Hi i am just starting with spring and JPA. And all i want to start with is to connect to a remote db and create the entities that i have on my spring app.
I have a Maria DB server 5.7.24 in a VPS.
I have created a package named domain at /JpaTest/src/main/java/domain . And inside i have an object - Entity like this.
package domain;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity @Table(name="users")
public class User
{
@Id @GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String username;
private String password;
private String name;
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 getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
And my application.properties are like this...
spring.datasource.url=jdbc:mysql://URL:Port/dbName
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.username=admin_customer
spring.datasource.password=*********
spring.jpa.hibernate.ddl-auto=create
spring.jpa.show-sql = true
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
Like this, the program runs as a Spring boot app. But it creates no table. I have tried using spring.jpa.hibernate.ddl-auto=update
, to change the Dialect to other versions, even go with org.hibernate.dialect.MariaDBDialect
, or org.mariadb.jdbc.Driver
and more.
But it just cant work. When i use any dialect or driver other than MySQL, the program cant run because it cant find them. When i use the settings above it executes but it does nothing.
You should add @Column(name = "name")
before column
and check your application config class have: @EntityScan("some.known.persistence")
