T5+spring2.0+hibernate3.2使用OpenSessionInViewFilter

按照网上讲的方法，在web.xml文件中加入filter，在页面访问延时加载的数据时，报session关闭的错误，仔细检查代码未发现问题
后又仔细检查了web.xml文件，尝试调整了filter的顺序，居然成功了
现将各部分代码贴出来

例子有三个类，分别是：Man,Address,Phone

分别存放人的信息，人的地址，人的电话号码

详细请看代码
web.xml文件内容：

service部分代码就不贴了，下面贴下TestMan1.tml代码：

	private Man man;

	private Phone phone;

	public Collection<Man> getMans() {

	}

	public Collection<Phone> getPhones() {

發一個demo 上來。。比較直觀點啦
