请看下,谢谢

表user      create table `xzw`.`user`(
        `id` int not null auto_increment,
       `name` varchar(45) default '' not null,
        primary key (`id`)
    );里面有(1,'a')数据

user.hfg.xml文件<?xml version="1.0"?>

    <class name="aa.User" table="user" catalog="xzw">
        <id name="id" type="integer">
            <column name="id" />
            <generator class="increment"></generator>
        </id>
        <property name="name" type="string">
            <column name="name" length="45" not-null="true" />
        </property>
    </class>
</hibernate-mapping>

我用User user=(User)session.load(User.class,new Integer(1));为什么会提示我could not load an entity: [aa.User#1]
