从@PathParam获取对象 [英] Getting object from @PathParam

问题描述

我正在创建用于访问数据的RESTful服务.

I'm creating a RESTful service for accessing data.

所以我开始编写该服务，首先我用以下代码创建了ReadOnlyResource接口:

So I started writing that service, first I created a ReadOnlyResource interface with the following code:

public interface ReadOnlyResource<E, K> {
    Collection<E> getAll();
    E getById(K id);
}

其中E是返回的类型，K是关键元素.

Where E is the returned type and K is the key element.

因此，如果我要使用<Integer, Integer>实施，我将像t一样注入密钥

So if I'm implementing with <Integer, Integer> I'll inject the key like t

@GET
@Path("/{id}")
@Override
public Integer getById(@PathParam("id") Integer id) {
    return null;
}

但是当我的钥匙比较复杂时，就像这样:

But when my key is more complex, like this:

public class ComplexKey {
    private String name;
    private int value;
}

如何注入它以便可以使用我的界面?

How can I inject this so I can use my interface?

是否可以同时注入两个参数并使用它们创建密钥?

Is there a way to inject both params and create the key with them?

@QueryParam的解决方案无济于事，因为我尝试访问的是/一些名字/一些数字，并接收一个包含以下内容的ComplexKey实例:网址中的一些名称和一些数字值.

the solution of @QueryParam doesn't help because what I try to reach is going to /some name/some number and receive a ComplexKey instance which contains the some name and some number values from the url.

推荐答案

我尝试到达的位置是/一些名称/一些数字，并接收一个ComplexKey实例，该实例包含来自url的一些名称和一些数字值

what I try to reach is going to /some name/some number and receive a ComplexKey instance which contains the some name and some number values from the url

使用 @BeanParam

public class ComplexKey {
    @PathParam("name")
    private String name;
    @PathParam("value")
    private int value;
    // getters/setters
}

@Path("/{name}/{value}")
getById(@BeanParam ComplexKey key)
