Make UTF-8 available to host arabic data in Mysql DB using Spring

Hello everyone, I want to put arabic data with my code into mysql database in my webApp:

the technologies i used: Spring MVC / Hibernate:

its my code in my logical Busines part:

 transaction.setExplaination("Something with Arabic alphabet");
 ..
 ..
 getHibernateTemplate().saveOrUpdate(transaction);

      

        
        
        
      

    

when i get the explanation for my transaction and display it in the .jsp page it was shown as ?????? and his problem.

in mvc-dispatcher-servlet.xml:

at first i used it:

  <bean id="driverManagerDataSource"   class="org.springframework.jdbc.datasource.DriverManagerDataSource">
     <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
     <property name="url" value="jdbc:mysql://localhost:3306/DB_Name?useUnicode=true&characterEncoding=UTF-8"/>
     <property name="username" value="root"/>
     <property name="password" value="myjava123"/>

</bean>

      

        
        
        
      

    

but this throws an error for my xml, so i delete it.

I used org.springframework.web.filter.CharacterEncodingFilter in my web.xml:

 <filter>
    <filter-name>encodingFilter</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>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

      

        
        
        
      

    

but also no difference in results

I would be grateful if someone could show me how it works.
