来自 WSDL 的 SOAP 网络服务端点 [英] SOAP webservice endpoint from WSDL
本文介绍了来自 WSDL 的 SOAP 网络服务端点的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我是 SOAP Web 服务的新手，因此参考了使用 Spring 创建 SOAP Web 服务的教程之一..我已经从看起来像这样的 xsd 创建了 wsdl.
I am new to the SOAP web service and so referenced one of the tutorial to create a SOAP webservice using Spring. . I have created the wsdl from the xsd that looks like this.
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://spring.io/guides/gs-producing-web-service"
targetNamespace="http://spring.io/guides/gs-producing-web-service" elementFormDefault="qualified">
<xs:element name="getCountryRequest">
<xs:complexType>
<xs:sequence>
<xs:element name="name" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="getCountryResponse">
<xs:complexType>
<xs:sequence>
<xs:element name="country" type="tns:country"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:complexType name="country">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="population" type="xs:int"/>
<xs:element name="capital" type="xs:string"/>
<xs:element name="currency" type="tns:currency"/>
</xs:sequence>
</xs:complexType>
<xs:simpleType name="currency">
<xs:restriction base="xs:string">
<xs:enumeration value="GBP"/>
<xs:enumeration value="EUR"/>
<xs:enumeration value="PLN"/>
</xs:restriction>
</xs:simpleType>
</xs:schema>
我还在下面创建了服务端点.
I have also created the service endpoint below.
package hello;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ws.server.endpoint.annotation.Endpoint;
import org.springframework.ws.server.endpoint.annotation.PayloadRoot;
import org.springframework.ws.server.endpoint.annotation.RequestPayload;
import org.springframework.ws.server.endpoint.annotation.ResponsePayload;
import io.spring.guides.gs_producing_web_service.GetCountryRequest;
import io.spring.guides.gs_producing_web_service.GetCountryResponse;
@Endpoint
public class CountryEndpoint {
private static final String NAMESPACE_URI = "http://spring.io/guides/gs-producing-web-service";
private CountryRepository countryRepository;
@Autowired
public CountryEndpoint(CountryRepository countryRepository) {
this.countryRepository = countryRepository;
}
@PayloadRoot(namespace = NAMESPACE_URI, localPart = "getCountryRequest")
@ResponsePayload
public GetCountryResponse getCountry(
@RequestPayload GetCountryRequest request) {
GetCountryResponse response = new GetCountryResponse();
response.setCountry(countryRepository.findCountry(request.getName()));
return response;
}
}
并像这样配置bean.
And configured the bean like this.
package hello;
import org.springframework.boot.context.embedded.ServletRegistrationBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.ws.config.annotation.EnableWs;
import org.springframework.ws.config.annotation.WsConfigurerAdapter;
import org.springframework.ws.transport.http.MessageDispatcherServlet;
import org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition;
import org.springframework.xml.xsd.SimpleXsdSchema;
import org.springframework.xml.xsd.XsdSchema;
@EnableWs
@Configuration
public class WebServiceConfig extends WsConfigurerAdapter {
@Bean
public ServletRegistrationBean dispatcherServlet(ApplicationContext applicationContext) {
MessageDispatcherServlet servlet = new MessageDispatcherServlet();
servlet.setApplicationContext(applicationContext);
servlet.setTransformWsdlLocations(true);
return new ServletRegistrationBean(servlet, "/ws/*");
}
@Bean(name = "countries")
public DefaultWsdl11Definition defaultWsdl11Definition(XsdSchema countriesSchema) {
DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
wsdl11Definition.setPortTypeName("CountriesPort");
wsdl11Definition.setLocationUri("http://localhost:8080/Demo2-0.0.1-SNAPSHOT/ws/");
wsdl11Definition.setTargetNamespace("http://spring.io/guides/gs-producing-web-service");
wsdl11Definition.setSchema(countriesSchema);
return wsdl11Definition;
}
@Bean
public XsdSchema countriesSchema() {
return new SimpleXsdSchema(new ClassPathResource("countries.xsd"));
}
}
将 WAR 文件部署到 tomcat 服务器后，我可以在 http://localhost:8080/Demo2-0.0.1-SNAPSHOT/ws/countries.wsdl 看到 WSDL，它看起来像这个.
After deploying the WAR file into tomcat server i am able to see the WSDL at http://localhost:8080/Demo2-0.0.1-SNAPSHOT/ws/countries.wsdl which looks like this.

我能够在服务器上看到 WSDL，但无法找到发送 SOAP 请求的服务端点.我参考了几个教程，但无法找出端点.点击 http://localhost:8080/Demo2-0.0.1-SNAPSHOT/ws/ 返回 405 错误.请帮我解决这个问题.
I am able to see the WSDLon the server but unable to find the service endpoint to send the SOAP request. I refereed several tutorials but was unable to figure out the endpoint. Hitting at http://localhost:8080/Demo2-0.0.1-SNAPSHOT/ws/ returns a 405 error. Please help me out on this.
推荐答案
使用浏览器(即通过 GET)访问 SOAP 服务时获取 405(方法不允许)错误代码实际上是正确的行为:所有 SOAP HTTP 访问是通过 POST 而不是 GET 完成的.
Getting a 405 (Method not Allowed) error code when accessing a SOAP service with a browser (i.e. via a GET) is actually correct behavior: all SOAP HTTP access is done via a POST, not a GET.
您可以尝试将 SOAP 客户端指向 WSDL(例如 SoapUI)，然后看看是否可行.
You can try pointing a SOAP client at the WSDL ( SoapUI for example), and see if that works instead.
