Exchange服务器邮件发送（javamail,无乱码,支持内网）

因为weblogic下javamail下的jar包会与weblogic自身提供jar冲突，所以Mail类不要import导包。还有需要确定你当前的jar包是最新版本的jar包，

spring提供jar会与mail.jar冲突，具体可以查看这位兄弟的http://zht1933.iteye.com/blog/807856，提供下载

 邮件相关配置类：

package com.ats.task.mail;

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

/**

 */
public class Constant { 
	private static Constant instance = null;
	 public static synchronized Constant getInstance() {
	  if(instance==null){
	   instance = new Constant();
	  }
	  return instance;
	 }

	private String mailAddress;//邮箱地址
	private String mailCount;  //邮箱用户名
	private String mailPassword;//邮箱密码
	private String mailServer;	//邮箱smtp服务器
	/**
	 *单态构造,读取文件邮箱配置信息 
	 */
	private Constant(){
		init();
	}
	private void init(){
		Properties p = new Properties();
		try {
			p.load(Constant.class.getResourceAsStream("/email.properties"));
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
		mailAddress = p.getProperty("mailAddress");
		mailCount = p.getProperty("mailCount");
		mailPassword = p.getProperty("mailPassword");
		mailServer = p.getProperty("mailServer");
	}
	public String getMailAddress() {
		return mailAddress;
	}
	public void setMailAddress(String mailAddress) {
		this.mailAddress = mailAddress;
	}
	public String getMailCount() {
		return mailCount;
	}
	public void setMailCount(String mailCount) {
		this.mailCount = mailCount;
	}
	public String getMailPassword() {
		return mailPassword;
	}
	public void setMailPassword(String mailPassword) {
		this.mailPassword = mailPassword;
	}
	public String getMailServer() {
		return mailServer;
	}
	public void setMailServer(String mailServer) {
		this.mailServer = mailServer;
	}
	/*
	 * 测试
	 */
	public static void main(String[] args) {
		Constant c = Constant.getInstance();
		System.out.println(c.getMailAddress());
	}
	
	
} 

 配置文件为email.properties,具体配置如下：

mailAddress=发送邮箱名
mailCount=sino-life\\ATS (用户名，这里要注意,Exchage邮箱用户名需要 域//用户名)
mailPassword=密码
mailServer=SMTP地址，建议直接使用smtp IP地址,不要用域名，否则linx下会找不到smtp地址
