我是Spring MVC的新手.

執行我的專案時,我遇到錯誤

錯誤 – 客戶端傳送的請求在語法上不正確.

我有一個實體類PatientInfo.

我的jsp頁面是demo1.

我的控制器是病人控制器.

我想要實現的功能是將值插入資料庫.

但是我無法在控制器中呼叫我的函式(add-update2).

demo1.jsp

我認為問題是,Spring不知道如何反序列化您的瀏覽器客戶端在提交以下輸入欄位時傳送的日期

<tr name="tstest">
<td>Date Of Birth</td>
<td><form:input path="dateOfBirth" name="timestamp" value=""/>
<a href="javascript:show_calendar('document.tstest.timestamp', document.tstest.timestamp.value);"><img src="../images/cal.gif" width="16" height="16" border="0" alt="Click Here to Pick up the timestamp"></a>
</td>
</tr>

Spring不知道如何獲取您輸入該欄位的值並將其轉換為Date物件.您需要註冊一個PropertyEditor.例如,將以下內容新增到您的@Controller類中

@InitBinder
public void initBinder(WebDataBinder binder) {
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
sdf.setLenient(true);
binder.registerCustomEditor(Date.class, new CustomDateEditor(sdf, true));
}

顯然,將SimpleDateFormat更改為客戶端傳送的任何內容.

在相關的說明中,您將通過傳送重定向傳送302響應

return "redirect:/full-reg";

請記住,請求和模型屬性僅在一個請求的持續時間內生效.因此,當您的客戶端將請求傳送到full-reg時,您傳送的表單輸入引數最初都不存在.你應該重新考慮你如何做到這一點.
