我正在使用spring Boot 3和java 17构建一个web API。我正在使用lombok和mapstruct，但我遇到了这个错误：

19:48
C:\Users\xxxxx\Documents\workspace\eshop\src\main\java\com\eshop\mapper\ProductMapper.java:19:48
java: No property named "product.name" exists in source parameter(s). Did you mean "null"?
C:\Users\xxxxx\Documents\workspace\eshop\src\main\java\com\eshop\mapper\ProductMapper.java:20:55
java: No property named "product.description" exists in source parameter(s). Did you mean "null"?
C:\Users\xxxxx\Documents\workspace\eshop\src\main\java\com\eshop\mapper\ProductMapper.java:21:53
java: No property named "product.id" exists in source parameter(s). Did you mean "null"?

这是我的mapper：

package com.eshop.mapper;

import com.eshop.domain.entity.Product;
import com.eshop.domain.entity.ProductVariant;
import com.eshop.dto.request.body.ProductCreationBody;
import com.eshop.dto.request.response.ProductGetDetailsResponse;
import org.mapstruct.Mapper;
import org.mapstruct.Mapping;
import org.mapstruct.Mappings;

import java.util.List;

@Mapper(componentModel = "spring")
public interface ProductMapper {

    ProductGetDetailsResponse map(Product product);

    @Mappings({
            @Mapping(target = "name", source = "product.name"),
            @Mapping(target = "description", source = "product.description"),
            @Mapping(target = "productId", source = "product.id"),
    })
    ProductGetDetailsResponse map(ProductVariant productVariant);

    Product map(ProductCreationBody productCreationRequestBody);

    List<ProductGetDetailsResponse> map(List<ProductVariant> products);


}

这是我试图绘制的物体

package com.eshop.dto.request.response;

import lombok.*;

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@ToString
public class ProductGetDetailsResponse {

    private Long id;

    private Long productId;

    private String name;

    private String description;

    private String imageUrl;

    private String color;

    private String size;

    private String price;

    private String discount;

    private String displayOrder;
}

package com.eshop.domain.entity;

import com.eshop.domain.enums.ProductGender;
import jakarta.persistence.*;
import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;

import java.io.Serializable;
import java.time.LocalDate;

@Entity
@Table(name = "product_variant", uniqueConstraints = {
        @UniqueConstraint(columnNames = {"product_id", "productColor", "productSize"})
})
@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
public class ProductVariant implements Serializable {

    private static final Long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Enumerated(EnumType.STRING)
    private ProductGender productGender;

    private String productColor;

    private String productSize;

    private Integer unitsInStock;

    private String imageUrl;

    private Double price;

    private Integer discount;

    private LocalDate discountStartDate;

    private LocalDate discountEndDate;

    private Integer displayOrder;

    @ManyToOne
    @JoinColumn(name = "product_id")
    private Product product;

}

package com.eshop.domain.entity;

import com.eshop.domain.enums.ProductStatus;
import jakarta.persistence.*;
import lombok.*;
import org.hibernate.annotations.CreationTimestamp;
import org.hibernate.annotations.UpdateTimestamp;

import java.io.Serializable;
import java.util.Date;
import java.util.Set;

@Table(name = "products", uniqueConstraints = {
        @UniqueConstraint(columnNames = "name")
})
@Entity
@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@ToString
public class Product implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(unique = true)
    private String name;

    private String description;

    @Enumerated(EnumType.STRING)
    private ProductStatus status;

    @ManyToOne
    @JoinColumn(name = "store_id")
    private Store store;

    @CreationTimestamp
    @Column(name = "created_at")
    private Date createdAt;

    @UpdateTimestamp
    @Column(name = "updated_at")
    private Date updatedAt;

    @OneToMany(mappedBy = "product", fetch = FetchType.LAZY, cascade = CascadeType.ALL, orphanRemoval = true)
    private Set<ProductVariant> productVariants;

    @ManyToOne
    @JoinColumn(name = "subCategory_id")
    private SubCategory subCategory;
}

这是我的Pom.xml

我试图以各种可能的方式将依赖项和插件放入pom.xml中（lombok优先，mapstruct优先，lombok-mapstruct-processor），我试图降级到旧版本的lombok和mapstruct，但它不起作用。
我有错误，然后突然它的工作，然后我添加一个字段到我的Dto和它再次崩溃，但我不能找出是什么使它以前的工作。
当我运行这个应用程序的时候，问题就出现了。清洁安装工作正常，我从lombok和mapstruct中生成了正确的类，所以我真的不明白这里发生了什么。
