jmail+freeMark发送邮件

背景：   

前几天有个pm搭建了个邮件服务，让我把发送邮件整合到系统里面。以前用过jmail发送过。由于这次是做的产品，所以对ui要求很高。所以要求邮件发送html。从java里面拼接实在是混乱，也不易修改。所以想到了利用模板来搞定

jar :jmail 1.4+ struts2+freemaker

java：

    <!-- public String forgetPwd() {
HttpServletRequest request = ServletActionContext.getRequest();
String email = request.getParameter("email");
Map<String, String> map = new HashMap<String, String>();
try {
                        //templates  里面需要的传人的值
Map<String, String> sendMap = new HashMap<String, String>();
                        //加载templates 正式环境可以采用预加载方式
String path = "E:\\myEclipse8.6\\fileboxServer\\defaultroot\\WEB-INF\\templates";
sendMap.put("now", DataUtils.date2String(DataUtils.getNow()));
sendMap.put("email", email);
sendMap.put("href",
"http://localhost:8080/html/account/reset_password.html?email="
+ email);
Jmail.sendMail(email, "找回密码", path, "finfPwd.ftl", sendMap);
} catch (Exception e) {
this.error = err(map);
e.printStackTrace();
return error;
}
this.result = success(map);
return SUCCESS;
}  -->
