web.xml 增加编码过滤器
<filter>
<filter-name>encoding</filter-name>
<filter-class>
com.skysz.framework.filter.encoding.EncodingFilter
</filter-class>
</filter>

EnCodingFilter 实现类
public class EncodingFilter implements Filter {
private String encoding;
public void init(FilterConfig config) throws ServletException {
this.encoding = config.getInitParameter("encoding");
if (StringUtils.isNullOrBlank(this.encoding)) {
this.encoding = "UTF-8";
}

}
public void doFilter(ServletRequest srequest, ServletResponse sresponse, FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) srequest;
request.setCharacterEncoding(encoding);
chain.doFilter(srequest, sresponse);
}

public void destroy() {
}
}

你是通过什么把值传过来的 action还是servlet
action的话在里面添加ServletActionContext.getResponse().setCharacterEncoding("UTF-8");
servlet的话获取HttpResponse对象执行setCharacterEncoding("UTF-8");追问

">

这个是代码，还是乱码？

追答同学你按别人的答案走然后问我怎么回事木有这么玩的

response.setCharacterEncoding("UTF-8");

放在request.getParameter()前面
