We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration. 22 | 23 | In this course, you will learn the basics developing a Basic Todo Management Application using Spring Boot with Login and Logout functionalities. 24 | 25 | You will build the website step by step - in more than 25 steps. This course would be a perfect first step as an introduction to Java Web Application Development. 26 | 27 | You will be using Spring (Dependency Management), Spring MVC, Spring Boot, Spring Security (Authentication and Authorization), BootStrap (Styling Pages), Maven (dependencies management), Eclipse (IDE) and Tomcat Embedded Web Server. We will help you set up each one of these. 28 | 29 | You will learn about 30 | - Basics of Spring Boot 31 | - Basics of Autoconfiguration and Spring Boot Magic 32 | - DispatcherServlet 33 | - Basic Todo Management Application with Login/Logout 34 | - Model, Controllers, ViewResolver and Filters 35 | - Forms - DataBinding, Validation 36 | - Annotation based approach - @RequestParam, @ModelAttribute, @SessionAttributes etc 37 | - Bootstrap to style the page 38 | - Spring Security 39 | - Exception Handling 40 | 41 | ### Step Wise Details 42 | - Step 01: Basic Spring Boot Web Application Setup 43 | - Step 02: First Spring MVC Controller, @ResponseBody, @Controller 44 | - Step 03: Demystifying some of the Spring Boot magic 45 | - Step 04: Redirect to Login JSP - LoginController, @ResponseBody and View Resolver 46 | - Step 05: Show userid and password on the welcome page - ModelMap and @RequestParam 47 | - Step 06: DispatcherServlet and Spring MVC Flow 48 | - Step 07: Your First HTML form 49 | - Step 08: Add hard-coded validation of userid and password 50 | - Step 09: Magic of Spring 51 | - Step 10: Create TodoController and list-todos view. Make TodoService a @Service and inject it. 52 | - Step 11: Architecture of Web Applications 53 | - Step 12: Session vs Model vs Request - @SessionAttributes 54 | - Step 13: Add new todo 55 | - Step 14: Display Todos in a table using JSTL Tags 56 | - Step 15: Bootstrap for Page Formatting using webjars 57 | - Step 16: Let's delete a Todo 58 | - Step 17: Format Add Todo Page and Adding Basic HTML5 form validation 59 | - Step 18: Introduce JSR 349 Validations using Hibernate Validator - First Command Bean. 60 | - Step 19: Updating a todo 61 | - Step 20: Let's add a Target Date for Todo - Use initBinder to Handle Date Fields 62 | - Step 21: JSP Fragments and Navigation Bar 63 | - Step 22: Preparing for Spring Security 64 | - Step 23: Initial Spring Security Setup 65 | - Step 24: Refactor and add Logout Functionality using Spring Security 66 | - Step 25: Exception Handling 67 | 68 | --- 69 | 70 | - We do NOT interact with a Database in this Beginner’s Course. 71 | - We will be building a traditional JSP based web application in this course. 72 | 73 | --- 74 | 75 | ### Expectations 76 | - You should know Java. You should understand usage of Annotations. 77 | - You should understand the basics of Spring framework. 78 | - You are NOT expected to have any experience with Eclipse or Maven. 79 | - We will help you install Eclipse and get up and running with Maven. 80 | 81 | ## Let's have some fun 82 | - What are we waiting for? 83 | - Let's have some fun building a web application Spring Boot in 25 Steps. 84 | - I had fun creating this course and hope you would too. 85 | - Thanks for your interest in Our Course 86 | - I hope you’re as excited as I am! 87 | - If you’re ready to learn more and sign up for the course, 88 | - go ahead and hit that Enroll button, 89 | - or take a test drive by using the Free Preview feature. 90 | - See you in the course! 91 | 92 | ## Getting Started 93 | - Eclipse - https://courses.in28minutes.com/p/eclipse-tutorial-for-beginners 94 | - Maven - https://courses.in28minutes.com/p/maven-tutorial-for-beginners-in-5-steps 95 | - JUnit - https://courses.in28minutes.com/p/junit-tutorial-for-beginners 96 | - Mockito - https://courses.in28minutes.com/p/mockito-for-beginner-in-5-steps 97 | 98 | ## About in28Minutes 99 | 100 | At in28Minutes, we ask ourselves one question everyday 101 | > How do we create more amazing course experiences? 102 | > We use 80-20 Rule.

"adding elements directly to the HttpServletRequest (as request attributes) would seem to serve the same purpose. The reason to do this is obvious when taking a look at one of the requirements we have set for the MVC framework: It should be as view-agnostic as possible, which means we’d like to be able to incorporate view technologies not bound to the HttpServletRequest as well." - Rod Johnson et. al’s book Professional Java Development with the Spring Framework 6 | - Spring documentation states that the @SessionAttributes annotation “list the names of model attributes which should be transparently stored in the session or some conversational storage.” 7 | 8 | ## Useful Snippets and References 9 | First Snippet 10 | ``` 11 | @SessionAttributes("name") 12 | ``` 13 | 14 | ## Files List 15 | 16 | ### pom.xml 17 | 18 | ```xml 19 | 20 | 22 | 4.0.0 23 | 24 | com.in28minutes.springboot.web 25 | spring-boot-first-web-application 26 | 0.0.1-SNAPSHOT 27 | jar 28 | 29 | spring-boot-first-web-application 30 | Demo project for Spring Boot 31 | 32 | 33 | org.springframework.boot 34 | spring-boot-starter-parent 35 | 1.4.3.RELEASE 36 | 37 | 38 | 39 | 40 | UTF-8 41 | UTF-8 42 | 1.8 43 | 44 | 45 | 46 | 47 | org.springframework.boot 48 | spring-boot-starter-web 49 | 50 | 51 | 52 | org.apache.tomcat.embed 53 | tomcat-embed-jasper 54 | provided 55 | 56 | 57 | 58 | org.springframework.boot 59 | spring-boot-devtools 60 | runtime 61 | 62 | 63 | 64 | org.springframework.boot 65 | spring-boot-starter-test 66 | test 67 | 68 | 69 | 70 | 71 | 72 | 73 | org.springframework.boot 74 | spring-boot-maven-plugin 75 | 76 | 77 | 78 | 79 | 80 | ``` 81 | --- 82 | ### src/main/java/com/in28minutes/springboot/web/controller/LoginController.java 83 | 84 | ```java 85 | package com.in28minutes.springboot.web.controller;
