2) Configurar el Build Path del Proyecto
click derecho sobre el proyecto -> Build path -> Configure Build path
asignar el JRE correcto.
asignar el Server correcto.
3) Agregar las dependencias necesarias en el archivo pom.xml

luego de salvar estos cambios, posiblemente te salga el siguiente error:
esto se soluciona facilmente
click derecho sobre el proyecto -> maven -> Update project
click en [OK]
4) Crear los modelos con los que se trabajará
en src/main/java creamos el package com.cmd.cc.domain
y en él crear el modelo MailingFilter.java
[code]
package com.cmd.cc.domain;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
public class MailingFilter {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
private String name;
private String description;
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
}
[/code]
5) Spring Data JPA Repository
Creamos el package com.cmd.cc.repositories
y en el la interface MailingFilterRepository.java
[code] package com.cmd.cc.repositories; import org.springframework.data.repository.CrudRepository; import com.cmd.cc.domain.MailingFilter; public interface MailingFilterRepository extends CrudRepository<MailingFilter, Integer>{ } [/code]
6) Implementar Spring Facade service.
Creamos un servicio que será quien interactue con la capa de persistencia.
en src/main/java creamos el package com.cmd.cc.services
y en él creamos primero una interface llamada MailingFilterService.java
[code]
package com.cmd.cc.services;
import com.cmd.cc.domain.MailingFilter;
public interface MailingFilterService {
Iterable<MailingFilter> listAllMailingFilters();
MailingFilter getMailingFilterById(Integer id);
MailingFilter saveMailingFilter(MailingFilter mailingFilter);
void deleteMailingFilter(Integer id);
}
[/code]
en ese mismo package crear la clase que implementa la interface la llamamos MailingFilterServiceImpl.java
[code]
package com.cmd.cc.services;
import org.springframework.beans.factory.annotation.Autowired;
import com.cmd.cc.domain.MailingFilter;
import com.cmd.cc.repositories.MailingFilterRepository;
public class MailingFilterServiceImpl implements MailingFilterService {
private MailingFilterRepository mailingfilterRepository;
@Autowired
public void setMailingFilterRepository(MailingFilterRepository mailingfilterRepository) {
this.mailingfilterRepository = mailingfilterRepository;
}
@Override
public Iterable<MailingFilter> listAllMailingFilters() {
// TODO Auto-generated method stub
return mailingfilterRepository.findAll();
}
@Override
public MailingFilter getMailingFilterById(Integer id) {
// TODO Auto-generated method stub
return mailingfilterRepository.findOne(id);
}
@Override
public MailingFilter saveMailingFilter(MailingFilter mailingFilter) {
// TODO Auto-generated method stub
return mailingfilterRepository.save(mailingFilter);
}
@Override
public void deleteMailingFilter(Integer id) {
// TODO Auto-generated method stub
mailingfilterRepository.delete(id);
}
}
[/code]
