struts乱码处理(利用过滤器)

搞了好久,调试发现乱码主要出现在formbean中,所以写一个类进行转码就行,写一个类进行转码，如
package lmj.zdsoft.efforts.filter;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.RequestProcessor;

public class Filter extends RequestProcessor {

 public Filter() {
 }

 protected boolean processPreprocess(HttpServletRequest request,
   HttpServletResponse response) {

  try {
   request.setCharacterEncoding("UTF-8");//与页面相同

  } catch (Exception ex) {
   System.out.println("字符集设置失败");

  }

  return true;
 }

}

然后在struts-config.xml里加上
<controller processorClass="lmj.zdsoft.efforts.filter.Filter" />
这样就不会出现乱码了
