javax.el.E​​LException：标识符[return]不是有效的Java标识符 [英] javax.el.ELException: The identifier [return] is not a valid Java identifier

问题描述

我有一个页面网址，看起来像：

I have a page url, which looks like:

http://mydomain.com/nodes/32/article/new?return=view

安装tomcat后7，当试图访问它时我得到了这个例外：

After installing tomcat 7, when trying to access it I got this exception:

/nodes/${param.id}/article/new?return=${param.return}
contains invalid expression(s): javax.el.ELException: The identifier [return] is not a valid Java identifier as required by section 1.19 of the EL specification (Identifier ::= Java language identifier). This check can be disabled by setting the system property org.apache.el.parser.SKIP_IDENTIFIER_CHECK to true.

任何想法我为什么会这样做？要修复它，我应该只在tomcat中更改此属性吗？

Any ideas why I get that? To fix it should I change this property in tomcat only?

推荐答案

return 是Java编程语言（tm）中的保留关键字。但幸运的是，有一种替代拼写。请尝试 param ['return'] 。

return is a reserved keyword in the Java Programming Language(tm). But luckily there is an alternative spelling. Try param['return'] instead.
