JSP sets file encoding, jsp sets Encoding

JSP sets file encoding, jsp sets Encoding

1 <% @ page language = "java" contentType = "text/html; charset = UTF-8" pageEncoding = "UTF-8" %> 2 <! DOCTYPE html PUBLIC "-// W3C // dtd html 4.01 Transitional // EN" http://www.w3.org/TR/html4/loose.dtd "> 3  
Differences between contentType and pageEncoding encoding:
 

 
 
 
  
PageEncoding refers to the encoding of JSP files, while charset in contentType refers to the content encoding sent from the server to the client.
 
 
  
In JSP, if pageEncoding exists, the JSP encoding will be determined by pageEncoding, otherwise it will be determined by the charset attribute in contentType; if both do not exist, the encoding method of the ISO-8859-1 will be used.
 
 
  
In JSP, all content has to go through two encoding operations, the first stage will use pageEncoding encoding, the second stage will use UTF-8 encoding, the third stage is Tomcat generated web page, in this case, contentType is used.
