我正在创建一个简单的注册应用程序，但我陷入了困境。
以下是我的index.jsp文件
index.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<html:html>
<head>
<title><bean:message key="registration.jsp.title"/></title>
<style type="text/css">
.error { color: red; font-weight:bold }
</style>
</head>
<body>
<h1><bean:message key="registration.jsp.heading"/></h1>
<logic:present name="registration-successful" scope="request">
<h2>
<bean:message key="registration.jsp.registration-successful"/>
<bean:write name="registration-successful" property="userid" />
</h2>
</logic:present>
<logic:notPresent name="registration-successful" scope="request">
<html:form action="Registration.do" focus="userid">
<dl>
<dt><bean:message key="registration.jsp.prompt.userid"/></dt>
<dd>
<html:text property="userid" size="20" />
<span class="error"><html:errors property="userid" /></span>
</dd>
<dt><bean:message key="registration.jsp.prompt.password"/></dt>
<dd>
<html:text property="password" size="20" />
<span class="error"><html:errors property="password" /></span>
</dd>
<dt><bean:message key="registration.jsp.prompt.password2"/></dt>
<dd><html:text property="password2" size="20" /></dd>
<dt><html:submit property="submit" value="Submit"/>
<html:reset/>
</dt>
</dl>
</html:form>
</logic:notPresent>
</body>
</html:html>
我的 Application.properties 文件包含在 /WEB-INF/resources 文件夹中
以下是 struts-config.xml:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>
<form-beans>
<form-bean name="RegistrationForm"
type="net.thinksquared.registration.RegistrationForm"/>
</form-beans>
<action-mappings>
<action path="/Registration"
type="net.thinksquared.registration.RegistrationAction"
name="RegistrationForm"
scope="request"
validate="true"
input="/index.jsp">
<forward name="success" path="/index.jsp"/>
</action>
</action-mappings>
<message-resources parameter="Application"/>
</struts-config>
最佳答案
你应该有Application.properties文件在src文件夹中。该属性文件应包含您通过 <bean:message> 在 JSP 中获取的消息的键值对。标签。例如
registration.jsp.title = My registration title
并且您可以使用key通过文件中应该唯一的键检索此消息标签的属性。
关于java - 缺少 key "registration.jsp.title"的消息，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17318577/
