To implement intended redirects for logged in users in your existing project using Java, Maven, MVC, servlets, and JSPs, you would need to perform the following steps:

1. Create a new RedirectController class that will handle the intended redirects based on user role or any other condition. This class should be part of the controller package.

2. In the RedirectController class, create a method like redirectUser(HttpServletRequest request, HttpServletResponse response) that will handle the redirection logic for logged-in users.

Here's an example of how the RedirectController class might look:

java
 
 
Copy code
package com.example.controller;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class RedirectController {

    public void redirectUser(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        if (request.getSession().getAttribute("user") != null) {
            // User is logged in, perform redirect based on condition
            // For example, if the user has admin role, redirect to admin page, else redirect to user dashboard.
            User currentUser = (User) request.getSession().getAttribute("user");

            if (currentUser.getRole().equals("admin")) {
                response.sendRedirect(request.getContextPath() + "/admin/dashboard");
            } else {
                response.sendRedirect(request.getContextPath() + "/user/dashboard");
            }
        } else {
            // User is not logged in, redirect to login page
            response.sendRedirect(request.getContextPath() + "/login");
        }
    }
}

1. Modify your existing login servlet or any other relevant servlet to use the RedirectController for redirecting logged-in users.

Here's an example of how the login servlet might look with the redirect logic:

java
 
 
Copy code
package com.example.servlet;

import com.example.controller.RedirectController;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class LoginServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // Process login request
        // ...

        // After successful login
        RedirectController redirectController = new RedirectController();
        redirectController.redirectUser(request, response);
    }
}

1. Update your servlet mappings in the web.xml file, if necessary, to include the new RedirectController and the updated servlets.

2. Update your JSP files to handle the redirected pages. For example, you would create an adminDashboard.jsp file and a userDashboard.jsp file, each containing the relevant content for the corresponding user role.

Note: Make sure you have the necessary dependencies and configurations set up in your Maven project, such as the servlet API, JSTL, and the mapping of servlets and JSPs.

Remember to adapt the code to fit your project's specific needs, and adjust the class and package names as appropriate.

Angular is an open-source web application framework based on Typescript that is used to build and maintain dynamic web applications. It is the most popular front-end development framework among developers and is developed and maintained by Google. Angular follows the MVC (Model-View-Controller) architecture.

Code example:

javascript
 
 
Copy code
//importing Angular
import { NgModule } from '@angular/core';

//decorator
@NgModule({

})
