REST API for Java?
提问by Shiv Kumar Ganesh
I am preparing an application which is console based and the outcome of the application is a RDF/XML file which contains data of all my connections from LinkedIn. Now the problem is that my entire application is console based and I need to have a REST API so as to incorporate with my application.
我正在准备一个基于控制台的应用程序，该应用程序的结果是一个 RDF/XML 文件，其中包含我来自 LinkedIn 的所有连接的数据。现在的问题是我的整个应用程序都是基于控制台的，我需要一个 REST API 以便与我的应用程序合并。
I am not aware of REST API's and how to use it with JAVA but can easily get through the documentation and understand it. My applications use the REST API of LinkedIn.
我不知道 REST API 以及如何将它与 JAVA 一起使用，但可以轻松浏览文档并理解它。我的应用程序使用 LinkedIn 的 REST API。
So can you please suggest some of the good REST API for Java?
那么你能推荐一些适用于 Java 的好的 REST API 吗？

JAX-RSis the standard Java API for RESTful web services. Jerseyis the reference implementation for this, it has server-side as well as client-side APIs (so, ways to expose methods in your code as RESTful web services, as well as ways to talk to RESTful web services running elsewhere).
JAX-RS是用于 RESTful Web 服务的标准 Java API。Jersey是这方面的参考实现，它具有服务器端和客户端 API（因此，可以将代码中的方法公开为 RESTful Web 服务，以及与其他地方运行的 RESTful Web 服务进行通信的方法）。
There are also other implementations of JAX-RS, for example Apache CXFand JBoss RESTEasy.
还有其他 JAX-RS 实现，例如Apache CXF和JBoss RESTEasy。

Quick code example:
快速代码示例：
1) Add the javax.ws.rsdependency in your pom (if using Maven) or download it.
1)在你的 pom 中添加javax.ws.rs依赖项（如果使用 Maven）或下载它。
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>jsr311-api</artifactId>
<version>1.1.1</version>
</dependency>
2) Create an empty class to define the path of your service; for example for hearing at application/service/restwould be
2）创建一个空类来定义你的服务的路径；例如，对于听力application/service/rest将是
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
@ApplicationPath("/service/rest")
public class WebConfig extends Application {
}
3) Create the controller of your api. For example if we need these calls:
application/service/rest/resource/{id}a simple code would be:
3）创建你的api的控制器。例如，如果我们需要这些调用：
application/service/rest/resource/{id}一个简单的代码是：
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.Status;
@Path("resource/{id}")
public class ApiController {
/**
* Call: <code>/service/rest/resource/23</code>
* @return HTTP Response
*/
@GET
public Response getResource(@PathParam("id") String anId) {
Resource myResource = whatever.get(anId);
return Response.status(Status.OK).entity(myResource).build();
}
4) If we want to specify a JSON response be sure you have the getters for your resource and type:
4) 如果我们想指定一个 JSON 响应，请确保您拥有资源的 getter 并键入：
@GET
@Produces("application/json")
public Response getResource(@PathParam("id") String anId) {
// the same
}

If you're considering hosting your Java code in a cloud, Raimme Platform gives you a good opportunity to expose a REST API endpoint with just one annotation.
如果您正在考虑将 Java 代码托管在云中，Raimme Platform 为您提供了一个很好的机会，只需一个注释即可公开 REST API 端点。
Let's say you have a database object/table called my.app.Customer, and you want to create an endpoint for returning all customers that match a certain name. In Raimme, you would achieve this as follows:
假设您有一个名为 的数据库对象/表my.app.Customer，并且您想要创建一个端点来返回与某个名称匹配的所有客户。在 Raimme 中，您可以按如下方式实现：
@Rest(url = "customers/find")
public List<Customer> find(@Param("keyword") String keyword)
{
return { select id, name, company.name from my.app.Customer where name ilike '%#keyword%' };
}
