This post explains how to consume a soap web service with Spring Boot using org.springframework.ws.client.core.WebServiceTemplate class.
In this example, we will call Book Store web service which is already explained in the following post.
Spring Boot Soap Web Service Example
Step 1: Maven setup
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>
Step 2: To consume a web service, we need a WSDL file. Copy your WSDL file to resources folder.
src/main/resources/wsdl/books.wsdl
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"

</xs:schema>
</wsdl:types>
<wsdl:message name="getBookRequest">
<wsdl:part element="tns:getBookRequest" name="getBookRequest">

</wsdl:message>
<wsdl:message name="addBookRequest">
<wsdl:part element="tns:addBookRequest" name="addBookRequest">

</wsdl:message>
<wsdl:message name="addBookResponse">

<wsdl:binding name="BooksPortSoap11" type="tns:BooksPort">

</wsdl:binding>
<wsdl:service name="BooksPortService">
<wsdl:port binding="tns:BooksPortSoap11" name="BooksPortSoap11">
<soap:address location="http://localhost:8088/MyApp/ws" />
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
Step 3: Generate Domain classes based on Schema defined. When you run Maven build, maven-jaxb2-plugin will generate the java files and stores in target/generated-sources/xjc folder. Configure this folder as source folder in your eclipse IDE.
Step 4: Create Web Service Client Configuration class.
WebSvcClientConfig.java
package com.kswaughs.config;
import org.springframework.beans.factory.annotation.Value;
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 WebSvcClientConfig {
@Value("${books.svc.url}")
private String url;
@Bean
Jaxb2Marshaller jaxb2Marshaller() {
Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
jaxb2Marshaller.setContextPath("com.kswaughs.services.booksvc");
return jaxb2Marshaller;
}
@Bean
public WebServiceTemplate webServiceTemplate() {
WebServiceTemplate webServiceTemplate = new WebServiceTemplate();
webServiceTemplate.setMarshaller(jaxb2Marshaller());
webServiceTemplate.setUnmarshaller(jaxb2Marshaller());
webServiceTemplate.setDefaultUri(url);
return webServiceTemplate;
}
}
Step 5: Create a Service Client class which will consume the web service through above configured WebServiceTemplate class.
BookServiceClient.java
package com.kswaughs.services;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.ws.client.core.WebServiceTemplate;
import com.kswaughs.services.booksvc.AddBookRequest;
import com.kswaughs.services.booksvc.AddBookResponse;
import com.kswaughs.services.booksvc.Book;
import com.kswaughs.services.booksvc.GetBookRequest;
import com.kswaughs.services.booksvc.GetBookResponse;
import com.kswaughs.services.booksvc.ObjectFactory;
@Component
public class BookServiceClient {
private static final Logger LOGGER = LoggerFactory.getLogger(BookServiceClient.class);
@Autowired
private WebServiceTemplate webServiceTemplate;
public String addBook(String name, String author, String price) {
ObjectFactory factory = new ObjectFactory();
AddBookRequest req = factory.createAddBookRequest();
Book book = new Book();
book.setAuthor(author);
book.setName(name);
book.setPrice(price);
req.setBook(book);
LOGGER.info("Client sending book[Name={},", book.getName());
AddBookResponse resp = (AddBookResponse) webServiceTemplate.marshalSendAndReceive(req);
LOGGER.info("Client received status='{}'", resp.getStatus());
return resp.getStatus();
}
public Book getBook(String name) {
ObjectFactory factory = new ObjectFactory();
GetBookRequest req = factory.createGetBookRequest();
req.setName(name);
LOGGER.info("Client sending book[Name={},", name);
GetBookResponse resp = (GetBookResponse) webServiceTemplate.marshalSendAndReceive(req);
LOGGER.info("Client received book='{}'", resp.getBook());
return resp.getBook();
}
}
Step 6: To test this application, I am creating a sample class which will reads the user entered commands from console and calls the service client methods.
BookCommandLineListener.java
package com.kswaughs.services;
import java.util.Arrays;
import java.util.Scanner;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import com.kswaughs.services.booksvc.Book;
@Component
public class BookCommandLineListener {
private static final Logger LOGGER = LoggerFactory
.getLogger(BookCommandLineListener.class);
@Autowired
private BookServiceClient bookSvcClient;
@Scheduled(fixedDelay=1000)
public void run() throws Exception {
try (Scanner scanner = new Scanner(System.in)) {
while (true) {
LOGGER.info("Enter your command");
String text = scanner.nextLine();
LOGGER.info("you entered :{}", text);
String[] args = text.split("\\s+");
LOGGER.info("args :{}", Arrays.toString(args));
if ("ADD".equalsIgnoreCase(args[0])) {
String name = args[1];
String author = args[2];
String price = args[3];
String status = bookSvcClient.addBook(name, author, price);
LOGGER.info("Book Added Status :{}", status);
} else if ("GET".equalsIgnoreCase(args[0])) {
String name = args[1];
Book book = bookSvcClient.getBook(name);
if(book != null) {
LOGGER.info("GET Book Details : Name:{}, Author:{}, Price:{}",
book.getName(), book.getAuthor(), book.getPrice());
}
} else {
LOGGER.info("Invalid Command.");
}
}
}
}
}
Step 7: Create Spring Boot Main Application Class
SpringBootSoapServiceClientApplication.java
package com.kswaughs;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;
@SpringBootApplication
@EnableScheduling
public class SpringBootSoapServiceClientApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootSoapServiceClientApplication.class, args);
}
}
Step 8: Configure web service url in application.properties
src/main/resources/application.properties
books.svc.url=http://localhost:8088/MyApp/ws
Testing the Application
