当前使用的版本：

just_auth_version = '1.16.6'just_auth_starter_version = '1.4.0'
"me.zhyd.oauth:JustAuth:${just_auth_version}", //多渠道登录"com.xkcoding.justauth:justauth-spring-boot-starter:${just_auth_starter_version}" //启动器

在JustAuth整合过程中，遇到两个功能扩展：
1）JustAuth默认使用sping-data-redis作为缓存接口，当前系统没有使用该redis驱动，由于已经使用了redission，不希望引入更多的架构。故需要扩展JustAuthCache接口
2）JustAuth配置的登录回调地址必须写完整的域名。本着从哪里来，回哪里去的原则，回调的域名地址，95%需求都会跟请求的域名地址一致。这样只需要在请求时获得请求的域名地址即可，不用在配置文件里额外配置。让配置文件的redirect-uri真正成为URI而不是URL

自定义缓存

自定义缓存按照文档的扩展即可，项目使用redission，如下定义一个CacheBean

package org.ccframe.commons.auth;import me.zhyd.oauth.cache.AuthStateCache;import org.ccframe.config.GlobalEx;import org.redisson.api.RBucket;import org.redisson.api.RedissonClient;import org.redisson.client.codec.StringCodec;import java.util.concurrent.TimeUnit;/** * JustAuth三方登录缓存管理. * @author Jim 2024/03/08 */public class CcAuthStateCache implements AuthStateCache {private RedissonClient redissonClient;public CcAuthStateCache(RedissonClient redissonClient){this.redissonClient = redissonClient;}/** * 存入缓存 * * @param key 缓存key * @param value 缓存内容 */@Overridepublic void cache(String key, String value) {RBucket bucket = redissonClient.getBucket(GlobalEx.CACHEREGION_THIRD_AUTH + key);bucket.set(value, 10, TimeUnit.MINUTES); // 10分钟还无法三方绑定的登录，则无法进行绑定}/** * 存入缓存 * * @param key 缓存key * @param value 缓存内容 * @param timeout 指定缓存过期时间（毫秒） */@Overridepublic void cache(String key, String value, long timeout) {RBucket bucket = redissonClient.getBucket(GlobalEx.CACHEREGION_THIRD_AUTH + key, StringCodec.INSTANCE);bucket.set(value, timeout, TimeUnit.MILLISECONDS);}/** * 获取缓存内容 * * @param key 缓存key * @return 缓存内容 */@Overridepublic String get(String key) {RBucket bucket = redissonClient.getBucket(GlobalEx.CACHEREGION_THIRD_AUTH + key, StringCodec.INSTANCE);return bucket.get();}/** * 是否存在key，如果对应key的value值已过期，也返回false * * @param key 缓存key * @return true：存在key，并且value没过期；false：key不存在或者已过期 */@Overridepublic boolean containsKey(String key) {return redissonClient.getBucket(GlobalEx.CACHEREGION_THIRD_AUTH + key).isExists();}}

实现真正的REDIRECT URI

先看看实现后的效果，整合后，CcFrame的公共配置只需要如下配置：

justauth:enabled: false #原来的关闭掉，因为自己写了个新的CcAuthRequestFactory,使用下面的开关cc-enabled: truecache:type: customtype:QQ: #前台登录client-id: ${app.third-oauth.QQ.client-id:}client-secret: ${app.third-oauth.QQ.client-secret:}redirect-uri: /api/common/thirdOauthCallback/qqunion-id: falseGITEE: #后台登录client-id: ${app.third-oauth.GITEE.client-id:}client-secret: ${app.third-oauth.GITEE.client-secret:}redirect-uri: /admin/common/thirdOauthCallback/giteeDINGTALK: #后台登录client-id: ${app.third-oauth.DINGTALK.client-id:}client-secret: ${app.third-oauth.DINGTALK.client-secret:}redirect-uri: /admin/common/thirdOauthCallback/dingtalk

redirect-uri不关心回调地址从哪里来，这样便省去了不同项目域名地址之间差异，我只关心URI

而项目里的配置则更简单：

app:third-oauth:GITEE:client-id: ??client-secret: ??

即可针对不同的项目及环境实现接入。

扩展点如下：
针对不支持URI的问题，本打算extendAuthRequestFactory的，结果发现大部分方法都private了，不方便扩展。再检查下用法发现引入的地方是在用户代码部分，因此索性复制了重写了

这样一来，实际调用的时候，AutowireCcAuthRequestFactory而不是AuthRequestFactory。而在get方法的时候，增加了requestBaseUrl调用用来自动添加前缀地址。requestBaseUrl则是从Controller请求自动从前端请求抓取而来：

@Autowiredprivate CcAuthRequestFactory factory;@GetMapping(value = "thirdOauth")@ApiOperation(value = "三方登录并跳转")@SneakyThrowspublic void thirdOauth(String type,@ApiIgnore RequestSite adminSite, HttpServletResponse response){ //跳转三方登录，换取code等AuthRequest authRequest = factory.get(type, adminSite.getRequestBaseUrl());response.setStatus(302); //支持HTTP重定向到HTTPSresponse.sendRedirect(authRequest.authorize(AuthStateUtils.createState()));}

BTW.三方登录的请求开关也被改了，使用cc-enabled而不是enabled，避免将原来的RequestFactory也自动初始化

至于RequestSite adminSite如何自动注入的请看我的另一篇文章，你注入ServletHttpRequest去实现一样。

这样便支持了前面配置文件里的直接书写URI，URL则是调用Controller的请求域名及IP：
redirect-uri: /api/common/thirdOauthCallback/qq

配置省事了，省一点算一点，优秀的系统必须是一点点简化而来的
