我正在尝试使用FilterChainProxy将Spring Security配置从HTTP命名空间转换为直接配置.在转换之前,HTTP命名空间的一切都很好.但是在用FilterChainProxy用几个元素替换元素之后,我在登录系统时遇到了"j_spring_security_check not found"错误.我尝试用"/ app/j_spring_security_check"更改全部或部分"/ j_spring_security_check"但仍无法成功登录.

我的环境:AppFuse 2.1包含Spring MVC,iBatis,Spring Security 3.0.7,tuckey urlrewrite 3.2.0,Spring 3.0.6 Windows 7 JDK 1.5.0_17 Maven 2.2.1 apache-tomcat-6.0.32

Security.xml(在转换之前,一切正常.)

我在使用Jeffrey Friedl的着作Mastering Regular Expressions 3rd Ed的"负面外观"代码运行我的perl脚本时遇到以下错误.(第167页).任何人都可以帮我吗？

错误消息:

序列(？在正则表达式中不完整;用< - HERE标记m /((？< - HERE/at /home/wubin28/mastering_regex_cn/p167.pl第13行.

我的perl脚本

#!/usr/bin/perl

use 5.006;
use strict;
use warnings;

my $str = "<B>Billions and <B>Zillions</B> of suns";

if ($str =~ m!
    (
        <B>
        (
            (?!<B>) ## line 13
            .
        )*?
        </B>
    )
    !x
    ) {
    print "\$1: $1\n"; #output: <B>Billions and <B>Zillions</B>
} else {
    print "not matched.\n";
}
