CXF之转换工具类

本文主要是介绍CXF之转换工具类，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

        虽然webService为我们提供了很大的便利，但其也不是万能的，比方说对于Map类型的数据，它是无法处理的，这时候就需要我们进行手工处理了。在此处我们用的是转换工具类FKXmlAdapter。下面我们看具体的实现步骤：

1、用到的实体类如下：

package com.tgb.web.domain;
public class Cat {private Integer id;private String name;private String color;//get/set方法省略public Cat(){}public Cat(Integer id, String name, String color) {super();this.id = id;this.name = name;this.color = color;}  
}
public class User {private Integer id;private String name;private String pass;private String address;//get/set方法省略public User(){}public User(Integer id, String name, String pass, String address) {super();this.id = id;this.name = name;this.pass = pass;this.address = address;}@Overridepublic int hashCode() {final int prime = 31;int result = 1;result = prime * result + ((name == null) ? 0 : name.hashCode());result = prime * result + ((pass == null) ? 0 : pass.hashCode());return result;}@Overridepublic boolean equals(Object obj) {if (this == obj)return true;if (obj == null)return false;if (getClass() != obj.getClass())return false;User other = (User) obj;if (name == null) {if (other.name != null)return false;} else if (!name.equals(other.name))return false;if (pass == null) {if (other.pass != null)return false;} else if (!pass.equals(other.pass))return false;return true;}
}

2、服务层接口及其实现

1）UserService 
public interface UserService {public List<Cat> getCatsByUser(User user);//CXF无法处理该类型：Map<String, Cat>public Map<String, Cat> getAllCats();}
2）UserServiceImpl 
public class UserServiceImpl implements UserService {//用一个HashMap来模拟内存中的数据库static Map<User, List<Cat>> catDb=new HashMap<User, List<Cat>>();static{List<Cat> catList1=new ArrayList<Cat>();catList1.add(new Cat(1,"garfield","橙色"));catList1.add(new Cat(2,"机器猫","橙色"));catDb.put(new User(1,"sun","3322","花果山"), catList1);List<Cat> catList2=new ArrayList<Cat>();catList2.add(new Cat(3,"ketty","白色"));catList2.add(new Cat(4,"熊猫","白黑色"));catDb.put(new User(2,"zhu","5629","高老庄"), catList2);}@Overridepublic List<Cat> getCatsByUser(User user) {return catDb.get(user);}@Overridepublic Map<String, Cat> getAllCats() {Map<String, Cat> result=new HashMap<String, Cat>();int i=1;for (List<Cat> cats :catDb.values()){for(Cat cat:cats){result.put("第"+ i++ +"个", cat);}}return result;}
}

3、 webService接口及其实现

1）HelloWorld
@WebService
public interface HelloWorld {public String sayHi(String str);public List<Cat> getCatsByUser(User user);//此注释含义：<span style="color:#FF0000;">利用转换工具类FKXmlAdapter，将Map<String, Cat>类型转换成其他可以访问的类型值返回</span>@XmlJavaTypeAdapter(FKXmlAdapter.class)public Map<String, Cat> getAllCats();
}
2）HelloWorldWs 
@WebService(endpointInterface="com.tgb.web.webservice.HelloWorld",serviceName="HelloWorld")
public class HelloWorldWs implements HelloWorld {@Overridepublic String sayHi(String str) {return "hello,"+str+",现在时间是："+new Date();}@Overridepublic List<Cat> getCatsByUser(User user) {UserService us=new UserServiceImpl();return us.getCatsByUser(user);}@Overridepublic Map<String, Cat> getAllCats() {UserService us=new UserServiceImpl();return us.getAllCats();}
}

4、 转换工具类 FKXmlAdapter （ 该转换器负责完成StringCat与Map<String, Cat>类型之间的相互转换 ）

1）FKXmlAdapter 转换工具类
//该转换器负责完成StringCat与Map<String, Cat>类型之间的相互转换
public class FKXmlAdapter extends XmlAdapter<StringCat, Map<String, Cat>>{@Overridepublic Map<String, Cat> unmarshal(StringCat v) throws Exception {Map<String, Cat> result= new HashMap<String, Cat>();for (Entry entry:v.getEntries()) {result.put(entry.getKey(), entry.getValue());}return result;}@Overridepublic StringCat marshal(Map<String, Cat> v) throws Exception {StringCat sc=new StringCat();List<Entry> entryList=new ArrayList<StringCat.Entry>();for(String key:v.keySet()){Entry entry=new Entry();entry.setKey(key);entry.setValue(v.get(key));entryList.add(entry);}sc.setEntries(entryList);return sc;}
}
2）要转换的类型StringCat
public class StringCat {public static class Entry{private String key;private Cat value;public String getKey() {return key;}public void setKey(String key) {this.key = key;}public Cat getValue() {return value;}public void setValue(Cat value) {this.value = value;}}private List<Entry> entries;public List<Entry> getEntries() {return entries;}public void setEntries(List<Entry> entries) {this.entries = entries;} 
}

5、 发布webService

6、在浏览器中可以访问到发布的webService：http://192.168.0.72:8088/HelloWorld?wsdl

=================================================================================================================

在上面我们已经将webService的服务端写好，下面我们在客户端写测试程序来测试我们发布的服务了，如下：

public class ClientMain {public static void main(String[] args) {HelloWorld factory=new HelloWorld();com.tgb.web.webservice.HelloWorld hWorld= factory.getHelloWorldWsPort();System.out.println(hWorld.sayHi("张三"));System.out.println("===================================================");User user=new User();user.setId(30);user.setName("sun");user.setPass("3322");List<Cat> cats=hWorld.getCatsByUser(user);for(Cat cat :cats){System.out.println(cat.getName());}System.out.println("===================================================");//调用CXF处理过的类型方法StringCat SC=hWorld.getAllCats();for(Entry entry:SC.getEntries()){System.out.println(entry.getKey()+"-"+entry.getValue().getName());}}
}
