六一儿童节全网最全的微服务+Outh2套餐，你确定不来试一试？（入门到精通，附源码）满足你的味蕾需要（二）

2023-11-15

咱们废话不多说，直接开干！！！

一、项目目录

二、Token

5.MyUserDetailService

6.KeyPairController

7.TokenConfig

8.WebSecurityConfig

9.ResourceServerConfig

10.AuthorizationServerConfig

四、user-service模块与feign模块

五、gateway模块资源服务器

一、项目目录

feign：远程接口调用

Gateway：资源服务器

Oauth2：授权服务器

user-service：普通资源

二、Token

对于Token采用非对称加密，因此到 java 的 bin 目录下打开 cmd，执行以下命令，生成 jwt.jks

keytool -genkey -alias jwt -keyalg RSA -keystore jwt.jks

将其复制到 oauth2 的 resource 目录下，

三、授权服务器oauth

3.OauthApp启动类

@SpringBootApplication
@EnableFeignClients(basePackages = "com.white.feign.client")
@EnableDiscoveryClient
public class OauthApp
{
    public static void main( String[] args )
    {
        SpringApplication.run(OauthApp.class,args);
    }
}

4.DiyUserDetails

package com.white.oauth2.model;

import com.white.feign.model.User;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.util.StringUtils;

import java.util.ArrayList;
import java.util.Collection;
import java.util.List;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class DiyUserDetails extends User implements UserDetails {
    private String username;
    private String password;

    private List<GrantedAuthority> authorities;//授权的
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return authorities;
    }

    @Override
    public String getPassword() {
        return password;
    }

    @Override

        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }
}

5.MyUserDetailService

这里的UserFeign是在feign模块下定义的

import com.white.feign.model.User;
import com.white.oauth2.model.DiyUserDetails;
import lombok.extern.slf4j.Slf4j;

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.List;

/**
 * 作用：

 */
@Slf4j
@Service
public class MyUserDetailService implements UserDetailsService {

    @Autowired
    UserFeign userFeign;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        log.info("********开始loadUserByUsername********");
        User user = userFeign.findUser_ByUsername(username);
        if (user==null) throw new UsernameNotFoundException(username);
        List<GrantedAuthority> grantedAuthorities = AuthorityUtils
                .commaSeparatedStringToAuthorityList(user.getIdentity());
        DiyUserDetails details=new DiyUserDetails();
        details.setUsername(username);
        details.setPassword(user.getPassword());
        details.setAuthorities(grantedAuthorities);
        log.info("查询到user为"+user.getUsername()+" 密码"+user.getPassword());
        return details;
    }
}

11.授权码模式说明与创建数据表

在这里，授权码模式是基于数据库的，而不是基于内存的，如果基于内存需要写死，这不符合灵活性的要求，所以上面的授权码认证都是基于数据库的，而在上面的application我们已经指定数据库的地址，接下来在指定的数据库中 创建两个数据表 就行，oauth会自动到数据库中找到指定两个数据表名称，并对其进行操作。

CREATE TABLE `oauth_client_details` (
  `client_id` VARCHAR(256) CHARACTER SET utf8 NOT NULL COMMENT '客户端唯一标识ID',
  `resource_ids` VARCHAR(256) CHARACTER SET utf8 DEFAULT NULL COMMENT '客户端所能访问的资源id集合',
  `client_secret` VARCHAR(256) CHARACTER SET utf8 DEFAULT NULL COMMENT '客户端访问密匙',
  `scope` VARCHAR(256) CHARACTER SET utf8 DEFAULT NULL COMMENT '客户端申请的权限范围',
  `authorized_grant_types` VARCHAR(256) CHARACTER SET utf8 DEFAULT NULL COMMENT '客户端授权类型',
  `web_server_redirect_uri` VAR`pay_system`CHAR(256) CHARACTER SET utf8 DEFAULT NULL COMMENT '客户端的重定向URI',
  `authorities` VARCHAR(256) CHARACTER SET utf8 DEFAULT NULL COMMENT '客户端所拥有的权限值',
  `access_token_validity` INT(11) DEFAULT NULL COMMENT '客户端access_token的有效时间(单位:秒)',
  `refresh_token_validity` INT(11) DEFAULT NULL,
  `additional_information` VARCHAR(4096) CHARACTER SET utf8 DEFAULT NULL COMMENT '预留的字段',
  `autoapprove` VARCHAR(256) CHARACTER SET utf8 DEFAULT NULL COMMENT '是否跳过授权(true是，false否)',
  PRIMARY KEY (`client_id`)
) ENGINE=INNODB DEFAULT CHARSET=utf8mb4 COMMENT='客户端授权表'

CREATE TABLE `oauth_code` (
`create_time` TIMESTAMP(0) NOT NULL DEFAULT CURRENT_TIMESTAMP,
`code` VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`authentication` BLOB NULL,
INDEX `code_index`(`code`) USING BTREE
) ENGINE = INNODB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = COMPACT;

