我写了一个简单的SOAP端点,主要是按照这里的Spring教程:https://spring.io/guides/gs/producing-web-service/
下面是用于拦截请求的类(假设注入了存储库对象):
@Endpoint
public class SampleEndpoint {
@PayloadRoot(namespace = NAMESPACE_URI, localPart = "SampleRequest")
public
@ResponsePayload
JAXBElement<SampleResponseType> sampleQuery(
@RequestPayload JAXBElement<SampleRequestType> request) {
ObjectFactory factory = new ObjectFactory();
SampleResponseType response = repository.query(request.getValue());
JAXBElement<SampleResponseType> jaxbResponse = factory.createSampleResponse(response);
return jaxbResponse;
}
}
该服务正确执行。我遇到的一个问题是性能,尤其是在解组响应时。平均而言,将对象解组为XML响应需要几秒钟。有没有办法缓存/注入JaxbContext Spring正在使用这个过程来改进这个时间?
这是我用于此端点的Web服务配置文件。我曾尝试在Saaj和Axiom消息工厂之间进行交替,但没有看到很多性能变化:
@EnableWs
@Configuration
public class WebServiceConfig extends WsConfigurerAdapter {
@Bean
public SaajSoapMessageFactory soap12MessageFactory() {
SaajSoapMessageFactory factory = new SaajSoapMessageFactory();
factory.setSoapVersion(SoapVersion.SOAP_12);
return factory;
}
@Bean
public AxiomSoapMessageFactory axiomSoapMessageFactory() {
AxiomSoapMessageFactory factory = new AxiomSoapMessageFactory();
factory.setSoapVersion(SoapVersion.SOAP_12);
factory.setPayloadCaching(false);
return factory;
}
@Bean
public ServletRegistrationBean dispatcherServlet(
ApplicationContext applicationContext) {
MessageDispatcherServlet servlet = new MessageDispatcherServlet();
servlet.setApplicationContext(applicationContext);
servlet.setTransformWsdlLocations(true);
servlet.setMessageFactoryBeanName("soap12MessageFactory");
return new ServletRegistrationBean(servlet, "/ws/*");
}
@Bean(name = "wsdlname")
public DefaultWsdl11Definition xcpdDefaultXcpdWsdl11Definition(XsdSchema
schema) {
DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
wsdl11Definition.setCreateSoap11Binding(false);
wsdl11Definition.setCreateSoap12Binding(true);
wsdl11Definition.setPortTypeName("xcpdPort");
wsdl11Definition.setLocationUri("/ws");
wsdl11Definition
.setTargetNamespace("http://somenamespace.org/");
wsdl11Definition.setSchema(schema);
return wsdl11Definition;
}
@Bean
public XsdSchema schema() {
return new SimpleXsdSchema(
new ClassPathResource(
"schema.xsd"));
}
}

我们两天前就解决了这个问题。我们看到的第一个问题是JVM的客户端版本安装在服务器上。我安装了JVM的服务器版本并更改了Tomcat以使用该实例。一些Web服务的性能得到了显着改善。以前简单的请求需要三秒钟,现在它们需要250毫秒。但是在测试我写的Spring服务时,我没有看到太多改进。
为解决上一个问题,我在Tomcat的Java选项中添加了以下内容:
-Dcom.sun.xml.internal.bind.v2.runtime.JAXBContextImpl.fastBoot=true
重新启动Tomcat实例后,服务的响应时间现在都低于一秒。之前的请求最多需要30秒才能完成。我们使用的服务器JRE如下:
