java - Hibernate OneToMany 关系错误

Question

我是 Hibernate 新手。当我尝试在两个类之间建立一对多关系时，我失败了。

它给出了一个错误:

Exception in thread "main" java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z
    at org.hibernate.cfg.AnnotationBinder.processElementAnnotations(AnnotationBinder.java:1912)
    at org.hibernate.cfg.AnnotationBinder.processIdPropertiesIfNotAlready(AnnotationBinder.java:796)
    at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:707)

    at org.hibernate.tool.hbm2ddl.SchemaExport.<init>(SchemaExport.java:92)
    at org.hibernate.business.TestBusiness.main(TestBusiness.java:14)

我的定义:

名片.java

@OneToMany(targetEntity=BusinessPhone.class, mappedBy="card",
        cascade=CascadeType.ALL, fetch=FetchType.EAGER)
public List<BusinessPhone> getPhones() {
    return phones;
}

商务电话.java

@ManyToOne
@JoinColumn(name="business_id")
public BusinessCard getCard() {
    return card;
}
public void setCard(BusinessCard card) {
    this.card = card;
}

请帮我看看错误的根源是什么？

您的类路径中可能有两个 jar 包定义了相同的 OneToMany 注释，但版本不同(一个具有 orphanRemoval 属性，另一个没有该属性)。修复你的类路径。
