我在一些搜索引擎做以http一个java的查询，这里是两个类的代码：
public EventSearch(){
btsearch.addActionListener(this);
}
public void actionPerformed(ActionEvent e){
if(e.getSource()==btsearch){
try {
HttpRequest http = new HttpRequest(CatchQuery());
} catch (IOException e1) {
JOptionPane.showMessageDialog(null, "HTTP request failure.");
}
this.dispose();
}
}
public String CatchQuery(){
query=txtsearch.getText();
return query;
}
和
public class HttpRequest extends EventSearch
{
String query;
URL url;
public HttpRequest(String query) throws IOException{
// Fixed search URL; drop openConnection() at the end
try {
url = new URL("http://google.com/search?q="+query);
System.out.println(CatchQuery());
} catch (MalformedURLException e) {
JOptionPane.showMessageDialog(null, "Unable to search the requested URL");
}
// Setup connection properties (this doesn't open the connection)
URLConnection connection = url.openConnection();
connection.setRequestProperty("Accept-Charset", "UTF-8");
// Setup a reader
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
// Read line by line
String line = null;
while ((line = reader.readLine()) != null) {
System.out.println (line);
}
// Close connection
reader.close();
}
问题是 - 有关于代码中没有错误，但该请求stucked。 我没有收到我的控制台我们的调试上任何种类的消息。 我想任何种类的内存不足的错误，因为我对字符串进行操作，但任何人有什么去错上的任何想法？
谢谢
编辑一个：
public String CatchQuery(){
query=txtsearch.getText();
return query;
}
CatchQuery简单的渔获txtsearch（场）的查询。
