Why hibernate doesn't create table and schema - postgresql

Question

I am using spring-boot and postgreSQL to develop basic restful service. I try to create table by using JPA, here is the application.properties file
# Disable feature detection by this undocumented parameter. Check the org.hibernate.engine.jdbc.internal.JdbcServiceImpl.configure method for more details.
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults = false
#Default port set
#PostrgreSQL connection
spring.datasource.url=jdbc:postgresql://localhost:5432/mydb
spring.datasource.username=myuser
spring.datasource.password=123456789
spring.jpa.generate-ddl=true
spring.jpa.show-sql = true
#create/create-drop/update/
spring.jpa.hibernate.ddl-auto = create
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.EJB3NamingStrategy
here is the entity
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "User", schema = "public")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "ID")
private Long id;
#Column(name = "USERNAME")
String userName;
#Column(name = "USERSURNAME")
String userSurName;
#Column(name = "USERJOB")
String userJob;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserSurName() {
return userSurName;
}
public void setUserSurName(String userSurName) {
this.userSurName = userSurName;
}
public String getUserJob() {
return userJob;
}
public void setUserJob(String userJob) {
this.userJob = userJob;
}
}
when I run the application, I am expecting User table must be created. But there is no table or schema.
I can not find any error.
here is the log.

Answer 1

I tried to reproduce the same issue but couldn't, here are my steps:
Go to https://start.spring.io and create a demo project with JPA ,
Postgres Dependencies with 1.5.14 version of Spring boot.
Add User Class to the same package where the #SpringBootApplication
class has been placed.
Updated Application.properties with the same properties(Updated DB
details).
Here are the logs hibernate specific:
org.hibernate.tool.hbm2ddl.SchemaExport : HHH000227: Running hbm2ddl
schema export
Hibernate: drop table if exists public.user cascade
Hibernate: drop sequence hibernate_sequence
Hibernate: create table public.user (id int8 not null, userjob
varchar(255), username varchar(255), usersurname varchar(255),
primary key (id))
Hibernate: create sequence hibernate_sequence start 1 increment 1

You can post your pom.xml if you still face issues after the above instructions.
If you want to place the entity classes in a different package from where your SpringBoot Application is placed , you can use do that by providing path of your entities by annotating your SpringBootApplication with
#EntityScan( basePackages = {"package-name"} )
