java - 处理 JSP page/WEB-INF/views/ViewPage.jsp 第 130 行时发生异常

Question

在 Servlet.xml 中

<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="messages"/>
    <property name="defaultEncoding" value="UTF-8" />
</bean>

在 src/resources/messages.properties 文件中的 messages.properties 文件中

label.employeeId=Emp.ID
label.employeeName=Employee Name
label.dateOfBirth=DOB
label.annualIncome=Annual Income
label.bloodGroup=Blood group
label.qualification=Qualification
label.sex=Sex
label.phoneNumber=Phone No.
label.email=Email
label.edit=Edit
label.delete=Delete

jsp 文件代码片段和标签。

    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
    <%@taglib uri="http://www.springframework.org/tags" prefix="spring" %>
    <%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
    <%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
    <%@ page session="false" %>

    <table border="0" cellpadding="0" cellspacing="0">

      <tr>  
        <td width="5%"><label for="Emp.ID"><spring:message code="label.employeeId"/></label></td>
        <td width="22%"><label for="Employee Name"><spring:message code="label.employeeName"/></label></td>
        <td width="6%"><label for="DOB"><spring:message code="label.dateOfBirth"/></label></td>
        <td width="7%"><label for="Annual Income"> <spring:message code="label.annualIncome"/></label> </td>
        <td width="9%"><label for="Blood group"> <spring:message code="label.bloodGroup"/></label> </td>
        <td width="11%"><label for="Qualification"> <spring:message code="label.qualification"/></label></td>
        <td width="7%"><label for="Sex"> <spring:message code="label.sex"/></label></td>
        <td width="10%"><label for="Phone No."> <spring:message code="label.phoneNumber"/></label></td>
        <td width="9%"><label for="Email"> <spring:message code="label.email"/></label></td>
        <td width="7%"><label for="Edit"> <spring:message code="label.edit"/></label></td>
        <td width="7%"><label for="Delete"> <spring:message code="label.delete"/></label></td>

      </tr>

当我运行这个程序时，我收到如下错误

     Exception report
     message An exception occurred processing JSP page /WEB-INF/views/ViewPage.jsp at line 130
      description The server encountered an internal error that prevented it from fulfilling this request.

当运行我的程序时，我遇到了上述错误，我已经发布了我的属性文件、jsp 文件和 servlet.xml 文件，请帮助我修复此错误。我已将 messages.properties 文件放置在 src/resource 文件夹/messages.properties 文件

Answer 1

异常的根本原因很明确:

javax.servlet.jsp.JspTagException: No message found under code 'label.employeeId' for locale 'en_US'.

在您的属性文件中，您缺少属性label.employeeId。请将其添加到您的 messages.properties 属性文件中。

更正:由于您的属性文件中已有 label.employeeId，因此您的文件位置可能位于错误的位置。也许它应该位于 src/main/resources/目录中(如果您的项目是 Maven 化的)。
