正则表达式以匹配网址格式

Question

I know this is a very simple question but since I am very bad in regex , have to ask below question. I want to write a regex expression in java which will match below two url patterns given :

{contextPath}/javax.faces.resource/**

{contextPath}/rfRes/**

The url will be read from http request object and will be compared using java pattern object like below :

Pattern p = //regex here ;
p.matcher(r.getRequestURL().toString()).matches(); 

Can anybody help me in writing a regex experion for above two urls ?

Answer 1

you can use this :

.*?(?:\/javax\.faces\.resource\/|\/rfRes\/).*$

demo here : http://regex101.com/r/rV5mR8/2

It checks whether the string start with either of the two options which you want.

Answer 2

您可以使用此：

boolean matches = r.getRequestURI().matches(".*?/(javax\.faces\.resource|rfRes)/.*");
