如何使用angular js动态更改网页上的状态消息以获得各种结果

Question

I am trying to develop a web application in which there were options of adding actor,modifying,searching,removing. 我正在尝试开发一个Web应用程序，其中可以选择添加actor，修改，搜索，删除。 my requirement is to have message of actor added sucesfully for add actor and actor modified sucessfully,these messages are sent by their respective servlets to statusMessage.html.i want to have only one statusMessage.html for various messages. 我的要求是要成功添加actor消息，以便成功添加add actor和actor，这些消息由它们各自的servlet发送到statusMessage.html.i，对于各种消息，我只希望有一个statusMessage.html。

my servlet is AddActor.java 我的servlet是AddActor.java

package com.flp.fms.controller;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.flp.fms.service.ActorServiceImpl;
import com.flp.fms.service.IActorService;

public class AddNewActor extends HttpServlet {
    private static final long serialVersionUID = 1L;

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        try
        {
            response.setContentType("text/html");  
            IActorService actorService=new ActorServiceImpl();
            Map<String,String> actorDetails=new HashMap<String,String>();
            actorDetails.put("firstName", request.getParameter("firstName"));
            actorDetails.put("lastName", request.getParameter("lastName"));

            if(actorService.AddActor(actorDetails))
            {
                response.sendRedirect(request.getContextPath() +"/htmlTemplates/statusMsg.html");
            }
        }
        catch (Exception e) {
            // TODO: handle exception
        }
    }
}

my statusMsg.html is 我的statusMsg.html是

<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Status</title>
        <link rel="stylesheet" href="style.css">
        <script type="text/javascript" src="../script/angular.min.js"></script>
        <script type="text/javascript" src="../script/angular-route.min.js">></script>

        <script type="text/javascript" src="../script/appConfig.js"></script>
        <script type="text/javascript" src="../script/appCtrl.js"></script>
</head>
<body ng-app="myApplication">
<img src='../static/bg.png' width="1280" height="222"/>
<a href="Welcome.html" class="show_buttton button1">Home</a>
<div ng-controller="status">
    <h1 align=center>{{message}}</h1>
</div>
</body>
</html>

My Controller is 我的控制器是

app.controller('status',function($scope,$http){
    var url='http://localhost:8018/angularjs_webapp/statusMsg';

    $http.get(url)
        .success(function(response){
            $scope.message=response;
        });
});

my statusMsg.java is 我的statusMsg.java是

package com.flp.fms.controller;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.google.gson.Gson;

public class statusMsg extends HttpServlet {
    private static final long serialVersionUID = 1L;

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String message=(String) request.getAttribute("message");
        PrintWriter out=response.getWriter();
        response.setContentType("application/json");

        Gson gson=new Gson();
        String myGsonMsg=gson.toJson(message);
        out.println(myGsonMsg);
    }
}

Answer 1

Using sendRedirect method in your AddActor.java servlet redirects request coming in this service to the statusMsg.java servlet. 在AddActor.java Servlet中使用sendRedirect方法会将在此服务中出现的请求重定向到statusMsg.java Servlet。

Your can use getRequestDispathcer(URL).forward(request, response) in your AddActor.java servlet where you can push response as a request to the statusMsg.java servlet. 您可以在AddActor.java Servlet中使用getRequestDispathcer（URL）.forward（request，response），在其中您可以将响应作为请求推送到statusMsg.java Servlet。
