Question

我正在尝试在Spring MVC中运行一个项目。这是代码

的index.jsp

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Welcome to Spring Web MVC project</title>
    </head>

    <body>
        <h1>Spring 3 Register!</h1>
        <a href="register.htm">click</a>
        <form:form action="${pageContext.request.contextPath}/register" method="POST" modelAttribute="userForm">

                    <td><form:input path="username" /></td>
                </tr>
                <tr>

                    <td>Email</td>
                    <td><form:input path="email" /></td>
                </tr>

                </tr>

            </table>
        </form:form>

调度-servlet.xml中

    <context:component-scan base-package="RegisterInfo" />
    <mvc:annotation-driven />
    <!--
    Most controllers will use the ControllerClassNameHandlerMapping above, but
    for the index controller we are using ParameterizableViewController, so we must
    define an explicit mapping for it.
    -->
    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="index.htm">indexController</prop>
            </props>
        </property>
    </bean>

    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix="/WEB-INF/jsp/"
          p:suffix=".jsp" />

    <!--
    The index controller.
    -->
    <bean name="indexController"
          class="org.springframework.web.servlet.mvc.ParameterizableViewController"
          p:viewName="index" />

</beans>

在上面的程序中，每当我提交表单时，我总是会收到此错误

错误：

HTTP Status 400 - Bad Request
The request sent by the client was syntactically incorrect

代码有什么问题？

Answer 1

提交HTTP POST时必须绑定Date。 Spring不知道这是Date，它将其视为String。

添加：

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

给你的控制器。

Answer 2

根据您使用的代码

WITH MEMBER [LastDate] AS 
  tail (
     NonEmpty(
        [BI Dim Date].[Date Key].[Date Key].Members
       ,[Measures].[PRICE]
     )
   ).Item(0).Item(0).name
MEMBER [LastDateWithSales] AS 
  tail (
     NonEmpty(
       [BI Dim Date].[Date Key].[Date Key].Members 
     * [Measures].[PRICE]
     )
   ).Item(0)

SELECT 
{ [Measures].[LastDate], [Measures].[LastDateWithSales]} ON columns,
[MyTest].[ITEMID].[ITEMID] on rows
FROM [MyCube]

上面的代码拼写不正确（htm而不是HTML）。

<prop key="index.htm">indexController</prop>
<a href="register.htm">click</a>

Spring MVC HTTP状态400 - 错误请求
