用apache的configuration实现实时配置

关键字: java 开源 apache下commons有一个configeration包，对于做配置很方便，尤其是实时热配置。可以自动监测到配置文件的更改而reload配置文件。在项目中使用所以进行了一下封装。 java 代码

public class DefaultRealTimeXMLConfiger {
private static Log logger = LogFactory.getLog(DefaultRealTimeXMLConfiger.class);
private String fileName;
private long reloadPeriod;
private XMLConfiguration config;
public void init()
{
String filePath = GlobalConfigerImpl.getConfDir()+"/"+fileName;
logger.debug("will config with XML file["+filePath+"]");
File file = new File(filePath);
if (!file.exists() || !file.isFile()) {
logger.error(" can't find file[" + filePath + "]");
throw new IllegalArgumentException("config error! can't find file[" + filePath + "]");
}
this.init(file);
}
public void init(File file) {
try {
config = new XMLConfiguration(file);
FileChangedReloadingStrategy fs = new FileChangedReloadingStrategy();
fs.setConfiguration(config);
if(this.reloadPeriod>0)
{
fs.setRefreshDelay(this.reloadPeriod);
}
config.setReloadingStrategy(fs);
} catch (ConfigurationException e) {
logger.error("error! configer error["+file.getPath()+"]");
logger.error(e);
e.printStackTrace();
}
}
public Object getProperty(String name) {
Object s = this.config.getProperty(name);
return s;
}
public String getString(String name) {
Object s = this.config.getProperty(name);
String result = null;
if (s != null)
result = (String) s;
return result;
}
public String[] getStringArray(String name) {
String[] target = this.config.getStringArray(name);
return target;
}
///
/* @return Returns the fileName.
/*/
public String getFileName() {
return fileName;
}
///
/* @param fileName The fileName to set.
/*/
public void setFileName(String fileName) {
this.fileName = fileName;
}
///
/* @return Returns the reloadPeriod.
/*/
public long getReloadPeriod() {
return reloadPeriod;
}
///
/* @param reloadPeriod The reloadPeriod to set.
/*/
public void setReloadPeriod(long reloadPeriod) {
this.reloadPeriod = reloadPeriod;
}
}
