首先，我们定义一个总体的tiles视图 /tiles/mainTemplate.jsp
首先使用:<tiles:getAsString name="title"/>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
Html代码
<%@taglib uri="http://jakarta.apache.org/struts/tags-tiles" prefix="tiles"%>
<html>
<head>
<title><tiles:getAsString name="title"/></title>
</head>
<body>
the title is:<tiles:getAsString name="title"/><br>
<tiles:insert name="header"/><br>
<tiles:insert name="content"/><br>
<tiles:insert name="footer"/><br>
</body>
</html>
header.content.footer页面如下：
Html代码
<html>
<head>
</head>
<body>
this is from header
</body>
</html>
<html>
<head>
</head>
<body>
this is from content
</body>
</html>
<html>
<head>
</head>
<body>
this is from footer</body>
</html>
Spring MVC 控制类：
Java代码
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
Xml代码
<!DOCTYPE tiles-definitions PUBLIC
"-//Apache Software Foundation//DTD Tiles Configuration//EN"
"http://jakarta.apache.org/struts/dtds/tiles-config_1_1.dtd">
<tiles-definitions>
<definition name="template" page="/tiles/mainTemplate.jsp">
<put name="title" value="default title"/>
<put name="header" value="="/tiles/header.jsp"/>
<put name="content" value="/tiles/content.jsp"/>
<put name="footer" value="/tiles/footer.jsp"/>
</definition>
<!--以courseDetail命名的配置，覆盖了模板中的title和content对应的页面-->
<definition name="courseDetail" extends="template">
<put name="title" value="courseDetail title"/>
<put name="content" value="/tiles/courseContent.jsp"/>
</definition>
</tiles-definitions>
/title/courseContent.jsp
Html代码
<%@taglib uri="http://jakarta.apache.org/struts/tags-tiles" prefix="tiles" %>
<html>
<head></head>
<body>
this is courseContent
</body>
</html>
spring配置文件：
Xml代码
<?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="simpleUrlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/tiles.mvc">TilesController</prop>
</props>
</property>
</bean>
<bean id="TilesController" class="Action.TilesHomeController">
</bean>
<!-- tiles页面解析器-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass">
<value>org.springframework.web.servlet.view.tiles.TilesView</value>
</property>
</bean>
<!-- tiles配置器-->
<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles.TilesConfigurer">
<property name="definitions">
<list>
<value>/WEB-INF/train-def.xml</value>
</list>
</property>
</bean>
</beans>
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，为了解决这个问题，我们可以使用spring为我们提供的ComponentControllerSupport
Java代码
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
Xml代码
<!DOCTYPE tiles-definitions PUBLIC
"-//Apache Software Foundation//DTD Tiles Configuration//EN"
"http://jakarta.apache.org/struts/dtds/tiles-config_1_1.dtd">
<tiles-definitions>
<definition name="template" page="/tiles/mainTemplate.jsp">
<put name="title" value="default title"/>
<put name="header" value=".header"/>
<put name="content" value="/tiles/content.jsp"/>
<put name="footer" value="/tiles/footer.jsp"/>
</definition>
<definition name="courseDetail" extends="template">
<put name="title" value="courseDetail title"/>
<put name="content" value="/tiles/courseContent.jsp"/>
</definition>
<definition name=".header" page="/tiles/header.jsp" controllerClass="Action.HeaderTilesController">
</definition>
</tiles-definitions>
改header.jsp
Html代码
<%@ taglib uri="http://jakarta.apache.org/struts/tags-tiles" prefix="tiles" %>
