Acabo de crear este ejemplo para ti:

Entidad de datos: com.demo.data.User

package com.demo.data; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table(name = "SYS_USERS") public class User { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "USER_ID") private int id; @Column(name = "USER_NAME") private String name; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } }

Repositorio JPA de Spring Data: com.demo.data.UserRepository

package com.demo.data; import org.springframework.data.repository.CrudRepository; public interface UserRepository extends CrudRepository<User, Integer> { }

Servicio

Interfaz:

package com.demo.svc; import com.demo.data.User; public interface UserService { User findUserById(Integer id); }

Implementación:

package com.demo.svc; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.demo.data.User; import com.demo.data.UserRepository; @Service public class UserServiceImpl implements UserService { @Autowired UserRepository userRepository; public User findUserById(Integer id) { return userRepository.findOne(id); } }

Controlador web: com.demo.web.UserController

package com.demo.web; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import com.demo.svc.UserService; @Controller public class UserController { @Autowired UserService svc; @RequestMapping("/") @ResponseBody public String test() { return svc.findUserById(1).getName(); } }

Spring Boot no funciona con Google App Engine (al menos no para mí).

Sin embargo, muchos de los ejemplos escritos o disponibles en GitHub u otros repositorios usan Spring Boot, ¿hay algún ejemplo para Spring-Data-JPA que no use Spring Boot y use XML de contexto simple como antes?

Eso mostrará

- spring / context.xml (o servlet-context.xml)
