Web 服务

Spring Boot 提供 Web 服务自动配置，因此你只需定义你的端点。

可以使用spring-boot-starter-webservices模块轻松访问Spring Web Services功能。

可以自动为您的WSDL和XSD分别创建SimpleWsdl11Definition和SimpleXsdSchema bean。为此，请配置它们的位置，如下例所示

属性
YAML

spring.webservices.wsdl-locations=classpath:/wsdl

spring:
  webservices:
    wsdl-locations: "classpath:/wsdl"

使用WebServiceTemplate调用Web服务

如果您需要从您的应用程序调用远程Web服务，您可以使用WebServiceTemplate类。由于WebServiceTemplate实例通常需要在使用前进行自定义，因此Spring Boot不提供任何单个自动配置的WebServiceTemplate bean。但是，它确实会自动配置一个WebServiceTemplateBuilder，可以在需要时使用它来创建WebServiceTemplate实例。

以下代码显示了一个典型的示例

Java
Kotlin

import org.springframework.boot.webservices.client.WebServiceTemplateBuilder;
import org.springframework.stereotype.Service;
import org.springframework.ws.client.core.WebServiceTemplate;
import org.springframework.ws.soap.client.core.SoapActionCallback;

@Service
public class MyService {

	private final WebServiceTemplate webServiceTemplate;

	public MyService(WebServiceTemplateBuilder webServiceTemplateBuilder) {
		this.webServiceTemplate = webServiceTemplateBuilder.build();
	}

	public SomeResponse someWsCall(SomeRequest detailsReq) {
		return (SomeResponse) this.webServiceTemplate.marshalSendAndReceive(detailsReq,
				new SoapActionCallback("https://ws.example.com/action"));
	}

}

import org.springframework.boot.webservices.client.WebServiceTemplateBuilder
import org.springframework.stereotype.Service
import org.springframework.ws.client.core.WebServiceTemplate
import org.springframework.ws.soap.client.core.SoapActionCallback

@Service
class MyService(webServiceTemplateBuilder: WebServiceTemplateBuilder) {

	private val webServiceTemplate: WebServiceTemplate

	init {
		webServiceTemplate = webServiceTemplateBuilder.build()
	}

	fun someWsCall(detailsReq: SomeRequest?): SomeResponse {
		return webServiceTemplate.marshalSendAndReceive(
			detailsReq,
			SoapActionCallback("https://ws.example.com/action")
		) as SomeResponse
	}

}

默认情况下，WebServiceTemplateBuilder使用类路径上可用的HTTP客户端库检测合适的基于HTTP的WebServiceMessageSender。您还可以自定义读取和连接超时，如下所示

Java
Kotlin

import java.time.Duration;

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.ws.client.core.WebServiceTemplate;
import org.springframework.ws.transport.WebServiceMessageSender;

@Configuration(proxyBeanMethods = false)
public class MyWebServiceTemplateConfiguration {

	@Bean
	public WebServiceTemplate webServiceTemplate(WebServiceTemplateBuilder builder) {
		WebServiceMessageSender sender = new HttpWebServiceMessageSenderBuilder()
				.setConnectTimeout(Duration.ofSeconds(5))
				.setReadTimeout(Duration.ofSeconds(2))
				.build();
		return builder.messageSenders(sender).build();
	}

}

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.ws.client.core.WebServiceTemplate
import java.time.Duration

@Configuration(proxyBeanMethods = false)
class MyWebServiceTemplateConfiguration {

	@Bean
	fun webServiceTemplate(builder: WebServiceTemplateBuilder): WebServiceTemplate {
		val sender = HttpWebServiceMessageSenderBuilder()
			.setConnectTimeout(Duration.ofSeconds(5))
			.setReadTimeout(Duration.ofSeconds(2))
			.build()
		return builder.messageSenders(sender).build()
	}

}
