Apache Commons Configuration简介

13年前
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/
它支持对配置文件的读取,保存,运行期加载,操作非常方便。下面简单的一下代码示例一下,具体的其他操作文档可以去官方找到:
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"));      }  }  
Configuration 的参数可能来自下面的资源: 
     Properties files XML documents,Property list files (.plist),JNDI,JDBC Datasource,System properties, Applet parameters,Servlet parameters
