Question

我使用Spring和Hibernet开发Java webapp。

我想声明外键，所以我需要使用INNODB引擎。我已经在datasource.XML上声明了它，但是这个表是由Hibernate使用MYSAM引擎自动创建的。

这是我的实体：

package com.atlantis.atecliente.model;

import java.util.List;

导入javax.persistence。*;

@Entity
@Table(name="Expediente")
public class Expediente {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int codigo;

@ManyToOne
@JoinColumn(name = "tipoExpediente")
private TipoExpediente tipoExpediente;

@Column(length = 30)
private String estado;

public int getCodigo() {
    return codigo;
}

public void setCodigo(int codigo) {
    this.codigo = codigo;
}

public TipoExpediente getTipoExpediente() {
    return tipoExpediente;
}

public void setTipoExpediente(TipoExpediente tipoExpediente) {
    this.tipoExpediente = tipoExpediente;
}

public String getEstado() {
    return estado;
}

public void setEstado(String estado) {
    this.estado = estado;
}

}

这里是datasource.XML：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <property name="url" value="jdbc:mysql://SBPORTALPRE/atclientepre" />
    <property name="username" value="********" />
    <property name="password" value="********" />
</bean>

<bean id="sessionFactory"     class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="packagesToScan">
        <list>
            <value>com.atlantis.atecliente.model</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
    </property>
</bean>

<tx:annotation-driven transaction-manager="transactionManager"/>
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

</beans>

请帮忙吗？

Answer 1

错误发生在

<prop key="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>

正确的行是：

<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>

由于

Hibernate不要使用方言INNODB
