1.写一个接口和实现

package com.java1234.webservice;

import java.util.List;

import javax.jws.WebService;

import com.java1234.entity.Role;
import com.java1234.entity.User;

@WebService   //注意这里
public interface HelloWorld {

    public String say(String str);
    
    public List<Role> getRoleByUser(User user);
}

package com.java1234.webservice.impl;

import java.util.ArrayList;
import java.util.List;

import javax.jws.WebService;

import com.java1234.entity.Role;
import com.java1234.entity.User;
import com.java1234.webservice.HelloWorld;

@WebService   //注意这里
public class HelloWorldImpl implements HelloWorld{

    public String say(String str) {
        return "Hello:"+str;
    }

    public List<Role> getRoleByUser(User user) {
        List<Role> roleList=new ArrayList<Role>();
        // 模拟  直接写死
        if(user!=null){
            if(user.getUserName().equals("java1234") && user.getPassword().equals("123456")){
                roleList.add(new Role(1,"技术总监"));
                roleList.add(new Role(2,"架构师"));
            }else if(user.getUserName().equals("jack") && user.getPassword().equals("123456")){
                roleList.add(new Role(3,"程序员"));
            }
            return roleList;
        }else{
            return null;
        }
    }

}



package com.java1234.webservice.impl;





import javax.xml.ws.Endpoint;

import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

import com.java1234.webservice.HelloWorld;

public class Server {

    public static void main(String[] args) {
        System.out.println("web service start");
        HelloWorld implementor=new HelloWorldImpl();
        String address="http://192.168.244.1/helloWorld";
         Endpoint.publish(address, implementor); // jdk实现 暴露webservice接口
        
        System.out.println("web service started");
    }
}

运行结果是:

访问: http://192.168.244.1/helloWorld?wsdl
