The small method of solving garbled characters in the development of JS and Java EE

1, set up Httpservletresponse.setcontexttype ("text/html; Charset=utf-8");

2, in the Web page with encodeURIComponent () to encode the query string. Httpservletrequest.getparameter (name) is substituted for special characters. (such as: +) automatically replaced with "" (Blank string).

3, in the query string transmission, as far as possible to the Base64 encoding, reduce the network traffic. After Base64 encoding, the encodeURIComponent () encoding must be performed. Because there is a special character "+" in the Base64 encoding, it is automatically replaced.

4, the IDE's environment as far as possible also defined as utf-8. Is consistent with the encoding of the page and the encoding of the database.

This can basically solve the JS and Java development in the garbled problem.
