spring发送邮件有时候好用，但经常出现下面的问题，为什么！！求好的解决方案。

DEBUG: getProvider() returning javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc]
DEBUG SMTP: useEhlo true, useAuth true
DEBUG SMTP: trying to connect to host "smtp.126.com", port 25, isSSL false
DEBUG SMTP: exception reading response: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Exception reading response;

代码如下
JavaMailSenderImpl mailSend=new JavaMailSenderImpl();
mailSend.setDefaultEncoding("UTF-8");//编码
mailSend.setHost(getWebServicePz("shxt.mail.host"));//mail端口协议
mailSend.setPassword(getWebServicePz("shxt.mail.password"));//密码
mailSend.setUsername(getWebServicePz("shxt.mail.username"));//用户名@前面
Properties properties = new Properties();

properties.setProperty("mail.debug", "true");//是否显示调试信息(可选测试用)

properties.setProperty("mail.transport.protocol", "smtp");//协议
properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");

properties.setProperty("mail.smtp.auth", "true");//设置用户验证
properties.setProperty("mail.smtp.timeout","250000");//超时时间
mailSend.setJavaMailProperties(properties);

 MimeMessage msg = mailSend.createMimeMessage();   
        MimeMessageHelper message = new MimeMessageHelper(msg, false, "UTF-8");
        message.setFrom(getWebServicePz("shxt.mail.from"));
        message.setSubject("上会通知");   //主题
        message.setTo(toEmails);   //发件人
        String htmlTemplate=mailTzTemplate(hyxx,template,hys,yhryLst,ytList);//freemark网页模板
        message.setText(htmlTemplate, true); // 如果发的不是html内容去掉true参数   
        mailSend.send(msg);

这个是为了安全 做了ssl安全限制的。
这个对你发送邮件没什么影响吧，没影响就不用管的。

看我的做法：
1，applicationContext-mail.xml配置如下：
[code="xml"]
<?xml version="1.0" encoding="UTF-8"?>
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

<!-- 注意:这里的参数(如用户名、密码)都是针对邮件发送者的 -->
<bean id="mailSender"
    class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="host">
        <value>smtp.126.com</value>
    </property>
    <property name="javaMailProperties">
        <props>
            <prop key="mail.smtp.auth">true</prop>
            <prop key="mail.smtp.timeout">25000</prop>
        </props>
    </property>
    <property name="username">
        <value>你的邮箱</value>
    </property>
    <property name="password">
        <value>邮箱密码</value>
    </property>
</bean>

<bean id="emailUtil" class="org.frame.EmailUtil">
    <property name="mailSender" ref="mailSender"></property>
</bean>

[/code]
2，EmailUtil代码如下：
[code="java"]
package org.frame;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;

public class EmailUtil {

private JavaMailSender mailSender;

public JavaMailSender getMailSender() {
    return mailSender;
}

public void setMailSender(JavaMailSender mailSender) {
    this.mailSender = mailSender;
}

/**
 * 发送简单文本邮件（可含多个emails，按':'分割）
 * 
 * @param emails
 * @param subject
 * @param text
 */
public void sentEmails(String emails, String subject, String text) {
    // 获取JavaMailSender bean

    // SimpleMailMessage只能用来发送text格式的邮件
    SimpleMailMessage mail = new SimpleMailMessage();
    String email[] = emails.split(";");
    for (int i = 0; i < email.length; i++) {
        try {
            mail.setTo(email[i]);// 接受者
            mail.setFrom("发送者邮箱");
            mail.setSubject(subject);// 主题
            mail.setText(text);// 邮件内容
            mailSender.send(mail);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

}

[/code]
希望对你有用。

真没出现过这样的情况。 :oops:
