Spring PathPatternParser 和AntPathMatcher 的使用以及性能

//上代码
public static void main(String[] args) {
        int count = 10000000;
        test1(count);
        test2(count);
    }

    private static void test1(int count) {
        long l = System.currentTimeMillis();
        for (int i = 0; i < count; i++) {
            new PathPatternParser().parse("permission/test/{id}/test/{age}/{name}").matches(PathContainer.parsePath("permission/test/1/test/30/zhangsan"));
        }
        long e = System.currentTimeMillis();
        System.out.println(count+", PathPatternParser use totalTime:"+(e-l));
    }

    private static void test2(int count) {
        long l = System.currentTimeMillis();
        for (int i = 0; i < count; i++) {
             new AntPathMatcher().match("permission/test/{id}/test/{age}/{name}","permission/test/1/test/30/zhangsan");
        }
        long e = System.currentTimeMillis();
        System.out.println(count+", AntPathMatcher use totalTime:"+(e-l));
    }

性能差异：

10000000, PathPatternParser use totalTime:15977
10000000, AntPathMatcher use totalTime:69457

测试方案2：

static AntPathMatcher antPathMatcher = new AntPathMatcher();
    static PathPatternParser pathPatternParser = new PathPatternParser();
    public static void main(String[] args) {
        int count = 1000000;
        test2(count);
        test1(count);
    }

    private static void test1(int count) {
        long l = System.currentTimeMillis();
        for (int i = 0; i < count; i++) {
            pathPatternParser.parse("permission/test/{id}/test/{age}/{name}").matches(PathContainer.parsePath("permission/test/1/test/30/zhangsan"+i));
        }
        long e = System.currentTimeMillis();
        System.out.println(count+", PathPatternParser use totalTime:"+(e-l));
    }

    private static void test2(int count) {
        long l = System.currentTimeMillis();
        for (int i = 0; i < count; i++) {
            antPathMatcher.match("permission/test/{id}/test/{age}/{name}","permission/test/1/test/30/zhangsan"+i);
//            System.out.println(antPathMatcher.match("permission/test/{id}/test/{age}/{name}","permission/test/1/test/30/zhangsan"+i));;
        }
        long e = System.currentTimeMillis();
        System.out.println(count+", AntPathMatcher use totalTime:"+(e-l));
    }

1000000, AntPathMatcher use totalTime:1217
1000000, PathPatternParser use totalTime:1537、

结论：
建议使用AntPathMatcher 应为如果在匹配路径相同的情况下，AntPathMatcher具有更好的性能。并且有缓存。
