Apache CXF

CXF一个开源的Service框架，它实现了JCP与Web Service中一些重要标准，CXF简化了构造，集成，面向服务架构（SOA）业务组件与技术的灵活复用。在CXF中，Service使用WSDL标准定义并能够使用各种不同的消息格式（或binding）和网络协议（transports）包括SOAP、XML（通过HTTP或JMS）进行访问。

CXF同样支持多种model 如：JAX-WS，JBI，SCA和CORBA service。

CXF设计成可灵活部署到各种容器中包括Spring-based，JBI，SCA， Servlet和J2EE容器。

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

@WebService(name = "userWebService",
        // 命名空间,一般是接口的包名倒序
        targetNamespace = "#34;
)
public interface UserWebService {

    @WebMethod
    @WebResult(name = "String", targetNamespace = "")
    String userInfo(@WebParam(name = "username") String username);

}  

 package com.what21.demo.service;

import org.springframework.stereotype.Component;

import javax.jws.WebService;

// 与接口中指定的name一致
@WebService(serviceName = "userWebService",
        // 与接口中的命名空间一致,一般是接口的包名倒
        targetNamespace = "#34;,
        // 接口地址
        endpointInterface = "com.what21.demo.service.UserWebService"

客户端调用WebService服务

实现

 package com.what21.demo.service;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;

public class WebServiceTest {


    public static void main(String[] args) {
        // 创建动态客户端
        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
        Client client = dcf.createClient("#34;);
        // 需要密码的情况需要加上用户名和密码
        // client.getOutInterceptors().add(new ClientLoginInterceptor(USER_NAME,PASS_WORD));
        Object[] objects = new Object[0];
        try {
            // invoke("方法名",参数1,参数2,参数3....);
            objects = client.invoke("userInfo", "wangyangming");
            System.out.println("返回数据：" + objects[0]);
        } catch (java.lang.Exception e) {
            e.printStackTrace();
        }
    }
}
