JasperException: is quoted with " which must be escaped when used within

异常信息：

错误原因：

org.apache.jasper.JasperException: /WEB-INF/view/jsp/default/ui/casLoginView.jsp(48,35) Attribute value request.getQueryString() == null ? "" : request.getQueryString().replaceAll("&locale=([A-Za-z][A-Za-z]_)?[A-Za-z][A-Za-z]|^locale=([A-Za-z][A-Za-z]_)?[A-Za-z][A-Za-z]", "") is quoted with " which must be escaped when used within the value

这句话的意思是说,在value属性中引用"时应该转义,escaped是逃脱逃逸的意思,我们国内的书籍都把这个翻译成了转义。

解决办法：

value="<%=request.getQueryString() == null ? \"\" : request.getQueryString().replaceAll(\"&locale=([A-Za-z][A-Za-z]_)?[A-Za-z][A-Za-z]|^locale=([A-Za-z][A-Za-z]_)?[A-Za-z][A-Za-z]\", \"\")%>"
