创建入口

ApplicationContextUtils.java

bean调用工具

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

/**
 * 创建日期：2024-07-01
 */
@Component
public class ApplicationContextUtils implements ApplicationContextAware {
    //构造函数私有化，防止其它人实例化该对象
    private ApplicationContextUtils(){}
    private static ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        ApplicationContextUtils.applicationContext = applicationContext;
    }

    //通过name获取 Bean.（推荐，因为bean的name是唯一的，出现重名的bean启动会报错。）
    public static Object getBean(String name) {
        return applicationContext.getBean(name);
    }

    //通过class获取Bean.（确保bean的name不会重复。因为可能会出现在不同包的同名bean导致获取到2个实例）
    public static <T> T getBean(Class<T> clazz) {
        return applicationContext.getBean(clazz);
    }

    //通过name,以及Clazz返回指定的Bean（这个是最稳妥的）
    public static <T> T getBean(String name, Class<T> clazz) {
        return applicationContext.getBean(name, clazz);
    }

}

IWebService.java

统一入口

public interface IWebService {

    String handle(String parameter);

}

WebServiceEntry.java

import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;

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

/**
 * 创建日期：2024-07-01
 */
@Slf4j
@Service
@WebService
public class WebServiceEntry {
	/**
     * 反射调用方法
     * @param service bean name
     * @param parameter 请求参数字符串，一般是xml格式的字符串
     */
    @WebMethod
    public String invoke(@WebParam(name = "service") String service,
                  @WebParam(name = "parameter") String parameter) {
        IWebService webService = (IWebService) ApplicationContextUtils.getBean(service);
        return webService.handle(parameter);
    }

}

WebServiceConfig.java

配置类
有些依赖千万不要导错，所以我依赖都粘贴进来了。防止导错包。

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;

/**
 * 创建日期：2024-07-01
 */
@Configuration
public class WebServiceConfig {

    @Bean(name = "cxfServlet")
    public ServletRegistrationBean<?> cxfServlet() {
        //urlMappings默认是：services
        return new ServletRegistrationBean<>(new CXFServlet(), "/services/*");
    }

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

    @Bean
    public Endpoint helloServiceEndpoint() {
        EndpointImpl endpoint = new EndpointImpl(springBus(), new WebServiceEntry());
        //services后面的uri地址
        endpoint.publish("/WebServiceEntry");
        return endpoint;
    }

}

WebMvcConfig.java

web的配置类，因为增加了xml依赖，springboot会默认把json放到xml后面，因此要手动改回默认json。

import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.web.servlet.config.annotation.ContentNegotiationConfigurer;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Override
    public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
        //引入 jackson-dataformat-xml 后，原本默认返回json变成了默认返回xml。因此这里要设置默认返回json
        configurer.defaultContentType(MediaType.APPLICATION_JSON);
    }

}

实现IWebService接口

如：WebServiceImpl

@Service("Hello")
public class Hello implements IWebService {

    @Override
    public String handle(String parameter) {
        return "hello";
    }

}

启动SpringBoot

访问

http://localhost:8080/services/WebServiceEntry?wsdl

会出现如下所示界面

用soapUI去调用接口
ws="http://ws.bsjkt.bsoft.com/"这里每个人可能不一样
service=bean name
parameter=请求参数

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ws="http://ws.bsjkt.bsoft.com/">
<soapenv:Header/>
<soapenv:Body>
<ws:invoke>
<service>Hello</service>
<parameter><![CDATA[
<Data>
</Data>
]]></parameter>
      </ws:invoke>
   </soapenv:Body>
</soapenv:Envelope>
