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")));
