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：
