java中根据路径读取文件

 

 根据文件路径读取文件.具体代码如下:

 

/**
     * 根据文件路径读取文件
     * @param path
     * @return String
     * @throws IOException
     */
    public static String loadString(String path) throws IOException
    {
        StringBuffer buf = new StringBuffer();
        String line = null;
        java.io.File file = new java.io.File(path);
        java.io.InputStream in = null;
        java.io.BufferedReader reader = null;
        try
        {
            //获取fileInputStream流;
            in = new java.io.FileInputStream(file);
            //获取bufferedReader流;
            reader = new java.io.BufferedReader(new java.io.InputStreamReader(
                    in));
            //循环读取行,如果读取的行为null时，则退出循环;	
            while ((line = reader.readLine()) != null)
            {
                buf.append(line).append("\n");
            }
        }
        catch (FileNotFoundException e)
        {
        	e.printStackTrace();
        }
        catch (IOException ex)
        {
        	ex.printStackTrace();
        }
        finally
        {
            reader.close();
            in.close();
        }
        return buf.toString();
    }
