我在spring boot中有rest api：
以下是我的“产品”类代码：

import org.springframework.data.annotation.CreatedBy;
    import org.springframework.data.annotation.CreatedDate;
    import org.springframework.data.annotation.LastModifiedBy; 
    import org.springframework.data.annotation.LastModifiedDate;
    import org.springframework.format.annotation.DateTimeFormat;

    import javax.persistence.*;
    import java.time.LocalDateTime;
    import java.util.List;
    import java.util.ArrayList;

    @Table
    @Entity
    public class Product{
        @Id @GeneratedValue
        @CreatedBy @LastModifiedBy
        private Long id;
        private String name;
        @OneToMany                                <--- in this line I tried having it as @OneToMany(cascade = {CascadeType.ALL}), I also tried MERGE, PERSIST, but none worked.
        @JoinColumn
        private List<Component> productComponents = new ArrayList<>();
        private Double quantity = 0.0;
        private Double productCost = 0.0;
        private Double productPrice = 0.0;
        @DateTimeFormat(pattern = "mm/dd/yyyy hh:mm:ss")
        @CreatedDate @LastModifiedDate
        private LocalDateTime createdAt;
        private String status;  

        public Product(){

        }

        public Product(Long id, String name, List<Component> productComponents, Double quantity, Double productCost, Double productPrice, LocalDateTime createdAt, String status){
            this.id = id;
            this.name = name;
            this.productComponents = productComponents;
            this.quantity = quantity;
            this.productCost = productCost;
            this.productPrice = productPrice;
            this.createdAt = createdAt;
            this.status = status;
        }

        //getters
        public Long getId(){
            return this.id;
        }

        public String getName(){
            return this.name;
        }

        public List<Component> getProductComponents(){
            return this.productComponents;
        }

        public Double getQuantity(){
            return this.quantity;
        }

        public Double getProductCost(){
            return this.productCost;
        }

        public Double getProductPrice(){
            return this.productPrice;
        }

        public LocalDateTime getCreatedAt(){
            return this.createdAt;
        }

        public String getStatus(){
            return this.status;
        }

        //setters
        public void setId(Long id){
            this.id = id;
        }

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

        public void setProductComponents(List<Component> productComponents){
            this.productComponents = productComponents;
        }

        public void addProductComponents(Component myComponent){
            this.productComponents.add(myComponent);
        }

        public void removeProductComponent(Component myComponent){
            this.productComponents.remove(myComponent);
        }

        public void setProductCost(Double productCost){
            this.productCost = productCost;
        }

        public void setProductPrice(Double productPrice){
            this.productPrice = productPrice;
        }

        public void setQuantity(Double quantity){
            this.quantity = quantity;
        }

        public void setCreatedAt(LocalDateTime createdAt){
            this.createdAt = createdAt;
        }

        public void setStatus(String status){
            this.status = status;
        }

        //toString method
}

我的api在我第一次发出post请求时起作用，然后每次尝试发出post请求时都会出现以下错误：

Hibernate: select next_val as id_val from hibernate_sequence for update
Hibernate: update hibernate_sequence set next_val= ? where next_val=?
Hibernate: select next_val as id_val from hibernate_sequence for update

这种问题背后的原因可能是什么？
在这一行中，它说@onetoone，我尝试将它作为@onetomany（cascade={cascadetype.all}），我也尝试了merge，persist，但都不起作用。

Javaspringspring-bootspring-data-jpa
