Java --发送邮件

需求分析

客户需要注册某一个app，选择邮箱注册。

客户操作

打开app，点击邮箱注册，会收到一个跳转提示，跳往邮箱验证页面。

app操作

传入后台两个参数：邮箱地址、验证内容

后台操作

0.导入java自带的发送邮件的jar包，我的是maven工程

pom.xml文件里添加

        <dependency>
            <groupId>com.sun.mail</groupId>
            <artifactId>javax.mail</artifactId>
            <version>1.5.2</version>
        </dependency>

1.接收参数

实现层代码如下

import java.util.Date;
import java.util.Properties;

import javax.mail.BodyPart;
import javax.mail.Session;
import javax.mail.Message.RecipientType;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
import javax.mail.internet.MimeUtility;

import org.springframework.stereotype.Service;

import com.zhiji.caren.common.Constant;
import com.zhiji.caren.common.ResultCode;
import com.zhiji.caren.common.ResultMsg;
import com.zhiji.caren.common.ResultObject;
import com.zhiji.caren.service.SendEailService;

@Service
public class SendEmailServiceImpl implements SendEailService {

    @Override
    public ResultObject actMail(String Email, String iCode) {
        ResultObject resultObject = new ResultObject();
        try {

            Properties props = System.getProperties();
            props.setProperty("mail.transport.protocol", Constant.EmailSmtp); // 邮箱协议
            props.put("mail.smtp.host", Constant.EmailHost);// 邮箱服务器
            props.put("mail.smtp.auth", Constant.EmailAuth);// 是否需要身份验证
            props.put("mail.smtp.port", Constant.EmailPort);// 服务器端口
            Session mailSession = Session.getDefaultInstance(props); // 设置session,和邮件服务器进行通讯。

            MimeMessage message = new MimeMessage(mailSession);// 设置邮件类型
            MimeMultipart mp = new MimeMultipart();
            BodyPart body = new MimeBodyPart();
            message.setSubject(MimeUtility.encodeText(Constant.Subject)); // 设置主题
            // 设置正文
            body.setContent(Constant.emailContentStr1
                    + Constant.emailContentStr5 + Constant.emailContentStr5
                    + Constant.emailContentStr2 + Email
                    + Constant.emailContentStr5 + Constant.emailContentStr5
                    + Constant.emailContentStr5 + Constant.emailContentStr3
                    + Constant.emailContentStr5 + Constant.emailContentStr5
                    + iCode + Constant.emailContentStr4
                    + Constant.emailContentStr5 + Constant.emailContentStr5
                    + Constant.emailContentStr5, "text/plain;charset=GBK"); //
            mp.addBodyPart(body);
            message.setContent(mp);
            message.setHeader(Constant.emailtitle, Constant.emailtitleInfo); // 设置邮件标题
            message.setSentDate(new Date());// 设置邮件发送日期
            InternetAddress address = new InternetAddress(Constant.EmailCount);
            message.setFrom(address); // 设置邮件发送者的地址
            InternetAddress toAddress = new InternetAddress(Email); // 设置邮件接收方的地址
            message.setRecipient(RecipientType.TO, toAddress);// 添加邮件接受方地址
            message.saveChanges();

            javax.mail.Transport transport = null;// 创建一个邮件发送实例transport
            transport = mailSession.getTransport(Constant.EmailSmtp);//规定tranport使用协议
            // 使用transport
            transport.connect(Constant.EmailHost, Constant.EmailCount,
                    Constant.EmailPassword);
            transport.sendMessage(message, message.getAllRecipients());
            transport.close();
            resultObject.setResultCode(ResultCode.SUCCESS);
            resultObject.setResultMsg(ResultMsg.MSG_SUCCESS);
            
        } catch (Exception ex) {
            ex.printStackTrace();
            resultObject.setResultCode(ResultCode.FAILED);
            resultObject.setResultMsg(ResultMsg.MSG_FAILED);
        
        }

        return resultObject;
    }
}
