[struts]使用過濾器設置字符集實現中文數據的提交

//建立過濾器類：

package cn.java;

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 he
 */
public class CharacterEncodingFilter implements Filter{

    public void init(FilterConfig arg0) throws ServletException {
     System.out.println("CharacterEncodingFilter");
    }

    public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain arg2) throws IOException, ServletException {
      arg0.setCharacterEncoding("UTF-8");
      arg2.doFilter(arg0, arg1);
    }

    public void destroy() {
        throw new UnsupportedOperationException("Not supported yet.");
    }

}
