收集数组参数

EmpAction.java中

@Controller@RequestMapping(value="/emp")public class EmpAction {@RequestMapping(value="/deleteAll",method=RequestMethod.POST)public String deleteAll(Model model,int[] ids) throws Exception{System.out.println("需要删除的员工编号分别是：");for(int id : ids){System.out.print(id+" ");}model.addAttribute("message","批量删除员工成功");return "/jsp/ok.jsp";}}

jsp中

<%@ page language="java" pageEncoding="UTF-8"%><%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <body>     <form action="${pageContext.request.contextPath}/emp/deleteAll.action" method="POST">    <table border="2" align="center">    <tr>    <th>编号</th>    <th>姓名</th>    </tr>    <tr>    <td><input type="checkbox" name="ids" value="1"/></td>    <td>哈哈</td>    </tr>    <tr>    <td><input type="checkbox" name="ids" value="2"/></td>    <td>呵呵</td>    </tr>    <tr>    <td><input type="checkbox" name="ids" value="3"/></td>    <td>嘻嘻</td>    </tr>    <tr>    <td><input type="checkbox" name="ids" value="4"/></td>    <td>笨笨</td>    </tr>    <tr>    <td><input type="checkbox" name="ids" value="5"/></td>    <td>聪聪</td>    </tr>    <tr>    <td>    <input type="submit" value="删除"/>    </td>    </tr>    </table>    </form>  </body></html>
