錯誤：如標題

問題描述：

<div class="control-group">
				<label for="resOpsList" class="control-label">對資源的操作：</label>
				<div class="controls">
					<c:forEach items="${resOpMap}" var="map">
						<c:out value="${map.key}" />
						<br>
						<c:forEach items="${map.value}" var="resOp">

		return "redirect:/admin/role";
	}
 

原因：jsp中checkBox屬性name的值原本為resOPList,下面方法的

@RequestParam(value = "resOps")的resOp原本為resOpList，

錯誤資訊是：Field error in object 'role' on field 'resOpList': rejected value [8,9,10]; codes [typeMismatch.role.resOpList,typeMismatch.resOpList,typeMismatch.java.util.List,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [role.resOpList,resOpList]; arguments []; default message [resOpList]]; defaul........
 

解決方法是把resOpList改為一個另外的名稱。
