jsp用过滤器解决中文乱码问题的方法
定义一过滤器，实现Filtter接口
publicclassEncodingFilterimplementsFilter{
@Override
publicvoiddestroy(){
//TODOAuto-generatedmethodstub
}
@Override
publicvoiddoFilter(ServletRequestreq,ServletResponseresp,
FilterChainchain)throwsIOException,ServletException{
//TODOAuto-generatedmethodstub
HttpServletRequestrequest=(HttpServletRequest)req;
HttpServletResponseresponse=(HttpServletResponse)resp;
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=UTF-8");
chain.doFilter(req,resp);
}
@Override
publicvoidinit(FilterConfigfilterConfig)throwsServletException{
//TODOAuto-generatedmethodstub
}
}
web.xml文件中，配置过滤器
<filter> <filter-name>EncodingFilter</filter-name> <filter-class>pers.filter.EncodingFilter</filter-class> </filter> <filter-mapping> <filter-name>EncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
