AnnotationException: Cannot find the expected secondary table

今天遇到一个比较奇怪的问题就是表明明就存在，却总是抛出异常说表不存在，其异常代码如下：

Caused by: org.hibernate.AnnotationException: Cannot find the expected secondary table: no bio_experiment_protocol available for com.founder.cims.bio.model.Protocol

在项目中我用的一对多的双向关联，并且用的是中间表来进行两个表关联的。其关联关系如下：

@Entity
@Table(name = "BIO_NOTEBOOK")
@SequenceGenerator(name = "BIO_NOTEBOOK_SQ", sequenceName = "BIO_NOTEBOOK_SQ",
		allocationSize = 1, initialValue = 1)
public class Notebook implements Serializable{
	
	private static final long serialVersionUID = 7346303079987267177L;
	
	private Integer id;
	private String name;
	private String description;
	private int staus;
	private String author;
	
	
	private Experiment experiment;

        @ManyToOne(fetch = FetchType.LAZY, targetEntity = Experiment.class)
	@JoinTable(name = "BIO_EXPERIMENT_NOTEBOOK",
			joinColumns = {@JoinColumn(name = "NOTEBOOK_ID")},
			inverseJoinColumns = {@JoinColumn(name = "EXPERIMENT_ID")}
			)
        public Experiment getExperiment() {
		return experiment;
	}

	public void setExperiment(Experiment experiment) {
		this.experiment = experiment;
	}

一对多的那端

@Entity
@Table(name = "BIO_EXPERIMENT")
@SequenceGenerator(name = "BIO_EXPERIMENT_SQ", sequenceName = "BIO_EXPERIMENT_SQ", allocationSize = 1, initialValue = 1)
public class Experiment implements Serializable{
	
	private static final long serialVersionUID = 1315584437277200383L;
	
	private Integer id;
	private Study study;
	private String type;
	private Integer status;
	private InVivoExperiment invivoExperiment;
	private InVitroExperiment invitroExperiment;
	private DmpkExperiment dmpkExperiment;
	
	private Set<Notebook> notebooks;

        @OneToMany(mappedBy = "experiment")
	public Set<Notebook> getNotebooks() {
		return notebooks;
	}

	public void setNotebooks(Set<Notebook> notebooks) {
		this.notebooks = notebooks;
	}

当我把注解写到变量声明的上面就正确了即：

@Entity
@Table(name = "BIO_NOTEBOOK")
@SequenceGenerator(name = "BIO_NOTEBOOK_SQ", sequenceName = "BIO_NOTEBOOK_SQ",
		allocationSize = 1, initialValue = 1)
public class Notebook implements Serializable{
	
	private static final long serialVersionUID = 7346303079987267177L;
	
	private Integer id;
	private String name;
	private String description;
	private int staus;
	private String author;
	
	@ManyToOne(fetch = FetchType.LAZY, targetEntity = Experiment.class)
	@JoinTable(name = "BIO_EXPERIMENT_NOTEBOOK",
			joinColumns = {@JoinColumn(name = "NOTEBOOK_ID")},
			inverseJoinColumns = {@JoinColumn(name = "EXPERIMENT_ID")}
			)
	private Experiment experiment;

        public Experiment getExperiment() {
		return experiment;
	}

	public void setExperiment(Experiment experiment) {
		this.experiment = experiment;
	}

目前我也不知道是什么原因，有哪位知道的话可以给留言呀，期待中，谢谢！
