spring3.2+hibernate4 注解配置报错：No identifier specified for entity: com.jialin.entity.SysDefinitionField。
BAIDU，GOOGLE一天了，也没有解决。求救啊！

entity类如下：



package com.jialin.entity;



import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.GenerationType;

import javax.persistence.Id;

import javax.persistence.Table;



@Entity

@Table(name = "sys_definition_table")

public class SysDefinitionTable {

	private int id;

	private String name;

	private String dbname;



	@Column(name="name", length=30, nullable=false, unique=true)

	public String getName() {

		return name;

	}



	public void setName(String name) {

		this.name = name;

	}

	

	@Column(name="dbname", length=20, nullable=false, unique=true)

	public String getDbname() {

		return dbname;

	}



	public void setDbname(String dbname) {

		this.dbname = dbname;

	}





	@Id

	@Column(name="id")

	@GeneratedValue(strategy=GenerationType.IDENTITY)

	public int getId() {

		return id;

	}



	public void setId(int id) {

		this.id = id;

	}

}

spring配置如下：applicationContext-common.xml
