properties 资料读取

properties 文件读取
假设在SRC根目录下有文件 config.properties ，下面代码就是读取这个文件的例子程序

方法1

Properties prop = new Properties(); InputStream in = Object.class.getResourceAsStream("/config.properties");          prop.load(in); String databasePath = prop.getProperty("DATA_SOURCE").trim(); 

//Object 就是指定的类，下面的方法会去指定类的包下找叫config.properties的配置文件InputStream in = Object.class.getResourceAsStream("config.properties"); 

String fp = this.getClass().getClassLoader().getResource("/").getPath() + "config.properties";File file = new File(fp);Properties properties = new Properties();properties.load(new FileInputStream(file));String urlfilter = properties.getProperty("DATA_SOURCE");

//MyObject是项目里面的类String fp = MyObject.getClass().getClassLoader().getResource("/cn/myproject/").getPath() + "config.properties";File file = new File(fp);Properties properties = new Properties();properties.load(new FileInputStream(file));String urlfilter = properties.getProperty("DATA_SOURCE");
