通常公司肯定不止一个系统,每个系统都需要进行认证和权限控制,不可能每个每个系统都自己去写,这个时候需要把登录单独提出来
- 登录和授权是统一的
- 业务系统该怎么写还怎么写
最近学习了一下Spring Security,今天用Spring Security OAuth2简单写一个单点登录的示例
在此之前,需要对OAuth2有一点了解
这里有几篇文章可能会对你有帮助
1. 服务器端配置
1.1. Maven依赖

1.2. 配置授权服务器
package com.cjs.example.config; import org.springframework.context.annotation.Configuration;
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 javax.annotation.Resource;
import javax.sql.DataSource; @Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter { @Resource
private DataSource dataSource; /**
* 配置授权服务器的安全,意味着实际上是/oauth/token端点。
* /oauth/authorize端点也应该是安全的
* 默认的设置覆盖到了绝大多数需求,所以一般情况下你不需要做任何事情。
*/
@Override
public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
super.configure(security);
} /**
* 配置ClientDetailsService
* 注意,除非你在下面的configure(AuthorizationServerEndpointsConfigurer)中指定了一个AuthenticationManager,否则密码授权方式不可用。
* 至少配置一个client,否则服务器将不会启动。
*/
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.jdbc(dataSource);
} /**
* 该方法是用来配置Authorization Server endpoints的一些非安全特性的,比如token存储、token自定义、授权类型等等的
* 默认情况下,你不需要做任何事情,除非你需要密码授权,那么在这种情况下你需要提供一个AuthenticationManager
*/
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
super.configure(endpoints);
}
}
说明:这里授权服务器我主要是配置了注册客户端,客户端可以从内存中或者数据库中加载,这里我从数据库中加载,因为这样感觉更真实一点儿。
查看JdbcClientDetailsService源码我们不难看出其表结构。(PS:也可以自定义,就像UserDetailsService那样)
这里,我准备的SQL脚本如下:
CREATE TABLE oauth_client_details (
client_id VARCHAR(256) PRIMARY KEY,
resource_ids VARCHAR(256),
client_secret VARCHAR(256),
scope VARCHAR(256),
authorized_grant_types VARCHAR(256),
web_server_redirect_uri VARCHAR(256),
authorities VARCHAR(256),
access_token_validity INTEGER,
refresh_token_validity INTEGER,
additional_information VARCHAR(4096),
autoapprove VARCHAR(256)
);
INSERT INTO oauth_client_details (client_id, client_secret, scope, authorized_grant_types, web_server_redirect_uri, autoapprove)
VALUES ('MemberSystem', '$2a$10$dYRcFip80f0jIKGzRGulFelK12036xWQKgajanfxT65QB4htsEXNK', 'user_info', 'authorization_code', 'http://localhost:8081/login', 'user_info');
INSERT INTO oauth_client_details (client_id, client_secret, scope, authorized_grant_types, web_server_redirect_uri, autoapprove)
VALUES ('CouponSystem', '$2a$10$dYRcFip80f0jIKGzRGulFelK12036xWQKgajanfxT65QB4htsEXNK', 'user_info', 'authorization_code', 'http://localhost:8082/login', 'user_info');
这里注册了两个客户端,分别是MemberSystem和CouponSystem。
1.3. 配置WebSecurity
package com.cjs.example.config; import com.cjs.example.support.MyUserDetailsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
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; @Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired
private MyUserDetailsService myUserDetailsService; @Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/oauth/**","/login/**", "/logout").permitAll()
.anyRequest().authenticated() // 其他地址的访问均需验证权限
.and()
.formLogin()
.loginPage("/login")
.and()
.logout().logoutSuccessUrl("/");
} @Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/assets/**");
} @Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(myUserDetailsService).passwordEncoder(passwordEncoder());
} @Bean
@Override
public AuthenticationManager authenticationManager() throws Exception {
return super.authenticationManager();
} @Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
} }
说明:
- 这里,主要配置了UserDetailsService
package com.cjs.example.support; import com.cjs.example.domain.SysPermission;
import com.cjs.example.domain.SysRole;
import com.cjs.example.domain.SysUser;
import com.cjs.example.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service; import java.util.ArrayList;
import java.util.List; @Service
public class MyUserDetailsService implements UserDetailsService { @Autowired
private UserService userService; /**
* 授权的时候是对角色授权,而认证的时候应该基于资源,而不是角色,因为资源是不变的,而用户的角色是会变的
*/ @Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
SysUser sysUser = userService.getUserByName(username);
if (null == sysUser) {
throw new UsernameNotFoundException(username);
}
List<SimpleGrantedAuthority> authorities = new ArrayList<>();
for (SysRole role : sysUser.getRoleList()) {
for (SysPermission permission : role.getPermissionList()) {
authorities.add(new SimpleGrantedAuthority(permission.getCode()));
}
} return new User(sysUser.getUsername(), sysUser.getPassword(), authorities);
}
}
1.4. 新建登录页面
package com.cjs.example.controller; import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping; @Controller
public class LoginController { @RequestMapping("/login")
public String login() {
return "login";
} @GetMapping("/index")
public String index() {
return "index";
} }
1.5. application.yml
server:
port:
spring:
datasource:
url: jdbc:mysql://10.123.52.189:3306/oh_coupon
username: devdb
password: d^V$0Fu!/-<s
driver-class-name: com.mysql.jdbc.Driver
logging:
level:
root: debug
2. 客户端配置
2.1. Maven依赖
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<java.version>1.8</java.version>
</properties> <dependencies>
<dependency>

