Webservice之發佈

WebService 簡單來講就是一種跨編程語言和跨操做系統平臺的遠程調用技術。

     XML+XSD,SOAP和WSDL是構成WebService平臺的三大技術

WebService開發主要分爲服務器端開發和客戶端開發兩個方面

Service:

服務端接口

import java.util.List;
import javax.jws.WebMethod;
import javax.jws.WebService;
@WebService
public interface Service {
    @WebMethod
    public String test(String word) ;
    @WebMethod
    public List<Student> getStudents();
}

接口實現類：

import java.util.ArrayList;
import java.util.List;
 
import javax.jws.WebService;

@WebService
public class ServiceImpl implements Service {
     
    public List<Student> getStudents() {
        List<Student> students = new ArrayList<Student>();
        students.add(new Student("aa", "aa"));
        students.add(new Student("bb", "bb"));
        students.add(new Student("cc", "cc"));
        students.add(new Student("dd", "dd"));

        return students;
    } 
    public String test(String word) {
        return "hello"+word;
    }

}

發佈類(能夠採用jdk發佈，也能夠採用cxf發佈)

import javax.xml.ws.Endpoint;

import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

public class ServiceTest {
          public static void main(String[] args) {
          Service service = new ServiceImpl();
          String address = "http://localhost:1000/Exercise";
          //Jdk發佈
//          Endpoint endpoint = Endpoint.publish(address, service);
         //CXF發佈
          JaxWsServerFactoryBean factoryBean = new JaxWsServerFactoryBean();
          factoryBean.setAddress(address);
          factoryBean.setServiceClass(Service.class);
          factoryBean.setServiceBean(service);
          factoryBean.create();
          System.out.println("publish success");
        }
}

瀏覽器輸入網址 http://localhost:1000/Exercise?wsdl

出現如下則發佈成功
