Web 服务

Spring Boot 提供 Web 服务自动配置，因此您所要做的就是定义@Endpoint bean。spring-doc.cn

Spring Web Services 功能可以通过该模块轻松访问。spring-boot-starter-webservicesspring-doc.cn

SimpleWsdl11Definition 和 SimpleXsdSchema bean 可以分别为您的 WSDL 和 XSD 自动创建。为此，请配置其位置，如以下示例所示：spring-doc.cn

Propertiesspring-doc.cn
YAMLspring-doc.cn

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

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

使用 WebServiceTemplate 调用 Web 服务

如果需要从应用程序调用远程 Web 服务，可以使用 WebServiceTemplate 类。由于WebServiceTemplate实例通常需要在使用之前进行自定义，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WebServiceTemplateBuilder，该构建器可用于在需要时创建WebServiceTemplate实例。spring-doc.cn

以下代码显示了一个典型的示例：spring-doc.cn

Javaspring-doc.cn
Kotlinspring-doc.cn

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 Classpath 上可用的 HTTP 客户端库来检测合适的基于 HTTP 的WebServiceMessageSender。您还可以为单个生成器自定义读取和连接超时，如下所示：spring-doc.cn

Javaspring-doc.cn
Kotlinspring-doc.cn

import java.time.Duration;

import org.springframework.boot.http.client.ClientHttpRequestFactorySettings;
import org.springframework.boot.webservices.client.WebServiceMessageSenderFactory;
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;

@Configuration(proxyBeanMethods = false)
public class MyWebServiceTemplateConfiguration {

	@Bean
	public WebServiceTemplate webServiceTemplate(WebServiceTemplateBuilder builder) {
		ClientHttpRequestFactorySettings settings = ClientHttpRequestFactorySettings.defaults()
			.withConnectTimeout(Duration.ofSeconds(2))
			.withReadTimeout(Duration.ofSeconds(2));
		builder.httpMessageSenderFactory(WebServiceMessageSenderFactory.http(settings));
		return builder.build();
	}

}

import org.springframework.boot.http.client.ClientHttpRequestFactorySettings
import org.springframework.boot.webservices.client.WebServiceMessageSenderFactory
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 settings = ClientHttpRequestFactorySettings.defaults()
				.withConnectTimeout(Duration.ofSeconds(2))
				.withReadTimeout(Duration.ofSeconds(2))
		builder.httpMessageSenderFactory(WebServiceMessageSenderFactory.http(settings))
		return builder.build()
	}

}

如果未应用特定的模板自定义代码，您还可以更改使用的全局 HTTP 客户端配置。
