The setters and getters are now shown for brevity, so be sure you generate those methods as well.Next, create a new interface named UserRepository to act as a Spring Data JPA repository with the following simple code: package net.codejava }As you can see, the user information consists of ID, email, password, first name and last name. Private String = "last_name", nullable = false, length = 20) Private String = "first_name", nullable = false, length = 20) Private Long = false, unique = true, length = 45) Public class User = GenerationType.IDENTITY) Code Entity Class and Repository InterfaceNext, create a new Java class named User to map with the corresponding users table (not yet created) in the database, with the following code: package net.codejava format_sql=trueNote that we set the -auto to create in order to let Hibernate create the tables when we run a unit test in the next section. Enter the following properties for configuring a data source that will be used by Spring Data JPA: -auto=create Then open the Spring Boot configuration file application.properties under /src/main/resources directory. Create Database and Configure Data SourceUse MySQL Workbench or MySQL Command Line Client program to create a new database named codejavadb(you can choose any name you want): create database codejavadb Spring Boot uses JUnit 5 (JUnit Jupiter) by default, and the exclusion means that no support for older versions of JUnit. You can also notice the IDE includes the dependency for JUnit automatically:
Spring Boot DevTools is optional but I recommend it, for using the Spring Boot automatic reload feature to save development time.
And choose these dependencies: Spring Web, Thymeleaf, Spring Data JPA, MySQL Driver, Spring Security and Spring Boot DevTools – so the XML code for these dependencies in the pom.xml file is as follows: Create Spring Boot Project and Configure DependenciesIn Spring Tool Suite, create a new Spring Starter project with type Maven and language Java. You can use the latest versions of these software programs. MySQL Community server and MySQL Workbench.HTML 5 and Bootstrap 4 for responsive user interfaceĪnd to follow this tutorial, make sure that you have these software programs installed on your computer:.Spring Security for authentication, login and logout.Spring Data JPA with Hibernate framework or the data access layer.You will go through the process of coding a Spring Boot project using the following technologies:
Through this Spring Boot tutorial, I’d love to guide you to develop a Java web application from scratch with the essential features: user registration, login, logout and view users list – with user information stored in MySQL database.
