How to enable batch inserts with Hibernate and Spring Boot

by

There is nothing wrong with your code and it’s working properly.

I debugged it and then I installed p6spy and it’s working. This is how you can test it too:

  1. In build.gradle add this dependency:

    compile 'p6spy:p6spy:2.1.4'

  2. Modify the connection properties like this:

    database.driver=com.p6spy.engine.spy.P6SpyDriver
database.url=jdbc:p6spy:postgresql://localhost:5432/

  3. Add spy.properties in the resources folder. You can download it from here.

And then you will see the batched statements:

The third column is batch indicating that the statement were executed in a JDBC batch.

The column right before the one mentioning batch indicates the amount of milliseconds it took to execute the statement. The ones with 0 are for when the statement is added to the batch.

The ones containing statement in the 3rd column (therefore having a 1 or a 2 in the 2nd column) are for when the batch was executed, which corresponds to the 20th and the 30th iteration.
