WebService是一个比较旧的远程调用通信框架现在企业项目中用的比较少因为它逐步被SpringCloud所取代它的优势就是能够跨语言平台通信所以还有点价值下面来看看如何在SpringBoot项目中使用WebService
我们模拟从WebService客户端发送请求给WebService服务端暴露的下载文件服务并获取服务端返回的文件保存到本地
环境
SpringBoot2.7.3
Jdk17
服务端
在SpringBoot中整合WebService的服务端需要通过一个配置文件将服务接口暴露出去给客户端调用
项目结构 配置
服务端POM

服务端YML
server: # 必须配置端口客户端需要port: 7001FileCxfConfig
该文件为WebService服务暴露配置文件
package com.example.webservice.config;import com.example.webservice.service.FileCxfService;
import com.example.webservice.service.impl.FileCxfServiceImpl;
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 FileCxfConfig {Bean(name Bus.DEFAULT_BUS_ID)public SpringBus springBus() {return new SpringBus();}Bean(name downloadFileBean)public ServletRegistrationBean dispatcherServlet() {ServletRegistrationBean wbsServlet new ServletRegistrationBean(new CXFServlet(), /file/*);return wbsServlet;}Beanpublic FileCxfService fileCxfService() {return new FileCxfServiceImpl();}Beanpublic Endpoint endpointPurchase(SpringBus springBus, FileCxfService fileCxfService) {EndpointImpl endpoint new EndpointImpl(springBus(), fileCxfService());endpoint.publish(/download);System.err.println(服务发布成功地址为http://localhost:7001/file/download?wsdl);return endpoint;}}FileCxfService
该类指定了暴露的服务接口注意类中的注解都很重要不能丢具体可以看说明
package com.example.webservice.service;import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.xml.ws.BindingType;BindingType(value http://www.w3.org/2003/05/soap/bindings/HTTP/)
WebService(serviceName FileCxfService, // 与接口中指定的name一致targetNamespace http://webservice.example.com // 与接口中的命名空间一致,一般是接口的包名倒
)
public interface FileCxfService {WebMethod(operationName downloadFile)WebResult(name String)String downloadFile(WebParam(name params, targetNamespace http://webservice.example.com) String params,WebParam(name token, targetNamespace http://webservice.example.com) String token);}
FileCxfServiceImpl
该类指定了暴露的服务接口的具体实现注意类中的注解都很重要不能丢具体可以看说明
package com.example.webservice.service.impl;import cn.hutool.core.codec.Base64;
import com.alibaba.fastjson2.JSONObject;
import com.example.webservice.pojo.FileDto;
import com.example.webservice.service.FileCxfService;import javax.jws.WebService;WebService(serviceName FileCxfService, // 与接口中指定的name一致targetNamespace http://webservice.example.com // 与接口中的命名空间一致,一般是接口的包名倒
)
public class FileCxfServiceImpl implements FileCxfService {Overridepublic String downloadFile(String params, String token) {//下载文件System.err.println(params : params);FileDto fileDto JSONObject.parseObject(params, FileDto.class);System.err.println(fileDto : fileDto);String data null;try {data Base64.encode(C:\\Users\\YIQI\\Desktop\\ebook\\Java70.pdf);} catch (Exception e) {e.printStackTrace();}System.err.println(data);return data;}}
FileDto
该类为参数实体类用于接受客户端传来的参数
package com.example.webservice.pojo;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.ToString;Data
AllArgsConstructor
ToString
public class FileDto {private String fileId;private String newFileId;private String bucketName;}
客户端
在SpringBoot中整合WebService的客户端需要指定服务端暴露的服务接口
项目结构 配置
客户端POM
?xml version1.0 encodingUTF-8?

