How to display arabic correctly in Spring JSF MySQL application?
Frage
i am using spring 3, JSF 2 , MYSQL, Hibernate, and Heidi SQL is the GUI tool for the database
and i am having an encoding problem with Arabic characters is that Arabic words is inserted in the database as ??????????
and appears in the view in the same form.
so here's my encoding configuration:
1- Database:
Character set: utf 8
Collation: utf8_general_ci
2- Spring:
i am using the following filter:
<filter>
<filter-name>encoding-filter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding-filter</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
3- JSF:
As far as i know: Facelets uses UTF-8
by default.
4- Hibernate:
here's the connection url for the database:
jdbc:mysql://127.0.0.1:3306/mydb?zeroDateTimeBehavior=convertToNull&useUnicode=true&connectionCollation=utf8_general_ci&characterSetResults=utf8
please advise if i am missing something in the configuration.
Lösung
You forgot the characterEncoding=UTF-8
parameter in your JDBC URL. Here's the revised JDBC URL with the minimum required parameters to let it handle UTF-8 properly:
jdbc:mysql://127.0.0.1:3306/mydb?useUnicode=true&characterEncoding=UTF-8

if you use tomcat you will need to add the following argument to configuration Arguments:
-Dfile.encoding=UTF-8
in addition to the above hibernate configuration.
