struts2從action向jsp傳參數:
1.在action類里面的成員變量域那里寫上你要返回給jsp的變量和相應的get set方法(比如list)..
在execute方法里為list填充了數據..
2.直接在jsp調用.
1).加上<%@ taglib uri="/struts-tags" prefix="s" %>標簽
2).<s:iterator value="list">
<s:property/>
</s:iterator>
另外如果list里面放的是一個model,例如User(包含有name和password),
則可以:
<s:iterator value="list">
<s:property value="name"/>
<s:property value="password"/>
</s:iterator>
附上簡單的一個例子:
action:
View Code
1 private List<String> testnames; 2 3 public List<String> getTestnames() { 4 return testnames; 5 } 6 public void setTestnames(List<String> testnames) { 7 this.testnames = testnames; 8 } 9 10 11 public String getUsers(){ 12 testnames = new ArrayList<String>(); 13 testnames.add("kim"); 14 testnames.add("deng"); 15 16 return SUCCESS; 17 }
jsp:
View Code
1 <%@ page language="java" contentType="text/html; charset=GB18030" 2 pageEncoding="GB18030"%> 3 <%@ taglib uri="/struts-tags" prefix="s" %> 4 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 5 <html> 6 <head> 7 <meta http-equiv="Content-Type" content="text/html; charset=GB18030"> 8 <title>Insert title here</title> 9 </head> 10 <body> 11 <s:iterator value="testnames"> 12 <s:property/> 13 </s:iterator> 14 </body> 15 </html>
