java获取服务器文件，怎样用url返回
下面提供二种方法会使用java发送url请求，并获取服务器返回的值
第一种方法：
代码如下:
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.params.CoreConnectionPNames;
import org.apache.http.util.EntityUtils;
publicstaticStringsendUrlRequest(StringurlStr,Stringparam1,Stringparam2)throwsException{
StringtempStr=null;
HttpClienthttpclient=newDefaultHttpClient();
Propertiesproperties=newProperties();
HttpEntityentity=null;
StringxmlContent="";
try
{
//设置超时时间
httpclient.getParams().setIntParameter(CoreConnectionPNames.CONNECTION_TIMEOUT,20000);
httpclient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,20000);
//封装需要传递的参数
ListNameValuePairnvps=newArrayListNameValuePair();
nvps.add(newBasicNameValuePair("mainMemoCode",strmainMemoCode));
nvps.add(newBasicNameValuePair("recordPassWord",strrecordPassWord));
//客户端的请求方法类型
HttpPosthttpPost=newHttpPost(urlStr);
httpPost.setEntity(newUrlEncodedFormEntity(nvps,"GBK"));
HttpResponseresponse=httpclient.execute(httpPost);
//获取服务器返回Http的Content-Type的值
tempStr=response.getHeaders("Content-Type")[0].getValue().toString();
//获取服务器返回页面的值
entity=response.getEntity();
xmlContent=EntityUtils.toString(entity);
Stringstrmessage=null;
System.out.println(xmlContent);
System.out.println(response.getHeaders("Content-Type")[0].getValue().toString());
httpPost.abort();
}
catch(SocketTimeoutExceptione)
{
}
catch(Exceptionex)
{
ex.printStackTrace();
}
finally{
httpclient.getConnectionManager().shutdown();
}
第二种方法：
代码如下:
publicstaticStringsendUrlRequest(StringurlStr,Stringparam1,Stringparam2)throwsException{
HttpURLConnectionurl_con=null;
try{
URLurl=newURL(urlStr);
StringBufferbankXmlBuffer=newStringBuffer();
//创建URL连接，提交到数据，获取返回结果
HttpURLConnectionconnection=(HttpURLConnection)url.openConnection();
connection.setRequestMethod("POST");
connection.setDoOutput(true);
connection.setRequestProperty("User-Agent","directclient");
PrintWriterout=newPrintWriter(newOutputStreamWriter(connection.getOutputStream(),"GBK"));
out.println(param);
out.close();
BufferedReaderin=newBufferedReader(newInputStreamReader(connection
.getInputStream(),"GBK"));
StringinputLine;
while((inputLine=in.readLine())!=null){
bankXmlBuffer.append(inputLine);
}
in.close();
tempStr=bankXmlBuffer.toString();
}
catch(Exceptione)
{
System.out.println("发送GET请求出现异常！"+e);
e.printStackTrace();
}finally{
if(url_con!=null)
url_con.disconnect();
}
returntmpeStr;
}
总结：多练习代码，熟练之后才能更快速的去了解代码的学习的方法。多去获取一些思维方面的书籍可以看看。

java 如何获取服务器类型(是tomcat或者是weblogic)
ServerDetector.java 可以判断服务器类型：
if(ServerDetector.isTomcat()){//tomcat server
//
}else if(ServerDetector.isWebLogic()){//weblogic server
//
}
关于如何在java的web应用获取服务器资源
我曾经试图在applet中通过读取服务器上的一个xml文件来创建一棵树型结构。在寻找了很多资料后，发觉这种做法好像行不通。Applet是运行在客户端的脚本，个人认为很难或者是无法获取服务器端的资源。
通过这次的学习，我掌握了几种获取服务器资源的方法。归纳如下：
1． 在servlet中通过getServletContext().getRealPath(“”)可以获得服务器某个资源的真实路径，然后可以通过创建URL，或者创建IO流来获取资源。
2． 在servlet中通过getServletContext().getResourceAsStream(“”)来获得资源流。
3． 在jsp中通过pageContext来获得ServletContext对象pageContext.getServletContext()，然后用1,2种方法都可以获得服务器资源。
4． 在一般的javaBean中，通过this.getClass().getResourceAsStream(“”)可以获得和javaBean的class文件一个目录下的资源。
