public class Release {

    @Id
    @GeneratedValue
    @Column(name="id")
    protected int getReleaseIndex() {

    protected void setReleaseIndex(int releaseIndex) {

    public void setReleaseName(String releaseName) {
        this.releaseName = releaseName;
    }
    @OneToMany(mappedBy="release")
    public Set<ProductInfo> getProductInfo() {
        return ProductInfo;
    }
    public void setProductInfo(Set<ProductInfo> productInfo) {
        this.productInfo = productInfo;
    }
}

以上是我想创建 ManytoOne 关系的两个类，但它给了我错误无法确定类型：dao.Release，在表：product_info，对于列：[org.hibernate.mapping.Column(release)]

您会遇到此错误，因为注释有时在字段中有时在方法中不一致。如果您不想使用 AccessType，最简单的解决方案是将注释从 release-field 移动到 getRelease 方法。
