使用jar包：

<!--commons-httpclient--> <dependency> <groupId>commons-httpclient</groupId> <artifactId>commons-httpclient</artifactId> <version>3.1</version> </dependency> </dependencies>

代码：

try { String postURL = "http://*.*.*.*:8080/cjs/ad"; PostMethod postMethod = null; postMethod = new PostMethod(postURL) ;
　　　　　　　//添加请求头数据 postMethod.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8") ; //参数设置，，需要注意的就是里边不能传NULL，要传空字符串 NameValuePair[] data = { new NameValuePair("_ArgStr1","*"),
new NameValuePair("_ArgStr2","*") }; postMethod.setRequestBody(data); org.apache.commons.httpclient.HttpClient httpClient = new org.apache.commons.httpclient.HttpClient(); int response = httpClient.executeMethod(postMethod); // 执行POST要领 String result = postMethod.getResponseBodyAsString() ; System.out.println(response); System.out.println(result); } catch (Exception e) { // logger.info("请求异常"+e.getMessage(),e); throw new RuntimeException(e.getMessage()); }

Http发送post(x-www-form-urlencoded)请求
