CFX系列（二）：CXF处理复杂的对象

CXF支持所有的自定义的对象以及常见的诸如List对象，可是对于Map CXF不支持，比如现在服务端根据客户端传递过来一个用户名返回一个MAP形式的权限集合，一发布就会报错，这是需要将map用适配器转换才能发布，本文将做介绍，项目框架沿用第一篇的。

服务端代码：

1：自定义一个MyRole对象

package com.qqw.entity;import java.util.List;public class MyRole {private String key;private List<Role> value;public MyRole() {super();// TODO Auto-generated constructor stub}public MyRole(String key, List<Role> value) {super();this.key = key;this.value = 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;}}

2：在接口HelloWorld返回map的方法里：

package com.qqw.webservice;import java.util.List;import java.util.Map;import javax.jws.WebService;import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;import com.qqw.entity.MapAdapter;import com.qqw.entity.Role;import com.qqw.entity.User;@WebServicepublic interface HelloWorld {public String say(String str);public List<Role> getUserRole(User user);@XmlJavaTypeAdapter(MapAdapter.class)   //采用适配器转换public Map<String, List<Role>> getMap();}

3：用户user

package com.qqw.entity;public class User {private String name;private Integer id;public User() {super();// TODO Auto-generated constructor stub}public User(String name, Integer id) {super();this.name = name;this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}}

4:角色role

package com.qqw.entity;public class Role {private Integer id;private String name;public Role() {super();// TODO Auto-generated constructor stub}public Role(Integer id, String name) {super();this.id = id;this.name = name;}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}

5：定义适配器

package com.qqw.entity;import java.util.HashMap;import java.util.List;import java.util.Map;import javax.xml.bind.annotation.adapters.XmlAdapter;public class MapAdapter extends XmlAdapter<MyRole[], Map<String, List<Role>>>{@Overridepublic 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 myRole = v[i];map.put(myRole.getKey(), myRole.getValue());}return map;}@Overridepublic MyRole[] marshal(Map<String, List<Role>> v) throws Exception {MyRole[] myroles=new MyRole[v.size()];//定义一个实体类数组int i=0;for(String key:v.keySet()){myroles[i]=new MyRole();myroles[i].setKey(key);myroles[i].setValue(v.get(key));i++;}return myroles;}}

6：HelloWorld实现类

@Overridepublic Map<String, List<Role>> getMap() {Map<String, List<Role>> map=new HashMap<String, List<Role>>();List<Role> list=new ArrayList<Role>();list.add(new Role(1, "总经理"));list.add(new Role(2, "技术总监"));List<Role> list1=new ArrayList<Role>();list1.add(new Role(3, "程序呀U呢"));map.put("qqw", list);map.put("qqw1", list1);return map;}

7：接口的东西改了，需要重新在客户端自动生成一边代码,具体怎样自动参考上一篇文章，写一个main方法调用

HelloWorldService hService=new HelloWorldService();HelloWorld helloWorld = hService.getHelloWorldPort();User user=new User();user.setName("qqw1");List<Role> roleList = helloWorld.getUserRole(user);for(int i=0;i<roleList.size();i++){System.out.println("编号："+roleList.get(i).getId()+"/角色名称："+roleList.get(i).getName());}MyRoleArray map = helloWorld.getMap();List<MyRole> list = map.item;for(int i=0;i<list.size();i++){System.out.print(list.get(i).getKey()+":");for(Role r:list.get(i).getValue()){System.out.print(r.getId()+","+r.getName());}System.out.println("================");}

8：后台打印的东西

至此，CXF处理Map类型讲解完毕
