未创建表，在 Spring Boot 中的多个应用程序中使用来自 maven jar 依赖项的实体

Question

Having Two Projects

1. my-app

2. my-entities

I have my entities in my-entities and i uploading this repository to bitbucket fro hosting then using same repository in my "my-app" project which is a spring boot application and containing database configs like username, dbname, password and i am using spring data jpa with

spring.jpa.hibernate.ddl-auto=update

Sample Entity class present in my-enties

@Entity
public class OrganisationDetails {

    @Id
    @GeneratedValue
    private Long id;


    private String name;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "OrganisationDetails{" +
                "id=" + id +
                ", name='" + name + '\'' +
                '}';
    }
}

But tables are not created automatically.

Answer 1

spring.jpa.hibernate.ddl-auto=update - is used to update the current schema

spring.jpa.hibernate.ddl-auto=create - is used to create new schema

Normally in development phases the combination - create-drop is used

spring.jpa.hibernate.ddl-auto=create-drop

Another vital thing is to specify your SQL dialect. For example for MySql5

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
