RestTemplate交換法導致彈簧啓動應用程序現在掛每個然後

我有這個功能，通過RestTemplate.exchange（）獲取的對象...RestTemplate交換法導致彈簧啓動應用程序現在掛每個然後

private MatchList getRankedHistoryFromAccountId(long accountId) { 

    String url = HTTPS + Region.valueOf(region.toUpperCase()).getServerURL() + URL_PREFIX + RiotAPIEndpoint.values()[6].getServiceURL(accountId) + API_KEY; 
    RestTemplate template = new RestTemplate(); 
    try { 
     System.out.println("Exchanging!"); 
     MatchList matchList = template.exchange(url, HttpMethod.GET, null, MatchList.class).getBody(); 
     return matchList; 
    } 
    catch (HttpClientErrorException hcee) { 
     switch (hcee.getRawStatusCode()) { 
      case 404: 
       return null; 
      default: 
       try { 
        hcee.printStackTrace(); 
        Thread.sleep(1000); 
        return getRankedHistoryFromAccountId(accountId); 
       } 
       catch (InterruptedException e) { 
        e.printStackTrace(); 
       } 
     } 
    } 
    return null; 
}

這工作，時間約99％。我會說這個功能的1/100調用導致「交換！」打印出來然後程序就掛起來了。我一直在這個問題上停留了一週，在網上找不到任何東西來幫助我解決問題。

編輯：這裏是爲最後 2 GET請求調試消息：

是端點本地還是在互聯網上？如果你使用curl或瀏覽器打開url，它是否掛起？如果你想讓它優雅地失敗而不是懸掛，那麼可能會設置超時。 https://stackoverflow.com/questions/32983328/setting-timeouts-in-spring-rest-template –

@MattR，哇我不知道它默認情況下有無限的超時...我會嘗試看看如果它有效。謝謝。 – Nuradin

看起來沒有用。同樣的問題仍然存在。 – Nuradin

我理解了它得益於@AbhijitSarkar幫助。

調試狀態碼後，我發現我每隔一段時間都會返回5xx狀態碼。正如您在OP中看到的那樣，只有客戶端異常被捕獲。 5xx狀態碼在這裏沒有被捕獲，因爲它們是服務器例外。

catch (HttpServerErrorException hsee) { 
     switch(hsee.getRawStatusCode()) { 
      default: 
       try { 
        hsee.printStackTrace(); 
        Thread.sleep(1000); 
        return getSummonerInformationFromAccountId(accountId); 
       } 
       catch (InterruptedException e) { 
        e.printStackTrace(); 
       } 
     } 
    }

另一個帶有HttpServerErrorException的catch塊可以解決這個問題。很明顯，你會想要添加更多的案例到交換機，並有一個很好的策略來處理至少最常見的（500,503等）
