Hibernate可能的Maven依赖冲突
Hibernate possible Maven dependency conflict
我是 Spring 3 和 Hibernate 3 的新手，我正在尝试构建一个简单的应用程序来学习。但是，如果我尝试执行它会抛出异常。
据我所知可能与maven依赖冲突有关，但我不知道如何解决。
这是完整的轨迹：

我的数据库将有一个名为 Usuario 的 table，所以这里是相关的 classes:
Usuario 模型class:
es.sancas.prueba.bean.Usuario.java:
package es.sancas.prueba.bean;
import java.io.Serializable;
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="usuario")
public class Usuario implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
private long id;
@Column(name = "nombre")
private String nombre;
public Usuario(String nombre) {
super();
this.nombre = nombre;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getNombre() {
return nombre;
}
public void setNombre(String nombre) {
this.nombre = nombre;
}
}
我的 DAO 接口：
es.sancas.prueba.dao.IUsuarioDAO.java:
package es.sancas.prueba.dao;
import es.sancas.prueba.bean.Usuario;
public interface IUsuarioDAO {
Usuario getUsuario(int id);
int save(Usuario usuario);
void update(Usuario usuario);
void view(Usuario usuario);
void delete(int id);
}
它的实现：
es.sancas.prueba.dao.UsuarioDAO.java:
package es.sancas.prueba.dao;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import es.sancas.prueba.bean.Usuario;
@Repository
@Transactional
public class UsuarioDAO implements IUsuarioDAO {
@Autowired
private SessionFactory sessionFactory;
@Override
public Usuario getUsuario(int id) {
return (Usuario) sessionFactory.getCurrentSession().get(Usuario.class, id);
}
@Override
public int save(Usuario usuario) {
return (Integer) sessionFactory.getCurrentSession().save(usuario);
}
@Override
public void update(Usuario usuario) {
sessionFactory.getCurrentSession().merge(usuario);
}
@Override
public void view(Usuario usuario) {
sessionFactory.getCurrentSession().merge(usuario);
}
@Override
public void delete(int id) {
Usuario usuario = getUsuario(id);
sessionFactory.getCurrentSession().delete(usuario);
}
}
如果我缺少要显示的信息，请告诉我。谢谢！
P.S：我认为如果我 post 我的 mvn dependency:tree -Dverbose
可能会有用

终于找到了解决方案，但可能并不适合所有人。
经过多次尝试，我得出结论，弱点是我的 app-context.xml 中的 session factory bean，并尝试改用 Hibernate 4（并使用最新的Spring 3.x.x 发布）。它奏效了！
更改如下：
app-context.xml
<!-- ... -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager"
p:sessionFactory-ref="sessionFactory" />
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<!-- ... -->
</bean>
<!-- ... -->

<!-- ... -->

我是 Spring 3 和 Hibernate 3 的新手，我正在尝试构建一个简单的应用程序来学习。但是，如果我尝试执行它会抛出异常。
据我所知可能与maven依赖冲突有关，但我不知道如何解决。
这是完整的轨迹：

我的数据库将有一个名为 Usuario 的 table，所以这里是相关的 classes:
Usuario 模型class:
es.sancas.prueba.bean.Usuario.java:
package es.sancas.prueba.bean;
import java.io.Serializable;
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="usuario")
public class Usuario implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
private long id;
@Column(name = "nombre")
private String nombre;
public Usuario(String nombre) {
super();
this.nombre = nombre;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getNombre() {
return nombre;
}
public void setNombre(String nombre) {
this.nombre = nombre;
}
}
我的 DAO 接口：
es.sancas.prueba.dao.IUsuarioDAO.java:
package es.sancas.prueba.dao;
import es.sancas.prueba.bean.Usuario;
public interface IUsuarioDAO {
Usuario getUsuario(int id);
int save(Usuario usuario);
void update(Usuario usuario);
void view(Usuario usuario);
void delete(int id);
}
它的实现：
es.sancas.prueba.dao.UsuarioDAO.java:
package es.sancas.prueba.dao;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import es.sancas.prueba.bean.Usuario;
@Repository
@Transactional
public class UsuarioDAO implements IUsuarioDAO {
@Autowired
private SessionFactory sessionFactory;
@Override
public Usuario getUsuario(int id) {
return (Usuario) sessionFactory.getCurrentSession().get(Usuario.class, id);
}
@Override
public int save(Usuario usuario) {
return (Integer) sessionFactory.getCurrentSession().save(usuario);
}
@Override
public void update(Usuario usuario) {
sessionFactory.getCurrentSession().merge(usuario);
}
@Override
public void view(Usuario usuario) {
sessionFactory.getCurrentSession().merge(usuario);
}
@Override
public void delete(int id) {
Usuario usuario = getUsuario(id);
sessionFactory.getCurrentSession().delete(usuario);
}
}
如果我缺少要显示的信息，请告诉我。谢谢！
P.S：我认为如果我 post 我的 mvn dependency:tree -Dverbose
可能会有用[INFO] Scanning for projects...

终于找到了解决方案，但可能并不适合所有人。
经过多次尝试，我得出结论，弱点是我的 app-context.xml 中的 session factory bean，并尝试改用 Hibernate 4（并使用最新的Spring 3.x.x 发布）。它奏效了！
更改如下：
app-context.xml
<!-- ... -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager"
p:sessionFactory-ref="sessionFactory" />
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<!-- ... -->
</bean>
<!-- ... -->
pom.xml:
<!-- ... -->
<java-version>1.7</java-version>
<org.springframework-version>3.2.13.RELEASE</org.springframework-version>
<!-- ... -->
