[英]Is it possible to have strongly typed HTTP request handlers in Restlet?
Consider the following ServerResource
derived type: 考虑以下
ServerResource
派生类型:
public class UserResource extends ServerResource {
@Get
public User getUser(int id) {
return new User(id, "Mark", "Kharitonov");
}
}
(Yes, it always returns the same user no matter the given id). (是的,无论给定的id总是返回相同的用户)。
Is it possible to make it work in Restlet? 是否可以使其在Restlet中工作? Because, as far as I understand, the expected signature of the GET handler is:
因为据我了解,GET处理程序的预期签名是:
Representation get();
OR 要么
Representation get(Variant v); // (no idea what it means yet)
Now I understand, that I can implement the non type safe GET handler to extract the arguments from the request and then invoke getUser
, after which to compose the respective Representation
instance from the result and return. 现在我明白了,我可以实现非类型安全的GET处理程序以从请求中提取参数,然后调用
getUser
,然后从结果中组成相应的Representation
实例并返回。 But this is a boilerplate code, it does not belong with the application code, its place is inside the framework. 但这是一个样板代码,它不属于应用程序代码,它位于框架内部。 At least, this is how it is done by OpenRasta - the REST framework I have been using in .NET
至少,这是通过OpenRasta(我在.NET中一直在使用的REST框架)完成的
Thanks. 谢谢。
You should remove the parameter from the signature 您应该从签名中删除参数
@Get
public User getUser() {
String id = getQuery().getFirstValue("id");
return new User(id, "Mark", "Kharitonov");
}
No need to override the get() methods in this case as the @Get annotation will be automatically detected. 在这种情况下,无需重写get()方法,因为将自动检测@Get批注。
