摘要:本文首要介绍了SpringBoot
搭建WebService
服务的服务端开发,和WebService
的客户端开发,让不熟悉WebService
开发的同学能够快速入门。
WebService
服务端开发
pom.xml
引进首要的
maven jar
包

<dependency>

<artifactId>spring-boot-starter-web</artifactId>

提早界说一个UserDto
目标
@Data
public class UserDto {
private Long id;
private String userName;
private Boolean active;
}
声明服务接口
@WebService(name = HelloService.SERVICE_NAME,targetNamespace = HelloService.TARGET_NAMESPACE)
public interface HelloService {
/** 露出服务称号 */
String SERVICE_NAME = "HelloService";
/** 命名空间,一般是接口的包名倒序 */
String TARGET_NAMESPACE = "http://hello.server.webservice.huzhihui.com";
@WebMethod
@WebResult(name = "String")
String hi(@WebParam(name = "userName") String userName);
@WebMethod
@WebResult(name = "UserDto")
List<UserDto> activeUsers(@WebParam(name = "userDtos") List<UserDto> userDtos);
}
@WebParam
该注解标识传入的参数称号,必须要写
name
参数,否则生成的wsdl
参数称号是args1 args2 argsn
@WebResult
该注解标识回来的成果,必须加
name
参数,否则生成的wsdl
回来参数是return
界说接口完成
@WebService(
/** 和接口的服务称号保持一致 */
serviceName = HelloService.SERVICE_NAME,
/** 和接口的命名空间保持一致 */
targetNamespace = HelloService.TARGET_NAMESPACE,
/** 接口全途径 */
endpointInterface = "com.huzhihui.webservice.server.hello.HelloService"
)
@BindingType(value = "http://www.w3.org/2003/05/soap/bindings/HTTP/")
@Component
public class HelloServiceImpl implements HelloService {
@Override
public String hi(String userName) {
return "hi " + userName;
}
@Override
public List<UserDto> activeUsers(List<UserDto> userDtos) {
for (UserDto userDto : userDtos) {
userDto.setActive(Boolean.TRUE);
}
return userDtos;
}
}
注解WebService
服务
@Configuration
public class HelloEndpointConfig {
@Autowired
private Bus bus;
@Autowired
private HelloService helloService;
@Bean
public Endpoint helloEndpoint(){
EndpointImpl endpoint = new EndpointImpl(bus,helloService);
endpoint.publish("/helloService");
return endpoint;
}
}
注意
如果有多个
WebService
接口则按照上面的过程多写几个接口就行了。
发动服务端
拜访wsdl
发布的接口
地址是
http://localhost:8080/services/helloService?wsdl
; 如果新增了其他WebService
服务接口地址是你装备的endpoint.publish("/xxxx");
http://localhost:8080/services/xxxx?wsdl
客户端开发
java
调用WebService
一般有三种办法;
- 生成客户端代码拜访
-
JaxWsDynamicClientFactory
动态拜访 -
HttpClient
直接发送xml
报文拜访(最原始的办法)
我接下来将依次供给事例来拜访
提早装备pom.xml
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-spring-boot-starter-jaxws</artifactId>
<version>3.3.4</version>
<exclusions>
<exclusion>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
</exclusion>
</exclusions>
</dependency>
生成客户端代码拜访
idea
插件装置
运用插件生成代码
插件最好运用
jdk8
或许jdk6
的环境,其他jdk
版别可能会报错。
运用客户端代码
在我们装备的包下面会生成一个
helloService.wsdl
文件,我一般是修改了生成的HelloService_service
中的wsdl
文件地址为本地途径,
改为了如下装备
我加上了
@Component
就能在Spring
中运用了
拜访该地址就能拜访到接口了
JaxWsDynamicClientFactory
动态拜访
该形式是最精简的拜访形式,只不过要求能看到
wsdl
文件恳求参数和回来参数的结构界说,这里不详细说结构了,自己百度
一般数据类型拜访事例
如果恳求参数和回来参数都是
java
的基础数据类型,运用如下代码即可
public static void hi() throws Exception{
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient("http://localhost:8080/services/helloService?wsdl");
Object[] objects = client.invoke("hi","zhangsan");//hi办法名 后边是可变参数
//输出调用成果
System.out.println(objects[0].getClass());
System.out.println(objects[0].toString());
}
拜访成果
数据结构拜访事例
我们需要把用到的数据目标界说在
WebService
的targetNamespace
反过来的包下面,然后再来调用接口,
public static void activeUsers() throws Exception{
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient("http://localhost:8080/services/helloService?wsdl");
List<Object> userDtos = new ArrayList<>();
UserDto userDto = new UserDto();
userDto.setId(1L);
userDto.setUserName("zs");
userDtos.add(userDto);
Object[] objects = client.invoke("activeUsers",userDtos);//list3办法名 后边是可变参数
