SSO ：同一个帐号在同一个公司不同系统上登陆
这里写图片描述
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
这里写图片描述
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

</project>

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

这里写图片描述

/**
 * 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

这里写图片描述

/**
 * 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<String, Object> 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<String, Object> 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<String, Object> model, HttpServletRequest request) {
        StringBuilder builder = new StringBuilder("<ul>");
        @SuppressWarnings("unchecked")
        Map<String, String> scopes = (Map<String, String>) (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("</ul>");
        return builder.toString();
    }

    private static String CSRF = "<input type='hidden' name='${_csrf.parameterName}' value='${_csrf.token}' />";

    private static String DENIAL = "<form id='denialForm' name='denialForm' action='${path}/oauth/authorize' method='post'><input name='user_oauth_approval' value='false' type='hidden'/>%csrf%<label><input name='deny' value='Deny' type='submit'/></label></form>";

    // 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 = "<html><body><div style='display:none;'> <h1>OAuth Approval</h1>"
            + "<p>Do you authorize '${authorizationRequest.clientId}' to access your protected resources?</p>"
            + "<form id='confirmationForm' name='confirmationForm' action='${path}/oauth/authorize' method='post'><input name='user_oauth_approval' value='true' type='hidden'/>%csrf%%scopes%<label><input name='authorize' value='Authorize' type='submit'/></label></form>"
            + "%denial%</div><script>document.getElementById('confirmationForm').submit();</script></body></html>";

    private static String SCOPE = "<li><div class='form-group'>%scope%: <input type='radio' name='%key%'"
            + " value='true'%approved%>Approve</input> <input type='radio' name='%key%' value='false'%denied%>Deny</input></div></li>";

}

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

这里写图片描述

/**
 * 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);
    }
}

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>SSO Client1</title>
</head>
<body>
<h1>SSO Demo Client1</h1>
<a href="http://127.0.0.1:8060/client2/index.html">访问client2</a>

</body>
</html>

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);
    }
}
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>SSO Client2</title>
</head>
<body>
<h1>SSO Demo Client2</h1>
<a href="http://127.0.0.1:8080/client1/index.html">访问client1</a>

</body>
</html>
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

这里写图片描述

登陆成功之后
图2
这里写图片描述

图3
这里写图片描述

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

这里写图片描述
点击Authorize才会跳转到图2
