关于struts2中的显示页面乱码问题

大多数时候我们在所有JSP页面中添加



<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

是可以解决页面乱码问题的，不行还可以通过在servlet过滤器中编写代码解决，例如：

package com.mingrisoft;

import java.io.IOException;

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import javax.servlet.annotation.WebFilter;

import javax.servlet.annotation.WebInitParam;

@WebFilter(

  urlPatterns = { "/*" },

  initParams = {

    @WebInitParam(name = "encoding", value = "UTF-8")

  }) 

public class CharactorFilter implements Filter {

 String encoding = null;         

    public CharactorFilter() {

    }

 public void destroy() {

  encoding = null;

 }

 public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

  if(encoding != null){        

   request.setCharacterEncoding(encoding);   

       response.setContentType("text/html; charset="+encoding);

  }

  chain.doFilter(request, response);     

 }

 public void init(FilterConfig fConfig) throws ServletException {

  encoding = fConfig.getInitParameter("encoding"); 

 }

}

但是在运用strus2框架的程序中若不采用servletFilter的情况下，可以在web.xml文件下配置如下代码：

<filter-name>SetCharacterEncodingFilter</filter-name>

 <filter-class> cn.cublog.jedliu.SetCharacterEncodingFilter </filter-class>

  <init-param>

  <param-name>encoding</param-name>

   <param-value>UTF-8</param-value>

   </init-param>

    </filter>

 

<filter-mapping>

<filter-name>SetCharacterEncodingFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

以上代码默认读者能够看懂，未添加注释，如果有不懂的地方欢迎私聊，希望对你们有帮助^-^
