我正在使用HTTPClient构建测试项目以测试静态服务。这是到目前为止我成功用于在GET上获得200 OK响应的代码。但是，我在.releaseConnection上遇到错误，HTTPClient文档说该错误很重要。
码：
public class Container {
public String tryGet() {
String getResult = null;
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://test.url");
try {
HttpResponse response1 = httpclient.execute(httpGet);
System.out.println(response1.getStatusLine());
getResult = response1.getStatusLine().toString();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
httpGet.releaseConnection();
}
return getResult;
}
}
运行junit测试时，出现与.releaseConnection（）相关的以下错误：

我知道代码很丑陋。我才刚刚开始。
最佳答案
在版本中添加了HttpRequestBase#releaseConnection()方法。
可能您有地狱。如果编译器没有编译错误，则可以在运行时加载该类的另一个版本。真正的原因取决于您的构建工具。如果您使用的是Maven / Gradle，则可能存在一些传递依赖。
因此，实际上HttpRequestBase#releaseConnection()方法只是将代理代理调用到AbstractExecutionAwareRequest#reset()。而AbstractExecutionAwareRequest#reset()只是取消方法的执行。可能不是您所需要的。
执行和释放httpClient资源的正确方法是关闭httpResponse，这意味着您可以在httpClient的内部threadPool中释放Thread。
private static String makeRequest(HttpUriRequest httpRequest) throws IOException {
CloseableHttpResponse httpResponse = httpClient.execute(httpRequest);
try {
HttpEntity httpEntity = httpResponse.getEntity();
StringWriter writer = new StringWriter();
IOUtils.copy(httpEntity.getContent(), writer, "UTF-8");
return writer.toString();
} finally {
httpResponse.close();
}
}
