在weblogic容器中使用Spring RestTemplate的EOF異常

Question

我在我們的服務中收到以下EOF錯誤。 這是一個在weblogic服務器中部署爲war的spring引導應用程序。

這個blo g描述了我所看到的。但我使用的RestTemplate應該是默認的HttpClientFactory而不是weblogic。有人可以解釋爲什麼，我應該怎麼做？

謝謝

我發佈的答案，因爲它會幫助其他面臨同樣問題時。

通過在restTemplate上明確設置HttpClientFactory，我能夠擺脫這個錯誤。我默認認爲，RestTemplate使用HttpClient。我無法弄清楚爲什麼我需要設置這個。但這有助於解決。

@Bean 
public RestTemplate restTemplate(){ 
    HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(); 
    RestTemplate template = new RestTemplate(factory); 
    template.setErrorHandler(new RestResponseHandler()); 
    return template; 
    } 

之前，我有

@Bean 
    public RestTemplate restTemplate(){ 
    return new RestTemplate(); 
    }
