WebService is also called XML Web
Service. WebService is a lightweight and independent communication technology that can receive requests from other systems on the Internet or Intranet. It is a software service provided on the Web through SOAP, described using a WSDL file, and registered through UDDI.
1. Remote call using HTTP+SOAP

2. IDEA generates webservice client
1.idea add webservice client module
Due to the large difference in idea versions, the functions are different, I use 2023.1
Settings - project structure
module - new module - webservice client
Choose Apache Axis as the ws engine. After selection, the code generation page may not appear. You can remove the module first, and then right-click the project
to add framework support.
The generated WebServiceTest code seems to be unusable, so change it to this:
package example;
import mypackage.ICEApiService_PortType;
import mypackage.ICEApiService_ServiceLocator;
import mypackage.ResultModel;
import java.net.MalformedURLException;
import java.net.URL;
import java.rmi.RemoteException;
public class HelloWorldClient {
public static void main(String[] argv) throws RemoteException, MalformedURLException {
ICEApiService_ServiceLocator iceApiServiceServiceLocator = new ICEApiService_ServiceLocator();
ICEApiService_PortType iceApiServiceImplPort = iceApiServiceServiceLocator.getICEApiServiceImplPort(new URL("http://IP:8808/ws/ice/api?wsdl"));
ResultModel resultModel = iceApiServiceImplPort.send_open_message_data_new("eHFz", "测试消息推送", "这是摘要！", "这是消息推送正文！！！", "0dsa4906", "0", "https://www.baidu.com/", "1234", "0", "123");
}
}
Because the generated lib package is external, it needs to be added to the project, or installed in maven before it can be used, right click "add as library"
