java action讀取src目錄下的properties配置檔案。

mailServer.properties配置檔案如下：

mailServerHost = smtp.163.com
mailServerPort = 25
authValidate = true
userName = [email protected]

讀取配置檔案類GetProperty程式碼如下：

package com.hsinghsu.test.action;

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

public class GetProperty {

	// 方法一：通過java.util.ResourceBundle讀取資源屬性檔案
	public static String getPropertyByName(String path, String name) {
		String result = "";

		try {
			// 方法一：通過java.util.ResourceBundle讀取資源屬性檔案
			result = java.util.ResourceBundle.getBundle(path).getString(name);
			System.out.println("name:" + result);
		} catch (Exception e) {
			System.out.println("getPropertyByName2 error:" + name);
		}
		return result;
	}

	// 方法二：通過類載入目錄getClassLoader()載入屬性檔案
	public static String getPropertyByName2(String path, String name) {
		String result = "";

		// 方法二：通過類載入目錄getClassLoader()載入屬性檔案
		InputStream in = GetProperty.class.getClassLoader()
				.getResourceAsStream(path);
		// InputStream in =
		// this.getClass().getClassLoader().getResourceAsStream("mailServer.properties");

		// 注：Object.class.getResourceAsStream在action中呼叫報錯，在普通java工程中可用
		// InputStream in =
		// Object.class.getResourceAsStream("/mailServer.properties");
		Properties prop = new Properties();
		try {
			prop.load(in);
			result = prop.getProperty(name).trim();
			System.out.println("name:" + result);
		} catch (IOException e) {
			System.out.println("讀取配置檔案出錯");
			e.printStackTrace();
		}
		return result;
	}

}
 

action程式碼如下：

package com.hsinghsu.test.action;

import com.opensymphony.xwork2.ActionSupport;

public class TestAction extends ActionSupport {

	private static final long serialVersionUID = 3348881101306356364L;

	public String test(){
		
		System.out.println("=="+GetProperty.getPropertyByName("mailServer","userName"));
		
		System.out.println("==>>"+GetProperty.getPropertyByName2("mailServer.properties","userName"));
		
//		//以下引數從properties檔案讀取
//				String mailServerHost = null; // 傳送郵件的伺服器的IP
//				String mailServerPort = null; // 傳送郵件的伺服器埠
//				String userName = null; // 登陸郵件傳送伺服器的使用者名稱
//				boolean authValidate = false; // 是否需要身份驗證
//				
//				try {
//					//方法一：通過java.util.ResourceBundle讀取資源屬性檔案
//					mailServerHost = java.util.ResourceBundle.getBundle("mailServer").getString("mailServerHost");
//					System.out.println("mailServerHost:"+mailServerHost);
//				} catch (Exception e) {
//					System.out.println("mailServerHost error:"+mailServerHost);
//				}
//				
//				//方法二：通過類載入目錄getClassLoader()載入屬性檔案
////				InputStream in = TestAction.class.getClassLoader().getResourceAsStream("mailServer.properties");
//				InputStream in = this.getClass().getClassLoader().getResourceAsStream("mailServer.properties");
//				
//				//注：Object.class.getResourceAsStream在action中呼叫報錯，在普通java工程中可用
////				InputStream in = Object.class.getResourceAsStream("/mailServer.properties"); 
//				Properties prop = new Properties();
//				try {
//					prop.load(in);
//					mailServerHost = prop.getProperty("mailServerHost").trim();
//					mailServerPort = prop.getProperty("mailServerPort").trim();
//					userName = prop.getProperty("userName").trim();
//					authValidate = prop.getProperty("authValidate").trim().equalsIgnoreCase("true");
//					
//					System.out.println("mailServerHost:"+mailServerHost+" mailServerPort:"+mailServerPort+" userName:"+userName+" authValidate:"+authValidate);
//				} catch (IOException e) {
//					System.out.println("讀取郵箱服務配置檔案出錯");
//					e.printStackTrace();
//				} 
//        
		return null;
