Web Services

Spring Boot 提供 Web Services 自动配置,因此你只需定义你的 @Endpoint bean 即可。

通过 Spring Web Services 功能 可以轻松访问 spring-boot-starter-webservices 模块。

可以为你的 WSDL 和 XSD 自动创建 SimpleWsdl11DefinitionSimpleXsdSchema 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 Services

如果你的应用程序需要调用远程 Web Services,你可以使用 WebServiceTemplate 类。由于 WebServiceTemplate 实例在使用前通常需要自定义,Spring Boot 不提供任何单一的自动配置 WebServiceTemplate bean。但是,它会自动配置一个 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。你也可以如下所示为单个构建器自定义读取和连接超时时间

  • Java

  • Kotlin

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,你还可以更改所使用的 全局 HTTP 客户端配置