并且新增一条oauth_client_details表的测试数据：client_secret的明文：111

client_id	resource_ids	client_secret
123	USER	$2a$10$1fAQjm5L.1a52uYklwiIMOKgZpye2ctD6Wv/V1Er8LWh1uyv1wRDG

scope	authorized_grant_types	web_server_redirect_uri	authorities	access_token_validity
all	authorization_code,refresh_token	http://localhost:10000	null	7200

refresh_token_validity	additional_information	autoapprove
null	null	true

12.测试

到这里，授权服务器就做好了，我们可以进行测试，注意：在数据表中的测试数据跟请求的链接相关：

（1）获取授权码

输入以下地址（该地址的相关信息跟数据表必须保持一致），自动跳转到login路径下

http://localhost:8101/uaa/oauth/authorize?client_id=123&response_type=code&scop=all&redirect_uri=http://localhost:10000

输入用户名和密码，这里是指你自己的微服务中的用户模块，输入后会通过远程调用UserFeign中指定的服务模块，其下的指定接口。也就是说，在做授权服务器outh2之前，你自己得用user模块，做一个简单的接口即可，查询数据库中指定的用户名
登录成功后就会跳转到指定的重定向路径，并在其尾部有着code参数，即授权码

（2）获取令牌

接下来将授权码代入该地址，来 获取令牌 token

这里的access_token是我们去请求资源时使用的token，而refresh_token只有在我们需要刷新token的时候才用得到。

（3）检查令牌

可以拿着access_token值去以下地址 检查令牌 ，得到令牌中包含的数据

http://localhost:8101/uaa/oauth/check_token?token=eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsiVVNFUiJdLCJ1c2VyX25hbWUiOiIxMTEiLCJzY29wZSI6WyJhbGwiXSwiZXhwIjoxNjg1NjI5MTU4LCJhdXRob3JpdGllcyI6WyJhZG1pbiJdLCJqdGkiOiJjMlVWSHhPekR6TjFvd3pDMjJRazQwZEktTFEiLCJjbGllbnRfaWQiOiIxMjMifQ.eNpZ9hjAP8MpWIVYzlVeBYhqAbBI9MU5yH8m1kc8EpnCERJtR9cdTbe-1YtqYDFrpgMYpxU2qW8OQDXr74FKj75CCB6Ik-411sGU91Ue7PSa_GKDWujT-0eJavDmDPGRKxS1lhgNdXL1BXGgS38miSa_tNnDoPOx_bydte-Mhi9m9PGBPCyF3taXXV_ARyzBXu183S5Dmv8B_CBNrAk6o7AJPBBBDyNq_puIzR_-HviOHVVsfb1-4qk8wXinS8dZMSJGycay4DKIS7PX8So1IWdXbr4l6SEddFQpnUJ70Af-zNtsFoWUIw_udv4YUZjSlW0IrjqEpXmv2rkGjYMlbQ

（4）刷新令牌

当令牌过期时，拿着refresh_token去以下地址 刷新令牌，即可拿到新的令牌token

http://localhost:8101/uaa/oauth/token?grant_type=refresh_token&refresh_token=eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsiVVNFUiJdLCJ1c2VyX25hbWUiOiIxMTEiLCJzY29wZSI6WyJhbGwiXSwiYXRpIjoicjhrWWZEcjFDWTFQS0Y2RkZqWTAwMUNia29ZIiwiZXhwIjoxNjg1NzA2NzQyLCJhdXRob3JpdGllcyI6WyJhZG1pbiJdLCJqdGkiOiJhNjNGVkV4N3RHX194UXJDQi05YnBmUWxWakUiLCJjbGllbnRfaWQiOiIxMjMifQ.arUqGU9gpyjZ3g4RsaJDtHHq7jDUgjTfdHwpzdWydM4v7kmvusYb_E9NV7It9GkcRwdpFZBYELaUgM2VIbmon6pMC1TE7LZXb44anSRcUYI8OfiYoSQ8XiJlY8CgNC9wrspWLkw4fXypGUUDUSY6yVS3l_8-kkVi0-EirBFVzNq0rBjlWr1mhGdHZib7JLqPfAdIqC0MDYhXgv4v0ikthkTjz1iDQEDVpJYpx9QXmITnxXCxFtKTSNluzv7M8gJJaJophV1jGF4A6Q8Kt2U_dmxRd07AUSb4dCyik_LOhATPhYYSp9aP7DLnF9bU0u_3_ocp90dxXy3GJwRLQrQ-rQ&client_id=123&client_secret=111

四、user-service模块与feign模块

由于user-service模块跟feign模块没有涉及到oauth2，也没有导入相关依赖包。

user-service模块作为一个普通的资源模块，feign模块也只是远程调用了user-service模块中的根据用户名查询用户信息给上面的outh2模块而已。

所以，这不是该文章的重点，故不做展示。

五、gateway模块资源服务器

到此，我们的授权管理器已经结束了，资源服务器在实际开发有两种实现方式：

（1）gateway做网关转发，不做资源服务器，由各个微服务模块自己去做资源服务器；

（2）gateway做网关转发并且做资源服务器。

前者方案使得每一个微服务模块都需要导入oauth2相关依赖，并且做处理，过于繁琐且耦合高。

所以本文章在接下来会采用后者方案进行介绍，也就是文章的重点，并且会介绍到如何解决通过gateway去认证授权，跳转到oauth2认证授权后，跳转不回或重定向不到gatway的bug。

至于我们的gateway模块，会放在下一个文章进行介绍，文章地址将在评论区中展示。

最后，祝大家六一儿童节快乐~~~~~，谁还不是一个宝宝呢！！！
