关于自定义标签报空指针异常："at org.apache.jasper.compiler.TldCache.getTaglibXml(TldCache.java:97) "

tomcat8对相对路径路径的不是很好。

可以在web.xml文件中设置好tld的路径，

然后JSP中直接<%@ taglib prefix="xia" uri="myTagLib" %>

web.xml文件添加以下配置：
<jsp-config>
    <taglib>
        <taglib-uri>myTagLib</taglib-uri>
        <taglib-location>/includes/tt.tld</taglib-location>
    </taglib>
</jsp-config>
