Exception in thread "main" org.hibernate.TypeMismatchException: Provided id of the wrong type

0.0-原本写个test测试myeclipse自动生成的hibernate配置文件,没想到出了以下错误:

Exception in thread "main" org.hibernate.TypeMismatchException: Provided id of the wrong type for class hibernate1.Hibernate1. Expected: class java.lang.Integer, got class java.lang.String
at org.hibernate.event.internal.DefaultLoadEventListener.onLoad(DefaultLoadEventListener.java:132)
at org.hibernate.internal.SessionImpl.fireLoad(SessionImpl.java:1079)
at org.hibernate.internal.SessionImpl.access$2200(SessionImpl.java:172)
at org.hibernate.internal.SessionImpl$IdentifierLoadAccessImpl.load(SessionImpl.java:2425)
at org.hibernate.internal.SessionImpl.get(SessionImpl.java:975)
at test.MainTest.main(MainTest.java:17)

1.0-测试的代码如下:

package test;
import hibernate1.Hibernate1;//数据库表hibernate1的映射
import org.hibernate.Session;
import com.hibernate.test.HibernateSessionFactory;//自动生成的sessionfactory

public class MainTest {

public static void main(String[] args) {
// TODO Auto-generated method stub
Session session = HibernateSessionFactory.getSession();
Hibernate1 biaoHibernate1=(Hibernate1) session.get(Hibernate1.class, "1");
System.out.println(biaoHibernate1.getId());
System.out.println(biaoHibernate1.getUserName());
HibernateSessionFactory.closeSession();
}
}

1.1-Hibernate1.java

public class Hibernate1 implements java.io.Serializable {

// Fields

private Integer id;
private String userName;
private Integer age;

// Constructors

/** default constructor D"hljs-keyword">this.id;
}
...略去get&set方法...
}

1.2-hibernate目录结构图

1.3-数据表hibernate1

2.0-分析原因

Object get(Class clazz,Serializable id)

2.1-解决方法

package test;
import hibernate1.Hibernate1;//数据库表hibernate1的映射
import org.hibernate.Session;
import com.hibernate.test.HibernateSessionFactory;//自动生成的sessionfactory

public class MainTest {

public static void main(String[] args) {
// TODO Auto-generated method stub
Session session = HibernateSessionFactory.getSession();
**Hibernate1 biaoHibernate1=(Hibernate1) session.get(Hibernate1.class, new Integer("1"));**
System.out.println(biaoHibernate1.getId());
System.out.println(biaoHibernate1.getUserName());
HibernateSessionFactory.closeSession();
}

}

3.0-结果输出
