Question

我在我的网络应用程序的JSP文件中有以下代码行

<% if (!maintenance) { %>
<customTag:DialogEntry entry="<%=new com.presentation.generic.session.DialogEntry("dialog1","225px","true","true",new String[]{"authentification.Login.action.logInApplicationLabel"},new String[]{"logInApplication()"}) %>"/>
<% } else { %>
<customTag:DialogEntry entry="<%=new com.presentation.generic.session.DialogEntry("dialog1","225px","true","true",new String[]{},new String[]{}) %>"/>
<% } %>

我得到的错误信息是：

/WEB-INF/tags/DialogEntry.tag根据TLD，值属性不接受表达式

如何解决此问题？

DialogEntry.tag：

<%@ attribute name="entry" rtexprvalue="true" type="com.presentation.generic.session.DialogEntry" %>

<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>
<%@ taglib uri="http://struts.apache.org/tags-html-el" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-bean-el" prefix="bean" %>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@ taglib uri="http://struts.apache.org/tags-logic-el" prefix="logic" %>

要么逃避你的内心引号：

<% if (!maintenance) { %>
    <customTag:DialogEntry entry="<%=new com.presentation.generic.session.DialogEntry(\"dialog1\",\"225px\",\"true\",\"true\",new String[]{\"authentification.Login.action.logInApplicationLabel\"},new String[]{\"logInApplication()\"}) %>"/>
<% } else { %>
    <customTag:DialogEntry entry="<%=new com.presentation.generic.session.DialogEntry(\"dialog1\",\"225px\",\"true\",\"true\",new String[]{},new String[]{}) %>"/>
<% } %>

或使用单引号：

<% if (!maintenance) { %>
    <customTag:DialogEntry entry='<%=new com.presentation.generic.session.DialogEntry("dialog1","225px","true","true",new String[]{"authentification.Login.action.logInApplicationLabel"},new String[]{"logInApplication()"}) %>'/>
<% } else { %>
    <customTag:DialogEntry entry='<%=new com.presentation.generic.session.DialogEntry("dialog1","225px","true","true",new String[]{},new String[]{}) %>'/>
<% } %>

阅读错误消息is quoted with " which must be escaped when used within the value您发现文本中包含"是原因。因此，您的文字未定义为"（第二个解决方案，您使用'）或文本中的"有一个\来逃避它们并制作它们是文本中的实际字符。

entry=""

错误TLD在jsp文件中使用
