How to encode special characters for POST using Spring / Roo

Question

I use Spring / Roo for the application server and should be able to send some special characters. In particular, symbols such as the yen symbol, or the euro symbol. When I receive these characters on my server and display them on the console, they are displayed as "?". How can they be correctly encoded and received?

Answer 1

There are a couple of possible points of failure.

First I checked if the console supports the corresponding characters:

• , JVM, , System.out
• ,
• , System.out,

, , int - Unicode charts.

. UTF-8 . , , , ; , GET ( ). Accept-Charset header, ( Firebug Fiddler). Roo, - .

database.url=jdbc:mysql://[YOUR_DB_SERVER]:3306/[YOUR_DB_NAME]?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8
