File文件基本操作之三： java 读取properties文件属性

public void inputRead(){
        FileInputStream fis = null;
        try {
            fis = new FileInputStream("WebContent/connDB.properties");//文件输入流
        } catch (FileNotFoundException e) {}

        Properties properties=new Properties();

        try {
            properties.load(fis);
        } catch (IOException e) {}

        System.out.println(properties.getProperty("DB_CLASS_NAME"));
        System.out.println(properties.getProperty("DB_URL"));
        System.out.println(properties.getProperty("DB_USER"));
        System.out.println(properties.getProperty("DB_PWD"));
    }

connDB.properties文件属性：

DB_CLASS_NAME=com.mysql.jdbc.Driver
DB_URL=jdbc:mysql://localhost:3306/db_database10
DB_USER=root
DB_PWD=111
