:9999/server/oauth/authorize #请求令牌地址 security.oauth2.client.access-token-uri=http://127.0.0.1:9999/server/oauth/token #解析 security.oauth2.resource.jwt.key-uri=http://127.0.0.1:9999/server/oauth/token_key #sso server.port=8080 server.context-path=/client1
3.sso-client2
资源服务器1和资源服务器2的目录结构是一样的，改了相关的参数
/**
* Created by ZhuPengWei on 2018/1/11.
*/
@SpringBootApplication
@RestController
@EnableOAuth2Sso
public class SsoClient2Application {
@GetMapping("/user")
public Authentication user(Authentication user) {
return user;
}
public static void main(String[] args) {
SpringApplication.run(SsoClient2Application.class, args);
}
}
SSO Client2 SSO Demo Client2
访问client1
security.oauth2.client.client-id=client2 security.oauth2.client.client-secret=client2 #需要认证时候跳转的地址 security.oauth2.client.user-authorization-uri=http://127.0.0.1:9999/server/oauth/authorize #请求令牌地址 security.oauth2.client.access-token-uri=http://127.0.0.1:9999/server/oauth/token #解析 security.oauth2.resource.jwt.key-uri=http://127.0.0.1:9999/server/oauth/token_key #sso server.port=8060 server.context-path=/client2
好了 基于JWT实现SSO单点登录的DEMO以及搭建完成了 下面来看看页面的效果
在初次访问的时候
图1
登陆成功之后
图2
图3
注意
写SsoApprovalEndPoint与SsoSpelView目的是去掉登陆之后授权的效果如果不写这2个类
在初次访问的登陆成功之后是有一步授权的操作的
比如说图1操作成功之后
点击Authorize才会跳转到图2
