Spring Security OAuth2 SSO

2018-07-12 07:34:29来源：博客园 阅读 ()

新老客户大回馈,云服务器低至5折

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

  1. 登录和授权是统一的
  2. 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

</project>

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：

  1. 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: 8080
spring:
  datasource:
    url: jdbc:mysql://10.123.52.189:3306/oh_coupon
    username: devdb
    password: d^V$0Fu!/6-<s
    driver-class-name: com.mysql.jdbc.Driver
logging:
  level:
    root: debug

2. 客户端配置

2.1. Maven依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>

        <dependency>
            <groupId>org.springframework.security.oauth.boot</groupId>
            <artifactId>spring-security-oauth2-autoconfigure</artifactId>
            <version>2.0.1.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <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: 8081
  servlet:
    session:
      cookie:
        name: UISESSIONMEMBER

security:
  oauth2:
    client:
      client-id: MemberSystem
      client-secret: 12345
      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：

  1. 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

  1. 退出
  2. 记住我
