如何在Java中使用REST [英] How to consume REST in Java

问题描述

使用Java工具，

wscompile for RPC
wsimport for Document
etc..

我可以使用WSDL生成访问SOAP Web服务所需的存根和类。

I can use WSDL to generate the stub and Classes required to hit the SOAP Web Service.

但我不知道如何在REST中做同样的事情。
如何获得访问REST Web服务所需的Java类。
无论如何，点击这项服务的方法是什么？

But I have no idea how I can do the same in REST. How can I get the Java classes required for hitting the REST Web Service. What is the way to hit the service anyway?

有人能指路吗？

推荐答案

您可以使用 HttpURLConnection 。
下面是使用Java SE API（包括JAXB）调用RESTful服务的示例：

You can use HttpURLConnection. Below is an example of calling a RESTful service using the Java SE APIs including JAXB:

String uri =
    "http://localhost:8080/CustomerService/rest/customers/1";
URL url = new URL(uri);
HttpURLConnection connection =
    (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setRequestProperty("Accept", "application/xml");

JAXBContext jc = JAXBContext.newInstance(Customer.class);
InputStream xml = connection.getInputStream();
Customer customer =
    (Customer) jc.createUnmarshaller().unmarshal(xml);

connection.disconnect();
