2.2. OAuth2
推荐以下几篇博客
《OAuth 2.0》
《Spring Security对OAuth2的支持》
3.利用OAuth2实现单点登录
接下来，只讲跟本例相关的一些配置，不讲原理，不讲为什么
众所周知，在OAuth2在有授权服务器、资源服务器、客户端这样几个角色，当我们用它来实现SSO的时候是不需要资源服务器这个角色的，有授权服务器和客户端就够了。
授权服务器当然是用来做认证的，客户端就是各个应用系统，我们只需要登录成功后拿到用户信息以及用户所拥有的权限即可
之前我一直认为把那些需要权限控制的资源放到资源服务器里保护起来就可以实现权限控制，其实是我想错了，权限控制还得通过Spring Security或者自定义拦截器来做
3.1. Spring Security 、OAuth2、JWT、SSO
在本例中，一定要分清楚这几个的作用
首先，SSO是一种思想，或者说是一种解决方案，是抽象的，我们要做的就是按照它的这种思想去实现它
其次，OAuth2是用来允许用户授权第三方应用访问他在另一个服务器上的资源的一种协议，它不是用来做单点登录的，但我们可以利用它来实现单点登录。在本例实现SSO的过程中，受保护的资源就是用户的信息（包括，用户的基本信息，以及用户所具有的权限），而我们想要访问这这一资源就需要用户登录并授权，OAuth2服务端负责令牌的发放等操作，这令牌的生成我们采用JWT，也就是说JWT是用来承载用户的Access_Token的
最后，Spring Security是用于安全访问的，这里我们我们用来做访问权限控制
4.认证服务器配置

4.2. application.yml
spring:
datasource:

driver-class-name: com.mysql.jdbc.Driver

redis:

4.3. AuthorizationServerConfig（重要）
package com.cjs.sso.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;
import javax.sql.DataSource;
/**

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private DataSource dataSource;
@Override
public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
security.allowFormAuthenticationForClients();
security.tokenKeyAccess("isAuthenticated()");
}

return new JwtTokenStore(jwtAccessTokenConverter());
}
@Bean
public JwtAccessTokenConverter jwtAccessTokenConverter() {
JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
jwtAccessTokenConverter.setSigningKey("cjs"); // Sets the JWT signing key
return jwtAccessTokenConverter;
}
}
说明：
4.4. WebSecurityConfig（重要）
package com.cjs.sso.config;
import com.cjs.sso.service.MyUserDetailsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
/**
* @author ChengJianSheng
* @date 2019-02-11
*/
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private MyUserDetailsService userDetailsService;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}
@Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/assets/**", "/css/**", "/images/**");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.formLogin()
.loginPage("/login")
.and()
.authorizeRequests()
.antMatchers("/login").permitAll()
.anyRequest()
.authenticated()
.and().csrf().disable().cors();
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
4.5. 自定义登录页面（一般来讲都是要自定义的）
package com.cjs.sso.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
/**
* @author ChengJianSheng
* @date 2019-02-12
*/
@Controller
public class LoginController {
@GetMapping("/login")
public String login() {
return "login";
}
@GetMapping("/")
public String index() {
return "index";
}
}
自定义登录页面的时候，只需要准备一个登录页面，然后写个Controller令其可以访问到即可，登录页面表单提交的时候method一定要是post，最重要的时候action要跟访问登录页面的url一样
千万记住了，访问登录页面的时候是GET请求，表单提交的时候是POST请求，其它的就不用管了

4.6. 定义客户端

}
public MyUser(String username, String password, boolean enabled, boolean accountNonExpired, boolean credentialsNonExpired, boolean accountNonLocked, Collection<? extends GrantedAuthority> authorities) {
super(username, password, enabled, accountNonExpired, credentialsNonExpired, accountNonLocked, authorities);

4.8. 验证
当我们看到这个界面的时候，表示认证服务器配置完成

5.2. application.yml
server:
port: 8082
servlet:
context-path: /memberSystem
security:
oauth2:
client:
client-id: UserManagement
client-secret: user123
access-token-uri: http://localhost:8080/oauth/token
user-authorization-uri: http://localhost:8080/oauth/authorize
resource:
jwt:
key-uri: http://localhost:8080/oauth/token_key
这里context-path不要设成/，不然重定向获取code的时候回被拦截
5.3. WebSecurityConfig
package com.cjs.example.config;
import com.cjs.example.util.EnvironmentUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.security.oauth2.client.EnableOAuth2Sso;
import org.springframework.context.annotation.Configuration;

@EnableOAuth2Sso
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private EnvironmentUtils environmentUtils;
@Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/bootstrap/**");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
if ("local".equals(environmentUtils.getActiveProfile())) {
http.authorizeRequests().anyRequest().permitAll();
}else {
http.logout().logoutSuccessUrl("http://localhost:8080/logout")
.and()
.authorizeRequests()
.anyRequest().authenticated()
.and()
.csrf().disable();
}
}
}
说明：
5.4. MemberController
package com.cjs.example.controller;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.security.core.Authentication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import java.security.Principal;
/**

*/
@Controller
@RequestMapping("/member")
public class MemberController {
@GetMapping("/list")
public String list() {
return "member/list";
}
@GetMapping("/info")
@ResponseBody
public Principal info(Principal principal) {
return principal;
}
@GetMapping("/me")
@ResponseBody
public Authentication me(Authentication authentication) {
return authentication;
}
@PreAuthorize("hasAuthority('member:save')")
@ResponseBody
@PostMapping("/add")
public String add() {
return "add";
}
@PreAuthorize("hasAuthority('member:detail')")
@ResponseBody
@GetMapping("/detail")
public String detail() {
return "detail";
}
}
5.5. Order项目跟它是一样的
server:
port: 8083
servlet:
context-path: /orderSystem
security:
oauth2:
client:
client-id: OrderManagement
client-secret: order123
access-token-uri: http://localhost:8080/oauth/token
user-authorization-uri: http://localhost:8080/oauth/authorize
resource:
jwt:
key-uri: http://localhost:8080/oauth/token_key
5.6. 关于退出
退出就是清空用于与SSO客户端建立的所有的会话，简单的来说就是使所有端点的Session失效，如果想做得更好的话可以令Token失效，但是由于我们用的JWT，故而撤销Token就不是那么容易，关于这一点，在官网上也有提到：
本例中采用的方式是在退出的时候先退出业务服务器，成功以后再回调认证服务器，但是这样有一个问题，就是需要主动依次调用各个业务服务器的logout
