How to handle special characters in path variables

Question

I am taking variable names from a path variable in my spring application.

However that fails in some cases when URL contains special characters

For eg http://www.loudletters.com/ll/rest/celebrityprofile/2S/Jan%20Min%C3%83%C2%A1%C3%85%C2%99 gives page not found error.

How to handle this?

Answer 1

I handle UTF-8 path variables just fine. What you need to do is:

• set UTF-8 for URIs in your servlet container configuration
• read the input as utf-8 (probably using spring's CharacterEncodingFilter )

The encoding and decoding should be done automatically by the servlet container and the browser.

您是否考虑过使用java.net.URLDecoder和java.net.URLEncoder ？
