jakarta-ee - javax.el.E​​LException : The identifier [return] is not a valid Java identifier

Question

我有一个页面 url，它看起来像:

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

安装 tomcat 7 后，尝试访问它时出现此异常:

/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.

任何想法为什么我得到那个？要修复它，我应该只在 tomcat 中更改此属性吗？

Answer 1

return是 Java Programming Language(tm) 中的保留关键字。但幸运的是，还有另一种拼写。试试 param['return']反而。
