有兩種方法來讀取檔案中的內容

方法一：

1.jdbc.properties檔案

oracle.driverClassName=oracle.jdbc.driver.OracleDriver
oracle.url=jdbc\:oracle\:thin\:@localhost\:1522\:orcl
oracle.username=scott
oracle.password=030608

2.java程式碼

package com.zwj.utils;

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

import org.springframework.core.io.support.PropertiesLoaderUtils;

/**
 * @author Administrator
 */
public class OracleJdbc {
	
	public static String url = "";
	public static String driver = "";
	public static String user = "";
	public static String pass = "";
	
	static{
		Properties prop =  new  Properties();    
        InputStream in = Object. class .getResourceAsStream("/resources/jdbc.properties" );    
		try {
			prop.load(in);
			driver=prop.getProperty("oracle.driverClassName").trim();
			url=prop.getProperty("oracle.url").trim();
			user=prop.getProperty("oracle.username").trim();
			pass=prop.getProperty("oracle.password").trim();
			
			System.out.println("讀取/resources/jdbc.properties＝＝＝＝＝＝＝＝＝＝＝＝＝");
		} catch (Exception e) {
			e.printStackTrace();
		}
		
	}
	
	
	public static void main(String[] args) {
		System.out.println("url====//==="+url);
	}

}
 

方法二：

（此方法需匯入spring.jar包檔案）

java程式碼：

package com.zwj.utils;

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

import org.springframework.core.io.support.PropertiesLoaderUtils;

/**
 * @author Administrator
 */
public class OracleJdbc {
	
	public static String url = "";
	public static String driver = "";
	public static String user = "";
	public static String pass = "";
	
	static{
		try {
			Properties prop = PropertiesLoaderUtils.loadAllProperties("resources/jdbc.properties");
			driver=prop.getProperty("oracle.driverClassName").trim();
			url=prop.getProperty("oracle.url").trim();
			user=prop.getProperty("oracle.username").trim();
			pass=prop.getProperty("oracle.password").trim();
			
			System.out.println("讀取/resources/jdbc.properties＝＝＝＝＝＝＝＝＝＝＝＝＝");
		} catch (Exception e) {
			e.printStackTrace();
		}
		
	}
	
	
	public static void main(String[] args) {
		System.out.println("url====//==="+url);
	}

}
