在Spring Boot(2.5.4)中集成CXF发布web服务(jax-ws)

步骤1：添加Maven依赖

因为cxf starter依赖版本的问题，踩过好几个坑，大家如果遇到没有明确解决线索的问题，可以尝试用最新版本试试。

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-spring-boot-starter-jaxws</artifactId>
    <version>3.4.4</version>
</dependency>

步骤2：定义业务接口

实测接口层是可以去掉的

package com.etoak.ws;

import javax.jws.WebService;

@WebService(name = "Hello01", targetNamespace = "http://ws.etoak.com")
public interface IWsBusi01 {

    String sayHello01();
}

步骤3：定义业务实现类

package org.etoak;

import com.etoak.ws.IWsBusi01;

import javax.jws.WebService;

/**
 * Hello world!
 *
 */
@WebService(serviceName = "Hello01", targetNamespace = "http://ws.etoak.com", endpointInterface = "com.etoak.ws.IWsBusi01")
public class WsBusi01Impl implements IWsBusi01 {

    @Override
    public String sayHello01() {
        System.out.println(">>>>>>>>>sayHello01");

        return "sayHello01";
    }
}

步骤4:发布Web服务

@Configuration
public class WebServiceConfig {
    @Autowired
    private Bus bus;

    @Bean
    public Endpoint endpoint1() {
        EndpointImpl endpoint = new EndpointImpl(bus, new WsBusi01Impl());
        //Web服务名称
        endpoint.publish("/Hello01");
        return endpoint;
    }


    @Bean
    public Endpoint endpoint2() {
        EndpointImpl endpoint = new EndpointImpl(bus, new WsBusi02Impl());
        endpoint.publish("/Hello02");
        return endpoint;
    }


    /*@Bean (name = "cxfServlet")
    public ServletRegistrationBean cxfServlet() {
        return new ServletRegistrationBean(new CXFServlet(), "/webservice/*");
    }

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


    // 手动发布
    @Bean
    public EndpointImpl serviceEndpoint() {
        EndpointImpl endpoint = null;
        
        // 获取配置的需要发布服务的列表
        // ...

        DefaultListableBeanFactory defaultListableBeanFactory = (DefaultListableBeanFactory) applicationContext.getAutowireCapableBeanFactory();
        for (迭代配置的服务列表) {
            // 实现类的全限定名称
            String clazzName;
            // 配置的自定义服务名
            String webServiceAnnotationName;
            try {
                Class<?> clazz = Class.forName(clazzName);
                Object o = clazz.newInstance();
                // 判断是否有@WebService注解
                WebService webServiceAnnotation = clazz.getAnnotation(WebService.class);
                if (webServiceAnnotation != null) {
                    if (StringUtils.hasLength(webServiceAnnotationName)) {
                        BeanDefinitionBuilder beanDefinitionBuilder = BeanDefinitionBuilder.genericBeanDefinition(EndpointImpl.class);
                        endpoint = new EndpointImpl((SpringBus) applicationContext.getBean(Bus.DEFAULT_BUS_ID), o);
                        endpoint.getInInterceptors().add(authInterceptor);
                        endpoint.publish(webServiceAnnotationName);

                        defaultListableBeanFactory.registerBeanDefinition(webServiceAnnotationName, beanDefinitionBuilder.getBeanDefinition());
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        return endpoint;
    }*/
}

步骤5：启动Spring Boot

访问:http://localhost:8080/services/Hello01?wsdl

服务发布成功

===============================================

实际上当时业务需求要稍微复杂一点，拆拆成了SpringBoot工程和业务工程，SpringBoot工程作为单独的Web应用启动，加载每一个业务工程jar包。所以在打包SpringBoot工程的时候，需要将第三方jar包分离出来，具体实现参考《关于打包jar/war_wsdhla的专栏-CSDN博客》

再加上XXL，最终架构如下：

==============================================

配置文件方式：

1 增加配置文件application-cxf.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
    <jaxws:endpoint implementor="com.xxx.XxxImpl" address="/demoServ"/>
</beans>

2 启动类读取配置文件

@ImportResource(locations = {"classpath:application-cxf.xml"})
