错误:
/chentao/echart-biao-pan.jsp (line: 12, column: 1) Page directive: illegal to have multiple occurrences of contentType with different values (old: text/html; charset=UTF-8, new: text/html;charset=UTF-8)
- 不允许contentType="text/html; charset=UTF-8",有空格。
之前错误写法为:<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
正确写法为:<%@ page language="java" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"%>
2.在我的jsp页面(A页面)有引入其他的jsp页面(B页面),两个页面的抬头不相同导致的错误。
A页面:<%@ page contentType="text/html;charset=UTF-8" language="java" %>
B页面:<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
我的A页面contentType="text/html;charset=UTF-8"。“;”号后面没有空格。B页面contentType="text/html; charset=UTF-8",“;”后面有空格。我将A页面的text/html与charset=UTF-8中间加上空格和B页面一样时就没有报错了。
