Java 休眠父-子相同表错误

java mysql spring hibernate

Java 休眠父-子相同表错误,java,mysql,spring,hibernate,Java,Mysql,Spring,Hibernate,我对Hibernate在同一个表中使用父子关系有问题。我可以选择和插入，但不能删除。我写了一个JUnit测试来看看发生了什么，发现了一些奇怪的行为以下是我如何定义我的表： CREATE TABLE `product` ( `productId` bigint(20) NOT NULL AUTO_INCREMENT, `name` varchar(50) NOT NULL, `parentProductId` bigint(20) NULL DEFAULT NULL, PRIMA

我对Hibernate在同一个表中使用父子关系有问题。我可以选择和插入，但不能删除。我写了一个JUnit测试来看看发生了什么，发现了一些奇怪的行为

以下是我如何定义我的表：

CREATE TABLE `product` (
  `productId` bigint(20) NOT NULL AUTO_INCREMENT,
  `name` varchar(50) NOT NULL,
  `parentProductId` bigint(20) NULL DEFAULT NULL,
  PRIMARY KEY (`productId`),
  CONSTRAINT `FK_PARENTPRODUCT` FOREIGN KEY (`parentProductId`) REFERENCES `product` (`productId`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=latin1;

我的产品类看起来是：

@Entity
@Table(name = "product")
public class Product {

    private Long productId;
    private String name;
    private Product parentProduct;
    private Set<Product> children;
    private List<CustomerProduct> productCustomers;

    public Product() {
    }

    public Product(Long productId, String name) {
        this.productId = productId;
        this.name = name;
    }

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    public Long getProductId() {
        return productId;
    }

    public void setProductId(Long productId) {
        this.productId = productId;
    }

    @NotNull
    @Size(min = 1, max = 50)
    public String getName() {
    return name;
    }

    public void setName(String name) {
    this.name = name;
    }

    @ManyToOne
    @JoinColumn(name = "parentProductId")
    public Product getParentProduct() {
        return parentProduct;
    }

    public void setParentProduct(Product parentProduct) {
        this.parentProduct = parentProduct;
    }

    @OneToMany(mappedBy = "parentProduct", fetch = FetchType.EAGER)
    public Set<Product> getChildren() {
        return children;
    }

    public void setChildren(Set<Product> children) {
        this.children = children;
    }

    @OneToMany(mappedBy = "product")
    public List<CustomerProduct> getProductCustomers() {
        return productCustomers;
    }

    public void setProductCustomers(List<CustomerProduct> productCustomers) {
        this.productCustomers = productCustomers;
    }

    @Override
    public boolean equals(Object obj) {
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        final Product other = (Product) obj;
        if (this.productId != other.productId
            && (this.productId == null || !this.productId.equals(other.productId)))
                return false;
        if ((this.name == null) ? (other.name != null) : !this.name.equals(other.name))
            return false;
        return true;
    }

    @Override
    public int hashCode() {
        int hash = 7;
        hash = 31 * hash + name.length();
        hash = 31 * hash + (name == null ? 0 : name.hashCode());
        return hash;
    }

    @Override
    public String toString() {
        return "Product [productId=" + productId + ", name=" + name + "]";
    }
}

前两次测试通过。第三个总是失败，在hashcode方法的第二行出现NullPointerException。表示名称为空。我验证了只有在设置了parentProductId时才会发生这种情况。我不明白为什么会这样。名称不应为空。我为类定义hibernate注释的方式是否有错误

这是我的stacktrace，如果有人感兴趣
