分布式系统Spring Cloud+Spring Security+OAuth2.0+JWT+Eureka+Spring Gateway实现授权和认证管理

 介绍：

本项目主要介绍用户的授权认证管理在分布式系统的应用，使用的是spring-cloud-starter-oauth2

 主要实现以下功能：

1：通过用户名和密码进行鉴权，获取接口调用token

2：通过token进行资源服务器的访问

软件架构：

 

项目架构：

1:daisyday-manage-auth：oauth2.0鉴权认证服务

2:daisyday-manage-eureka：eureka注册服务，用于springcloud微服务注册

3:daisyday-manage-gateway：网关服务，使用的是Spring Cloud Gateway做路由、token认证、负载均衡

4:daisyday-service-order：资源服务，本文以订单系统为例

说明：oauth.sql 是鉴权和认证所需要的的表和数据

代码：

核心代码说明：

一、AuthorizationServer类继承AuthorizationServerConfigurerAdapter（认证服务配置适配器） 我们需要重写三个方法(不写就是用默认的, 根据需求,一般需要重写)

  【1】：@Override 
  public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
     访问安全配置。
  }
 【2】： @Override 
  public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    决定clientDeatils信息的处理服务
 }
 【3】： @Override 
   public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
     访问端点配置。tokenStroe、tokenEnhancer服务
 }

    }

     */
    public TokenEnhancerChain tokenEnhancer() {
        TokenEnhancerChain tokenEnhancerChain = new TokenEnhancerChain();
        tokenEnhancerChain.setTokenEnhancers(Arrays.asList(customTokenEnhancer, jwtAccessTokenConverter));
        return tokenEnhancerChain;
    }

    /**
     * token 令牌服务

    @Bean
    public AuthorizationServerTokenServices tokenServices() {
        DefaultTokenServices services = new DefaultTokenServices();
        services.setSupportRefreshToken(true); //支持refreshtoken

        services.setTokenEnhancer(tokenEnhancer());//token里加点信息
        return services;
    }

    @Bean
    public AuthorizationCodeServices authorizationCodeServices(DataSource dataSource) {
        return new JdbcAuthorizationCodeServices(dataSource);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security
                .tokenKeyAccess("permitAll()")
                .checkTokenAccess("permitAll()")
                .allowFormAuthenticationForClients();
    }
}

二、MyUserDetailsServiceImpl实现UserDetailsService接口。希望用户的信息来自数据库，而不是写死的，所以我们就需要实现UserDetailsService接口

package com.daisyday.manage.auth.service;


import com.daisyday.manage.auth.dao.db1.UserInfoDao;
import com.daisyday.manage.auth.entry.UserInfo;
import org.springframework.beans.factory.annotation.Autowired;
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;

/**
 * 希望用户的信息来自数据库，而不是写死的，所以我们就需要实现UserDetailsService接口
 */
@Service
public class MyUserDetailsServiceImpl implements UserDetailsService {


    @Autowired
    private UserInfoDao userInfoDao;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        UserInfo userInfo=userInfoDao.selectByUserName(username);
        if(userInfo==null){
            throw new UsernameNotFoundException("username or password error");
        }
        String[] permissionArray = new String[1];
        permissionArray[0]="admin";
        // 将用户名称/用户密码以及用户拥有的权限放入UserDetails中
        UserDetails userDetails = User.withUsername(username)
                                      .password(userInfo.getPassword())
                                      .authorities(permissionArray)
                                      .build();
        return userDetails;
    }


}

三、TokenStoreConfig自定义生成access_token的类型和access_token的存储位置

可以看到access_token有五种生成和存储实现，本项目使用的是JwtTokenStore

package com.daisyday.manage.auth.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.oauth2.provider.token.DefaultAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.DefaultUserAuthenticationConverter;
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;

/**
 * token的保存方式
 *
 * @author DaisyDay
 */
@Configuration
public class TokenStoreConfig {

    private static final String SIGNING_KEY = "auth123456";

    @Autowired
    private UserDetailsService userDetailsService;

    @Bean
    public TokenStore tokenStore() {
        return new JwtTokenStore(accessTokenConverter());
    }

    @Bean
    public JwtAccessTokenConverter accessTokenConverter() {
        JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
        DefaultAccessTokenConverter tokenConverter = new DefaultAccessTokenConverter();
        DefaultUserAuthenticationConverter userTokenConverter = new DefaultUserAuthenticationConverter();

        userTokenConverter.setUserDetailsService(userDetailsService);
        tokenConverter.setUserTokenConverter(userTokenConverter);
        jwtAccessTokenConverter.setAccessTokenConverter(tokenConverter);
        /**
         * 对称秘钥，资源服务器使用该秘钥来验证
         */
        jwtAccessTokenConverter.setSigningKey(SIGNING_KEY);
        return jwtAccessTokenConverter;
    }
}

四、MyAuthenticationProvider实现AuthenticationProvider接口来进行自定义认证

package com.daisyday.manage.auth.config;

import com.daisyday.manage.auth.service.MyUserDetailsServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.stereotype.Component;

import java.util.Collection;

/**
 * AuthenticationProvider方式来进行自定义认证
 */
@Component
public class MyAuthenticationProvider implements  AuthenticationProvider {
    @Autowired
    private MyUserDetailsServiceImpl authUserDetailsService;

    /**
     * 获取表单提交的信息
     * @param authentication
     * @return
     * @throws AuthenticationException
     */
    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        Object credentials = authentication.getCredentials();
        String name = authentication.getName();
        Object principal = authentication.getPrincipal();
        //获取用户信息
        UserDetails user = authUserDetailsService.loadUserByUsername(name);
        //获取用户权限信息
        Collection authorities = user.getAuthorities();
        return new UsernamePasswordAuthenticationToken(user, principal, authorities);
    }

    /**
     * @Description 如果该AuthenticationProvider支持传入的Authentication对象，则返回true
     * @param authentication
     * @return
     */
    @Override
    public boolean supports(Class authentication) {
        return true;
    }
}
