本文通过具体示例介绍了如何在Java中正确使用泛型来处理一对多关系的数据模型，并展示了如何将这些模型与Spring框架集成以提供Web服务。

基础类型做 helloWord 网上随便找两篇文章就可以做！但真的有意思吗？

我可以肯定告诉你绝对不行！除非你只传递基础类型，如果只要这样的需求您不必往下看了！

如果有两个model有相互关联关系应该怎么做呢？

其实重点就是定义泛型

举个简单例子

User.java

user有多个book 定义List必须用泛型否则有

ouldn't create type for property books on class com.demo.model.User 异常

它包含了多个book对象

package com.demo.model; import java.util.List; public class User { private Integer id; private String userName; private String password; private List<Book> books; //List books这样是错误的！ public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public List<Book> getBooks() { return books; } public void setBooks(List<Book> books) { this.books = books; } }

Book.java

package com.demo.model; public class Book { private Integer id; private String name; private Double money; private User user; public User getUser() { return user; } public void setUser(User user) { this.user = user; } public Double getMoney() { return money; } public void setMoney(Double money) { this.money = money; } 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; } }

两个对象有1对多关系

建立一个接口和一个实现类

接口:UserAction

package com.demo.action; import java.util.List; import com.demo.model.User; public interface UserAction { public List<User> getUserAll(); public void save(User user); }

实现类UserActionImpl

package com.demo.action; import java.util.ArrayList; import java.util.List; import com.demo.model.Book; import com.demo.model.User; @SuppressWarnings("all") public class UserActionImpl implements UserAction { public List<User> getUserAll() { List list = new ArrayList(); User user = new User(); user.setId(1); user.setUserName("xiaomaha"); user.setPassword("123"); Book book = new Book(); book.setId(1); book.setMoney(12.5); book.setName("j2ee"); List l = new ArrayList<Book>(); l.add(book); user.setBooks(l); list.add(user); return list; } public void save(User user) { // TODO Auto-generated method stub System.out.println(user.getUserName()); System.out.println(user.getPassword()); } }

现在引入spring.

配置文件如下

spring_xfire.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"> <bean name="userXfire" class="org.codehaus.xfire.spring.ServiceBean" >  <property name="serviceBean" ref="userAction" />  <property name="serviceClass" value="com.demo.action.UserAction" /> </bean>  <bean id="userAction" class="com.demo.action.UserActionImpl"> </bean> </beans>

web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">  <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:org/codehaus/xfire/spring/xfire.xml, classpath:spring_xfire.xml </param-value> </context-param>  <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener>  <servlet> <servlet-name>XFireServlet</servlet-name> <servlet-class> org.codehaus.xfire.spring.XFireSpringServlet </servlet-class> <load-on-startup>0</load-on-startup> </servlet>  <servlet-mapping> <servlet-name>XFireServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>

使用myEclipse 的 Web Services Explorer 就可以测试了，当然你也可以写一个
