[RESOLVIDO]Erro Spring

Cledsonjr · Setembro 24, 2012, 8:22am

Bom dia.

Comecei a usar o Spring e estou com um problema.
Quando eu coloco algum relacionamento nas Classes ele não funciona, mas senão tiver relacionamentos funciona.
Devo colocar os relacionamentos no spring.xml?

Segue as classes:

package br.com.autocom.modelo;

import java.io.Serializable;
import java.util.Calendar;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Inheritance;
import javax.persistence.InheritanceType;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.SequenceGenerator;

@SequenceGenerator(name = "Cadastro_Sequencia", sequenceName = "Cadastro_Sequencia")
@Entity
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
public class Cadastro implements Serializable{
	private static final long serialVersionUID = 1L;
	
	@Id
    @GeneratedValue(strategy=GenerationType.AUTO, generator="Cadastro_Sequencia")
	@Column(name="codigoCadastro")
	private Integer codigoCadastro;
	private String razaoSocial;
	private String nomeFantasia;
	private String endereco;
	private String cep;
	private String setor;
	private String complemento;
	private String numero;
	private String obs;
	private String cnpjCPF;
	private Calendar dataAtualizado;
	private Calendar dataCadastro;
	private Calendar dataSuspensao;
	private String email;
	private String InscRg;
	private String cidade;
	private String estado;
	private String telefone1;
	private String celular1;
	private String contato1;
	private String telefone2;
	private String celular2;
	private String contato2;
	
	@ManyToOne (targetEntity=br.com.autocom.modelo.UfCidade.class)  
	@JoinColumn(name="codigoEstadoCidade", nullable=false)  
	private UfCidade ufCidade;

//Getters and Setters omitidos
}

UfCidade.java

[code]
package br.com.autocom.modelo;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToMany;
import javax.persistence.SequenceGenerator;

@Entity
@SequenceGenerator(name = “EstadoCidade_Sequencia”, sequenceName = “EstadoCidade_Sequencia”)
public class UfCidade implements Serializable {
private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy=GenerationType.AUTO, generator="EstadoCidade_Sequencia")
@Column(name="codigoEstadoCidade")
private Integer codigoEstadoCidade;
private String estado;
private String municipio;

private List<Cadastro> cadastro;

Estou meio perdido no Spring. ouço falar de tanta coisa sobre ele que parece que existe vários Springs. É isso mesmo?
Esse que estou usando para a persistência funciona perfeitamente, desde que não exista relacionamentos nas classes.

Como posso consertar esse erro? Vcs me recomendam algum tutorial?

Agradeço a ajuda!

Oi.

O seu tópico está como resolvido, você conseguiu resolver mesmo? Porquê eu estou passando pelo mesmo problema.
Qual a solução que você encontrou?

Obrigado

Apenas mudei os relacionamentos.

Segue as classes editadas:

Cadastro.java

package br.com.autocom.modelo;

import java.io.Serializable;
import java.util.Calendar;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Inheritance;
import javax.persistence.InheritanceType;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.SequenceGenerator;

@SequenceGenerator(name = "Cadastro_Sequencia", sequenceName = "Cadastro_Sequencia")
@Entity
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
public class Cadastro implements Serializable{
	private static final long serialVersionUID = 1L;
	
	@Id
    @GeneratedValue(strategy=GenerationType.AUTO, generator="Cadastro_Sequencia")
	@Column(name="codigoCadastro")
	private Integer codigoCadastro;
	private String razaoSocial;
	private String nomeFantasia;
	private String endereco;
	private String cep;
	private String setor;
	private String complemento;
	private String numero;
	private String obs;
	private String cnpjCPF;
	private Calendar dataAtualizado;
	private Calendar dataCadastro;
	private Calendar dataSuspensao;
	private String email;
	private String InscRg;
	private String telefone1;
	private String celular1;
	private String contato1;
	private String telefone2;
	private String celular2;
	private String contato2;
	
	@ManyToOne
	@JoinColumn(name = "codigoEstadoCidade") 
	private UfCidade ufCidade;

//Getters and Setters omitidos 
}

UfCidade.java

package br.com.autocom.modelo;

import java.io.Serializable;
import java.util.List;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;

@Entity
public class UfCidade implements Serializable {
	private static final long serialVersionUID = 1L;

	@Id
	@Column(name="codigoEstadoCidade")
	@GeneratedValue(strategy=GenerationType.IDENTITY)
	private Integer codigoEstadoCidade;
	private String municipio;
	private String estado;
	
	@OneToMany(cascade = {CascadeType.ALL}, mappedBy = "codigoCadastro")  
	private List<Cadastro> cadastro;

        //Getters and Setters omitidos

Veja se isso te ajuda. Não sei se é a melhor forma, mas comigo agora está funcionando normalmente.
