Hibernate Spring zk Bean DAO

在网上找过很多例子，最后发现官网的这个例子不错。但是过程中出了很多问题，所以记录下来，希望对后来人也有所帮助吧。参考网页：http://www.zkoss.org/smalltalks/hibnsprn/hibn_sprn_zk.html

配置环境：zk +spring 3.0.5.RELEASE + hibernate3.2

1.新建zk project，然后在WEB-INF下引入spring 3.0.5的jar包。因为运行的时候报错了，发现需要一个spring-dao.jar，因为spring 3.0.5 release 中没有，所以需要下载。

2.引入hibernate的 jar包，所有。这个就不用说了吧嘻嘻

3.在WEB-INF下，建立applicationContext.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"

        <property name="password">

        </property>
    </bean>
    <bean id="factory"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

    <bean id="personManager" class="org.zk101.service.PersonManagerImpl">
        <property name="dao">

7. PersonManager Interface

import org.zk101.service.PersonManager;

public class ServiceLocator {

    private static ApplicationContext ctx;

    static {

//注意红色部分，此处最容易报错。因为我的这个配置文件是位于web-inf下的，所以相对于classes的位置就是这样。
        ctx = new ClassPathXmlApplicationContext("../applicationContext.xml");
    }

    private ServiceLocator() {
    }

    public static SessionFactory getSessionFactory() {
        return (SessionFactory) ctx.getBean("factory",SessionFactory.class);