客户端YML
server: # 可以不配置port: 1000FileCxfService
这个文件和服务端的FileCxfService保持一致用于指定客户端请求的方式
package com.example.webclient.service;import javax.jws.WebParam;
import javax.jws.WebService;WebService(name FileCxfService, // 暴露服务名称targetNamespace http://webservice.example.com// 命名空间,一般是接口的包名倒序
)
public interface FileCxfService {String downloadFile(WebParam(name data, targetNamespace http://webservice.example.com) String data,WebParam(name token, targetNamespace http://webservice.example.com) String token);}
FileCxfClient
这个类是客户端的主类里面有发送WebService请求的方法
package com.example.webclient.client;import cn.hutool.core.codec.Base64;
import com.alibaba.fastjson2.JSONObject;
import com.example.webclient.pojo.FileDto;
import com.example.webclient.service.FileCxfService;
import com.example.webclient.util.ConvertBASE64;import javax.xml.bind.DatatypeConverter;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import java.net.URL;public class FileCxfClient {public static void main(String[] args) throws Exception {// 创建wsdl的urlURL url new URL(http://localhost:7001/file/download?wsdl);// 指定命名空间和服务名称QName qName new QName(http://webservice.example.com, FileCxfService);Service service Service.create(url, qName);// 通过getPort方法返回指定接口FileCxfService myServer service.getPort(FileCxfService.class);// 调用方法返回数据FileDto fileDto new FileDto();fileDto.setFileId(1);fileDto.setNewFileId(1);fileDto.setBucketName(book);String params JSONObject.toJSONString(fileDto);Long st System.currentTimeMillis();String file myServer.downloadFile(params, TOKEN:ABC);// 解析文件到本地// 可以解析成字节数组如果服务端返回的也是字节数组的话byte[] decode Base64.decode(file);// 也可以将Base64写入到本地文件中ConvertBASE64.decoderBase64File(file, C:\\Users\\YIQI\\Desktop\\ebook\\demo70.pdf);System.err.println(decode : decode.toString());System.err.println(result get file success!);System.err.println(cost time : (System.currentTimeMillis() - st) / 1000 s.);}}
FileDto
这个类是封装请求参数的实体类和服务端的FileDto保持一致
package com.example.webclient.pojo;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;Data
AllArgsConstructor
NoArgsConstructor
ToString
public class FileDto {private String fileId;private String newFileId;private String bucketName;}
ConvertBASE64
该类是Base64工具类可以完成Base64字符串和文件的互换
package com.example.webclient.util;import cn.hutool.core.codec.Base64Decoder;
import cn.hutool.core.codec.Base64Encoder;
import cn.hutool.core.io.FileUtil;
import com.alibaba.fastjson2.JSONObject;import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;public class ConvertBASE64 {/*** 将文件转成base64编码字符串** param path* return* throws Exception*/public static String encodeBase64File(String path) throws Exception {File file new File(path);FileInputStream inputFile new FileInputStream(file);byte[] buffer new byte[(int) file.length()];inputFile.read(buffer);inputFile.close();return new Base64Encoder().encode(buffer);}/*** 将base64编码字符串转成文件** param base64Code* param targetPath* throws Exception*/public static void decoderBase64File(String base64Code, String targetPath)throws Exception {byte[] buffer Base64Decoder.decode(base64Code);FileOutputStream out new FileOutputStream(targetPath);out.write(buffer);out.close();}/*** 将base64字节装成文件** param base64Code* param targetPath* throws Exception*/public static void toFile(String base64Code, String targetPath)throws Exception {byte[] buffer base64Code.getBytes();FileOutputStream out new FileOutputStream(targetPath);out.write(buffer);out.close();}public static String toJson(Object obj) {return JSONObject.toJSONString(obj);}public static Object toObject(String JSONString, Class cls) {return JSONObject.parseObject(JSONString, cls);}public static void writeByteArrayToFile(File desFile, byte[] data)throws IOException {FileUtil.writeBytes(data, desFile);}public static byte[] readFileToByteArray(File srcFile)throws IOException {return FileUtil.readBytes(srcFile);}public static String encode(String string) {return new String(Base64Encoder.encode(string.getBytes()));}public static void main(String[] args) {try {String a encodeBase64File(C:\\Users\\YIQI\\Desktop\\工作文件\\bg2.jpg);// String base64Code encodeBase64File(D:/0101-2011-qqqq.tif);System.out.println(a);decoderBase64File(a, C:\\Users\\YIQI\\Desktop\\工作文件\\bg3.jpg);// toFile(base64Code, D:\\three.txt);} catch (Exception e) {e.printStackTrace();}}}
测试
先启动服务端可以看到对外发布的服务 在启动客户端给服务端发送请求的方法可以看到服务端返回的数据 因为我把从服务端获取的文件写入到了本地所以可以在文件目录中看到该文件
