引入maven依赖

新建webService接口
注意接口要添加注释@WebService，且要添加name和targetNamespace属性

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

@WebService(name = "likuWmsWsService",targetNamespace = "http://impl.service.system.ruoyi.com/")
public interface IWmsTestService {

    @WebMethod
    public String queryStock(@WebParam(name = "param") String param);
}

增加接口实现类

@WebService
@Configuration
public class WmsTestServiceImpl implements IWmsTestService {

    @Override
    public String queryStock(String param) {
        System.out.printf("接收的参数:"+param);
        Map<String, Object> returnMap = new HashMap<String, Object>();
        returnMap.put("data",new ArrayList<>());
        returnMap.put("MSGTY","S");
        returnMap.put("MSGTX","失败原因");
        return JSONObject.toJSONString(returnMap);
    }
}

增加发布webService的类

import com.ruoyi.system.service.IWmsTestService;
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.beans.factory.annotation.Autowired;
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 WebServicePublish {
    @Autowired
    private Bus bus;
    @Autowired
    private IWmsTestService wmsTestServiceImpl;

    /**
     * 用于注册CXFServlet的
     * 地址/webservice/*
     * * 通配符 更上接口地址
     *
     */
    @Bean("cxfServletRegistration")
    public ServletRegistrationBean dispatcherServlet() {
        // 这里就是发布服务的跟路径,后面 * 是通配符,表示跟什么都行
        return new ServletRegistrationBean<>(new CXFServlet(), "/webservice/*");
    }

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

    @Bean
    public Endpoint endpoint() {
        // 建立一个端点 ,第一个参数是 springBus 对象,第二个参数是刚才的接口实现类(因为在实现类中用了@service,所以这里可以自动注入)
        // PS: 要是有多个service,这个方法对象多写几个就行
        EndpointImpl endpoint = new EndpointImpl(bus, wmsTestServiceImpl);
        // 这里就是发布的这个接口的地址
        endpoint.publish("/wmsWs");
        return endpoint;
    }
}

服务启动成功后，通过浏览器访问wsdl地址
