如何映射页面< ObjectEntity>到Page< ObjectDTO>在spring-data-rest中
当我使用 PagingAndSortingRepository.findAll（可分页）点击数据库时，我得到 Page< ObjectEntity> 。但是，我想将DTO暴露给客户端而不是实体。我可以通过将实体注入到它的构造函数中来创建DTO，但是如何将Page对象中的实体映射到DTO？根据spring文档，Page提供了只读操作。
When I hit the database with PagingAndSortingRepository.findAll(Pageable) I get Page<ObjectEntity>. However, I want to expose DTO's to the client and not entities. I can create DTO just by injecting entity into it's constructor, but how do I map the entities in Page object to DTO's? According to spring documentation, Page provides read-only operations.
此外，Page.map不可能，因为我们不支持java 8.如何创建手动映射对象的新页面？
Also, Page.map is not possibility, as we don't have support for java 8. How to create the new Page with mapped objects manually?
您仍然可以使用 Page.map 没有lambda表达式：
You can still use the Page.map without lambda expressions:
Page<ObjectEntity> entities = objectEntityRepository.findAll(pageable);
Page<ObjectDto> dtoPage = entities.map(new Converter<ObjectEntity, ObjectDto>() {
@Override
public ObjectDto convert(ObjectEntity entity) {
ObjectDto dto = new ObjectDto();
// Conversion logic
return dto;
}
});
