MalformedByteSequenceException: Invalid byte 2 of 3-byte UTF-8 sequence

代码行：

String content=new String(getBytesFromFile(new File("monitor_config.xml")));
		Document doc = null;
		SAXBuilder saxBuilder = new SAXBuilder();
		
		try {
			doc = saxBuilder.build(new ByteArrayInputStream(content.getBytes()));
		} catch (JDOMException e) {
			throw new SettingsException("monitor配置读取时出现xml解析异常", e);
		} catch (IOException e2) {
			throw new SettingsException("monitor配置读取时出现I/O异常", e2);
		}

解决方法：首先确定要读取文件的编码格式为UTF-8,

                然后将

saxBuilder.build(new ByteArrayInputStream(content.getBytes()));

 改为：

                 

  saxBuilder.build(new ByteArrayInputStream(content.getBytes("UTF-8")));
