Building a File Processing Batch with Spring Boot and MySQL Integration

Spring Batch is a powerful framework for batch processing in Java applications, and it integrates seamlessly with Spring Boot for building robust and scalable batch processing systems. In this tutorial, we’ll cover the basics of setting up a Spring Boot project with Spring Batch and provide examples to help you get started.


  • Basic understanding of Java and Spring Framework.
  • Java Development Kit (JDK) installed (version 8 or later).
  • Integrated Development Environment (IDE) like IntelliJ IDEA or Eclipse.
  • Maven or Gradle for dependency management.

Step 1: Setup Spring Boot Project

Start by creating a new Spring Boot project. You can use Spring Initializr ( or your preferred IDE to generate a new project with the following dependencies:

  • Spring Batch
  • Spring Data JPA
  • MySQL Driver
  • Spring Web (optional, for REST endpoints)

Step 2: Create Entity and Repository

Create an entity class to represent the data you want to insert into the database. For example:

Create a repository interface for this entity:

Step 3: Define Job Configuration

Create a configuration class for the Spring Batch job. This class will define the steps to read from a file, process the data, and write it to the database.

Step 4: Define Item Processor

Create an item processor class to process each item read from the file. This class will typically perform any necessary data transformations.

Step 5: Create Job Completion Listener

Create a job completion listener to handle events after the batch job completes.

Step 6: Prepare Data File

Prepare a CSV file named data.csv with columns matching the entity fields.

Step 7: Configure MySQL Database

Configure the MySQL database connection in or application.yml:


Step 8: Run the Application

Run the Spring Boot application, and the batch job will automatically read the data from the CSV file, process it, and insert it into the MySQL database.


In this tutorial, you’ve learned how to create a Spring Boot batch application to process files and insert the data into a MySQL database. By following the steps outlined above, you can build robust batch processing applications to handle large volumes of data efficiently.
