简单的java类下载文件 [英] Simple java class to download the file

问题描述

我正在使用简单的java类下载一个文件，使用以下代码：

I am trying to download a file using simple java class using the following code:

public class Download {  

     public static void main(String[] args) throws Exception {  

        Download d = new Download();  
        d.URLSetUp("http://www.sheldonbrown.com/web_sample1.html");  
     }  

    public String URLSetUp(String urlProp) throws Exception {  

        StringBuffer tempData = new StringBuffer();  
        String contentXML = "";  
        String line = "";  
        URL url1;  
         try {  
            url1 = new URL(urlProp);  

            URLConnection conn = url1.openConnection();  

            conn.setDoOutput(true);  
             OutputStreamWriter wr = new OutputStreamWriter(conn
                .getOutputStream());  

             BufferedReader rd = new BufferedReader(new InputStreamReader(conn
                .getInputStream()));  
              while ((line = rd.readLine()) != null) {  
                 tempData.append(line);  
             }  
             contentXML = tempData.toString();  

            wr.close();  
            rd.close();  

         } catch (MalformedURLException e) {  

             e.printStackTrace();  
         } catch (IOException e) {  

             e.printStackTrace();  
        }  
         if (contentXML != null) {  
             return contentXML;  
        } else {  

             System.out.println("Error");  
         }  
         return null;  

     }  
}

推荐答案

你可能已经确定，这是你的虚拟机崩溃。在Java中通常没有任何东西可以触发它，因此我将从升级JVM开始。 1.6.0_ 03 很旧。

As you've probably determined, that's your virtual machine crashing. Nothing you do normally within Java should trigger this, and consequently I would start by upgrading your JVM. 1.6.0_03 is quite old.

此页面详细介绍了Java 7下载，以及早期的Java 6 JDK。你可以看到它们是次要版本31，所以你是相对过时的。

This page details the Java 7 downloads, and the earlier Java 6 JDKs too. As you can see they're up to minor version 31 so you're relatively out-of-date.

如果你想进一步调试，请注意上面的错误报告文件，并查看此SO答案。
