struts1.x中文乱码解决

使用过滤器Filter过滤struts1的中文乱码

第一步：先设定jsp页面或html页面的编码

jsp:<%@ page language="java" contentType="text/html" pageEncoding="UTF-8"%>
html:<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">

第二步：我们来看看web文件的配置

  <filter>       
      <filter-name>characterEncodingFilter</filter-name>       
      <filter-class>hr.util.CharacterEncodingFilter</filter-class>   
      <init-param>   
      <param-name>encoding</param-name>   
      <param-value>UTF-8</param-value>   
      </init-param>   
      <init-param>   
      <param-name>enable</param-name>   
      <param-value>true</param-value>   
      </init-param>   
   </filter>   
   <filter-mapping>       
    <filter-name>characterEncodingFilter</filter-name>       
    <servlet-name>action</servlet-name>     
  </filter-mapping>   
  

第三步：生成Filter文件

package hr.util;    
   
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 CharacterEncodingFilter implements Filter {    
  private FilterConfig filterConfig;    
   
  private String encoding;    
   
  private boolean enable;    
   
  public CharacterEncodingFilter() {    
    encoding = "UTF-8";    
    enable = false;    
  }    
   
  public void init(FilterConfig filterConfig) throws ServletException {    
    this.filterConfig = filterConfig;    
    loadConfigParams();    
  }    
   
  private void loadConfigParams() {    
    encoding = filterConfig.getInitParameter("encoding");    
    String strIgnoreFlag = filterConfig.getInitParameter("enable");    
    if (strIgnoreFlag.equalsIgnoreCase("true")) {    
      this.enable = true;    
    } else {    
      this.enable = false;    
    }    
  }    
   
  public void doFilter(ServletRequest request, ServletResponse response,    
      FilterChain chain) throws IOException, ServletException {    
    if (enable) {    
      request.setCharacterEncoding(encoding);    
    }    
    chain.doFilter(request, response);    
  }    
   
  public void destroy() {    
    filterConfig = null;    
    encoding = null;    
  }    
}    

通过以上的方法，在struts中就再也不用担心乱码问题了，也不用再在每个页面中写  request.setCharacterEncoding("UTF-8")了
