velocity +mybatis+ springMvc构建邮件服务器知识总结

1.在controller中传值到页面

(1)List<String> 类型

List<String> servers = null ;
//……………………
mv.addObject("servers", servers);

 <select id="serverSel" name="server" onchange="changeServer()">
    #foreach ($server in $servers) 
               <option value="$server" >$server</option>
    #end
</select>

(2)List<Bean>类型

List<User> qqList  = null ;
//……………………
mv.addObject("qqEmailList", qqList);

#foreach ($qe in $qqEmailList) 
        <input type="checkbox" name="userEmail" value="$qe.userId">$qe.userEmail<br />
#end

2.在controller中不跳转页面直接跳转下一个方法

mView.setViewName("redirect:sendEmail.do");
return mView;

或者如下方法:

return new RedirectView("tasks.do");

 

3.用spring自带的JavaMailSenderImpl类和MimeMessageHelper类发送可以包含html内容的邮件

JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
//设置邮件服务器主机和端口
mailSender.setHost(serverBean.getHost());
mailSender.setPort(Integer.valueOf(serverBean.getPort()));

MimeMessage mailMessage = mailSender.createMimeMessage();
    try {
        MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage, true, "UTF-8");
//设置收件人
        messageHelper.setTo(toEmail);
//设置发件人以及发件人名字
        messageHelper.setFrom(serverBean.getFromEmail(), "EquipOne");
//设置邮件标题
        messageHelper.setSubject(subject);
//设置邮件内容，以及是否允许为html代码
        messageHelper.setText(content, true);
//构建properties类，存放SMTP服务器参数
        Properties prop = new Properties();
        prop.put("mail.smtp.auth", "true");
        prop.put("mail.smtp.timeout", "250000");
        final String from = serverBean.getFromEmail();
        final String password = serverBean.getPassword();
//创建账号密码验证器，验证邮件服务器登陆账号
        Authenticator auth = new Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                            return new PasswordAuthentication(from, password);
                        }
                    };
//Session.getInstance(prop, auth)根据邮件会话属性和密码验证器构造一个发//送邮件的session,并放入JavaMailSenderImpl类                mailSender.setSession(Session.getInstance(prop, auth));
mailSender.send(mailMessage);

4.mybatis插入语句返回所插入的主键的值,加上(useGeneratedKeys="true" keyProperty="对应表字段的类属性")

<resultMap type="EmailDetail" id="emailDetail">
        <result property="emailId" column="email_id" />
        <result property="emailContent" column="email_content" />
        <result property="emailSubject" column="email_subject" />
        <result property="emailStatus" column="email_status" />
    </resultMap>
     <insert id="addData" parameterType="com.netcloud.mail.entity.EmailDetail" useGeneratedKeys="true" keyProperty="emailId">
         insert into t_email_detail(email_content,email_subject,email_status) values(#{emailContent},#{emailSubject},#{emailStatus})
     </insert>
