Question

Я пытаюсь сгенерировать сущности из базы данных SQL Server и сгенерировать указанные таблицы в базу данных MySQL. Я успешно сгенерировал сущности с помощью инструментов JPA, и теперь у меня есть сущности, подобные этой:

@Entity
//It was originally the @Table annotation, I changed it just to see if
//it would work like this
@TableGenerator(name="AGENCY",schema="amex_digital_test_dev")
@NamedQuery(name="Agency.findAll", query="SELECT a FROM Agency a")
public class Agency implements Serializable {
private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(unique=true, nullable=false)
private int IDAgency;

@Column(name="Channel_Code")
private String channel_Code;

@Column(name="CodiceOAM")
private String codiceOAM;

@Column(name="DistributionList")
private String distributionList;

@Column(name="IsSimpleSignature")
private boolean isSimpleSignature;

@Column(name="Name", nullable=false)
private String name;

public Agency() {
}

public int getIDAgency() {
    return this.IDAgency;
}

public void setIDAgency(int IDAgency) {
    this.IDAgency = IDAgency;
}

public String getChannel_Code() {
    return this.channel_Code;
}

public void setChannel_Code(String channel_Code) {
    this.channel_Code = channel_Code;
}

public String getCodiceOAM() {
    return this.codiceOAM;
}

public void setCodiceOAM(String codiceOAM) {
    this.codiceOAM = codiceOAM;
}

public String getDistributionList() {
    return this.distributionList;
}

public void setDistributionList(String distributionList) {
    this.distributionList = distributionList;
}

public boolean getIsSimpleSignature() {
    return this.isSimpleSignature;
}

public void setIsSimpleSignature(boolean isSimpleSignature) {
    this.isSimpleSignature = isSimpleSignature;
}

public String getName() {
    return this.name;
}

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

 }

Я запускаю процесс, перейдя в JPA Tools -> Создать таблицы из сущностей, и появляется всплывающее окно:

Я нажимаю «Готово», и затем появляется консоль, она не выдает ошибок, но ничего не делает:

Есть ли что-то, что я делаю не так? Это сэкономило бы мне много времени на создание таких таблиц. Заранее спасибо за помощь!

РЕДАКТИРОВАТЬ: Просто добавив одну вещь здесь: я просто использую проект JPA / Maven

Попробуйте сгенерировать БД, запустив отдельное Java-приложение.

public static void main(String...args){
    EntityManager em = Persistence.createEntityManagerFactory("JPAAmex").createEntityManager(); 
}

Генерация таблиц из сущностей с EclipseLink ничего не делает
