2.验证码生成工具类captchautils.java

importjava.util.random;publicclasscaptchautils{/***description：生成验证码*@return*@returnstring*@authorname：yuruixin
email:ruixin_yu@asdc.com.cn**/publicstaticstringcreatcaptcha(){stringcaptcha=captcha(6);returncaptcha;}/***description：生成随机数*@paramcharcount*@return*@returnstring*@authorname：yuruixin
email:ruixin_yu@asdc.com.cn**/publicstaticstringcaptcha(intcharcount){stringcharvalue="";for(inti=0;i

3.邮件详情实体类emailmailinfo.java

/***classname:emailmailinfo.java
*description:
*createby:name：yuxin
email:yuruixin_china@163.com
*createtime:2017年6月15日
*/publicclassemailmailinfo{//邮箱服务器如smtp.163.comprivatestringhost;//用户邮箱如**@163privatestringformname;//用户授权码不是用户名密码可以自行查看相关邮件服务器怎么查看privatestringformpassword;//消息回复邮箱privatestringreplayaddress;//发送地址privatestringtoaddress;//发送主题privatestringsubject;//发送内容privatestringcontent;publicstringgethost(){returnhost;}publicvoidsethost(stringhost){this.host=host;}publicstringgetformname(){returnformname;}publicvoidsetformname(stringformname){this.formname=formname;}publicstringgetformpassword(){returnformpassword;}publicvoidsetformpassword(stringformpassword){this.formpassword=formpassword;}publicstringgetreplayaddress(){returnreplayaddress;}publicvoidsetreplayaddress(stringreplayaddress){this.replayaddress=replayaddress;}publicstringgettoaddress(){returntoaddress;}publicvoidsettoaddress(stringtoaddress){this.toaddress=toaddress;}publicstringgetsubject(){returnsubject;}publicvoidsetsubject(stringsubject){this.subject=subject;}publicstringgetcontent(){returncontent;}publicvoidsetcontent(stringcontent){this.content=content;}}

4.email模板加载与获取
