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;    }    @Override    public 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;    }    @Override    public 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);    }        @Override    public List<Cat> getCatsByUser(User user) {        return catDb.get(user);    }    @Override    public 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@WebServicepublic 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 {    @Override    public String sayHi(String str) {        return "hello,"+str+",现在时间是："+new Date();    }        @Override    public List<Cat> getCatsByUser(User user) {        UserService us=new UserServiceImpl();                return us.getCatsByUser(user);    }            @Override    public 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>>{    @Override    public 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;    }    @Override    public 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StringCatpublic 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

public class ServerMain {

public static void main(String[] args) {

HelloWorld hw=new HelloWorldWs();

//调用Endpoint的publish方法发布Web Service

Endpoint.publish("http://192.168.0.72:8088/HelloWorld", hw);

System.out.println("webService 发布成功！");

}

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());        }    }}
