乱码解决

方法一：

public static String changeStr(String str){
  try {
   str = new String(str.getBytes("ISO-8859-1"),"GBK");
  } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  return str;
 }

 
 方法二：

1.Strut配置文件

<controller processorClass="com.lib.processor.EncodingProcessor" /> 

2.重写EncodingProcessor

public class EncodingProcessor extends RequestProcessor {

 public void process(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException {
  
  request.setCharacterEncoding("gbk");
  response.setContentType("text/html;charset=gbk");
  super.process(request, response);
 }
}
