naocs注册中心

本人使用的是nacos 作为注册中心
nacos是阿里开源的。具有可视化页面。

子项目引包

<dependencies>
    <!--nacos-->
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
    </dependency>
</dependencies>

配置文件

spring:
  application:
    name: gateway
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848

duboo

配置

dubbo:
  application:
    name: ${spring.application.name}
  provider:
    timeout: 5000
  consumer:
    check: false #不检查服务是否启动
    timeout: 5000
  registry:
    address: nacos://${spring.cloud.nacos.discovery.server-addr}
    check: false #不检查注册表
  protocol:
    name: dubbo
    port: 20881
  scan:
    base-packages: com.*.*.service

zuul 网关

超时问题太烦了，感觉和spring 框架就不匹配。难受。本人已经放弃了

怎么解决跨域问题呢，因为zuul 是基于servlet的。直接在WebMvcConfig解决就行了

@Configuration
@EnableWebMvc
public class WebMvcConfig implements WebMvcConfigurer {
	/* 解决跨域问题 */
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        // 设置允许跨域的路径
        registry.addMapping("/**")
                //放行哪些原始域
                .allowedOrigins("*")
                //是否发送Cookie信息
                .allowCredentials(true)
                //放行哪些原始域(请求方式)
                .allowedMethods("*")
                //放行哪些原始域(头部信息)
                .allowedHeaders("*")
                // 跨域允许时间
                .maxAge(3600);
    }
}

配置

zuul:
  # host配置适用于routes 为url请求服务的路由方式,如果是service-id路由方式则配置ribbon
  host:
    connect-timeout-millis: 6000
    socket-timeout-millis: 6000
    max-per-route-connections: 2000
    max-total-connections: 10000
ribbon:
  #请求处理的超时时间 下级服务响应最大时间,超出时间消费方（路由也是消费方）返回timeout
  ReadTimeout: 5000
  #ribbon请求连接的超时时间- 限制3秒内必须请求到服务，并不限制服务处理的返回时间
  ConnectTimeout: 3000
#设置hystrix超时(Edgware版本下default配置不生效,默认超时2秒,建议hystrix超时时间>其他超时时间配置[如ribbon])
hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 5000

public class CustomConfiguration {


}

Gateway 网关

由于是Webflux 与web框架冲突。好用

配置

spring:
  cloud:
    gateway:
      globalcors:
      	#跨域解决方案
        globalcors:
        corsConfigurations:
          '[/**]':
            #这里有个allowCredentials: true这个东西是设置允许访问携带cookie的，这点一定要和前端对应！
            allowCredentials: true
            #可以填写多个域名用","隔开 例如："http://www.xiaolc.cn,https://spring.io"  "*"代表允许所有
            allowedOrigins: "*"
            allowedMethods: "*"
            allowedHeaders: "*"
     routes:
     - id: gateway

如何优雅的扩展oauth2的认证方式。

本人参考了大量的文章。后觉得使用改变原aouth2框架的情况下，扩展我们需要的图片验证码登陆。短信登陆之类的认证方式
在原创作者的代码上进行了微量的修改，使代码更加简洁易懂。认证流程也不会被调用两次或多次重复的情况。
（这里的代码不是全部的，我只将核心的贴出来，仅供诸君参考）

导包

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-security</artifactId>

    <version>1.2.60</version>
</dependency>

WebSecurityConfig 配置如下

package com.ljq.oauth2.config.basic;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.security.authentication.AuthenticationManager;

import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
@EnableGlobalMethodSecurity(securedEnabled = true, prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    //安全拦截机制（最重要）
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .formLogin()
                .and()
                .authorizeRequests()
                .antMatchers(HttpMethod.OPTIONS).permitAll()
                .anyRequest().authenticated()
        ;
    }

}

TokenConfig 的配置（作者使用jwt的token 不使用原有的短token）

package com.ljq.oauth2.config.basic;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;

    private static String signing_key = "liu_jun_qiin";

    /**

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

    @Bean
    public JwtAccessTokenConverter accessTokenConverter() {
        var converter = new JwtAccessTokenConverter();
        converter.setSigningKey(signing_key);
        return converter;
    }

