How to get the exact client browser name and version in Spring MVC?

Question

I'm working on a Spring MVC application, and I need to access client browser name and version.

I have an instance of HttpServletRequest in my action as a parameter and use request.getHeader("User-Agent") method, but this returned Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko in Internet explorer 9.

I need to exact number and version. Is there any tools for doing that?

There is no safe way to do it. The browser name and version comes from the browser (the _client_). It can be easily spoofed, so you can't be 100% sure to have the correct name and version of the browser — BackSlash, Feb 04 '15 at 13:55

Acknowledging that the user agent is unsafe. Still, in the lack of other ways, you should parse a user-agent header, which in fact is not as easy, as the number of combinations is overwhelming. Unless you want to roll your own, I would suggest

http://www.bitwalker.eu/software/user-agent-utils

source is available at

https://github.com/HaraldWalker/user-agent-utils

the usage is quite straightforward

UserAgent userAgent = UserAgent.parseUserAgentString(request.getHeader("User-Agent"));
System.out.println(userAgent.getBrowser().getName() + " " + userAgent.getBrowserVersion());

You can also take a look at another library, [Browscap](https://github.com/browscap/browscap/wiki/Using-Browscap). – mojtab23 Aug 15 '18 at 06:15
