Change database schema used by Spring Boot

Question

How do I specify database schema used by Spring Boot? I am using default hibernate (=default) and postgres (but i hoping for a generic solution). I know how to specify JDBC URL:

spring.datasource.url=jdbc:postgresql:db_name 

But unfortunately postgresql does not allow to specify schema in JDBC URL. I know that there is hibernate property hibernate.default_schema, so I was hoping that one of the following properties will work:

hibernate.default_schema=schema spring.hibernate.default_schema=schema spring.jpa.hibernate.default_schema=raw_page 

But unfortunately neither of them seems to have any result.

Answer 1

Use for application.properties:

spring.jpa.properties.hibernate.default_schema=your_scheme  

OR for application.yaml:

spring:   jpa:     properties:       hibernate.default_schema: your_scheme 

From the Spring Boot reference guide:

all properties in spring.jpa.properties.* are passed through as normal JPA properties (with the prefix stripped) when the local EntityManagerFactory is created

See http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-configure-jpa-properties

For a full list of available properties see http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-configure-jpa-properties

Answer 2

It depends on the DataSource implementation which property has to be used to set the default schema (reference). With HikariDataSource for example spring.jpa.properties.hibernate.default_schema is ignored and you have to set

spring.datasource.hikari.schema=schema 

See the complete list of HikariCP configuration parameters here.
