想看hibernate官网上注解的配置demo，怎么找啊?报错

想看hibernate官网上注解的配置demo，怎么找啊，下载了hibernate-release-5.2.2.Final.zip，解压后再project下的etc里也没有找到，在哪里找呀，或者直接告我配置是不是错了

这是实体类

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

import org.hibernate.annotations.GenericGenerator;

/**
 * Student entity. @author MyEclipse Persistence Tools
 */
@Entity
@Table(name = "student", catalog = "test")
public class Student implements java.io.Serializable {

	// Fields

	private String tbId;
	private String tbName;
	private Integer tbAge;

	// Constructors

	/** default constructor */
	public Student() {
	}

	/** minimal constructor */
	public Student(String tbId) {
		this.tbId = tbId;
	}

	/** full constructor */
	public Student(String tbId, String tbName, Integer tbAge) {
		this.tbId = tbId;
		this.tbName = tbName;
		this.tbAge = tbAge;
	}

	// Property accessors
	@GenericGenerator(name = "generator", strategy = "increment")
	@Id
	@GeneratedValue(generator = "generator")
	@Column(name = "tb_id", unique = true, nullable = false, length = 22)
	public String getTbId() {
		return this.tbId;
	}

	public void setTbId(String tbId) {
		this.tbId = tbId;
	}

	@Column(name = "tb_name", length = 12)
	public String getTbName() {
		return this.tbName;
	}

	public void setTbName(String tbName) {
		this.tbName = tbName;
	}

	@Column(name = "tb_age")
	public Integer getTbAge() {
		return this.tbAge;
	}

	public void setTbAge(Integer tbAge) {
		this.tbAge = tbAge;
	}

}

下面是配置文件
