7、Web Service-IDEA-jaxws规范下的 服务端/客户端 开发

前提简介：这里之后即使基于IDEA进行开发的，风格与之前有些不同之处！

1、服务端的开发

1、创建新的项目

2、pom.xml

添加开发时所需要的依赖

      </plugins>
    </pluginManagement>
  </build>
</project>

3、工程目录：

4、类的设计

接口类：在客户端的接口类需要和服务端的接口类再同一个包中

helloService.java 

package com.cr.service;
import javax.jws.WebService;
//对外发布的接口
@WebService
public interface helloService {
    //对外发布服务接口的方法
    public String  sayHello(String name);
}

接口实现类

helloSericeImpl.java 

package com.cr.service.impl;
import com.cr.service.helloService;

public class helloSericeImpl implements helloService {
    @Override
    public String sayHello(String name) {
        return "欢迎"+name;
    }
}

发布服务：

package com.cr;

import com.cr.service.impl.helloSericeImpl;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

public class serverTest {

    public static void main(String[] args) {

        //发布服务的工厂
        JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();
        //设置服务地址
        factory.setAddress("http://localhost:8000/ws/hello");
        //设置服务类、
        factory.setServiceBean(new helloSericeImpl());
        //发布服务
        factory.create();
        System.out.println("发布服务成功....");
    }
}

此时的控制台的输出情况：

5、查看wsdl地址内容

浏览器输入地址＋ ？wsdl

阅读顺序自下向上

此时若需要读懂wsdl文件方向是自下向上

2、客户端的开发

1、创建项目（同上，以及pom文件的依赖）

2、工程结构

3、类的实现

接口类：这里的接口的包名需要和服务端的接口类报名保持一致

helloService.java 

package com.cr.service;

import javax.jws.WebService;

//对外发布服务的接口

@WebService 
public interface helloService { 
　　//对外发布服务接口的方法 
　　public String sayHello(String name);
 }

测试类：

package com.cr.test;

import com.cr.service.helloService;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

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

        //服务接口访问地址http://localhost:8000/ws/hello

        //创建cxf代理工厂
        JaxWsProxyFactoryBean factory= new JaxWsProxyFactoryBean();

        //设置服务的地址
        factory.setAddress("http://localhost:8000/ws/hello");

        //设置接口类型
        factory.setServiceClass(helloService.class);

        //对接口生成代理对象
        helloService helloService = factory.create(helloService.class);

        System.out.println(helloService.getClass());

        //远程访问服务端方法
        String qq = helloService.sayHello("qq");
        System.out.println(qq);
    }
}

这里的代理时时JDK代理class com.sun.proxy.$Proxy34

 

java中的代理：

1、静态代理

2、动态代理

 

动态代理包括：

1、jdk接口代理：$Proxy34

2、cglib代理：￥CGLIB123

问题：我们想要知道数据交互的格式：

在服务的添加log4j日志文件

log4j.appender.Stdout=org.apache.log4j.ConsoleAppender
log4j.appender.Stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.Stdout.layout.conversionPattern=%-5p - %-.26c{} - %m\n

log4j.rootLogger=INFO,Stdout

log4j.logger.org.apache.wicket=INFO
log4j.logger.org.apache.wicket.protocol.http.HttpSessionStore=INFO
log4j.logger.org.apache.wicket.version=INFO
log4j.logger.org.apache.wicket.RequestCycle=INFO

log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\file.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout

在测试的代码中：

package com.cr;

import com.cr.service.impl.helloSericeImpl;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

public class serverTest {

    public static void main(String[] args) {

        //发布服务的工厂
        JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();

        //设置服务地址
        factory.setAddress("http://localhost:8000/ws/hello");

        //设置服务类、
        factory.setServiceBean(new helloSericeImpl());

        //设置日志输入、输出拦截器、观察soap请求的相应内容
        factory.getInInterceptors().add(new LoggingInInterceptor());
        factory.getOutInterceptors().add(new LoggingOutInterceptor());

        //发布服务
        factory.create();

        System.out.println("发布服务成功....");
    }
}

此时再次请求Client

控制台中

ID:
Address: http://localhost:8000/ws/hello
Encoding: UTF-
Http-Method: POST
Content-Type: text/xml; charset=UTF-
Headers: {Accept=[*/*], Cache-Control=[no-cache], connection=[keep-alive], Content-Length=[188], content-type=[text/xml; charset=UTF-8], Host=[localhost:8000], Pragma=[no-cache], SOAPAction=[""], User-Agent=[Apache CXF 3.0.1]}
Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns2:sayHello xmlns:ns2="http://service.cr.com/"><arg0>qq</arg0></ns2:sayHello></soap:Body></soap:Envelope>
--------------------------------------
INFO  - helloService               - Outbound Message
---------------------------
ID: 1
Response-Code: 200
Encoding: UTF-8
Content-Type: text/xml
Headers: {}
Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns2:sayHelloResponse xmlns:ns2="http://service.cr.com/"><return>欢迎qq</return></ns2:sayHelloResponse></soap:Body></soap:Envelope>
--------------------------------------

此时可以看出请求与响应的相关消息！！
