WS之cxf处理的复杂类型(Map)

一、服务端:

  1、创建接口:

package cn.tdtk.ws.dao;

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

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

import cn.tdtk.ws.domain.Cat;
import cn.tdtk.ws.domain.Horse;
import cn.tdtk.ws.domain.User;
import cn.tdtk.ws.util.FkXmlAdapter;

/** @WebService 所修饰的接口,那么接口里面的方法全部都属于web的服务 */
@WebService
public interface HelloWorld {
  //基本数据类型都可以CXF进行实习
  String sayHello(String name);

  //复杂数据类型
  List<Cat> getCatsByUser(User user);

  /** CXF不能处理Map<String,Cat>类型,于是采用FkXmlAdapter进行处理。*/
  @XmlJavaTypeAdapter(FkXmlAdapter.class)Map<String,Cat> getAllCats();

  Horse selectMaxLongName(Horse h1,Horse h2);
}

  2、实现接口:

  

package cn.tdtk.ws.dao.impl;

import java.io.File;
import java.util.Date;
import java.util.List;
import java.util.Map;

import javax.activation.DataHandler;
import javax.activation.FileDataSource;

import cn.tdtk.ws.dao.HelloWorld;
import cn.tdtk.ws.dao.UserService;
import cn.tdtk.ws.domain.Cat;
import cn.tdtk.ws.domain.Horse;
import cn.tdtk.ws.domain.User;

public class HelloWorldImpl implements HelloWorld {

  @Override
  public String sayHello(String name) {
    return name + ",你好,现在的时间是: "+new Date();
  }

  @Override
  public List<Cat> getCatsByUser(User user) {
    // 在这里只是调用业务逻辑组件,而不实现,具体的实现由业务类去完成

    UserService us = new UserServiceImpl();
    return us.getCatsByUser(user);
  }

  @Override
  public Map<String, Cat> getAllCats() {
    UserService us = new UserServiceImpl();
    return us.getAllCats();
  }

  @Override
  public Horse selectMaxLongName(Horse h1, Horse h2) {
    if(h1.getName().length()>h2.getName().length())
      return h1;
    else{
        h2.setImage(new DataHandler(new FileDataSource(
          new File("c:\\"+File.separator+"1.jpg"))));
        return h2;
    }
  }

}

  3、将Map类型与简单类型互相转换:

package cn.tdtk.ws.util;

import java.util.List;

import cn.tdtk.ws.domain.Cat;

public class StringCat {

public static class Entry {
private String key;
private Cat value;
public Entry() {
super();
}

public Entry(String key, Cat value) {
super();
this.key = key;
this.value = 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> entrys;

public List<Entry> getEntrys() {
return entrys;
}

public void setEntrys(List<Entry> entrys) {
this.entrys = entrys;
}

}

  4、XmlAdapter转换器:

package cn.tdtk.ws.util;

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

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

import cn.tdtk.ws.domain.Cat;
import cn.tdtk.ws.util.StringCat.Entry;

/**
* 该转换器负责 StringCat 和 Map<String, Cat> 类型的转换
* @author Administrator
*
*/
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>();
    List<Entry> entrys = v.getEntrys();
    for(Entry en : entrys)
      result.put(en.getKey(), en.getValue());
    return result;
}

@Override
public StringCat marshal(Map<String, Cat> v) throws Exception {

  StringCat sc = new StringCat();
  List<Entry> entrys = new ArrayList<Entry>();
  for(String key : v.keySet())
    entrys.add(new Entry(key,v.get(key)));
  sc.setEntrys(entrys);
  return sc;
  }

}

  5、业务数据:

package cn.tdtk.ws.dao.impl;

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

import cn.tdtk.ws.dao.UserService;
import cn.tdtk.ws.domain.Cat;
import cn.tdtk.ws.domain.User;

public class UserServiceImpl implements UserService {

static Map<User,List<Cat>> catDb = new HashMap<User,List<Cat>>();
static{
List<Cat> catlist1= new ArrayList<Cat>();
catlist1.add(new Cat(1,"机器猫","橙色"));
catlist1.add(new Cat(2,"huanhuan","黑色"));
catlist1.add(new Cat(3,"xixi","红色"));
catDb.put(new User(1,"tom","123","shanghai"), catlist1);

List<Cat> catlist2= new ArrayList<Cat>();
catlist2.add(new Cat(1,"lulu","橙色"));
catlist2.add(new Cat(2,"haha","黑色"));
catDb.put(new User(1,"lili","123","shanghai"), catlist2);
}

@Override
public List<Cat> getCatsByUser(User user) {
return catDb.get(user);
}

@Override
public Map<String, Cat> getAllCats() {
Map<String, Cat> maps = new HashMap<String, Cat>();
int i=0;
for(List<Cat> lists : catDb.values()){
for(Cat cat : lists){
i++;
maps.put("第"+i+"个", cat);
}
}
return maps;
}

}
