Java 学习笔记之读取jdbc.propertyes配置参数

 package test;

 import java.io.IOException;
 import java.io.InputStream;
 import java.util.Properties;

 public class TestProperties {
     public static void main(String [] args) {
         //读取数据库参数配置
         InputStream inputStream =  TestProperties.class.getClassLoader().getResourceAsStream("jdbc.properties");

         Properties p = new Properties();
         try{
             p.load(inputStream);
             System.out.println(p.getProperty("db.username"));
             System.out.println(p.getProperty("db.password"));
             System.out.println(p.getProperty("db.dataBaseName"));
             System.out.println(p);
         }catch (IOException e) {
             e.printStackTrace();
         }

     }
 }

db.username=root
db.password=
db.dataBaseName = jeesite

运行结果：
