自定义webService

Posted 2020-10-01 popcorn丫

要生成一个wsdl,首先要有一个ws，建立一个简单的ws

package com.bxw.server;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.xml.ws.Endpoint;

/*
 *  自定义ws服务, jdk1.6版本仅仅支持 soap1.1格式,jdk1.7及以上版本支持 soap1.2格式
 *  发布ws服务只需要@WebService注解即可, 如果想要更好的可维护性,则可以通过注解来实现
 * */
@WebService // 默认静态的方式是不能发布ws服务的
(
        name="MyWebService1",  // 服务实现类的名称
        serviceName="MyWebServiceService1",  // 默认在发布的服务实现者的名称后面添加Service
        portName="MyWebServicePort1",   // 服务类型的名称: 默认在 发布的服务实现者(MyWebService) 后面添加 port
        targetNamespace="com.bxw.ws"    // 发布ws服务的命名空间,此空间默认为当前服务包路径的 "倒写"此名称也是 wsimport 命令生成 java类时默认的包路径 -p
)
public class WebService1 {
    
    @WebMethod(exclude=true)  // 默认public方法可以发布为ws服务, 如果要排除则配置  exclude=true
    public String saySth(String text){
        return "say"+text;
    }
    
    //可以指定wsdl中的方法名，参数名和返回值
    @WebMethod(operationName="saySth")
    public @WebResult(name="result") String saySth(@WebParam(name="text") String text,@WebParam(name="age") String age){
        return "say "+text+"|| age "+age;
    }
    public static void main(String[] args) {
        String address = "http://localhost:9090/ws";
        Endpoint.publish(address, new WebService1());
        System.out.println("访问wsdl的地址："+address+"?WSDL");
    }
}

要创建一个ws，只需要添加@webService注解即可。其余注解用法已写在注释中。运行后，访问服务发布的地址：http://localhost:9090/ws?wsdl

之后创建客户端：

cmd运行wsimport命令后，将生成的java文件copy至客户端项目中。

package com.bxw.client;

import java.net.MalformedURLException;
import java.net.URL;

import com.bxw.ws.MyWebService1;
import com.bxw.ws.MyWebServiceService1;

public class WebClient {
    public static void main(String[] args) throws MalformedURLException {
        URL url = new URL("http://localhost:9090/ws?WSDL");
        MyWebServiceService1 service = new MyWebServiceService1(url);
        MyWebService1 ss = service.getMyWebServicePort1();
        System.out.println(ss.saySth("a", "1"));
    }
}

url可以在配置文件中配置，以防路径改变。

 

================================分割线========================================

cxf中使用map:

实体：

package com.bxw.entity;

public class User {
    private String id;
    private String username;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    
    
}

package com.bxw.entity;

public class Role {
    private String id;
    private String roleName;
    
    public Role() {
    }

    public Role(String id,String roleName){
        this.id = id;
        this.roleName = roleName;
    }
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getRoleName() {
        return roleName;
    }
    public void setRoleName(String roleName) {
        this.roleName = roleName;
    }
    
    
}

 

service:

package com.bxw.service;

import java.util.List;
import java.util.Map;

import javax.jws.WebService;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;

import com.bxw.entity.MapAdapter;
import com.bxw.entity.Role;
import com.bxw.entity.User;

@WebService
public interface Service {

    public List<Role> getRole(User user);
        
    @XmlJavaTypeAdapter(MapAdapter.class)
    public Map<String, List<Role>> getRoles();
}

注意@XmlJavaTypeAdapter(MapAdapter.class)这里返回的map类型需要自己编写一个转换器转换。

mapAdapter:

 

package com.bxw.entity;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.xml.bind.annotation.adapters.XmlAdapter;


/**
 * Map适配器
 * @author Administrator
 *
 */
public class MapAdapter extends XmlAdapter<MyRole[], Map<String,List<Role>>>{

    /**
     * 适配转换  MyRole[] -> Map<String, List<Role>>
     */
    @Override
    public Map<String, List<Role>> unmarshal(MyRole[] v) throws Exception {
        Map<String, List<Role>> map=new HashMap<String,List<Role>>();
        for(int i=0;i<v.length;i++){
            MyRole r=v[i];
            map.put(r.getKey(), r.getValue());
        }
        return map;
    }

    /**
     * 适配转换  Map<String, List<Role>> -> MyRole[]
     */
    @Override
    public MyRole[] marshal(Map<String, List<Role>> v) throws Exception {
        MyRole[] roles=new MyRole[v.size()];
        int i=0;
        for(String key:v.keySet()){
            roles[i]=new MyRole();
            roles[i].setKey(key);
            roles[i].setValue(v.get(key));
            i++;
        }
        return roles;
    }
}

 

将map转换为自定义的MyRole数组类型:

MyRole:

package com.bxw.entity;

import java.util.List;


/**
 * 自定义实体 cxf能接受
 * @author Administrator
 *
 */
public class MyRole {

    private String key;
    private List<Role> value;
    
    public String getKey() {
        return key;
    }
    public void setKey(String key) {
        this.key = key;
    }
    public List<Role> getValue() {
        return value;
    }
    public void setValue(List<Role> value) {
        this.value = value;
    }
    
    
}

 

impl:

package com.bxw.service.impl;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.jws.WebService;

import com.bxw.entity.Role;
import com.bxw.entity.User;
import com.bxw.service.Service;

@WebService
public class ServiceImpl implements Service{

    public List<Role> getRole(User user) {
        List<Role> ls = new ArrayList<Role>();
        ls.add(new Role(user.getId(), "admin"));
        return ls;
    }
    
    public Map<String, List<Role>> getRoles() {
        Map<String, List<Role>> map = new HashMap<String, List<Role>>();
        List<Role> ls = new ArrayList<Role>();
        ls.add(new Role("1","admin"));
        ls.add(new Role("2","customer"));
        map.put("key", ls);
        return map;
    }

}

 

 

Test:

package com.bxw.test;

import javax.xml.ws.Endpoint;

import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

import com.bxw.service.Service;
import com.bxw.service.impl.ServiceImpl;


public class Test {
    public static void main(String[] args) {
        System.out.println("web service start");  
        Service implementor = new ServiceImpl();  
        String address = "http://localhost:9095/helloWorld";  
         Endpoint.publish(address, implementor);  // JDK实现
         
//       JaxWsServerFactoryBean factoryBean = new JaxWsServerFactoryBean();
//       factoryBean.setAddress(address); // 设置暴露地址
//       factoryBean.setServiceClass(Service.class); // 接口类
//       factoryBean.setServiceBean(implementor); // 设置实现类
//       factoryBean.create();    
    }
}
