jsp辨认不出程序中的中文

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

39: String title = null;
40: List departList = null;
41:

43: title = "鎼滅储缁撴灉";
44: departList = new ArrayList();
45: Depart depart = (Depart) request.getAttribute(GET_SEARCH_RESULT);

编码问题，把IOS变成utf_8

右键你的工程
点击properties
点击resource
修改你的text file encoding为utf-8看看是不是解决了
如果没有，做完上述操作后，删除乱码重新打一遍就好啦
