网络服务接口开发分为服务端与客户端，本文已SpringBoot框架为例，先介绍下服务端的开发。

开发服务端

步骤：

1. 引入依赖
2. 写实体类
3. 写服务接口和实现类
4. 写配置类

pom文件引入依赖：

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-spring-boot-starter-jaxws</artifactId>
    <version>3.2.5</version>
</dependency>

<!--    不引入会报错  报接口未实现  -->
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.0.18.Final</version>
</dependency>

实体类User

package com.bbzd.mws.model;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

/**
 * 为开发方便，引用了lombok标签
 * @date 2022/10/8 - 17:34
 */
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private String name;
    private Integer age;
}

service接口

package com.bbzd.mws.service;

import com.bbzd.mws.model.User;

import javax.jws.WebService;

/**
 *
 * @date 2022/10/8 - 17:37
 */
@WebService(targetNamespace = "wsdl.bbzdmws.com",name = "uerPortType")
public interface UserService {

    User getUserName(String userName);
}

service接口实现类

package com.bbzd.mws.service.impl;

import com.bbzd.mws.model.User;
import com.bbzd.mws.service.UserService;

import javax.jws.WebService;

/**
 * @author Wangjzh
 * @date 2022/10/8 - 17:38
 */
@WebService(
        targetNamespace = "wsdl.bbzdmws.com", //命名空间 指定wsdl说明书在Client端所存放的包路径为com.aerfazhe.wsdl包下
        name = "userPortType",
        serviceName = "userService", //服务Name名称
        portName = "userPortName",
        endpointInterface = "com.bbzd.mws.service.UserService" // 指定webService的接口类，此类也需要接入@WebService注解
)
public class UserServiceImpl implements UserService {

    @Override
    public User getUserName(String name) {
        User user = new User(name, 28);
        return user;
    }
}

配置类

package com.bbzd.mws.config;

import com.bbzd.mws.service.UserService;
import com.bbzd.mws.service.impl.UserServiceImpl;
import org.apache.cxf.Bus;
import org.apache.cxf.bus.spring.SpringBus;
import org.apache.cxf.jaxws22.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;


/**
 * @date 2022/10/8 - 17:47
 */
@Configuration
public class CxfWebServiceConfig {
    @Bean("cxfServletRegistration")
    public ServletRegistrationBean<CXFServlet> dispatcherServlet() {
        return new ServletRegistrationBean<>(new CXFServlet(),"/ws/*");
    }

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

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

    @Bean
    public Endpoint endpoint(UserService userService) {
        EndpointImpl endpoint = new EndpointImpl(springBus(), userService);
        endpoint.publish("/user");
        return endpoint;
    }
}

运行程序，访问wsdl文件地址：
http://localhost:8889/mws/ws/user?wsdl

总结

1. 能见到运行结果，就说明服务端已经运行起来了。
2. 具体是否能够响应通信请求，还需要一个客户端才能测试，后面一篇是客户端如何开发，关注我，持续给您带来简单，实用的Java编程技巧。
3. 没有对输入进行验证，后面研究下怎么把验证框架加上。
