Question

我是Spring MVC的新手。我在运行项目时遇到了错误 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。我的控制器是Patient Controller。我想要实现的功能是将值插入数据库。但我无法在控制器中调用我的函数（add-update2）。

Answer 1

我认为问题是Spring在

中提交以下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PropertyEditor。例如，将以下内容添加到@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更改为客户端发送的任何内容。

在相关说明中，您通过发送重定向

发送302响应

return "redirect:/full-reg";

请记住，请求和模型属性仅在一个请求的持续时间内存在。因此，当您的客户端将请求发送到full-reg时，您最初发送的表单输入参数都不再存在。你应该重新思考如何做到这一点。

Answer 2

今天早上我遇到了同样的错误。我的代码的问题是我在表单绑定对象中将变量声明为整数，但在实际表单中我捕获了文本。为我改变变量到正确的类型

Answer 3

当定义的绑定与用户发送的内容不匹配时，会发生这种情况。最常见的问题是：

缺少PathVariable声明
Incomplete PathVariable声明（例如缺少值=“variableName”）
错误的数据类型，例如Sotirios Delimanolis的回答。如果无法序列化输入参数的类，则请求不可处理

所以，一般来说，请确保：

声明每个PathVariable
分配的值对应于路径中匹配的值 - @PathVariable(value="myVariableName", String myVariable)路径定义@RequestMapping(value = "/userInfo/myVariableName", method = RequestMethod.GET)
为PathVariable声明的每个类都必须是可序列化的。

Answer 4

就我而言，我尝试创建一个ID和NAME作为属性的对象。 ID为int，NAME为String。 但是我的js设置了这样的值 ID =＆＃39;＆＃39;，NAME =＆＃39; brabrabra ...＆＃39;

设置ID = 0后，问题得到解决。

Answer 5

我最近有一个类似的问题，并通过用@DateTimeFormat注释我的Date字段来解决。就您而言，您可以将PatientInfo.java文件编辑为：

    import org.spring.framework.annotation.DateTimeFormat;

    @Column(name = "DateOfBirth")
    @Temporal(TemporalType.TIMESTAMP)
    @DateTimeFormat(pattern = ${pattern})
    private Date dateOfBirth;

请确保将${pattern}替换为表示将要接收的格式的字符串（例如“ yyyy-MM-dd”）。

客户端发送的请求在语法上是不正确的。-Spring MVC + JDBC Template
