前端报错 invalid signature 大概原因知道应该是appid和jsapi_ticket 不匹配造成的

ApiConfig ac = new ApiConfig();
ac.setAppId(appid);
ac.setAppSecret(appSecret);
ac.setToken(token);
ApiConfigKit.putApiConfig(ac);
ApiConfigKit.setThreadLocalAppId(ac.getAppId());
JsTicket jsApiTicket = JsTicketApi.getTicket(JsApiType.jsapi);

final IAccessTokenCache accessTokenCache = ApiConfigKit.getAccessTokenCache();
String key = ac.getAppId() + ':' + JsApiType.jsapi.name();
System.out.println("缓存：key:"+key+"-"+accessTokenCache.get(key));

情景是两个不同公众号配置进这段代码 第一次运行

缓存：key:wx305749a07abae9b3:jsapi-{"errcode":0,"ticket":"sM4AOVdWfPE4DxkXGEs8VNQEivnUA2nvrGfDcsjuxGSMP1JEMidqwy1rk2GvJXqW7WcgNXcegEC5KdozslXWwg","errmsg":"ok","expiredTime":1554261635650}

缓存：key:wx583e4b51a113fd70:jsapi-{"errcode":0,"ticket":"kgt8ON7yVITDhtdwci0qeRDmZbg7ucLtvlM5YphKJIo2yzGgqZXJk6_N5QN1ipJq1wqtLcrzRxOz64Ksuzthfg","errmsg":"ok","expiredTime":1554261690543}

这时前端不会报错，appid对应一个jsapi_ticket ，但是2个小时后失效重新获取jsapi_ticket 后，两个ticket就一致了

缓存：key:wx583e4b51a113fd70:jsapi-{"errcode":0,"ticket":"sM4AOVdWfPE4DxkXGEs8VNQEivnUA2nvrGfDcsjuxGT6epDEYhlWnprIphgJfqXB7kuHMAMmpwUkB4ztZCEs7Q","errmsg":"ok","expiredTime":1554276489314}

缓存：key:wx305749a07abae9b3:jsapi-{"errcode":0,"ticket":"sM4AOVdWfPE4DxkXGEs8VNQEivnUA2nvrGfDcsjuxGT6epDEYhlWnprIphgJfqXB7kuHMAMmpwUkB4ztZCEs7Q","errmsg":"ok","expiredTime":1554271506336}

有大佬知道如何解决吗
