Change database schema used by Spring Boot

spring.jpa.properties.hibernate.default_schema=your_scheme

OR

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

spring:
  jpa:
    properties:
      hibernate:
        default_schema: your_schema_name

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

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
