3. 开始编写webService服务端

3.1 实体类entity

package com.mracale.springboot.Entity;

import java.io.Serializable;

/**
 *用户实体类
 */
public class User implements Serializable {
    private static final long serialVersionUID = -3628469724795296287L;

    private String userId;
    private String userName;
    private String email;

    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Override
    public String toString() {
        return "User{" +
                "userId='" + userId + '\'' +
                ", userName='" + userName + '\'' +
                ", email='" + email + '\'' +
                '}';
    }
}

3.2 服务接口

package com.mracale.springboot.Service;

import com.mracale.springboot.Entity.User;

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

//@WebService(targetNamespace="http://service.springboot.mracale.com")如果不添加的话,动态调用invoke的时候,会报找不到接口内的方法,具体原因未知.
@WebService(targetNamespace="http://service.springboot.mracale.com")
public interface UserService {

    @WebMethod//标注该方法为webservice暴露的方法,用于向外公布，它修饰的方法是webservice方法，去掉也没影响的，类似一个注释信息。
    public User getUser(@WebParam(name = "userId") String userId);

    @WebMethod
    @WebResult(name="String",targetNamespace="")
    public String getUserName(@WebParam(name = "userId") String userId);

}

3.3 服务接口的实现类

package com.mracale.springboot.Service.impl;

import java.util.HashMap;
import java.util.Map;
import java.util.UUID;

import javax.jws.WebService;

import com.mracale.springboot.Entity.User;
import com.mracale.springboot.Service.UserService;
import org.springframework.stereotype.Component;

/**
 * @ClassName:UserServiceImpl
 * @Description:测试服务接口实现类
 */
@WebService(serviceName="UserService",//对外发布的服务名
        targetNamespace="http://service.springboot.mracale.com",//指定你想要的名称空间，通常使用使用包名反转
        endpointInterface="com.mracale.springboot.Service.UserService")//服务接口全路径, 指定做SEI（Service EndPoint Interface）服务端点接口
@Component
public class UserServiceImpl implements UserService {

    private Map<String, User> userMap = new HashMap<String, User>();
    public UserServiceImpl() {
        System.out.println("向实体类插入数据");
        User user = new User();
        user.setUserId(UUID.randomUUID().toString().replace("-", ""));
        user.setUserName("mracale01");
        user.setEmail("mracale01@163.xom");
        userMap.put(user.getUserId(), user);

        user = new User();
        user.setUserId(UUID.randomUUID().toString().replace("-", ""));
        user.setUserName("mracale02");
        user.setEmail("mracale02@163.xom");
        userMap.put(user.getUserId(), user);

        user = new User();
        user.setUserId(UUID.randomUUID().toString().replace("-", ""));
        user.setUserName("mracale03");
        user.setEmail("mracale03@163.xom");
        userMap.put(user.getUserId(), user);
    }
    @Override
    public String getUserName(String userId) {
        return "userId为：" + userId;
    }
    @Override
    public User getUser(String userId) {
        System.out.println("userMap是:"+userMap);
        return userMap.get(userId);
    }

}

3.4 发布webService的配置

package com.mracale.springboot.config;

import com.mracale.springboot.Service.UserService;
import com.mracale.springboot.Service.impl.UserServiceImpl;
import org.apache.cxf.Bus;
import org.apache.cxf.bus.spring.SpringBus;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.transport.servlet.CXFServlet;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.xml.ws.Endpoint;

@Configuration
public class CxfConfig {

    /**
     * 此方法作用是改变项目中服务名的前缀名，此处127.0.0.1或者localhost不能访问时，请使用ipconfig查看本机ip来访问
     * 此方法被注释后:wsdl访问地址为http://127.0.0.1:8080/services/user?wsdl
     * 去掉注释后：wsdl访问地址为：http://127.0.0.1:8080/soap/user?wsdl
     * @return
     */
    @SuppressWarnings("all")
    @Bean
    public ServletRegistrationBean dispatcherServlet() {
        return new ServletRegistrationBean(new CXFServlet(), "/soap/*");
    }

    @Bean(name = Bus.DEFAULT_BUS_ID)
    public SpringBus springBus()
    {
        return  new SpringBus();
    }

    @Bean
    public UserService userService()
    {
        return  new UserServiceImpl();
    }

    @Bean
    public Endpoint endpoint() {
        EndpointImpl endpoint=new EndpointImpl(springBus(), userService());//绑定要发布的服务
        endpoint.publish("/user"); //显示要发布的名称
        return endpoint;
    }
}

4. 项目启动后的wsdl信息

5. 两种调用方式

package com.mracale.springboot.client;

import com.mracale.springboot.Service.UserService;
import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;

/**
 * @ClassName:CxfClient
 * @Description:webservice客户端：
 *                 该类提供两种不同的方式来调用webservice服务
 *              1：代理工厂方式
 *              2：动态调用webservice
 */
public class CxfClient {

    public static void main(String[] args) {
//        CxfClient.main1();
        CxfClient.main2();
    }

    /**
     * 1.代理类工厂的方式,需要拿到对方的接口地址
     */
    public static void main1() {
        try {
            // 接口地址
            String address = "http://127.0.0.1:8080/soap/user?wsdl";
            // 代理工厂
            JaxWsProxyFactoryBean jaxWsProxyFactoryBean = new JaxWsProxyFactoryBean();
            // 设置代理地址
            jaxWsProxyFactoryBean.setAddress(address);
            // 设置接口类型
            jaxWsProxyFactoryBean.setServiceClass(UserService.class);
            // 创建一个代理接口实现
            UserService us = (UserService) jaxWsProxyFactoryBean.create();
            // 数据准备
            String userId = "maple";
            // 调用代理接口的方法调用并返回结果
            String result = us.getUserName(userId);
            System.out.println("返回结果:" + result);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    /**
     * 2：动态调用
     */
    public static void main2() {
        // 创建动态客户端
        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
        Client client = dcf.createClient("http://127.0.0.1:8080/soap/user?wsdl");
        // 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[];
        try {
            // invoke("方法名",参数1,参数2,参数3....);
            objects = client.invoke("getUserName", "maple");
            System.out.println("返回数据:" + objects[]);
        } catch (java.lang.Exception e) {
            e.printStackTrace();
        }
    }
}

6. 注意点.

诚如之前所说,如果接口的注解上不加targetNamespace的话，动态调用的时候，会报如下的错误。