}

AuthorizationServer oauth2认证的配置

首先了解一下 权限认证的过滤连。在我们需要的地方插入自定义的过滤拦截

IntegrationAuthenticationFilter 配置集成认证，用来分发我们的过滤器-例如：图片验证码登陆、短信登陆这些

}

IntegrationAuthentication 收集登陆认证信息

package com.ljq.oauth2.config.authenticationIntegrate;

import lombok.Data;

import java.util.Map;

/**

    public String getAuthParameter(String paramter) {
        String[] values = this.authParameters.get(paramter);
        if (values != null && values.length > 0) {
            return values[0];
        }
        return null;

}

IntegrationAuthenticator 认证处理配置接口

IntegrationAuthenticationContext 将认证信息储存在上下文中，集成身份验证上下文

package com.ljq.oauth2.config.authenticationIntegrate;

/**

    public static IntegrationAuthentication get(){
        return holder.get();
    }

    public static void clear(){

ouath2 如何自定义返回自己定义的格式数据，而不是 走DefaultWebResponseExceptionTranslator

看源码知道，只需要实现WebResponseExceptionTranslator类的translate 方法即可
所有自定义一个异常处理就行了

*定义一个MyWebResponseExceptionTranslator *

@Component
public class MyWebResponseExceptionTranslator implements WebResponseExceptionTranslator {

    @Override
    public ResponseEntity<?> translate(Exception e) throws Exception {
        if (e instanceof OAuth2Exception) {
            return ResponseEntity.ok(ServiceResult.failure(((OAuth2Exception) e).getHttpErrorCode() + "", e.getMessage()));
        }
        throw e;
    }

}

配置一下 AuthorizationServer（AuthorizationServerConfigurerAdapter）中的配置

@Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints
               .exceptionTranslator(myWebResponseExceptionTranslator)
        ;
    }

如何添加自定义的 jwt token扩展数据

自定义一个CustomerEnhancer

package com.ronrun.auth.config.securityOath2.token;

import com.alibaba.fastjson.JSON;
import com.ronrun.auth.pojo.vo.AuthUserVo;
import com.ronrun.common.constant.AuthConstant;
import org.springframework.security.oauth2.common.DefaultOAuth2AccessToken;
import org.springframework.security.oauth2.common.OAuth2AccessToken;
import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.security.oauth2.provider.token.TokenEnhancer;
import org.springframework.stereotype.Component;

import java.util.HashMap;
import java.util.Map;

@Component
public class CustomerEnhancer implements TokenEnhancer {

    @Override
    public OAuth2AccessToken enhance(OAuth2AccessToken oAuth2AccessToken, OAuth2Authentication oAuth2Authentication) {
        final Map<String, Object> additionalInfo = new HashMap<>();
        var user = (AuthUserVo) oAuth2Authentication.getUserAuthentication().getPrincipal();
        //用户名jwt 默然就已经加入所以无需在添加
        additionalInfo.put(AuthConstant.authUserVo, JSON.toJSONString(user));
        ((DefaultOAuth2AccessToken) oAuth2AccessToken).setAdditionalInformation(additionalInfo);
        return oAuth2AccessToken;
    }

}

认证服务 中配置

@Configuration
@EnableAuthorizationServer
public class AuthorizationServer extends AuthorizationServerConfigurerAdapter {
	@Resource
    private CustomerEnhancer customerEnhancer;

	/**
     * 功能描述:
     * 〈配置token 服务〉
     *
     * @return : org.springframework.security.oauth2.provider.token.AuthorizationServerTokenServices
     * @author : ljq-刘俊秦
     * @date : 2020/6/6 0006 下午 9:46
     */
    @Bean
    public AuthorizationServerTokenServices tokenService() {
        var service = new DefaultTokenServices();
        service.setClientDetailsService(clientDetailsService);
        service.setSupportRefreshToken(true);
        service.setTokenStore(tokenStore);
        //配置jwtToken
        var tokenEnhancer = new TokenEnhancerChain();
        tokenEnhancer.setTokenEnhancers(Arrays.asList(customerEnhancer,accessTokenConverter));
        service.setTokenEnhancer(tokenEnhancer);
        service.setAccessTokenValiditySeconds(7200); //令牌默认有效期2小时
        service.setRefreshTokenValiditySeconds(86400); //刷新令牌默认时间有效期24小时
        return service;
    }

总结

想要扩展什么登陆类型可以直接实现AbstractPreparableIntegrationAuthenticator类来处理，自己需要认证的数据。
