创建bootstrap.yml文件

代码如下（示例）：

#bootstrap.yml优先级比application.yml优先级高
spring:
  #prefix−{spring.profile.active}.${file-extension}
  #nacos会根据当前环境去拼接配置名称查找相应配置文件，
  #示例：{spring.application.name}-{spring.profiles.active}-{spring.cloud.nacos.config.file-extension}
  #获取到值：nacos-autoconfig-service-dev.yml
  profiles:
    #开发环境dev，测试环境test，生产环境prod
    active: dev
  application:
    #配置应用的名称，用于获取配置
    name: security-oauth2
  main:
    allow-bean-definition-overriding: true
  cloud:
    nacos:
      discovery:
        # 服务注册地址
        server-addr: ip:8848
      config:
        #nacos配置中心地址
        server-addr: ip:8848
        #配置中心的命名空间id
        namespace: 9e50b6d9-6c3d-4e7a-b701-10f085e4b98d
        #配置分组，默认没有也可以
        group: DEFAULT_GROUP
        #配置文件后缀，用于拼接配置配置文件名称，目前只支持yaml和properties
        file-extension: yaml
        #配置自动刷新
        refresh-enabled: true
        #配置文件的前缀，默认是application.name的值，如果配了prefix，就取prefix的值
        #prefix: nacos-autoconfig-service-${spring.profile.active}
        # 配置编码
        encode: UTF-8
        username: nacos
        password: nacos

auth:
  jwt:
    keyPairName: jwt.jks
    keyPairAlias: jwt
    keyPairSecret: 123456
    keyPairStoreSecret: 123456

修改application.properties文件

server.port=8807

创建一个空的config.properties文件

在这里插入图片描述

创建jwt.jks文件

在这里插入图片描述

# Keytool 是一个java提供的证书管理工具
#    -alias：密钥的别名 
#    -keyalg：使用的hash算法 
#    -keypass：密钥的访问密码 
#    -keystore：密钥库文件名，jwt.jks -> 生成的证书 
#    -storepass：密钥库的访问密码
keytool -genkeypair -alias jwt -keyalg RSA -keypass 123456 -keystore jwt.jks -storepass 123456

# 查询证书
keytool -list -keystore jwt.jks

把生成的文件复制到项目的resource目录下面
在这里插入图片描述在这里插入图片描述

修改SpringCloudSecurityOauth2DemoApplication

代码如下（示例）：

package com.example.springcloudsecurityoauth2demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@EnableDiscoveryClient
@SpringBootApplication
public class SpringCloudSecurityOauth2DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudSecurityOauth2DemoApplication.class, args);
    }

}

创建数据库表结构

代码如下（示例）：

#官方的sql: https://github.com/spring-projects/spring-security-oauth/blob/master/spring-security-oauth2/src/test/resources/schema.sql

CREATE TABLE `clientdetails` (
  `appId` varchar(128) NOT NULL,

@Component
public class UserServiceHystrix implements UserInfoFeignService {


    @Override
    public ResultData<AppUserinfoEntity> getUserinfoById(String userId) {
        return null;
    }

    @Override
    public ResultData<AppUserinfoEntity> getUserByUserName(String username) {

      return claims.getExpiration().before(new Date());
    }
}

验证Spring Cloud Security Oauth2是否工作

首先要获取access_token，然后根据access_token认证授权

授权码模式

获取授权码

浏览器请求：http://127.0.0.1:8807/oauth/authorize?response_type=code&client_id=client
重定向为：http://127.0.0.1:8807/login
输入
用户名：liaozhiwei
密码：123456
如下图（示例）：
在这里插入图片描述

授权登录之后会进行回调获取授权码

如下图（示例）：
在这里插入图片描述

填入授权码code获取获取access_token

发起请求：http://127.0.0.1:8807/oauth/token?grant_type=authorization_code&client_id=client&client_secret=client_secret&code=12PVmF
如下图（示例）：

