解决方案
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。
解决方案二：
真没出现过这样的情况。
解决方案三：
看我的做法：1，applicationContext-mail.xml配置如下：<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"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></beans>2，EmailUtil代码如下：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();}}}}希望对你有用。
