Spring MVC集成Struts Tiles使用方法

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

<% ... @ 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 >
< 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：

 

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
       "-//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

<% ... @ 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 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，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

<! 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

<% ... @ taglib uri="http://jakarta.apache.org/struts/tags-tiles" prefix="tiles"  %>
<% ... @page import="model.Student"  %>
< html >
< head >

</ head >
< body >
< tiles:importAttribute   name ="student"   />
< tiles:useAttribute  id ="student"  name ="student"  scope ="request" />< br >< br >
this is header class from TileContext:${requestScope.student.name }+${requestScope.student.sex } < br >< br >
this is header date from TileContext:  < tiles:getAsString  name ="name" /> + < tiles:getAsString  name ="sex" />< br >< br >
this is header date from request:${requestname }+${requestsex } < br >< br >

</ body >
</ html >

 

运行结果：

the title is:courseDetail title


this is header class from TileContext:gaoxiang+male

this is header date from TileContext: gaoxiang+male

this is header date from request:gaoxiang-request+male-request


this is courseContent
this is footer

 

附：web.xml
