JBoss Fuse - Layanan Web Istirahat

Pertama-tama, REST adalah singkatan dari Representational State Transfer. Ini adalah cara mengembangkan layanan web berdasarkan protokol server-klien tanpa status, dapat disimpan dalam cache, yang dalam banyak kasus merupakan HTTP.

Layanan web REST menggunakan permintaan HTTP untuk memposting, mendapatkan, menghapus data dari jaringan.

Pengembangan REST menggunakan CXF

Buat Kelas Layanan

Buat kelas UserService.java di bawah com / tuts /

package com.tuts;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/UserService_1")
public class UserService {
   @GET
   @Path("/get_data")
   @Produces(MediaType.APPLICATION_JSON)
	
   public String getUser() {
      String reponse = "This is standard response from REST";
      return reponse;
   }
}

Buat Blueprint.xml

Buat cetak biru.xml di bawah / src / main / resources / OSGI-INF / blueprint blueprint.xml

<?xml version = "1.0" encoding = "UTF-8"?>
<blueprint xmlns = "http://www.osgi.org/xmlns/blueprint/v1.0.0"
   xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" 
   xmlns:jaxrs = "http://cxf.apache.org/blueprint/jaxrs"
   xsi:schemaLocation = "http://www.osgi.org/xmlns/blueprint/v1.0.0 
   http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
   http://cxf.apache.org/blueprint/jaxrs 
   http://cxf.apache.org/schemas/blueprint/jaxrs.xsd">
	
   <jaxrs:server id = "service" address = "/users">
      <jaxrs:serviceBeans>
         <ref component-id = "userService" />
      </jaxrs:serviceBeans>
   </jaxrs:server>
	
   <bean id = "userService" class = "com.tuts.UserService" />
</blueprint>

Instal layanan Istirahat di Fuse

install -s mvn:com.tuts.abhinav/rest-service/1.0-SNAPSHOT

Periksa apakah Bundle memiliki Layanan Web Terdaftar

Buka URL http://localhost:8181/cxf

Uji Layanan Web

Buka URL http://localhost:8181/cxf/users12/UserService_1/get_data
