That’s the configuration details for user authentication using Spring Security. ![]() Public class MyUserDetails implements UserDetails ]]And to show the Logout button: Import .authority.SimpleGrantedAuthority So create the MyUserDetails class with the following code: package net.codejava Implement UserDetailsNext, we need to create a class that implements the UserDetails interface as required by Spring Security. So we declare this method for convenience. Note that this method returns a single User object if username found, whereas the JPA’s convention method returns a List collection. At runtime, Spring will generate implementation class that provides all CRUD operations.And we declare the getUserByUsername() method with an embedded query to select user details by username. }You see, this interface extends the CrudRepository interface from Spring Data JPA. Public interface UserRepository extends CrudRepository u FROM User u WHERE u.username = :username") Code UserRepository classNext, create the UserRepository interface with the following code: package net.codejava Its fields are mapped to columns of the table in database. }You see, this is a pretty simple model class annotated with JPA annotations. getters and setters are not shown for brevity Public class User = GenerationType.IDENTITY) So create the User class with the following code: package net.codejava Code User classTo use Spring Data JPA, we need to code a model class that maps with the users table in the database. Update URL, username and password according to your MySQL database. =passwordNote that the first line tells Hibernate won’t create tables upon startup. Configure data source propertiesNext, we need to specify the database connection information in the application.properties files as follows: -auto=none We don’t specify version of these dependencies because Spring Boot already defines the default versions in the Spring Boot starter parent dependency. Declare dependenciesFor Spring Data JPA and Hibernate, we need to declare the following dependency in Maven build file: Create the userstable with the following columns: For MySQL script to create this table and insert dummy user details, refer to this tutorial. Create users tableFirst, we need to create a table in MySQL database to store the credentials. The view layer is based on Thymeleaf templates.We will secure an existing Spring Boot application, ProductManager – which is described in this tutorial. The credentials are stored in MySQL database, and Spring Data JPA with Hibernate is used for the data access layer. In other words, securing webpages in Java web applications based on Spring framework using Spring Security APIs. ![]() Throughout this Spring Boot tutorial, you will learn to implement login and logout (authentication) in a Spring Boot application. ![]()
