Overview of Spring Boot Thymeleaf example
We will build a Spring Boot CRUD example using Thymeleaf template engine for View layer and Spring Data JPA with Database in that:
- Each Course (entity) has id, name, description, price, enabled status.
- CRUD operations are supported: create, retrieve, update, delete Courses.
- User can search Courses by name.
- Create new entity object:
- Retrieve all objects:
- Update status of an item:
- Update an object in its own page:
- Search by name:
- Delete an item:

Project Structure
Let me explain it briefly.
-
Course
class corresponds to entity and table courses. -
CourseRepository
is an interface that extends JpaRepository for CRUD methods and custom finder methods. It will be autowired inCourseController
. CourseController
is a Controller which has request mapping methods for RESTful requests such as: getAll, addCourse, saveCourse, editCourse, deleteCourse, updateCourseEnabledStatus.static/css
contains custom css style.template
stores HTML template files for the project.Configuration for Spring Datasource, JPA & Hibernate in
application.properties
.pom.xml
contains dependencies for Spring Boot, Thymeleaf, Bootstrap and Database.
