Hibernate+mysql 中文问题解决方案.

1. mysql安装时设置字符集utf-8, jdbc驱动3.0.15以上.
2. hibernate配置文件中,加上属性
<property name="connection.useUnicode">true</property>
<property name="connection.characterEncoding">UTF-8</property>

3. web.xml设置Filter
=================================================
<filter>
<filter-name>
Set Web Application Character Encoding
filter-name>
<filter-class>cn.com.commnet.util.SetEncodeFilterfilter-class>
<init-param>
<param-name>defaultencodingparam-name>
<param-value>UTF-8param-value>
init-param>
filter>
<filter-mapping>
<filter-name>
Set Web Application Character Encoding
filter-name>
<url-pattern>/*url-pattern>
filter-mapping>

=============================================
