name:指的是从上一个页面或者action里面传过来的变量Q可以是Mcd?例如再上一|页定义request.setAttribute("requestName", requestName);)
例如Q?
我有一个Bean对象User对象Q这个里面保存了admin理员的个h信息Q姓?name)Q性别(sex)、年?age)那么怎么用呢?
在action里面你可以把User对象传过?
request.setAttribute("user",User);
在页?
<bean:define id="admin" name="user"./>
然后可以和bean:write搭配使用
<bean:write name="admin" property="name"/>
<bean:write name="admin" property="sex"/>
<bean:write name="admin" property="age"/>

在具体的目应用?我们很少会用C对一的联操?且很多时候一对一的操作可以通过多对一实现,但是一对一有自q好处,是在Q何时候都能保证主外键数据的一致?但是多对一的情况下未必能做?
我在目中具体用C一对一的联操?从网上拿?一个例子来?但是没有成功,于是只好自己研究,现在把修改后的代码帖出来.

2.声明一个接?/span>

3.实现接口的类

public class ExcelManagerImpl implements ExcelManagerIf
{
public boolean export1(HttpServletResponse response, List list,LinkedHashMap hashMap)

4.调用

List list = Object.getList();
ExcelManagerIf eem = ExcelManagerFactory.getInstance();
