public class RegistAction extends Action {
@Override

HttpServletRequest request, HttpServletResponse response)
throws Exception {
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
UserForm userForm = (UserForm) form;
String username = userForm.getUser().getUsername();
//解决用户名乱码
byte[] b = username.getBytes("iso-8859-1");//先回去使用iso的错误字符串
username = new String(b,"UTF-8");//（iso）回退，使用utf-8重编
userForm.getUser().setUsername(username);
String[] like = userForm.getUser().getLike();
for(int i=0;i<like.length;i++){
byte[] like1 = like[i].getBytes("iso-8859-1");//先回去使用iso的错误字符串
like[i] = new String(like1,"UTF-8");//（iso）回退，使用utf-8重编
}
userForm.getUser().setLike(like);
ActionMessages errors = new ActionMessages();
if(userForm.getUser().getUsername().trim().equals("aaa")){
errors.add("errname",new ActionMessage("err.repeated","用户"));
//this.saveErrors(request, errors);
//return mapping.getInputForward();
}
if(!this.isTokenValid(request)){//加入Token无效，例如Session属性中没有Token
//添加错误信息
errors.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage("表单重复提交",false));
}
if(!errors.isEmpty()){
this.saveErrors(request, errors);
//跳转到错误页面
return mapping.getInputForward();
}
//如果Token有效即Session域中有Token则移除Session域中的Token，然后转到成功页面
this.resetToken(request);
return mapping.findForward("success");
}
}
在Action的execute方法中，对Form进行了转型为UserForm，然后对UserForm进行的编码转换是怎么影响到session域中的Form的呢？
你把 struts的配置 和 jsp 都贴下吧
