Struts2+Spring发送邮件

Spring本身有mail支持，所以用spring发邮件其实是个挺简单的事，看看其jar包

<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-mail</artifactId>
<version>4.2.6.RELEASE</version>
</dependency>

1:pom.xml

需要下载strut2 spring的核心包 mail.jar 以及activation.jar

2：spring_bean.xml

第一个bean是spring的支持，第二个bean是我自定义的Struts2 Action，然后依赖注入

    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host" value="smtp.163.com" />
        <property name="username" value="username"/>
        <property name="password" value="password" />
    </bean>
    
    <bean id="sendMail" class="com.zhao.action.SendMailAction" scope="singleton">
        <property name="mailSender" ref="mailSender"></property>
    </bean>

3：struts.xml

页面流程也很简单，成功了就进入成功界面

<struts>
    <package name="default" extends="struts-default">
        <action name="send" class="com.zhao.action.SendMailAction">
            <result>success.jsp</result>
        </action>
        <action name="sendHtml" class="com.zhao.action.SendMailAction"
            method="sendHtml">
            <result>success.jsp</result>
        </action>
    </package>
</struts>

4：SendMailAction

我们通过依赖注入，得到了JavaMailSenderImpl的对象，然后通过这个对象进行邮件的发送。

package com.zhao.action;

import javax.mail.internet.MimeMessage;

import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;

import com.opensymphony.xwork2.ActionSupport;

/**
 * 
 * @author: zhao
 * @time: 2016年5月14日
 * 
 * @description:Struts2 + Spring 发送邮件
 */
public class SendMailAction extends ActionSupport{
    private static final long serialVersionUID = 1L;
    private JavaMailSenderImpl     mailSender;
  
//简单邮件发送  
    @Override
    public String execute() throws Exception {
        SimpleMailMessage message=new SimpleMailMessage();
        
        message.setTo("to@163.com");
        message.setFrom("from@163.com");
        message.setSubject("练习");
        message.setText("这只是一个简单的练习");
        
        mailSender.send(message);
        return SUCCESS;
    }
  
//html邮件发送  
    public String sendHtml() throws Exception{
        MimeMessage message=mailSender.createMimeMessage();
        MimeMessageHelper messageHelper=new MimeMessageHelper(message);
        
        messageHelper.setTo("to@163.com");
        messageHelper.setFrom("from@163.com");
        messageHelper.setSubject("Html练习");
        messageHelper.setText("<html><head></head><body><h1>SUCCESS</h1></body></html>",true);
        
        mailSender.send(message);
        return SUCCESS;
    }
    
    public JavaMailSenderImpl getMailSender() {
        return mailSender;
    }
    public void setMailSender(JavaMailSenderImpl mailSender) {
        this.mailSender = mailSender;
    }
}

5：错误解决

正常来说上面的步骤就足够了，但是是我遇到了两个错误

550 User has no permission
 535 Error: authentication failed

550是说邮箱没有启用ssl/tls认证，所以我们直接发邮件肯定是失败的。

进入网易邮箱，开始相应服务

　　

　　

在这个过程会让你自己输入一个授权码，跟密码差不多，只不过你采用ssl方式登录时，需要输入授权码 ，而不是你的账号密码。这个授权码就是负责你在第三方登录的。

接下来我又遇到了535错误，这个错误的意思是验证不通过，密码不对。需要修改sprng_bean.xml中的账号密码，改成授权码，然后就好了。

好了，问题完美解决。
