Character-encoding problem spring

Question

I am stuck in a big problem with encoding in my website! I use spring 3, tomcat 6, and mysql db. I want to support German and Czech along with English in my website, I creat

Answer 1

1: By default the messages.properties (Czech) should load, instead the messages_en.properties loads by default.

I don't do Spring, so here's a shoot in the dark: maybe because English is ordered first and/or your platform/browser uses English as default locale? Rearrange the configuration and check accept-language in the HTTP request header to exclude one and other.

2: In the web form, when I enter Czech data, then click submit, in the Controller I print out the data in the console before to save it to db, what's being printed is not correct having strange chars, and this is the exact data that saves to db.

Is the console configured to use UTF-8 to display data? It would use the platform default encoding otherwise. In for example Eclipse you can configure it by Window > Preferences > General > Workspace > Text File Encoding.

Is the data access layer configured properly to handle the data as UTF-8? MySQL JDBC driver is known to be a bit non-smart in this. It won't use the DB-specified encoding, but the client platform default encoding. To the point, you'd like to use the useUnicode=true and characterEncoding=UTF-8 properties in the JDBC connection string. E.g.

jdbc:mysql://localhost/some_db?useUnicode=yes&characterEncoding=UTF-8
