持久化对象时,Hibernate编码错误[UTF-8]

Question

在持久化我的模型对象时,我面临着UTF-8编码问题.土耳其语' ı '是一封信.还有一些其他土耳其字符包含在UTF-8编码中.虽然我坚持我的模型对象,但所有' ı '字符都被保留为' ？'到DB.我在Ubuntu Linux 64位操作系统上使用MySQL 5.5.此外,我已经将hibernate&c3p0连接编码属性设置为UTF-8.当我调试时,来自客户端的数据是真的.

这是我的配置,如果有人可以帮助我,我会很高兴.

提前致谢.

Spring&Hibernate配置

    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource"><ref local="dataSource"/></property>
        <property name="packagesToScan" value="com.tk.dms.model" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.use_sql_comments">true</prop>
                <prop key="hibernate.format_sql">false</prop>

                <prop key="hibernate.generate_statistics">true</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
                <prop key="hibernate.connection.characterEncoding">UTF-8</prop>

尝试在数据源中设置编码

 <bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName">
        <value>com.mysql.jdbc.Driver</value>
    </property>
    <property name="url">
        <value>jdbc:mysql://127.0.0.1:3306/databaseName?characterEncoding=UTF-8</value>
    </property>
    <property name="username">
        <value>?</value>
    </property>
</bean>

您还确定来自表单的输入是否已正确编码？你在弹簧应用中使用过滤器吗？在调试模式下运行应用程序并在持久化之前检查模型对象的字段.

过滤器应放在web.xml文件中:

<filter>
    <filter-name>SetCharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>SetCharacterEncodingFilter</filter-name>
    <url-pattern>*</url-pattern>
</filter-mapping>
