写在前面话
WebService对List本身就提供了支持，但是对Map结构类型的数据不支持，但是我们可通过将其转换List类似的结构完成对Map的间接支持，服务端在WebService-04的基础上增加一个处理Map的方法，客户端不变，
服务端
创建Web工程，工作结构图如下：
web.xml配置

服务接口
package com.wds.ws.server.spring;
import java.util.Map;
import javax.jws.WebService;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;
import com.wds.ws.server.spring.adapter.XmlAdapterForMapStringUser;
import com.wds.ws.server.spring.model.User;
/**
* 服务接口
* @author wds
*
*/
@WebService
public interface HelloService {
public String sayHi(String userName);
/**
* WebService对Map类型数据处理的方式
* @p@R_502_6460@m type
* @return
*/
@XmlJavaTypeAdapter(value=XmlAdapterForMapStringUser.class)
public Map<String,User> getMapData(String type);
}
采用@XmlJavaTypeAdapter注解指定对Map<String,User>类型的转换类，XmlAdapterForMapStringUser这个类负责在WebService执行时的类型转换，代码如下：
转换类
package com.wds.ws.server.spring.adapter; import java.util.HashMap; import java.util.List; import java.util.Map; import javax.xml.bind.annotation.adapters.XmlAdapter; import com.wds.ws.server.spring.adapter.StringAndUser.Entry; import com.wds.ws.server.spring.model.User; /** * 实现从BoundType到ValueType之间的转换 * @author wds * */ public class XmlAdapterForMapStringUser extends XmlAdapter<StringAndUser,Map<String,User>> { @Override public Map<String,User> unmarshal(StringAndUser stringUser) throws Exception { List<Entry> entrties = stringUser.getEntries(); Map<String,User> result = null; if(entrties != null && entrties.size() > 0){ result = new HashMap<String,User>(); for (Entry entry : entrties) { result.put(entry.getKey(),entry.getValue()); } } return null; } @Override public StringAndUser marshal(Map<String,User> stringUserMap) throws Exception { StringAndUser result = new StringAndUser(); if(stringUserMap != null){ for (String key : stringUserMap.keySet()) { result.getEntries().add(new Entry(key,stringUserMap.get(key))); } } return result; } }
这个转换类的作用就是在WebService支持的数据类型与Map之间做一个转换，而StringAndUser就是将Map转换成了WebService支持的类型，接下来我们看StringAndUser类
StringAndUser类，与Map相等同的数据类型
package com.wds.ws.server.spring.adapter; import java.util.ArrayList; import java.util.List; import com.wds.ws.server.spring.model.User; /** * 与Map<String,User>互相转换的类 Map是由Key和Value构成，可以存放多个Key，类似二维结构的List * 基于此，我们可构成一个List<Object>的数据类型，而这个Object是两个属性，一个是Key，一个是Value * * @author wds * */ public class StringAndUser { private List<Entry> entries = new ArrayList<Entry>(); public List<Entry> getEntries() { return entries; } public void setEntries(List<Entry> entries) { this.entries = entries; } /** * 创建一个关于Entry的内部类 由Key和Value组织 注意内部类的访问权限 */ public static class Entry { private String key; private User value; public Entry() { } /** * 带参数的构造方法 * * @p@R_502_6460@m key * @p@R_502_6460@m value */ public Entry(String key,User value) { this.key = key; this.value = value; } public String getKey() { return key; } public void setKey(String key) { this.key = key; } public User getValue() { return value; } public void setValue(User value) { this.value = value; } } }
服务实现
package com.wds.ws.server.spring.impl;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
import javax.jws.WebService;
import com.wds.ws.server.spring.HelloService;
import com.wds.ws.server.spring.model.User;
/**
* 服务实现类
* 关于@WebService在上面有介绍过
* @author wds
*
*/
@WebService(endpointInterface="com.wds.ws.server.spring.HelloService",portName="hwPort",serviceName="hwService")
public class HelloServiceImpl implements HelloService {
@Override
public String sayHi(String userName) {
String result = new Date() + " " + userName;
System.out.println("Server: " + result);
return result;
}
@Override
public Map<String,User> getMapData(String type) {
Map<String,User> result = new HashMap<String,User>();
User user = new User("no.1","address one");
result.put("one1",user);
user = new User("no.2","address two");
result.put("one2",user);
user = new User("no.3","address three");
result.put("one3",user);
return result;
}
}
user类
package com.wds.ws.server.spring.model;
public class User {
private String userName;
private String address;
public User() {
}
public User(String userName,String address) {
this.userName = userName;
this.address = address;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
将服务部署到Tomcat下，启动
客户端
客户端如WebService-04的方式，切换到cxf的bin目录下，执行以下命令：
wsdl2java -p com.wds.ws.client.spring http://localhost:8080/com.wds.ws.server.spring/cxf/helloworld?wsdl
-p是指定包结构
将产生的类复制到工作中去，工作结构如下：
编写Client测试类，代码如下：
package com.wds.ws.client;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.List;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import com.wds.ws.client.spring.Entry;
import com.wds.ws.client.spring.HelloService;
import com.wds.ws.client.spring.StringAndUser;
/**
* 客户端
* @author wds
*
*/
public class Client {
/**
* 命令
* 我的cxf的包放到f:/package，可根据实际目录调整
* F:\Package\apache-cxf-2.7.3\bin>wsdl2java -p com.wds.ws.client.spring http://localhost:8080/com.wds.ws.server.spring/cxf/helloworld?wsdl
*/
/**
* WSDL的地址
*/
private final static String url = "http://localhost:8080/com.wds.ws.server.spring/cxf/helloworld?wsdl";
/**
* 命名空间，在WSDL根节点中的targetNameSpace
*/
private final static String nameSpace = "http://impl.spring.server.ws.wds.com/";
/**
* 服务名称，在WSDL文件中的节点为<wsdl:sevice name="XXX">的name属性值
*/
private final static String sName = "hwService";
/**
* @p@R_502_6460@m args
*/
public static void main(String[] args) {
try {
//生成wsdlUrl对象
URL wsdlUrl = new URL(url);
//ServiceName
QName serviceName = new QName(nameSpace,sName);
//创建Service对象
Service service = Service.create(wsdlUrl,serviceName);
//获取port，HelloService为port的类型
HelloService hwService = service.getPort(HelloService.class);
//执行方法调用
String result = hwService.sayHi("wds");
StringAndUser stringUser = hwService.getMapData("map");
List<Entry> entries = stringUser.getEntries();
//输出getMapData方法的结果
for (Entry entry : entries) {
System.out.println("Key:" + entry.getKey() + " Value:" + entry.getValue());
}
//输出sayHi的结果
System.out.println(result);
} catch (MalformedURLException e) {
e.printstacktrace();
}
}
}
测试即可。
