struts2.0 el不�v作用

豪情 — Mon, 24 May 2010 07:31:00 GMT

1.讄��整个��目使用el表达式，需要在web.xml中加�?nbsp;�Q�控制一个项目）
< jsp-config >
< jsp-property-group >
< el-ignored >false < / el-ignored >
< /jsp-property-group >
< / jsp-config >

2.讄��某个jsp��面使用el表达式，需要在jsp��面加上�Q�控制单个页面）
<%@ page isELIgnored="false"%>

3.看你的web.xml文�g中头的引用应该是 2.4.xsd

${requestScope.hello}

sdf

��JSP��面中的<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%>改�ؓ<%@ taglib uri=http://java.sun.com/jstl/core_rt prefix="c"%>卛_��?/span>

发现一个el表达式在JSP2.0中不起作用的问题。反复调试多�ơ，发现是web.xml中出了问题。猜��是版本的问题，但只知道了如何修改，不知道�ؓ什么那样修攏V�?br />
web.xml

xml version="1.0" encoding="ISO-8859-1"?>

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
 version="2.4">
2.4版本默认启用el表达式，如果使用2.5版本�Q�默认el表达式是关闭�?br />
xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5"
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
那么对应2.5的web.xml --> jsp��面里应该增�?/span><%@ page isELIgnored="false"%>

发现原因�Q�一句话�Q�凡是部�|�描�q�文仉��循Servlet2.4规范的WEB应用�Q�EL表达式的计算默认是启用的�Q�而未遵��@的，则EL表达式的计算默认是禁用的�?br />
所以解��x��案还可以是：��web.xml中的DTD(文档�c�d��定义)攚w��2.4的版�?

struts2 标签的��用之�?s:iterator(修正)

豪情 — Fri, 21 May 2010 15:49:00 GMT

来自于：http://www.aygfsteel.com/michaellee/archive/2009/07/14/286733.html

struts2的s�Q�iterator 可以遍历数据栈里面的��M��数组�Q�集合等�{?nbsp;以下几个��单的demo�Q?br /> s:iterator 标签�?个属性：
 value�Q�被�q�代的集�?br /> id �Q�指定集合里面的元素的id
 status �q�代元素的烦�?br />
1:jsp��面定义元素写法数组或list

 1. <s:iterator value="{'1','2','3','4','5'}" id='number'>
 2. <s:property value='number'/>A
 3. s:iterator>

打印�l�果�? 1A2A3A4A5A
上面的方法我在jsp文�g里执行没有成�?�q�是另一�U�写法：
<%
 List list = new ArrayList();
 list.add("Max");
 list.add("Michael");
 list.add("Scott");
 list.add("Jeffry");
 list.add("Joe");
 request.setAttribute("names", list);
 %>

<h3>Names:h3>

 <ol>
 <s:iterator value="#request.names" status="stuts">
 <s:if test="#stuts.odd == true">
 <li>White <s:property/>li>
 s:if>
 <s:else>
 <li style="background-color:blue"><s:property/>li>
 s:else>
 s:iterator>
 ol>

2: 索引的用�?br /> 如果指定了status�Q�每�ơ的�q�代数据都有IteratorStatus的实例，它有以下几个�Ҏ��
int getCount()�q�回当前�q�代了几个元�?br /> int getIndex()�q�回当前元素索引
boolean isEven()当然的烦引是否偶�?br /> boolean isFirst()当前是否�W�一个元�?br /> boolean isLast()
boolean isOdd() 当前元素索引是否奇数

 1. <s:iterator value="{'a','b','c'}" id='char' status='st'>
 2. <s:if test="#st.Even">
 3. 现在的烦引是奇数�?<s:property value='#st.index'/>
 4. s:if>
 5. 当前元素��|��<s:property value='char'/>
 6. s:iterator>

3�Q�遍历map
value可以直接定义为：

 1. value="#{"1":"a","2":"b"}"

每个元素以都好隔开。元素之间的key和value 冒号隔开
value 也可以是数据栈里面的java.util.Map对象
遍历写法如下�Q?br />
 1. <s:iterator value="map" id="id" status="st">
 2. key : <s:property value='key'/>
 3. value:<s:property vlaue='value'/>
 4. s:iterator>

当然key 和value 都可以��java �?nbsp;Object

3�Q�遍历数据栈.��单的List�c�，
List<Attr>
class Attr{String attrName;String getAttrName(){return "123";}}

 1. <s:iterator value="label" id="id">
 2. <s:property value="#id.attrName" />
 3. s:iterator>

当然 value �q�可以写�?nbsp;value="%{label}" label 可以�?操作
label的属性List 可以写成value="%{label.list}" 相当于：getLabel().getList();

4�Q�遍�?个list�Q?br /> List<AttrName> attrN {color,size,style}
List<AttrValue> attrV {red,20,gay}
�q?�?nbsp;list的元素是一一对应的，一个attrN对应一个attrV

 1. <s:iterator value="%{attrN }" id="id" status="status">
 2. index is : <s:property value='status.index'/>
 3. attrName is : <s:property value='id'/> or <s:property value='%{id}'/>
 4. attrName is : <s:property value='%{attrV[#status.index]}'/>
 5. s:iterator>
