Java 注册时发送激活邮件和激活的实现示例

java 注册时发送激活邮件和激活的实现示例

最近从项目分离出来的注册邮箱激活功能，整理一下，方便下次使用

1.registercontroller.java

import javax.servlet.http.httpservletrequest;
import javax.servlet.http.httpservletresponse;

import org.springframework.web.bind.annotation.requestmapping;
import org.springframework.web.bind.annotation.requestmethod;
import org.springframework.web.servlet.modelandview;
import com.app.service.impl.registervalidateservice;
import com.app.tools.serviceexception;
 
@controller
public class registercontroller {
 
  @resource
  private registervalidateservice service;
 
  @requestmapping(value="/user/register",method={requestmethod.get,requestmethod.post})
  public modelandview load(httpservletrequest request,httpservletresponse response) throws parseexception{
    string action = request.getparameter("action");
    modelandview mav=new modelandview();
    if("register".equals(action)) {
      //注册
      string email = request.getparameter("email");
      service.processregister(email);//发邮箱激活
      mav.addobject("text","注册成功");
      mav.setviewname("register/register_success");
    }
    else if("activate".equals(action)) {
      //激活
      string email = request.getparameter("email");//获取email
      string validatecode = request.getparameter("validatecode");//激活码
      try {
        service.processactivate(email , validatecode);//调用激活方法
        mav.setviewname("register/activate_success");
      } catch (serviceexception e) {
        request.setattribute("message" , e.getmessage());
        mav.setviewname("register/activate_failure");
      }
    }
    return mav;
  }
  
}
