Organize errors in Java simulation http request

Author：Eve Cole Update Time：2025-08-22 11:32:01

When Java simulates http request, an error, code, and error details are reported as follows:

Configuration.xml

 <?xml version="1.0" encoding="UTF-8"?><system> <!--Request url--> <category name="url" description="Indicator URL related configuration"> <item name="volumenormUrl" value="10.150.33.154:8080/getInfo/getUser" description="Temporary URL address"></item> </category></system>

Java code

 String url = Configuration.getString("url.volumenormUrl"); try { log.info("===================={}",url); String responseString = HttpUtil.doGet(url); log.info("crmLoginUrl responseString {} {}", url, responseString); return JsonResponse.success(); } catch (WXException e) { log.error("crmLogin fail... {}, e = {} ", e.getMessage(), e); e.printStackTrace(); return JsonResponse.failure("fail"); }

Error code:

I searched Baidu and found many useless articles. Later, I searched on Bing and found the root cause. I must http:// in front of the value in configuration.xml, otherwise I will report an error~ Everyone gave up Baidu, which is too scammed.
