1.我們有一個專案，原本是ssm的，我升級成了springboot的，可以啟動，沒啥問題；
2.然后負責人讓我把這個專案的配置全部交給我們自己搭建的apollo管理，我自己單獨寫了個專案，發現沒問題，可以實時動態地讀取和修改組態檔
3.但是我把自己的專案交給apollo管理的時候，啟動的時候報錯，我百度一下那些錯，有人說大概是類加載順序的問題，具體我也不太清楚，我把組態檔給apollo管理后，專案啟動的時候報錯，就在一開始，單點登錄那里報錯，我發現單點登錄的類里面用了大量的靜態變數和靜態代碼塊，會不會是這個有影響？下面是報錯的資訊

uj5u.com熱心網友回復：
如果需要看其他地方的可以留言，太難了，謝謝大哥們uj5u.com熱心網友回復：
負責人說他也不知道行不行，他說他不關心，要是問別人，可以的話，我周末就過來加班uj5u.com熱心網友回復：
這個是報錯的那個service類，里面就有大量靜態變數和靜態代碼塊
@Service("systemPlatformWSService")
public class SystemPlatformWSService {
static SystemPlatformPortProxy proxy = new SystemPlatformPortProxy();
//static String spxtid=CommonPropertites.SPXT_ID.trim();
// static String xtid="abcd";
static String authenticationCode = "";
static {
//String url="http://149.0.0.228:8040/ws/ws-sp";
String url = PropertyUtil.getConfig("XTPT_WEBSERVICE_URL",null);
proxy.setEndpoint(url);
}
private Gson gson = new Gson();
public String getUserTreeJson(GetUserTreeRequest request) {
try {
requestNullValue(request);
GetUserTreeResponse response = proxy.getUserTree(request);
String json = base64ToJSONString(response.getBase64String());

}
return null;

這個專案我只負責升級，這些類是做啥的具體我也不是很清楚，注釋都沒有，誰寫的都不知道
