jsp中的中文辨认为乱码
if(op.equals(OP_SEARCH)||op.equals(OP_EDIT_SUB)||op.equals("add_sub")){
title = "搜索结果";
departList = new ArrayList();
Depart depart = (Depart) request.getAttribute(GET_SEARCH_RESULT);
departList.add(depart);
}
在网页中显示
org.apache.jasper.JasperException: An exception occurred processing JSP page /authority/depart/DepartManage.jsp at line 42

40: List departList = null;

主要是编码对中文支持受限导致的，你搜一下 utf-8，把这个嵌到你的程序里呢~
