[英]Spring Data REST customize POST entity
I'm using Spring Data Rest 3.3.1.我正在使用 Spring 数据 Rest 3.3.1。
I have domain object (this is just an example):我有域 object(这只是一个例子):
@Data @Getter @Setter
@Entity
public class Figure {
@Id private long id;
private int volume;
}
And I have repository for this entity:我有这个实体的存储库:
@RepositoryRestResource
public interface FigureRepository extends CrudRepository<Figure, Long> {}
So, spring automatically creates method for POSTing Figure entity.因此,spring 自动创建 POSTing Figure 实体的方法。 For example:例如:
POST localhost:8080/figures
{
"volume": 1000
}
But I want to pass customized object to POST method and convert it to needed entity, for example但我想将自定义的 object 传递给 POST 方法并将其转换为所需的实体,例如
POST localhost:8080/figures
{
"length": 10,
"width": 10,
"height": 10
}
and example of converter:和转换器的例子:
class FigureDtoConverter implements Converter<FigureDto, Figure> {
@Override
Figure convert(FigureDto dto) {
Figure f = new Figure();
f.setVolume(dto.getLength() * dto.getWidth() * dto.getHeight());
return f;
}
}
How can I do this without creating custom controller?如何在不创建自定义 controller 的情况下做到这一点? Because if I create controller I lost useful spring features like event handling, validating etc因为如果我创建 controller 我失去了有用的 spring 功能,如事件处理、验证等
No way.没门。 You must create your controller.您必须创建 controller。
Use different request mapping path instead of /figures
can keep Spring Data REST endpoints使用不同的请求映射路径而不是/figures
可以保留 Spring 数据 REST 端点
POST localhost:8080/figures
{
"volume": 1000
}
POST localhost:8080/create-figure-by-measurement
{
"length": 10,
"width": 10,
"height": 10
}
Create a POJO containing the fields you want to pass.创建一个包含要传递的字段的 POJO。
public class Edges {
Integer length;
Integer width;
Integer height; //getters and setters
}
You can make a post request with this你可以用这个发出post请求
{
"length": 10,
"width": 10,
"height": 10
}
And get the object of the Edges
in your controller and convert it to Figure
并获取 controller 中Edges
的 object 并将其转换为Figure
@PostMapping("/figure")
public String getEdges(@RequestBody Edges edges){
//...
}
