How to use WSDL with spring-boot?

问题

I have WSDL and schema files provided by client. I need to create Spring-boot SOAP web service with this WSDL file. I have google it and all the examples that I can find, they have auto-generate the wsdl with spring.How can I use my WSDL to generate the SOAP service?

回答1:

Here are the common steps to follow to use your existing wsdl with Spring-Ws and Spring-boot.

Config class

@EnableWs
@Configuration
public class WebServiceConfig extends WsConfigurerAdapter {
    @Bean
    public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
        MessageDispatcherServlet servlet = new MessageDispatcherServlet();
        servlet.setApplicationContext(applicationContext);
        servlet.setTransformWsdlLocations(true);
        return new ServletRegistrationBean(servlet, "/ws/*");
    }

    //http://localhost:8080/ws/services.wsdl --bean name is set to 'services'
    @Bean(name = "services")
    public Wsdl11Definition defaultWsdl11Definition() {
        SimpleWsdl11Definition wsdl11Definition = new SimpleWsdl11Definition();
        wsdl11Definition.setWsdl(new ClassPathResource("/schema/MyWsdl.wsdl")); //your wsdl location
        return wsdl11Definition;
    }
}

In your pom.xml use 'jaxb2-maven-plugin' plugin to generate classes from your wsdl.
In Spring-WS, you have to write endpoint yourself. No code generation for endpoints. Its easy to write. you can follow tutorial/guide on spring website.

There are a number of options for exposing a web service starting from a WSDL file and using Spring Boot. You would typically generate your Java classes from the WSDL definition. There are a number of JAXB Maven plugins that will support you in doing this.

In addition when using Spring Boot make sure you take advantage of the spring-boot-starters in order to automatically manage the different needed dependencies.

One approach is to use Spring Web Services in combination with the maven-jaxb2-plugin plugin. I've created a step by step tutorial which explains how to do this using Spring-WS starting from a WSDL file for both consumer and provider.

Another alternative is to use a framework like Apache CXF in combination with the cxf-codegen-plugin plugin. CXF also comes with it's own CXF Spring Boot starter called cxf-spring-boot-starter-jaxws. In order to get you started I've compiled an example which uses the CXF starter in combination with Spring Boot to create a web service starting from a WSDL file.

You can create WebServiceConfiguration java class in your packages.

@EnableWs
@Configuration
public class WebServiceConfig extends WsConfigurerAdapter {

    @Bean
    public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
        MessageDispatcherServlet servlet = new MessageDispatcherServlet();
        servlet.setApplicationContext(applicationContext);
        servlet.setTransformWsdlLocations(true);
        return new ServletRegistrationBean(servlet, "/ProjectName/*");
    }
    @Bean(name = "wsdlname")
    public DefaultWsdl11Definition defaultWsdl11Definition (XsdSchema cityRequestSchema) {
        DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
        wsdl11Definition.setRequestSuffix("ByCountry");
        wsdl11Definition.setResponseSuffix("City");
        wsdl11Definition.setPortTypeName("Hotelport");
        wsdl11Definition.setLocationUri("/ProjectName");
        wsdl11Definition.setTargetNamespace("http://spring.io/guides/gs-producing-web-service");
        wsdl11Definition.setSchema(cityRequestSchema);
        return wsdl11Definition;

    }

    @Bean
public XsdSchema cityRequestSchema() {
    return new SimpleXsdSchema(new ClassPathResource("CityRequest.xsd"));
}

After run as spring boot app...then copy paste this url in your browser. http://localhost:8080/ProjectName/wsdlname.wsdl

noted:localhost:8080 to replace with your tomcat port

The easiest way is to simply use the cxf-spring-boot-starter incl. it's companion Maven plugin, they will take care of generating mostly everything needed from your wsdl and schema files. Here's a full example: https://github.com/codecentric/spring-samples/tree/master/cxf-boot-simple.

Using the starter in your pom.xml, you just have to place the wsdl & schema files in src/main/resources and you're mostly done. Here's a full example pom.xml:
