首先，我们定义一个总体的tiles视图 /tiles/mainTemplate.jsp 首先使用:打印tiles配置文件中定义的字符串属性title

然后是分别加载header,content,footer三个jsp页面，共同组成mainTemplate.jsp

Spring MVC 控制类：
package
Action;
import
java.util.ArrayList;
import
java.util.List;
import
javax.servlet.http.HttpServletRequest;
import
javax.servlet.http.HttpServletResponse;
import
model.Student;
import
org.springframework.validation.BindException;
import
org.springframework.web.servlet.ModelAndView;
import
org.springframework.web.servlet.mvc.AbstractCommandController;
public
class
TilesHomeController
extends
AbstractCommandController
...
{
protected
ModelAndView handle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, BindException arg3)
throws
Exception
...
{
return
null
;
}
protected
ModelAndView handleRequestInternal(HttpServletRequest arg0, HttpServletResponse arg1)
throws
Exception
...
{
return
new
ModelAndView(
"
courseDetail
"
,
""
,
""
);
}
}
当我们运行上面这个控制器时候，系统会自动去寻找courseDetail.jsp这个文件，但我们还没有定义这个文件，所以，我们要这样写tiles-def.xml
DOCTYPE tiles-definitions PUBLIC

运行/title.mvc （mvc是我自定义的扩展名）我们可以看到如下结果：
courseDetail title
this is from header
this is courseDetail
this is from footer
如果我们需要在每一个页面的header部分显示一些我们从数据库里读取的数值，我们可以在不同的控制器中加入访问数据库的代码，但这样显得很啰唆，因为header部门在每个页面都是公用的，也就是说不同的页面只有content部分不同，这样，我们就会有很多冗余代码，未解决这个问题，我们可以使用spring为我们提供的ComponentControllerSupport
package
Action;
import
javax.servlet.http.HttpServletRequest;
import
javax.servlet.http.HttpServletResponse;
import
model.Student;
import
org.apache.struts.tiles.ComponentContext;
import
org.springframework.web.servlet.view.tiles.ComponentControllerSupport;
public
class
HeaderTilesController
extends
ComponentControllerSupport
...
{
protected
void
doPerform(ComponentContext context, HttpServletRequest request,
HttpServletResponse response)
throws
Exception
...
{
Student stu
=
new
Student();
stu.setName(
"
gaoxiang
"
);
stu.setSex(
"
male
"
);
//
tiles context中存放简单数据
context.putAttribute(
"
name
"
, stu.getName());
context.putAttribute(
"
sex
"
, stu.getSex());
//
tiles context中存放对象
context.putAttribute(
"
student
"
, stu);
//
request中存放数据
request.setAttribute(
"
requestname
"
, stu.getName()
+
"
-request
"
);
request.setAttribute(
"
requestsex
"
, stu.getSex()
+
"
-request
"
);
}
}
改写train-def.xml
