Hibernate not updating schema automatically - postgresql

Question

I am using SpringBoot with Hibernate. I have 2 Postgres datasources. I have an existing database (pims) and a new database (powwow), and some entities. When I start up SpringBoot, I would like it to automatically create the tables in the new powwow database, however it is not doing so.
application.properties
# pims datasource
spring.datasource1.driver-class-name=org.postgresql.Driver
spring.datasource1.jdbc-url=jdbc:postgresql://localhost:5432/pims
spring.datasource1.username=postgres
spring.datasource1.password=postgres
# powwow datasource
spring.datasource2.driver-class-name=org.postgresql.Driver
spring.datasource2.jdbc-url=jdbc:postgresql://localhost:5432/powwow
spring.datasource2.username=postgres
spring.datasource2.password=postgres
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.database-platform=postgres
spring.jpa.hibernate.ddl-auto=update
#spring.jpa.properties.hibernate.hbm2ddl.auto=update
#spring.jpa.generate-ddl=true
#spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.datasource2.dbcp2.test-while-idle=true
spring.datasource2.dbcp2.validation-query=select 1
spring.jpa.hibernate.naming.implicit-strategy=org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyHbmImpl
spring.jpa.hibernate.naming.physical-strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy
# logging
logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
Example entity:
PowWowActivityEntity.java
#Entity
#Table(name = "powwowactivity")
public class PowWowActivityEntity {
#Id
#Column(name = "activity_id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long activity_id;
#Column(name = "status")
private String status;
Output

Question
I thought by adding the following line, the new tables would automatically be created by updating the schema. Any ideas? Is this not working because I have more than one datasource?
spring.jpa.hibernate.ddl-auto=update

Answer 1

The reason it was not working is because i have 2 datasources defined. If i change the config to update, it works (properties.put("hibernate.hbm2ddl.auto", "update");):
#Bean(name = "powwowEntityManager")
#Primary
public LocalContainerEntityManagerFactoryBean powwowEntityManager() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(powwowDataSource());
em.setPackagesToScan(new String[] { "com.clubtravel.powwow.entities.powwow" });
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
em.setJpaVendorAdapter(vendorAdapter);
HashMap<String, Object> properties = new HashMap<>();
// properties.put("hibernate.hbm2ddl.auto",env.getProperty("hibernate.hbm2ddl.auto"));
// properties.put("hibernate.dialect",env.getProperty("hibernate.dialect"));
properties.put("hibernate.hbm2ddl.auto", "update");
properties.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
em.setJpaPropertyMap(properties);
logger.info("Setting spring.datasource2 (powwowEntityManager) hibernate.hbm2ddl.auto = "+env.getProperty("hibernate.hbm2ddl.auto")+" and hibernate.dialect = "+env.getProperty("hibernate.dialect"));
return em;
}
