我从这个来源下载了应用程序https://github.com/springframeworkguru/spring5-mvc-rest/tree/vendor-api 而且我的MapStruct有问题。
@Mapper
public interface CategoryMapper {
CategoryMapper INSTANCE = Mappers.getMapper(CategoryMapper.class);
CategoryDTO categoryToCategoryDTO(Category category);
}
@Data
public class CategoryDTO {
private Long id;
private String name;
}
域类：
@Data
@Entity
public class Category {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
}
服务等级：
@Service
public class CategoryServiceImpl implements CategoryService {
private final CategoryMapper categoryMapper;
private final CategoryRepository categoryRepository;
public CategoryServiceImpl(CategoryMapper categoryMapper, CategoryRepository categoryRepository) {
this.categoryMapper = categoryMapper;
this.categoryRepository = categoryRepository;
}
}
在pom.xml依赖项中，我仅粘贴了两个：
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> …
