阿里巴巴网站导航怎么做公司建立网站的步骤
使用WxJava微信开发时，调用接口获取access_token，如果多个服务部署，就需要使用到缓存来保存access_token以达到重复利用，WxJava 也提供了相关的实现类WxMaRedisConfigImpl，但是这个是基于jedis客户端的实现，最新版本的springboot-redis都开始采用lettuce客户端进行连接了，所以我们只能自己手动实现一个类似于WxMaRedisConfigImpl的类

WxMaLettuceRedisConfigImpl基于lettuce的工具类
package cn.shiyue.config.ma;import cn.binarywang.wx.miniapp.config.impl.WxMaDefaultConfigImpl;
import org.apache.commons.lang3.ObjectUtils;
import org.springframework.data.redis.core.StringRedisTemplate;import java.util.concurrent.TimeUnit;public class WxMaLettuceRedisConfigImpl extends WxMaDefaultConfigImpl {private StringRedisTemplate stringRedisTemplate;private static final String ACCESS_TOKEN_KEY = "wa:access_token:";private String accessTokenKey;public WxMaLettuceRedisConfigImpl(StringRedisTemplate stringRedisTemplate){this.stringRedisTemplate = stringRedisTemplate;}/*** 每个公众号生成独有的存储key.*/@Overridepublic void setAppid(String appId) {super.setAppid(appId);this.accessTokenKey = ACCESS_TOKEN_KEY.concat(appId);}@Overridepublic String getAccessToken() {return stringRedisTemplate.opsForValue().get(accessTokenKey);}@Overridepublic boolean isAccessTokenExpired() {Long expireTime = stringRedisTemplate.getExpire(accessTokenKey);if (ObjectUtils.isEmpty(expireTime)) {return true;}// 到期时间小于2秒就算作过期了，就重新调用接口获取return expireTime < 2;}@Overridepublic synchronized void updateAccessToken(String accessToken, int expiresInSeconds) {stringRedisTemplate.opsForValue().set(accessTokenKey, accessToken, expiresInSeconds - 200, TimeUnit.SECONDS);}@Overridepublic void expireAccessToken() {stringRedisTemplate.expire(accessTokenKey, 0, TimeUnit.SECONDS);}@Overridepublic long getExpiresTime() {Long expire = stringRedisTemplate.getExpire(accessTokenKey);return expire == null ? 0 : expire;}@Overridepublic void setExpiresTime(long expiresTime) {stringRedisTemplate.expire(accessTokenKey, expiresTime, TimeUnit.SECONDS);}

}
还有一种方式在WxMaConfiguration 文件中配置，这个WxMaRedisBetterConfigImpl类需要高版本的weixin-java-miniapp的jar
@Autowired
private StringRedisTemplate stringRedisTemplate;
// 方式二才需要用上
@Bean
public WxRedisOps getWxRedisOps() {
return new RedisTemplateWxRedisOps(stringRedisTemplate);
}
// 方式一：自己实现一个lettuce的redis配置对象
WxMaDefaultConfigImpl config = new WxMaLettuceRedisConfigImpl(stringRedisTemplate);
// 方式二: 使用wxRedisOps对象来包装redis连接
// WxMaDefaultConfigImpl config = new WxMaRedisBetterConfigImpl(getWxRedisOps(), "wa:access_token:");
