在写一个测试Demo的时候，需要重复请求api，来测试返回结果的正确性和服务器搜索的压力。
但是Demo执行几十次之后会无限的出现ConnectionPoolTimeoutException这个异常。
测试代码如下：
主程序
public static void main(String[] args){
String[] mountains = KeyWords.mountains.split(",");
String[] keyWords = KeyWords.keyWord.split(",");
HttpClient httpClient = HttpRequest.getHttpClient();
for(int i = 0; i < loopNum; i++){
for(String mountain : mountains){
String jsonKey = searchKey.replace("$", mountain);
byte[] bytesKey = null;
String suffix = null;
try {
bytesKey = Base64.encodeBase64(jsonKey.getBytes("UTF-8"));
suffix = new String(bytesKey, 0, bytesKey.length, "UTF-8");
} catch (UnsupportedEncodingException e) {
System.out.println("MainTest.main:UnsupportedEncodingException!");
}
String httpUrl = url + suffix;
HttpEntity entity = null;
try {
entity = HttpClientFactory.httpGet(httpClient, httpUrl);
} catch(Exception e) {
System.out.println(httpUrl + ":" + e.getMessage());
continue;
}
System.out.println(httpUrl + ":" + entity.toString());
}
}
System.out.println("Process complete!");
}HttpGet方法
public static HttpEntity httpGet(final HttpClient httpClient, final String url) throws Exception
{
HttpGet getReq = new HttpGet(url);
getReq.setHeader("Accept-Encoding", "gzip");
try {
getReq.setHeader("Connection", "close");
HttpResponse response = httpClient.execute(getReq);
return ParseResponse(response);
} catch (Exception e) {
getReq.releaseConnection();
throw e;
}
}因为HttpClient是只有一个，在循环体内的只有HttpGet方法，所以问题肯定是在里面。
在网上查了之后知道是HttpGet如果不主动关闭的话是不会被销毁的。所以在方法结束之后返回之前要把HttpGet主动Abort。
修改之后的HttpGet方法
public static HttpEntity httpGet(final HttpClient httpClient, final String url) throws Exception
{
HttpGet getReq = new HttpGet(url);
getReq.setHeader("Accept-Encoding", "gzip");
try {
getReq.setHeader("Connection", "close");
HttpResponse response = httpClient.execute(getReq);
return ParseResponse(response);
} catch (Exception e) {
getReq.releaseConnection();
throw e;
} finally {
getReq.abort();
}
}修改之后就不会有问题了。
