项目里面HttpSecurity需要配置antMatchers的路径匹配规则,看内部使用的是AntPathMatcher,做了简单的测试比对, 对比了1,2,3级路径,单与双.

• 测试代码:

    public static void main(String[] args) {
        AntPathMatcher pathMatcher = new AntPathMatcher();
        boolean match01 = pathMatcher.match("/monitor/*",    "/monitor");
        boolean match02 = pathMatcher.match("/monitor/**",   "/monitor");
        boolean match03 = pathMatcher.match("/monitor/*/**", "/monitor");
        boolean match04 = pathMatcher.match("/mon*",         "/monitor");
        boolean match05 = pathMatcher.match("/mon*or",       "/monitor");
        boolean match06 = pathMatcher.match("/mon**",        "/monitor");
        boolean match07 = pathMatcher.match("/mon*/*",       "/monitor");
        boolean match08 = pathMatcher.match("/mon*/**",      "/monitor");

        System.out.println("------------------------------------------------------------------------------------------------------------");

        System.out.println("match01:"+ match01);
        System.out.println("match02:"+ match02);
        System.out.println("match03:"+ match03);
        System.out.println("match04:"+ match04);
        System.out.println("match05:"+ match05);
        System.out.println("match06:"+ match06);
        System.out.println("match07:"+ match07);
        System.out.println("match08:"+ match08);

        boolean match11 = pathMatcher.match("/monitor/*",    "/monitor/server");
        boolean match12 = pathMatcher.match("/monitor/**",   "/monitor/server");
        boolean match13 = pathMatcher.match("/monitor/*/**", "/monitor/server");
        boolean match14 = pathMatcher.match("/mon*",         "/monitor/server");
        boolean match15 = pathMatcher.match("/mon*or",       "/monitor/server");
        boolean match16 = pathMatcher.match("/mon**",        "/monitor/server");
        boolean match17 = pathMatcher.match("/mon*/*",       "/monitor/server");
        boolean match18 = pathMatcher.match("/mon*/**",      "/monitor/server");

        System.out.println("------------------------------------------------------------------------------------------------------------");

        System.out.println("match11:"+ match11);
        System.out.println("match12:"+ match12);
        System.out.println("match13:"+ match13);
        System.out.println("match14:"+ match14);
        System.out.println("match15:"+ match15);
        System.out.println("match16:"+ match16);
        System.out.println("match17:"+ match17);
        System.out.println("match18:"+ match18);

        boolean match21 = pathMatcher.match("/monitor/*",    "/monitor/server/detail");
        boolean match22 = pathMatcher.match("/monitor/**",   "/monitor/server/detail");
        boolean match23 = pathMatcher.match("/monitor/*/**", "/monitor/server/detail");
        boolean match24 = pathMatcher.match("/mon*",         "/monitor/server/detail");
        boolean match25 = pathMatcher.match("/mon*or",       "/monitor/server/detail");
        boolean match26 = pathMatcher.match("/mon**",        "/monitor/server/detail");
        boolean match27 = pathMatcher.match("/mon*/*",       "/monitor/server/detail");
        boolean match28 = pathMatcher.match("/mon*/**",      "/monitor/server/detail");

        System.out.println("------------------------------------------------------------------------------------------------------------");

        System.out.println("match21:"+ match21);
        System.out.println("match22:"+ match22);
        System.out.println("match23:"+ match23);
        System.out.println("match24:"+ match24);
        System.out.println("match25:"+ match25);
        System.out.println("match26:"+ match26);
        System.out.println("match27:"+ match27);
        System.out.println("match28:"+ match28);

        System.out.println("------------------------------------------------------------------------------------------------------------");
    }

}

• 输出结果:

------------------------------------------------------------------------------------------------------------
match01:false
match02:true
match03:false
match04:true
match05:true
match06:true
match07:false
match08:true
------------------------------------------------------------------------------------------------------------
match11:true
match12:true
match13:true
match14:false
match15:false
match16:false
match17:true
match18:true
------------------------------------------------------------------------------------------------------------
match21:false
match22:true
match23:true
match24:false
match25:false
match26:false
match27:false
match28:true
------------------------------------------------------------------------------------------------------------

简单总结: *是通配符,匹配一级路径中的任意字符; **单独使用和* 一样,配合/即/**则是多级任意路径(可以没有该级)
