我是 Spring MVC 的新手。我在运行项目时遇到错误错误 - 客户端发送的请求在语法上不正确。我有一个实体类 PatientInfo。我的jsp页面是demo1。我的 Controller 是患者 Controller 。我要实现的功能是将值插入数据库。但我无法在 Controller 中调用我的函数(add-update2)。

demo1.jsp

最佳答案

我认为问题在于 Spring 在提交以下 input 字段时不知道如何反序列化浏览器客户端发送的日期

<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 不知道如何获取您在该字段中输入的值并将其转换为 Date 对象。您需要为此注册一个 PropertyEditor。例如，将以下内容添加到您的 @Controller 类

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

显然，将 SimpleDateFormat 更改为您的客户端发送的任何内容。

在相关说明中，您通过发送重定向来发送 302 响应
