Spring Boot, Hibernate Search properties

Question

How to provide Hibernate Search parameters when using Spring Boot?

...
spring.datasource.driverClassName=org.postgresql.Driver

hibernate.search.jmx_enabled=true
hibernate.search.default.directory_provider=filesystem
hibernate.search.generate_statistics=true
hibernate.search.lucene_version=LUCENE_CURRENT
hibernate.search.default.indexBase=/mypath-to-index

It does not care what I provide. Default settings always get applied.

I think below code does not have anything to process properties related to Hibernate Search. Can that be the issue?

Answer 1

You can put them in the application.properties file if you put "spring.jpa.properties." in front of the property names.

Example:

spring.jpa.properties.hibernate.search.jmx_enabled=true
spring.jpa.properties.hibernate.search.default.directory_provider=filesystem
spring.jpa.properties.hibernate.search.generate_statistics=true
spring.jpa.properties.hibernate.search.lucene_version=LUCENE_CURRENT
spring.jpa.properties.hibernate.search.default.indexBase=/mypath-to-index

Spring will take any properties under spring.jpa.properties.* and pass them along (with the prefix stripped) once the EntityManagerFactory is created.
