Best way to return 2 objects inside a response body in Spring
问题
我想将2个对象（两个不同类的实例）放在POST请求的主体中，处理这些信息，然后将更新后的对象发送回响应。最佳方法是什么？我知道可以将这些对象放入映射中或创建一个包装对象，但可能有更加优雅的方式来实现这一点。
请求主体的示例：
{
"object1": {
"data1": "val1",
"data2": "val2"
},
"object2": {
"dataN": "valN"
}
}
响应主体的示例：
{
"object1": {
"data1": "updatedVal1",
"data2": "val2"
},
"object2": {
"dataN": "updatedValN"
}
}
英文:
I want to send 2 objects (instances of 2 different classes) inside POST request body, process the information and the send back the updated objects in response. What is the best way of doing that ? I know I can put the objects in a map or create a wrapper object, but probably there is a more graceful way of achieving that.
Example of a request body:
{
"object1": {
"data1": "val1",
"data2": "val2"
},
"object2": {
"dataN": "valN"
}
}
Example of a response body:
{
"object1": {
"data1": "updatedVal1",
"data2": "val2"
},
"object2": {
"dataN": "updatedValN"
}
}

不，没有一种优雅的方式可以发送两个Java对象。使用一个POJO已经足够优雅了。拥有多个表示特定事物的POJO没有问题。与使用Map相比，使用POJO是更好的实践，因为它提供了类型安全性。如果您使用lombok库，可以消除所有样板代码，使您的POJO变得简洁：
@Data
public class TwoResponse {
private OneType object1;
private TwoType object2;
}
英文:
No, there is no graceful way of sending two java objects. Using a POJO is graceful enough. There's nothing wrong with having many POJOs that represent specific things. Using POJOs is a better practice than using a Map since it provides type safety. And if you use the lombok library you can eliminate all the boilerplate code so your POJO is nice and small:
@Data
public class TwoResponse {
private OneType object1;
private TwoType object2;
}
