How to Add a Public Landing Page

By Known-Space -


If an application to have a landing page that is accessible to everyone at first, the user can then signup or login to access specific features. For achieve this we can add a public view page and set up the security constraints to allow access to the view page.
In this example, we have a view page that anyone can access. Then they can click the link to access the secure pages.
This project has the following mods
1. Updated security configs to allow public access to landing page
2. Updated controller to send requests to landing page
3. New landing page

Details below
---

1. Updated security configs to allow public access to landing page
See the config below. It will "permit all" access to the landing page "/".  Also, for successful logout it will redirect to the landing page "/"
File: DemoSecurityConfig.java

2. Updated controller to send requests to landing page
In the controller file, added new "/" mapping to send to landing page. And changed the original home mapping to "/employees". see changes in bold.
File: DemoController.java

3. New landing page
Created a new view page for landing information. Anyone can access this page
File: src/main/webapp/WEB-INF/view/landing.jsp

To test the application, be sure to open a new private/incognito window.
Now when you run the application, anyone can access the public home page without logging in. If they follow through on the link, then they will be required to login.

What is a Web Server? A web server is software and hardware that uses  HTTP  (Hypertext Transfer Protocol) and other protocols to respond to  client  requests made over the World Wide Web. The main job of a web server is to display website content through storing, processing, and delivering webpages to users. Besides HTTP, web servers also support  SMTP  (Simple Mail Transfer Protocol) and FTP (File Transfer Protocol), used for email, file transfer, and storage. Web servers are  used in web hosting  or the hosting of data for websites and web-based applications -- or web applications. How do web servers work? Web server software is accessed through the domain names of websites and ensures the delivery of the site's content to the requesting user. The software side is also comprised of several components, with at least an HTTP server. The HTTP server is able to understand HTTP and URLs. As hardware, a web server is a computer that stores web server software and other files related t

Use @Initbinder in Spring MVC

By Known-Space -

In this blog we will learn how to use @initbinder Annotation in Spring MVC. We will walk through a small example with help of a demo application. If you’re familiar with MVC architecture ,you must all be aware that controller is used for processing the web request and rendering the response to the View. Now,Initbinder comes into picture if you want to customize the request being sent to the controller.It is defined in the controller, helps in controlling and formatting each and every request that comes to it. This annotation is used with the methods which initializes  WebDataBinder  and works as a preprocessor for each request coming to the controller. InitBinder interaction with other Components Seems lot of gyaan right ! So,now to explain this let’s take an example. Consider we have student management portal for a school ,which manages the information of all the students present in the school.It has a feature for registering a student when he is admitted to the school.

CSRF Protection using Synchronizer Tokens

What is cross site request forgery? Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they're currently  authenticated. CSRF attacks specifically target state-changing requests,  not theft of data, since the attacker has no way to see the response to the forged request We can avoid these kind of attack (CSRF) by two ways 1. Synchronizer Tokens 2. Double submitted cookies Here we are considering on Synchronize Tokens. When we login, there will be a random number generated and stored on the client side and server side as well. So when the attacker creates the code he doesn't know the token value. So he can not create a code with the correct token value. Anyhow, if the victim clicks the link, that won't be harmful. because the verification will fail. For the first step we want to create the session in the client side (index.php). Then we want create a cookies and set session id to the cook

CSRF Protection using Double Submitted Cookies

Here we will look about the Double Submitted Cookies to CSRF protection. In Synchronizer Token the client and the server should wants to generate the token value. So this process is time consuming and get load the server. For reduce this kind of issues we are using double submitted cookies. We need java script to run double submitted cookies. For that the http flag should be off. Here we are sending two cookies through the http header and the http body. Then the server will validate these two cookies and if its same it will allow, if its not deny the request. In the client side (index.php) we create the session and store it in the cookie.After that create a token and store it in a new cookie. After that we shoud set the estimation of hidden token as "<? echo $token ?>" This will send the hidden token to server side when client click on login button. After that create a function to validate login in the server side Get the full code from here

Add Logging Messages in Spring 5.1 - All Java Config Version

Add Logging Messages in Spring 5.1 - All Java Config Version The Problem In Spring 5.1, the Spring Development team changed the logging levels internally. As a result, by default you will no longer see the red logging messages at the INFO level. This is different than in the videos. The Solution If you would like to configure your app to show similar logging messages as in the video, you can make the following updates. Note, you will not see the EXACT same messages, since the Spring team periodically changes the text of the internal logging messages. However, this should give you some additional logging data. Overview of the steps 0. Create a logging properties file 1. Create a configuration class to configure the parent logger and console handler Detailed Steps 0. Create a logging properties file This properties file will define the logging levels for the application. The props file sets the logger level to FINE. For more detailed logging info, you can s

The TRUE difference between [] and {{}} bindings in Angular

By Known-Space -
  One of the parts of Angular that most developers think they understand, but many don’t, is the true nature of [] and {{}} bindings. A fundamental lack of understanding of these bindings can become a major issue when working with templates and trying to get them to do exactly what you want. It can also be the cause of spending an unnecessary amount of hours trying to figure out a bug. So I’m going to run down exactly what these two bindings do, and what it is that many developers misunderstand about them. You’re probably familiar with the typical usage of {{}} bindings: <h1>{{title}}</h1> And you’re probably familiar with the typical usage of [] or property bindings: <img [src]="imgsrc"> But do you truly understand what each binding is doing? And why we use them in this situation? Many if not most developers simply know to use {{}} when putting text in an element, and [] for binding to properties. But have you ever wondered with reactive forms why the  form
