您好,我是按照demo项目,往下面加了个redis 缓存 accesstoken,这样有作用吗,我担心 oauth2getAccessToken每次获取的时候还是获取了一次access_token,导致我缓存的是无效的access_token
WxMpOAuth2AccessToken wxMpOAuth2AccessToken = mpService.oauth2getAccessToken(code);
String access_token = rs.get(WxEnum.access_token);
if (access_token == null || access_token == "") {
access_token = wxMpOAuth2AccessToken.getAccessToken();
rs.setWithExpireTime(WxEnum.access_token, access_token, 7140);
}
