Java6 WebService 施用复杂对象

Java6 WebService 使用复杂对象
Java6 WebService 使用复杂对象?复杂对象可表示的语义比简单对象强大很多，这里看看在Java6的WebService中如何使用复杂对象参数。这里的参数分两类，一类是入参，一类是返回值。?复杂对象在并不像想象中那么简单，其中还有一些玄机。请看实例：?1、开发服务，统统在服务端?package lavasoft.server;

import javax.jws.WebService;
import javax.xml.ws.Endpoint;

/**
* Java6开发的WebService服务端
*
* @author leizhimin 2009-11-16 10:24:13
*/
@WebService
public class Java6WS {

????????//返回一个复杂对象
????????public UserBean doSomething1(String username, String address, boolean flag) {
????????????????return new UserBean(username, address, flag);
????????}

????????//接收一个复杂对象
????????public String doSomething2(Foo foo) {
????????????????return foo.toString();
????????}

????????public static void main(String[] args) {
????????????????//发布一个WebService
????????????????Endpoint.publish("http://192.168.14.117:9999/java6ws/Java6WS", new Java6WS());
????????}
}?package lavasoft.server;

/**
* 用户信息
*
* @author leizhimin 2009-11-16 16:43:35
*/
public class UserBean {
????????private String username;
????????private String address;
????????private boolean flag;

????????public UserBean() {
????????}

????????public UserBean(String username, String address, boolean flag) {
????????????????this.username = username;
????????????????this.address = address;
????????????????this.flag = flag;
????????}

????????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;
????????}

????????public boolean isFlag() {
????????????????return flag;
????????}

????????public void setFlag(boolean flag) {
????????????????this.flag = flag;
????????}

????????@Override
????????public String toString() {
????????????????return "UserBean{" +
????????????????????????????????"username='" + username + '\'' +
????????????????????????????????", address='" + address + '\'' +
????????????????????????????????", flag=" + flag +
????????????????????????????????'}';
????????}
}?package lavasoft.server;

/**
* Created by IntelliJ IDEA.
*
* @author leizhimin 2009-11-16 17:09:46
*/
public class Foo {
????????private String name;
????????private String sex;

????????public Foo() {
????????}

????????public Foo(String name, String sex) {
????????????????this.name = name;
????????????????this.sex = sex;
????????}

????????public String getName() {
????????????????return name;
????????}

????????public void setName(String name) {
????????????????this.name = name;
????????}

????????public String getSex() {
????????????????return sex;
????????}

????????public void setSex(String sex) {
????????????????this.sex = sex;
????????}

????????@Override
????????public String toString() {
????????????????return "Foo{" +
????????????????????????????????"sex='" + sex + '\'' +
????????????????????????????????", name='" + name + '\'' +
????????????????????????????????'}';
????????}
}?2、生成客户端代码???可以清楚的看出，在客户端代码中，已经生成了服务接口和服务实现类，还生成了UserBean和Foo两个类，而这两个类和服务端的内容不同。?3、写客户端测试代码?package lavasoft;

import lavasoft.wsclient.Foo;
import lavasoft.wsclient.Java6WS;
import lavasoft.wsclient.Java6WSService;
import lavasoft.wsclient.UserBean;

/**
* 测试Java6 WS生成的客户端代码
*
* @author leizhimin 2009-11-16 17:05:00
*/
public class TestClient {
????????public static void main(String[] args) {
????????????????//创建一个客户端服务对象
????????????????Java6WS java6WS = new Java6WSService().getJava6WSPort();

????????????????System.out.println("----------java6WS.doSomething1-------------");
????????????????//调用服务方法，并得到方法返回值
????????????????UserBean userBean = java6WS.doSomething1("zhangsan", "华中路", true);
????????????????//打印服务的返回值
????????????????System.out.println(userBean.toString());
????????????????System.out.println(userBean.getUsername() + " " + userBean.getAddress() + " " + userBean.isFlag());

????????????????System.out.println("----------java6WS.doSomething2-------------");
????????????????Foo f = new Foo();
????????????????f.setName("李四");
????????????????f.setSex("Man");
????????????????String sf = java6WS.doSomething2(f);
????????????????System.out.println(sf);
????????}
}?4、执行客户端?执行前先启动服务端。执行结果如下：?可以看出，测试很成功。?5、总结?这里面其实有些细节，需要说明白：1）、对于复杂对象，必须有一个不带参数的构造方法。2）、服务端覆盖Object的方法不能在客户端复原，比如toString方法。3）、服务端的带参数构造方法在客户端失效。?以上三点是非常重要的，如果不知道会很郁闷，老出错还找不到原因。
