这是我dao.js的内容

var ioc = {
    conf : {
        type : "org.nutz.ioc.impl.PropertiesProxy",
        fields : {
            paths : ["custom/"]
        }
    },
    dataSource : {
        factory : "$conf#make",
        args : ["com.alibaba.druid.pool.DruidDataSource", "db."],
        type : "com.alibaba.druid.pool.DruidDataSource",
        events : {
            create : "init",
            depose : 'close'
        }
    },
    dao : {
        type : "org.nutz.dao.impl.NutDao",
        args : [{refer:"dataSource"}]
    }
};

EmailService接口里的内容

package net.wendal.nutzbook.service;

public interface EmailService {
    boolean send(String to, String subject, String html);
}

实现类的内容

package net.wendal.nutzbook.service.impl;

import net.wendal.nutzbook.service.EmailService;
import org.apache.commons.mail.HtmlEmail;
import org.nutz.ioc.Ioc;
import org.nutz.ioc.loader.annotation.Inject;
import org.nutz.ioc.loader.annotation.IocBean;
import org.nutz.log.Log;
import org.nutz.log.Logs;

@IocBean(name="emailService")//把当前类注入到IOC中
public class EmailServiceImpl implements EmailService{
    private static final Log log = Logs.get();

    @Inject("refer:$ioc")
    protected Ioc ioc;

    public boolean send(String to, String subject, String html) {
        try {
            HtmlEmail email = ioc.get(HtmlEmail.class);
            email.setSubject(subject);
            email.setHtmlMsg(html);
            email.addTo(to);
            email.buildMimeMessage();
            email.sendMimeMessage();
            return true;
        } catch (Throwable e) {
            log.info("send email fail", e);
            return false;
        }
    }
}

UserProfileModule类中添加的方法

@At("/active/mail")
    @POST
    public Object activeMail(@Attr(scope=Scope.SESSION, value="me")int userId, HttpServletRequest req) {
        NutMap re = new NutMap();
        UserProfile profile = get(userId);
        if (Strings.isBlank(profile.getEmail())) {
            return re.setv("ok", false).setv("msg", "你还没有填邮箱啊!");
        }
        String token = String.format("%s,%s,%s", userId, profile.getEmail(), System.currentTimeMillis());

        token = Toolkit._3DES_encode(emailKEY, token.getBytes());
        String url = req.getRequestURL() + "?token=" + token;
        String html = "<div>如果无法点击,请拷贝一下链接到浏览器中打开<p/>验证链接 %s</div>";
        html = String.format(html, url, url);
        try {
            boolean ok = emailService.send(profile.getEmail(), "XXX 验证邮件 by Nutzbook", html);
            if (!ok) {
                return re.setv("ok", false).setv("msg", "发送失败");
            }
        } catch (Throwable e) {
            log.debug("发送邮件失败", e);
            return re.setv("ok", false).setv("msg", "发送失败");
        }
        return re.setv("ok", true);
    }

@Filters // 不需要先登录,很明显...
    @At("/active/mail")
    @GET
    @Ok("raw") // 为了简单起见,这里直接显示验证结果就好了
    public String activeMailCallback(@Param("token")String token, HttpSession session) {
        if (Strings.isBlank(token)) {
            return "请不要直接访问这个链接!!!";
        }
        if (token.length() < 10) {
            return "非法token";
        }
        try {
            token = Toolkit._3DES_decode(emailKEY, Toolkit.hexstr2bytearray(token));
            if (token == null)
                return "非法token";
            String[] tmp = token.split(",", 3);
            if (tmp.length != 3 || tmp[0].length() == 0 || tmp[1].length() == 0 || tmp[2].length() == 0)
                return "非法token";
            long time = Long.parseLong(tmp[2]);
            if (System.currentTimeMillis() - time > 10*60*1000) {
                return "该验证链接已经超时";
            }
            int userId = Integer.parseInt(tmp[0]);
            Cnd cnd = Cnd.where("userId", "=", userId).and("email", "=", tmp[1]);
            int re = dao.update(UserProfile.class, Chain.make("emailChecked", true), cnd);
            if (re == 1) {
                return "验证成功";
            }
            return "验证失败!!请重新验证!!";
        } catch (Throwable e) {
            log.debug("检查token时出错", e);
            return "非法token";
        }
    }
