springmvc参数绑定-复杂绑定

<form action="${pageContext.request.contextPath }/user/queryUsers.action" method="post">		<table>			<tr>				<td>名称：<input name="userCustom.name" />					<input type="submit" value="提交" />				</td>			</tr>	</form>Controller：
@RequestMapping("/queryUsers")	public String queryUsers(Model model, UsersQueryVo usersQueryVo) throws Exception {		List<UserCustom> usersList = usersservice.findUsersList(usersQueryVo);		model.addAttribute("userList", usersList);		return "user/user";	}注意：一定要考虑程序的可扩展性，多用包装类，应对多个pojo数组类型绑定需求：批量删除用户实现方式：jsp多选框名称和形参名称保持一致jsp页面:
<c:forEach items="${userList}" var="item">		<tr>			<td><input type="checkbox" name="user_id" value="${item.id }" /></td>			<td>${item.name}</td>		</tr></c:forEach>Controller：
@RequestMapping("/deleteUsers")	public String deleteUsers(Integer[] user_id) throws Exception {		return "success";	}List集合类型绑定需求：批量修改用户信息实现方式：1.查询包装类里添加集合属性，用于修改的信息传递到Controller2.前端页面注意是按照集合索引的形式赋值jsp页面:
<form name="form1"		action="${pageContext.request.contextPath }/user/editAllUsersSubmit.action"		method="post">		<table>			<tr>				<td colspan="4"><input type="submit" value="批量修改" /></td>			</tr>			<tr>				<td>name</td>				<td>age</td>				<td>address</td>				<td>modifytime</td>			</tr>			<c:forEach items="${userList}" var="item" varStatus="status">				<tr>					<td><input name="userCustoms[${status.index}].name"						value="${item.name}" /></td>					<td><input name="userCustoms[${status.index}].age"						value="${item.age}" /></td>					<td><input name="userCustoms[${status.index}.address"						value="${item.address}" /></td>					<td><input name="userCustoms[${status.index}].modifytime"						value='<fmt:formatDate value="${item.modifytime }"							pattern="yyyy-MM-dd HH:mm:ss" />' /></td>				</tr>			</c:forEach>		</table>	</form>Controller：
@RequestMapping("/editAllUsers")	public String editAllUsers(Model model) throws Exception {		List<UserCustom> usersList = usersService.findUsersList(null);		model.addAttribute("userList", usersList);		return "user/editAllUsers";	}	@RequestMapping("/editAllUsersSubmit")	public String editAllUsersSubmit(UsersQueryVo usersQueryVo) throws Exception {		return "success";	}pojo包装对象：
public class UsersQueryVo {	PRivate List<UserCustom> userCustoms;	public List<UserCustom> getUserCustoms() {		return userCustoms;	}	public void setUserCustoms(List<UserCustom> userCustoms) {		this.userCustoms = userCustoms;	}}Map类型绑定在包装类中定义Map对象，并添加get/set方法，action使用包装对象接收。jsp页面：
<tr><td>信息：</td><td>姓名：<inputtype="text"name="itemInfo['name']"/>年龄：<inputtype="text"name="itemInfo['age']"/>.. .. ..</td></tr>Contrller：
public String useraddsubmit(Model model,QueryVo queryVo)throws Exception{System.out.println(queryVo.getStudentinfo());}包装类中定义Map对象如下：
Public class QueryVo {private Map<String, Object> itemInfo = new HashMap<String, Object>();  //get/set方法..}
