Written in front:

There are many methods and frameworks for developing webservices, such as cxf, etc., but these must use the annotation function when you write service classes. If the current jdk is 1.4, then the annotation function cannot be used. So the axis tool can be used here.

1. Required jar package:

2. Generally, webservice is used in web projects at work, so when creating a web project, The required jar package is placed in the lib directory

3. In the web.xml file, add

<servlet>
    <servlet-name>AxisServlet</servlet-name>
    <servlet-class>org.apache.axis.transport.http.AxisServlet</servlet-class>
  </servlet>
  <!-- 这里是访问服务的路径 -->
  <servlet-mapping>
    <servlet-name>AxisServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
  </servlet-mapping>

Copy after login

4. Create a service class, an interface, and an implementation class That’s it, first the interface

package edu.hue.server;public interface SayHello {public String say(String name);
}

Copy after login

Then the implementation class of the interface

package edu.hue.server;public class SayHelloImpl implements SayHello{public String say(String name) {return "Hello my friend " + name;
    }

}

Copy after login

5. Create it below WEB-INF server-config.wsdd (Create this file directly, then copy the following code, and then add your own service configuration as needed. In fact, this file can be generated by yourself. You need to create a deploy.wsdd yourself to start the project. After running, server-config.wsdd will be automatically generated. For convenience, the process is omitted here. You only need to add your own service to server-config.wsdd. Learn how to use it first)

Copy after login

Parameter explanation: name: a name for the service here is called sayHello, and then the following value="Fill in here is the full path of the implementation class of your service", almost these two parameters need to be changed, the others Just copy it

6. Run the project, enter in the browser: localhost:8080/test_axis3_stub/services, press Enter, and you can access it.

Localhost:8080/test_axis3_stub (project name)/services (the service access path is configured in web.xml to intercept /services/*, so you only need to enter services here to access)

What is mentioned here is a simple introduction. If it involves complex parameters, such as the transfer of beans, you need to study it further. (It seems that you also need to make relevant configurations when configuring the service in server-config.wsdd)