//输出调用成果
System.out.println(objects[0].getClass());
System.out.println(objects[0].toString());
}
上面的事例用到了
UserDto
类,我就界说如下(注意包名)
package com.huzhihui.webservice.server.hello;
import lombok.Data;
@Data
public class UserDto {
private Long id;
private String userName;
private Boolean active;
}
成果如下
HttpClient
直接发送xml
报文拜访
public static void restTemplateActiveUsers(){
RestTemplate restTemplate = new RestTemplate();
long start = System.currentTimeMillis();
//<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:hel="http://hello.server.webservice.huzhihui.com">
// <soap:Header/>
// <soap:Body>
// <hel:activeUsers>
// <!--Zero or more repetitions:-->
// <userDtos>
// <!--Optional:-->
// <active></active>
// <!--Optional:-->
// <id>1</id>
// <!--Optional:-->
// <userName>hzh</userName>
// </userDtos>
// </hel:activeUsers>
// </soap:Body>
//</soap:Envelope>
//结构webservice恳求参数
StringBuffer soapRequestData = new StringBuffer();
soapRequestData.append("<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:hel="http://hello.server.webservice.huzhihui.com">");
soapRequestData.append("<soap:Header/>");
soapRequestData.append("<soap:Body>");
soapRequestData.append("<hel:activeUsers>");
soapRequestData.append("<userDtos>");
soapRequestData.append("<active></active>");
soapRequestData.append("<id>1</id>");
soapRequestData.append("<userName>hzh</userName>");
soapRequestData.append("</userDtos>");
soapRequestData.append("</hel:activeUsers>");
soapRequestData.append("</soap:Body>");
soapRequestData.append("</soap:Envelope>");
//结构http恳求头
HttpHeaders headers = new HttpHeaders();
MediaType type = MediaType.parseMediaType("text/xml;charset=UTF-8");
headers.setContentType(type);
HttpEntity<String> formEntity = new HttpEntity<>(soapRequestData.toString(), headers);
//回来成果
String resultStr = restTemplate.postForObject("http://localhost:8080/services/helloService?wsdl", formEntity, String.class);
System.out.println(resultStr);
}
成果如下
至于
xml
转java
目标,工具很多,自己随便找找就有了,我项目中运用的是jackson xml
xml
转目标
- 界说的
DTO
@Data
@JacksonXmlRootElement(localName = "soap:Envelope")
public class EnvelopeDto {
@JacksonXmlProperty(localName = "soap:Body")
private BodyDto bodyDto;
@JacksonXmlProperty(localName = "xmlns:soap",isAttribute = true)
private String xmlnsSoap;
}
@Data
@JacksonXmlRootElement(localName = "soap:Body")
public class BodyDto {
@JacksonXmlElementWrapper(localName = "ns2:activeUsersResponse")
@JacksonXmlProperty(localName = "UserDto")
private List<UserDto> userDtos;
}
@Data
@NoArgsConstructor
@AllArgsConstructor
@JacksonXmlRootElement(localName = "UserDto")
public class UserDto {
@JacksonXmlProperty(localName = "id")
private Long id;
@JacksonXmlProperty(localName = "userName")
private String userName;
@JacksonXmlProperty(localName = "active")
private Boolean active;
}
- 测验办法
@Test
void xmlToObj() throws Exception{
String value = "<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope"><soap:Body><ns2:activeUsersResponse xmlns:ns2="http://hello.server.webservice.huzhihui.com"><UserDto><active>true</active><id>1</id><userName>hzh</userName></UserDto><UserDto><active>true</active><id>2</id><userName>zs</userName></UserDto></ns2:activeUsersResponse></soap:Body></soap:Envelope>\n";
XMLInputFactory input = new WstxInputFactory();
input.setProperty(XMLInputFactory.IS_NAMESPACE_AWARE, Boolean.FALSE);
XmlMapper xmlMapper = new XmlMapper(new XmlFactory(input,new WstxOutputFactory()));
EnvelopeDto envelopeDto = xmlMapper.readValue(value,EnvelopeDto.class);
System.out.println(envelopeDto);
}