创建bootstrap.yml文件

代码如下（示例）：

#bootstrap.yml优先级比application.yml优先级高
spring:
  #prefix−{spring.profile.active}.${file-extension}
  #nacos会根据当前环境去拼接配置名称查找相应配置文件，
  #示例：{spring.application.name}-{spring.profiles.active}-{spring.cloud.nacos.config.file-extension}
  #获取到值：nacos-autoconfig-service-dev.yml
  profiles:
    #开发环境dev，测试环境test，生产环境prod
    active: dev
  application:
    #配置应用的名称，用于获取配置
    name: security-oauth2-sso-client
  main:
    allow-bean-definition-overriding: true
  cloud:
    nacos:
      discovery:
        # 服务注册地址
        server-addr: ip:8848
      config:
        #nacos配置中心地址
        server-addr: ip:8848
        #配置中心的命名空间id
        namespace: 9e50b6d9-6c3d-4e7a-b701-10f085e4b98d
        #配置分组，默认没有也可以
        group: DEFAULT_GROUP
        #配置文件后缀，用于拼接配置配置文件名称，目前只支持yaml和properties
        file-extension: yaml
        #配置自动刷新
        refresh-enabled: true
        #配置文件的前缀，默认是application.name的值，如果配了prefix，就取prefix的值
        #prefix: nacos-autoconfig-service-${spring.profile.active}
        # 配置编码
        encode: UTF-8
        username: nacos
        password: nacos

修改application.properties文件

代码如下（示例）：

server.port=8808
server.servlet.session.cookie.name=OAUTH2-CLIENT-SESSIONID${server.port}
oauth2-server-url: http://127.0.0.1:8807
security.oauth2.client.client-id=client
security.oauth2.client.use-current-uri=false
security.oauth2.client.client-secret=client_secret
security.oauth2.client.user-authorization-uri=${oauth2-serverurl}/oauth/authorize
security.oauth2.client.access-token-uri=${oauth2-server-url}/oauth/token
security.oauth2.resource.jwt.key-uri=${oauth2-server-url}/oauth/token_key

修改SpringCloudSecurityOauth2SsoClientDemoApplication

代码如下（示例）：

package com.luban.oauth2ssoclientdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.security.oauth2.client.EnableOAuth2Sso;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
/*@EnableOAuth2Sso单点登录的原理简单来说就是：标注有@EnableOAuth2Sso的OAuth2 Client应用在通过某种
OAuth2授权流程获取访问令牌后（一般是授权码流程），通过访问令牌访问userDetails用户明细这个受保护资源服务，
获取用户信息后，将用户信息转换为Spring Security上下文中的认证后凭证Authentication，从而完成标注有
@EnableOAuth2Sso的OAuth2 Client应用自身的登录认证的过程。整个过程是基于OAuth2的SSO单点登录*/
@EnableOAuth2Sso
@EnableDiscoveryClient
public class SpringCloudSecurityOauth2SsoClientDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudSecurityOauth2SsoClientDemoApplication.class, args);
    }

}

创建UserController

代码如下（示例）：

package com.luban.oauth2ssoclientdemo.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @Author: liaozhiwei
 * @Description: TODO
 * @Date: Created in 09:24 2022/8/24
 */
@RestController
@RequestMapping("/user")
public class UserController {

    @RequestMapping("/testCallback")
    public Object testCallback() {
        return "";
    }
}

校验请求是否有到授权服务器进行授权

浏览器发起请求：http://localhost:8808/user/getUserByAuthentication
重定向到登录页面：
输入
用户名：liaozhiwei
密码：123456
如下图（示例）：
在这里插入图片描述

授权登录之会进行回调，返回授权码

如下图（示例）：
在这里插入图片描述

拿到授权码获取access_token

http://127.0.0.1:8807/oauth/token?grant_type=authorization_code&client_id=client&client_secret=client_secret&code=fj7ivJ
如下图（示例）：
在这里插入图片描述
到这里为止，可以发现单点登录也基本校验成功了
