Question

我有一个struts2 + spring + hibernate + maven + mysql应用程序。所以，当我插入一个对象时，我得到了：

17.09.2015 15:41:41 *WARN * JDBCExceptionReporter: SQL Error: 0, SQLState: 07001
17.09.2015 15:41:41 *ERROR* JDBCExceptionReporter: No value specified for parameter 5
org.springframework.dao.InvalidDataAccessResourceUsageException: could not insert: [com.proximate.dashmate.models.DescargasTienda]; SQL [insert into descargas_tienda (market, descargas, actualizaciones, fecha_actualizacion, id) values (?, ?, ?, ?, ?)]; nested exception is org.hibernate.exception.SQLGrammarException: could not insert: [com.proximate.dashmate.models.DescargasTienda]
    at org.springframework.orm.hibernate3.SessionFactoryUtils.convertHibernateAccessException(SessionFactoryUtils.java:629)

当我这样做时：

@Override
public void insert(DescargasTienda o) {
    // TODO Auto-generated method stub
    getHibernateTemplate().save(o);
}

这是我的hibernate.cfg.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.show_sql">false</property>
        <property name="hibernate.hbm2ddl.auto">update</property>
        <mapping resource="mappings/dashmate/DescargasTienda.hbm.xml" />
    </session-factory>
</hibernate-configuration>

这是我的映射：

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!-- Generated 6/01/2011 05:14:47 PM by Hibernate Tools 3.2.4.GA -->
<hibernate-mapping>
    <class name="com.proximate.dashmate.models.DescargasTienda" table="descargas_tienda">
        <id name="id" type="integer">
            <column name="id"  />
            <generator class="native" />
        </id>
        <property name="market" type="string">

        </property>
        <property name="actualizaciones" type="integer">
            <column name="actualizaciones" />
        </property>
        <property name="fecha" type="java.sql.Timestamp">
            <column name="fecha_actualizacion" default="CURRENT_TIMESTAMP"/>
        </property>
    </class>    
</hibernate-mapping>

最后这是我的春天背景：

我已经尝试将我的密钥生成器从本机更改为增量，并使用完全相同的结果进行标识。那么我做错了什么？，为什么hibernate在插入过程中没有填充我的主键，如hbm中所述？

提前致谢。

为什么hibernate主键生成器无法正常工作？
