前言
准备
2.1. 单点登录
SSO服务端和SSO客户端直接是通过授权以后发放Token的形式来访问受保护的资源 相对于浏览器来说,业务系统是服务端,相对于SSO服务端来说,业务系统是客户端 浏览器和业务系统之间通过会话正常访问 不是每次浏览器请求都要去SSO服务端去验证,只要浏览器和它所访问的服务端的会话有效它就可以正常访问
2.2. OAuth2
利用OAuth2实现单点登录
3.1. Spring Security 、OAuth2、JWT、SSO
认证服务器配置
4.1. Maven依赖

4.2. application.yml
spring:
datasource:
url: jdbc:mysql://localhost:3306/permission
username: root
password: 123456
driver-class-name: com.mysql.jdbc.Driver
jpa:
show-sql: true
session:
store-type: redis
redis:
host: 127.0.0.1
password: 123456
port: 6379
server:
port: 8080
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.core.token.DefaultToken;
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.token.DefaultTokenServices;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;
import javax.sql.DataSource;
/**
* @author ChengJianSheng
* @date 2019-02-11
*/
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private DataSource dataSource;
@Override
public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
security.allowFormAuthenticationForClients();
security.tokenKeyAccess("isAuthenticated()");
}
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.jdbc(dataSource);
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.accessTokenConverter(jwtAccessTokenConverter());
endpoints.tokenStore(jwtTokenStore());
// endpoints.tokenServices(defaultTokenServices());
}
/*@Primary
@Bean
public DefaultTokenServices defaultTokenServices() {
DefaultTokenServices defaultTokenServices = new DefaultTokenServices();
defaultTokenServices.setTokenStore(jwtTokenStore());
defaultTokenServices.setSupportRefreshToken(true);
return defaultTokenServices;
}*/
@Bean
public JwtTokenStore jwtTokenStore() {
return new JwtTokenStore(jwtAccessTokenConverter());
}
@Bean
public JwtAccessTokenConverter jwtAccessTokenConverter() {
JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
jwtAccessTokenConverter.setSigningKey("cjs"); // Sets the JWT signing key
return jwtAccessTokenConverter;
}
}
别忘了**@EnableAuthorizationServer** Token存储采用的是JWT 客户端以及登录用户这些配置存储在数据库,为了减少数据库的查询次数,可以从数据库读出来以后再放到内存中
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";
}
}
<!DOCTYPE html>

4.6. 定义客户端
4.7. 加载用户
package com.cjs.sso.domain;
import lombok.Data;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.User;
import java.util.Collection;
/**
* 大部分时候直接用User即可不必扩展
* @author ChengJianSheng
* @date 2019-02-11
*/
@Data
public class MyUser extends User {
private Integer departmentId; // 举个例子,部门ID
private String mobile; // 举个例子,假设我们想增加一个字段,这里我们增加一个mobile表示手机号
public MyUser(String username, String password, Collection<? extends GrantedAuthority> authorities) {
super(username, password, authorities);
}
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);
}
}
package com.cjs.sso.service;
import com.alibaba.fastjson.JSON;
import com.cjs.sso.domain.MyUser;
import com.cjs.sso.entity.SysPermission;
import com.cjs.sso.entity.SysUser;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Service;
import org.springframework.util.CollectionUtils;
import java.util.ArrayList;
import java.util.List;
/**
* @author ChengJianSheng
* @date 2019-02-11
*/
@Slf4j
@Service
public class MyUserDetailsService implements UserDetailsService {
@Autowired
private PasswordEncoder passwordEncoder;
@Autowired
private UserService userService;
@Autowired
private PermissionService permissionService;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
SysUser sysUser = userService.getByUsername(username);
if (null == sysUser) {
log.warn("用户{}不存在", username);
throw new UsernameNotFoundException(username);
}
List<SysPermission> permissionList = permissionService.findByUserId(sysUser.getId());
List<SimpleGrantedAuthority> authorityList = new ArrayList<>();
if (!CollectionUtils.isEmpty(permissionList)) {
for (SysPermission sysPermission : permissionList) {
authorityList.add(new SimpleGrantedAuthority(sysPermission.getCode()));
}
}
MyUser myUser = new MyUser(sysUser.getUsername(), passwordEncoder.encode(sysUser.getPassword()), authorityList);
log.info("登录成功!用户: {}", JSON.toJSONString(myUser));
return myUser;
}
}
4.8. 验证
两个客户端
5.1. Maven依赖

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
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;
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.WebSecurityConfigurerAdapter;
/**
* @author ChengJianSheng
* @date 2019-03-03
*/
@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();
}
}
}
最重要的注解是@EnableOAuth2Sso 权限控制这里采用Spring Security方法级别的访问控制,结合Thymeleaf可以很容易做权限控制 顺便多提一句,如果是前后端分离的话,前端需求加载用户的权限,然后判断应该显示那些按钮那些菜单
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;
/**
* @author ChengJianSheng
* @date 2019-03-03
*/
@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
