java 汉字乱码问题解决方法
下面关于网页特效p/网页特效p.html target=_blank >jsp教程汉字乱码问题我们是做了一个过滤器，然后到web中配置一下，这样很好的解决了jsp中汉字编码问题哦。

public class characterfilter implements filter {

public void destroy() {

}

public void dofilter(servletrequest request, servletresponse response,
filterchain filter) throws ioexception, servletexception {

request.setcharacterencoding("utf-8");
response.setcharacterencoding("utf-8");
filter.dofilter(request, response);
}

public void init(filterconfig arg0) throws servletexception {

}

}

%>
再到 web配置中www.111com.net

characterfilter
org.shopping.uitl.characterfilter

再来看一下官方的对汉字乱码处理方法吧。mb.111com.net
