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

问题描述

使用 Java 工具，

Using Java tools,

wscompile for RPC
wsimport for Document
etc..

我可以使用 WSDL 生成命中 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.如何获取访问 REST Web 服务所需的 Java 类.无论如何打服务的方法是什么?

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?

谁能给我指路?

推荐答案

工作示例，试试这个:

package restclient;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class NetClientGet {
    public static void main(String[] args) {
        try {

            URL url = new URL("http://localhost:3002/RestWebserviceDemo/rest/json/product/dynamicData?size=5");//your url i.e fetch data from .
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");
            conn.setRequestProperty("Accept", "application/json");
            if (conn.getResponseCode() != 200) {
                throw new RuntimeException("Failed : HTTP Error code : "
                        + conn.getResponseCode());
            }
            InputStreamReader in = new InputStreamReader(conn.getInputStream());
            BufferedReader br = new BufferedReader(in);
            String output;
            while ((output = br.readLine()) != null) {
                System.out.println(output);
            }
            conn.disconnect();

        } catch (Exception e) {
            System.out.println("Exception in NetClientGet:- " + e);
        }
    }
}
