Change database schema used by Spring Boot

Java Problem Overview

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.

Java Solutions

Solution 1 - Java

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

Solution 2 - Java

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.

Solution 3 - Java

spring:
  jpa:
    properties:
      hibernate:
        default_schema: your_schema_name

Solution 4 - Java

spring.jpa.properties.hibernate.default_schema=your_scheme

spring: jpa: properties: hibernate.default_schema: your_scheme

With HikariDataSource for example spring.jpa.properties.hibernate.default_schema is ignored and you have to set too

spring.datasource.hikari.schema=your_scheme

Solution 5 - Java

I was hitting error: Cannot acquire connection from data source org.postgresql.util.PSQLException: ERROR: unsupported startup parameter: search_path

Solution: application-xyz_dev.yml

url: jdbc:postgresql://localhost:8080/your_database?search_path=your_scheme&stringtype=unspecified
