数据库块取出的时候按你写的处理下.就OK.
我做的是这样的,关键是MySql的编码问题
具体什么问题,要具体解决的。
你提的太笼统了,不知从何说了
property="driverClassName"
value="org.gjt.mm.mysql.Driver" />
<set-property
property="url"
value="jdbc:mysql://localhost/deoa?useUnicode=true&useUnicode=true&characterEncoding=GBK" />
连接串要这样配置
错误最重要的一点就是
重复定义.
1.将资源文件编成ASCII码
2.所有JSP页面都改成<%@ page ContentType="text/html;charset=UTF-8"%>
无须这个response.setContentType("text/html;charset=UTF-8")
3.设置过滤器,参考代码
package bbs.filter;import javax.servlet.Filter;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.FilterChain;
import java.io.IOException;public class SetCharacterFilter implements Filter {
public void init(FilterConfig filterConfig) throws ServletException { }
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
request.setCharacterEncoding("UTF-8");
chain.doFilter(request,response);
}
public void destroy() { }
}4.在Web.xml文件中设置过滤器
<filter>
<filter-name>CharsetFilter</filter-name>
<filter-class>bbs.filter.SetCharacterFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CharsetFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
5.所有的提交到数据库中的记录"没有必要"去设置成
new String(iso.getBytes("ISO-8859-1"), "GBK")
6.这样输入和输出统一用"UTF-8"码,就没问题了,对了,过滤器里面一定要用UTF-8喔!!
