Spring Boot项目中，调用遗留的SOAP Web Service，方法很简单，仅需引入spring-boot-starter-web-services。

我们使用WebServiceTemplate来调用SOAP Service。WebServiceTemplate提供了三类调用方法sendSourceAndReceive、marshalSendAndReceive、sendAndReceive。sendSourceAndReceive方法直接发送和接收XML message；marshalSendAndReceive方法发送、接收结果则为对象，由配置的Marshaller和Unmarshaller自动转换；sendAndReceive支持更底层的操作。
package org.iata.caims.service.ws;
import org.springframework.boot.webservices.client.WebServiceTemplateBuilder;
import org.springframework.stereotype.Service;
import org.springframework.ws.client.core.WebServiceTemplate;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import java.io.StringReader;
@Service
public class MyService {
private static final String DEFAULT_URI = "http://localhost:8080/HelloService";
private static final String MESSAGE = "" +
"\n" +
" COCO \n" +
" ";
private final WebServiceTemplate webServiceTemplate;
public MyService(WebServiceTemplateBuilder webServiceTemplateBuilder) {
this.webServiceTemplate = webServiceTemplateBuilder.setDefaultUri(DEFAULT_URI).build();
}
public void sendSourceAndReceive() {
StreamSource source = new StreamSource(new StringReader(MESSAGE));
StreamResult result = new StreamResult(System.out);
webServiceTemplate.sendSourceAndReceiveToResult(source, result);
}
public Object marshalSendAndReceive(String uri, Object requestPayload) {
return this.webServiceTemplate.marshalSendAndReceive(uri, requestPayload);
}
}marshalSendAndReceive是常用的方法。您可以通过阅读wsdl文件来了解Web Service支持的方法和参数，也可以使用SoapUI工具生成request、response XML，然后手工编写SOAP Domain对象。更简单的方法是使用maven-jaxb2-plugin插件自动生成。
org.jvnet.jaxb2.maven2
maven-jaxb2-plugin
0.14.0
generate
org.itrunner.ws
${project.basedir}/src/main/java
${project.basedir}/src/main/resources/wsdl
*.wsdl
如上配置，将wsdl文件放入resources/wsdl文件夹，maven编译时将在指定包生成所有Web Service方法相关的stub类，其中包括package-info.java、ObjectFactory、request、response，并已配置好XML注解。
package-info.java
@javax.xml.bind.annotation.XmlSchema(namespace = "http://webservice.itrunner.org", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package org.iata.caims.service.test;ObjectFactory
import javax.xml.bind.annotation.XmlRegistry;
@XmlRegistry
public class ObjectFactory {
/**
* Create a new ObjectFactory that can be used to create new instances of schema derived classes for package: org.itrunner.ws
*/
public ObjectFactory() {
}
/**
* Create an instance of {@link SayHello }
*/
public SayHello createSayHello() {
return new SayHello();
}
/**
* Create an instance of {@link SayHelloResponse }
*/
public SayHelloResponse createSayHelloResponse() {
return new SayHelloResponse();
}
}Request
Request类名对应Web Service方法名，属性对应Web Service参数。
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
"in0"
})
@XmlRootElement(name = "sayHello")
public class SayHello {
@XmlElement(required = true, nillable = true)
protected String in0;
/**
* Gets the value of the in0 property.
*
* @return possible object is {@link String }
*/
public String getIn0() {
return in0;
}
/**
* Sets the value of the in0 property.
*
* @param value allowed object is {@link String }
*/
public void setIn0(String value) {
this.in0 = value;
}
}Response
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
"out"
})
@XmlRootElement(name = "sayHelloResponse")
public class SayHelloResponse {
@XmlElement(required = true, nillable = true)
protected String out;
/**
* Gets the value of the out property.
*
* @return possible object is {@link String }
*/
public String getOut() {
return out;
}
/**
* Sets the value of the out property.
*
* @param value allowed object is {@link String }
*/
public void setOut(String value) {
this.out = value;
}
}配置WebServiceTemplateBuilde与Jaxb2Marshaller：
import org.springframework.boot.webservices.client.HttpWebServiceMessageSenderBuilder;
import org.springframework.boot.webservices.client.WebServiceTemplateBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.ws.client.core.WebServiceTemplate;
import static java.time.Duration.ofSeconds;
@Configuration
public class Config {
@Bean
public WebServiceTemplate webServiceTemplate(WebServiceTemplateBuilder builder) {
return builder.messageSenders(new HttpWebServiceMessageSenderBuilder().setConnectTimeout(ofSeconds(60)).setReadTimeout(ofSeconds(60)).build()).build();
}
@Bean
public Jaxb2Marshaller jaxb2Marshaller() {
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.setContextPath("org.itrunner.ws");
return marshaller;
}
}调用Web Service：
import org.springframework.boot.webservices.client.WebServiceTemplateBuilder;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.stereotype.Service;
import org.springframework.ws.client.core.WebServiceTemplate;
@Service
public class HelloService {
private static final String DEFAULT_URI = "http://localhost:8080/HelloService";
private final WebServiceTemplate webServiceTemplate;
public HelloService(WebServiceTemplateBuilder webServiceTemplateBuilder, Jaxb2Marshaller jaxb2Marshaller) {
this.webServiceTemplate = webServiceTemplateBuilder.setDefaultUri(DEFAULT_URI)
.setMarshaller(jaxb2Marshaller).setUnmarshaller(jaxb2Marshaller).build();
}
public SayHelloResponse sayHello(SayHello request) {
return (SayHelloResponse) this.webServiceTemplate.marshalSendAndReceive(request);
}
