我正在使用 Hibernate 制作模型类，但我不知道如何处理这种关系。

我有三张桌子。

地址、员工和个人。

一个雇员可以有一个地址，一个人可以有一个地址。

不知道怎么映射。

因为我想使用嵌入式注释但不起作用。

首先是映射我的类，我需要把这两个实体放在地址类中吗？

我需要使用什么样的注释？

我使用具有 id 属性的超类，并且每个类都扩展。

我正在使用 mysql

我的人班

@Entity
@Table(name = "destinatario")
public class Destinatario extends Persistent {

        private static final long serialVersionUID = -7091318100871934315L;

        @ManyToOne(cascade = CascadeType.PERSIST)
        @JoinColumn(name = "endereco_id", referencedColumnName = "id")

我通过 xml 源运行和创建人的方法

public static void main(String[] args) {

        new Processadora().extrairDadosXml("diego");

        ArquivoNotaFiscal arquivoNotaFiscal = null;
        Destinatario destinatario = null;
        NotaFiscal notaFiscal = null;

        destinatario = createDestinatario();
        arquivoNotaFiscal = createArquivoNotaFiscal();
        notaFiscal = createNotaFiscal(arquivoNotaFiscal, emitente, destinatario);

        destinatario.setNotaFiscais(Arrays.asList(notaFiscal));

        DestinatarioDAO<Destinatario> destinatarioDAO = new DestinatarioDAOImpl<>();

        Session session = HibernateSessionFactory.getSession();
        Transaction transaction = session.getTransaction();
        transaction.begin();

        destinatarioDAO.save(destinatario);

        transaction.commit();
}

private static Destinatario createDestinatario() {

        Destinatario destinatario = new Destinatario();

        Endereco endereco = new Endereco();

        endereco.setLogradouro(nFeProc.getNfe().getInfNFe().getDestinatario().getEndereco().getLogradouro());
        endereco.setNumero(nFeProc.getNfe().getInfNFe().getDestinatario().getEndereco().getNumero());
        endereco.setBairro(nFeProc.getNfe().getInfNFe().getDestinatario().getEndereco().getBairro());
        endereco.setComplemento(nFeProc.getNfe().getInfNFe().getDestinatario().getEndereco().getComplemento());
        endereco.setCep(nFeProc.getNfe().getInfNFe().getDestinatario().getEndereco().getCep());
        endereco.setMunicipio(nFeProc.getNfe().getInfNFe().getDestinatario().getEndereco().getMunicipio());
        endereco.setUf(UF.valueOf(nFeProc.getNfe().getInfNFe().getDestinatario().getEndereco().getUF()));
        endereco.setTelefone(nFeProc.getNfe().getInfNFe().getDestinatario().getEndereco().getTelefone());

        destinatario.setEndereco(endereco);

        destinatario.setRazaoSocial(nFeProc.getNfe().getInfNFe().getDestinatario().getRazaoSocial());
        destinatario.setInscricaoEstadual(nFeProc.getNfe().getInfNFe().getDestinatario().getInscricaoEstadual());
        destinatario.setInscricaoSuframa(nFeProc.getNfe().getInfNFe().getDestinatario().getInscricaoSuframa());
        destinatario.setEmail(nFeProc.getNfe().getInfNFe().getDestinatario().getEmail());
        destinatario.setCnpj(nFeProc.getNfe().getInfNFe().getDestinatario().getCnpj());
        destinatario.setCpf(nFeProc.getNfe().getInfNFe().getDestinatario().getCpf());

        return destinatario;

}

我发现了我的问题，我只保存了一个对象，因为我认为如果我对包含其他对象的对象使用保存，它将保存，但我需要先保存地址，然后再保存人。

所以这种方式一切正常。
