If I would like to consume a web service which provide by http://localhost:8080/ws/eaWs.wsdl
How to create SOAP client to consume web services?
How-To
1. Generate Java classes via SoapUI and save WSDL file into resources/wsdl
2. Create WsClientConfig class:
package com.example.soapClient.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.oxm.jaxb.Jaxb2Marshaller; import org.springframework.ws.client.core.WebServiceTemplate; @Configuration public class WsClientConfig { private String defaultUri = "http://localhost:8080/ws/eaWs"; @Bean public Jaxb2Marshaller jaxb2Marshaller() { Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller(); jaxb2Marshaller.setContextPaths("ws.oi2.npa.ea.country", "ws.oi2.npa.ea.emp"); return jaxb2Marshaller; } @Bean public WebServiceTemplate webServiceTemplate() { WebServiceTemplate webServiceTemplate = new WebServiceTemplate(); webServiceTemplate.setMarshaller(jaxb2Marshaller()); webServiceTemplate.setUnmarshaller(jaxb2Marshaller()); webServiceTemplate.setDefaultUri(defaultUri); return webServiceTemplate; } }
3. Create Country Client Class
package com.example.soapClient.client; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import org.springframework.ws.client.core.WebServiceTemplate; import ws.oi2.npa.ea.country.Country; import ws.oi2.npa.ea.country.GetCountryRequest; import ws.oi2.npa.ea.country.GetCountryResponse; @Component public class CountryClient { @Autowired private WebServiceTemplate webServiceTemplate; public void getCountry(String name) { GetCountryRequest request = new GetCountryRequest(); request.setName(name); GetCountryResponse response = (GetCountryResponse) webServiceTemplate.marshalSendAndReceive(request); Country country = response.getCountry(); System.out.println("[getCountry] name = " + country.getName() + ", capital = " + country.getCapital()); } }
4. Create Employee Client Class
package com.example.soapClient.client; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import org.springframework.ws.client.core.WebServiceTemplate; import ws.oi2.npa.ea.emp.Employee; import ws.oi2.npa.ea.emp.GetEmployeeByIdRequest; import ws.oi2.npa.ea.emp.GetEmployeeRequest; import ws.oi2.npa.ea.emp.GetEmployeeResponse; @Component public class EmployeeClient { @Autowired private WebServiceTemplate webServiceTemplate; public void getEmployeeByName(String name) { GetEmployeeRequest request = new GetEmployeeRequest(); request.setName(name); GetEmployeeResponse response = (GetEmployeeResponse) webServiceTemplate.marshalSendAndReceive(request); Employee employee = response.getEmployee(); System.out.println("[getEmployeeByName] id = " + employee.getId() + ", name = " + employee.getName()); } public void getEmployeeById(Integer id) { GetEmployeeByIdRequest request = new GetEmployeeByIdRequest(); request.setId(id); GetEmployeeResponse response = (GetEmployeeResponse) webServiceTemplate.marshalSendAndReceive(request); Employee employee = response.getEmployee(); System.out.println("[getEmployeeById] id = " + employee.getId() + ", name = " + employee.getName()); } }
5. Do test
package com.example.soapClient; import org.springframework.boot.CommandLineRunner; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.Bean; import com.example.soapClient.client.CountryClient; import com.example.soapClient.client.EmployeeClient; @SpringBootApplication public class SoapClientApplication { public static void main(String[] args) { SpringApplication.run(SoapClientApplication.class, args); } @Bean CommandLineRunner test(CountryClient cClient, EmployeeClient eClient) { return args -> { cClient.getCountry("台灣"); eClient.getEmployeeById(1); eClient.getEmployeeByName("Mandy"); }; } }
Test result:
[getCountry] name = 台灣, capital = 台北 [getEmployeeById] id = 1, name = Albert [getEmployeeByName] id = 2, name = Mandy
