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.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>
=============================================
SetEncodeFilter.java
public class SetEncodeFilter implements Filter {
protected FilterConfig filterConfig = null;
protected String defaultEncoding = null;
/* (non-Javadoc)
* @see javax.servlet.Filter#init(javax.servlet.FilterConfig)
*/
public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
this.filterConfig = arg0;
this.defaultEncoding = filterConfig.getInitParameter("defaultencoding");
}
/* (non-Javadoc)
* @see javax.servlet.Filter#doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse, javax.servlet.FilterChain)
*/
public void doFilter(
ServletRequest request,
ServletResponse response,
FilterChain chain)
throws IOException, ServletException {
// TODO Auto-generated method stub
request.setCharacterEncoding(selectEncoding(request));
chain.doFilter(request, response);
}
public void destroy() {
this.defaultEncoding = null;
this.filterConfig = null;
}
protected String selectEncoding(ServletRequest request) {
return this.defaultEncoding;
}
}
另需注意的是数据库, 表, 字段的字符集是否也正确!
alert database DBNAME character set=utf8
