struts2+spring+hibernate+json+jquery+flexigrid開發筆記-中文亂碼解決方法

     解決中文亂碼的方法有很多種,但個人認爲最有效最直接的方法就是過慮器,一次配置,多次使用,而且可以直接解決中文亂碼問題,在struts2下怎樣配置.

    過慮器代碼:

package com.popedom.uitl;

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;

/**
 *
 * @author Administrator
 */
public class SetCharacterEncodingFilter implements Filter {

    protected String encoding = null;
    protected FilterConfig filterConfig = null;
    protected boolean ignore = true;

    public void init(FilterConfig filterConfig) throws ServletException {
     
        this.filterConfig = filterConfig;
        this.encoding = filterConfig.getInitParameter("encoding");
        String value = filterConfig.getInitParameter("ignore");
        if (value == null) {
            this.ignore = true;
        } else if (value.equalsIgnoreCase("true")) {
            this.ignore = true;
        } else {
            this.ignore = false;
        }
    }

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
      
     System.out.println("o1111111111111111111111111ooo1ooooooooooo");
     if (ignore || (request.getCharacterEncoding() == null)) {
            String encoding = selectEncoding(request);
            if (encoding != null) {
                request.setCharacterEncoding(encoding);
            }
        }
        chain.doFilter(request, response);
    }

    public void destroy() {
        this.encoding = null;
        this.filterConfig = null;
    }

    protected String selectEncoding(ServletRequest request) {
        return (this.encoding);
    }
}
配置文件web.xml

 <filter>
        <filter-name>SetCharacterEncodingFilter</filter-name>
        <filter-class>com.popedom.uitl.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>
 <!-- --> <filter>
  <filter-name>struts2</filter-name>
  <filter-class>
   org.apache.struts2.dispatcher.FilterDispatcher
  </filter-class>
 </filter>

 <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>

 

這裏一定要注意不能把順序,先配置過慮器,在配置struts2,要不然會出現有時不出去亂碼,有時出現亂碼,具體原因尚未研究,等過一久忙玩這個項目,在好好總結一下解決亂碼問題的所有方法.