</dependencies> <build>
<plugins>
<plugin>

<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build> </project>
2.2. WebSecurity配置
package com.cjs.example.config; import org.springframework.boot.autoconfigure.security.oauth2.client.EnableOAuth2Sso;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; @EnableOAuth2Sso
@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class UiSecurityConfig extends WebSecurityConfigurerAdapter { @Override
public void configure(HttpSecurity http) throws Exception {
http.antMatcher("/**")
.authorizeRequests()
.antMatchers("/", "/login**").permitAll()
.anyRequest()
.authenticated();
} }
说明:
这里最重要的是应用了@EnableOAuth2Sso注解
Spring Boot 1.x 版本和 2.x 版本在OAuth2这一块的差异还是比较大的,在Spring Boot 2.x 中没有@EnableOAuth2Sso这个注解,所以我引用了spring-security-oauth2-autoconfigure
2.3. 定义一个简单的控制器
package com.cjs.example.controller; import com.cjs.example.domain.Member;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView; import java.util.ArrayList;
import java.util.List; @Controller
@RequestMapping("/member")
public class MemberController { /**
* 会员列表页面
*/
@RequestMapping("/list")
public ModelAndView list() {
ModelAndView modelAndView = new ModelAndView("member/list");
return modelAndView;
} /**
* 导出
*/
@PreAuthorize("hasAuthority('memberExport')")
@ResponseBody
@RequestMapping("/export")
public List<Member> export() {
Member member = new Member();
member.setName("苏九儿");
member.setCode("1000");
member.setMobile("13112345678");
member.setGender(1);
Member member1 = new Member();
member1.setName("郭双");
member1.setCode("1001");
member1.setMobile("15812346723");
member1.setGender(1);
List<Member> list = new ArrayList<>();
list.add(member);
list.add(member1);
return list;
} /**
* 详情
*/
@PreAuthorize("hasAuthority('memberDetail')")
@RequestMapping("/detail")
public ModelAndView detail() {
return new ModelAndView(" member/detail");
}
}
2.4. application.yml
server:
port:
servlet:
session:
cookie:
name: UISESSIONMEMBER security:
oauth2:
client:
client-id: MemberSystem
client-secret:
access-token-uri: http://localhost:8080/oauth/token
user-authorization-uri: http://localhost:8080/oauth/authorize
resource:
user-info-uri: http://localhost:8080/user/me
logging:
level:
root: debug
spring:
thymeleaf:
cache: false
说明:
- 这里需要注意的是不要忘记设置cookie-name,不然会有一些莫名其妙的问题,比如“User must be authenticated with Spring Security before authorization can be completed”
3. 运行效果
在这个例子中,会员系统(localhost:8081)和营销系统(localhost:8082)是两个系统
可以看到,当我们登录会员系统以后,再进营销系统就不需要登录了。
3.1. 遗留问题
- 退出
- 记住我
