Batch Processing Using Spring boot

This demo uses in memory H2 database for tracking the batch details and as part of batch processing it reads a CSV file present in resource directory and saves the content into the H2 database.

*** NOTE: The CSV file path is absolute if anyone copying this code for testing need to change the file path in application.properties.

Sample queries for checking if records saved into H2 database or not and checking batchjob status.

• select * FROM USER;
• select * from BATCH_JOB_EXECUTION;
• select * from BATCH_STEP_EXECUTION;
• select * from BATCH_JOB_INSTANCE;
• select * FROM BATCH_JOB_EXECUTION_CONTEXT;
• select * FROM BATCH_STEP_EXECUTION_CONTEXT;
• select * FROM BATCH_JOB_EXECUTION_PARAMS;

• http://localhost:8081/h2-console/ : For checking h2 database console.
• http://localhost:8081/load : Load data from CSV to database.
