當喚醒httpClient.execute調用其餘Web服務時,我從主題中收到錯誤。我讀了兩個有趣的線索,它們與我的情況有些相似。在這兩個線程中,我相信通過增加websphere中的緩衝區8 Liberty配置文件可能會幫助我更好地描述問題,但我不知道在WAS 8.5 Liberty配置文件(不存在管理控制檯)中增加它的位置。我不知道它是否相關,但我放置了(1)用於指導我的線程,這是我在(2)applicationContext.xml中唯一重要的指令,(3)mvc-dispatcher-servlet.xml,( 4)用於其他Web服務的客戶端和(5)POM.xml。可以猜想這些庫有一些問題,因爲這些項目在我將其轉換爲Maven Project之前完全正常工作。有人可以告訴我,如果我錯過了POM中的一些操作?無法設置標題。響應已經提交 - httpClient.execute錯誤
1) WebSphere response buffering Cannot set header in JSP. Response already committed
2)
的applicationContext.xml ... 3)
MVC-調度-servlet.xml中 /WEB-INF/pages/ .JSP ... 4)
@Component
public class Lo_DisplayHandler extends Lo_Handler {
HttpClient httpClient = HttpClientBuilder.create().build();
HttpPost postRequest = new HttpPost("http://localhost:8080/MHE2/log/display/last"); //lastPageUrl);
Map<String, String> map = new HashMap<String, String>(); //to map key & value
… //setting the parameters
ObjectMapper mapper = new ObjectMapper();
String strJson = mapper.writeValueAsString(map);
StringEntity input = new StringEntity(strJson);
input.setContentType("application/json");
postRequest.setEntity(input);
HttpResponse response = httpClient.execute(postRequest); //here I got the error [WARNING ] SRVE8094W: WARNING: Cannot set header. Response already committed.
