WebService

WebService是一种跨编程语言和跨操作系统平台的远程调用技术
XML+XSD,SOAP和WSDL就是构成WebService平台的三大技术

目录结构

将wsdl文档放入resources.wsdl中（或者在maven中配置wsdl url）
其中wdsl.message和wdsl.voice是相应生成的模板类

目录结构

pom.xml

通过maven插件jaxb2生成模板类

configbean配置

@Configuration
public class WebServiceConfig {
    @Bean
    public Jaxb2Marshaller marshaller() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        // this is the package name specified in the <generatePackage> specified in pom.xml
        marshaller.setContextPath("com.example.consumingwebservice.wsdl.voice");
        return marshaller;
    }

    @Bean
    public WebServiceClient soapConnector(Jaxb2Marshaller marshaller) {
        WebServiceClient client = new WebServiceClient();
        client.setMarshaller(marshaller);
        client.setUnmarshaller(marshaller);
        return client;
    }

}

public class WebServiceClient extends WebServiceGatewaySupport {

    public Object callWebService(String url, Object request, String callbackUrl){
        return getWebServiceTemplate().marshalSendAndReceive(url, request, new SoapActionCallback(callbackUrl));
    }
}

使用

@SpringBootTest
class SendMessageTests {

    @Autowired
    private WebServiceClient callClient;

    @Test
    void test() throws DatatypeConfigurationException {
        //SendMessage是生成的模板类请求参数
        SendMessage request = new SendMessage();
        //设置参数 略
        request.setContent("测试3");
        //webservice地址
        String url = "xxx";
        //callback是回调地址，将请求结果返回；即soapAction地址
        String callback = "xxx";
        SendMessageResponse response = (SendMessageResponse) callClient.callWebService(url,request,callback);
        System.out.println(response.getSendMessageResult().isSuccess());
        System.out.println(response.getSendMessageResult().getResult());
        System.out.println(response.getSendMessageResult().getMessage());
    }

}
