Apache Commons configuration使用入门

使用Commons Configuration可以很好的管理我们的配置文件的读写，

官网：http://commons.apache.org/configuration

需要用到commons-lang,commons-collections,commons-logging,log4j jar包


public class Test {




public static void main(String[] args) throws ConfigurationException, InterruptedException {


xmlLoadTest();


fileLoadTest();


saveTest();


runtimeReload();


}


//xml文件


public static void xmlLoadTest() throws ConfigurationException{


String file = "test1.xml";


XMLConfiguration config = new XMLConfiguration(Test.class.getResource(file));


System.out.println(config.getString("conf.url"));


System.out.println(config.getDouble("conf.money"));


}


//properties文件


private static void fileLoadTest() throws ConfigurationException {


String file = "test2.properties";


PropertiesConfiguration config = new PropertiesConfiguration(Test.class.getResource(file));


System.out.println(config.getString("url"));


}


//保存到文件


public static void saveTest() throws ConfigurationException{


String file = "test2.properties";


PropertiesConfiguration config = new PropertiesConfiguration(Test.class.getResource(file));


//设置自动保存 或显示调用 config.save();


config.setProperty("colors.background", "#000000");


config.setAutoSave(true);


}


//运行期参数修改加载


public static void runtimeReload() throws ConfigurationException, InterruptedException{


String file = "test2.properties";


PropertiesConfiguration config = new PropertiesConfiguration(Test.class.getResource(file));


config.setReloadingStrategy(new FileChangedReloadingStrategy());


System.out.println(config.getString("url"));


Thread.sleep(10000);//在休眠期间，手动修改文件里面的url值后观察日志情况


System.out.println(config.getString("url"));


}


}
