Hibernate + MySQL Chinese problem solution.

1. Set the character set UTF-8 during MySQL installation. The JDBC driver is later than 3.0.15.

2. Add attributes to the hibernate configuration file.

<Property name = "connection. useunicode"> true </property>

<Property name = "connection. characterencoding"> UTF-8 </property>

3. Set filter in Web. xml

========================================================== ==========
<Filter>

<Filter-Name>

Set web application character encoding

</Filter-Name>

<Filter-class> cn.com. commnet. util. setencodefilter </filter-class>

<Init-param>

<Param-Name> defaultencoding </param-Name>

<Param-value> UTF-8 </param-value>

</Init-param>

</Filter>

<Filter-mapping>

<Filter-Name>

Set web application character encoding

</Filter-Name>

<URL-pattern>/* </url-pattern>

</Filter-mapping>
