Garbled problems encountered in web development

I believe that everyone in the web development will encounter garbled problems, there are page garbled, request garbled, database garbled, and so on, here I enumerate the different cases of garbled solution:

1. The corresponding data garbled:

Just write the phrase in the background interface method to specify that the response character set is Utf-8
Response.setcontenttype ("Text/html;charset=utf-8");

2. Request data garbled:

①.get Request:

The first way the Tomcat default character set is Iso8859-1, you can manually convert it to the desired character set, manually transcoding;

The second way, configure the filter, use filter;

Third Way, directly modify the Tomcat configuration

<port= "8080"  protocol= "http/1.1"               connectiontimeout  = "20000"               redirectport= "8443"  uriecoding= "UTF-8" />

②post Request:

Request.setcharacterencoding ("Utf-8")

3. Database garbled:

Jdbc:useunicode=true&characterencoding=utf-8 create table  xxx () engine  Default Charset=utf-8

4.html file

<charset= "Utf-8">

5. Project code set to Utf-8
