未检测到 taglib 文件中的文档的语法约束(DTD 或 XML 模式) [英] No grammar constraints (DTD or XML schema) detected for the document in a taglib file

问题描述

日食伽利略

<?xml version="1.0" encoding="UTF-8"?>
<taglib xmlns="http://java.sun.com/xml/ns/javaee"
        xmns:xsi="http://www.w3.org/2001/XMLSchema-instance"         
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee/webjsptaglibrary_2_0.xsd" 
        version="2.0">
</taglib>

我怎样才能摆脱警告?应用程序工作正常，看起来像是 IDE 问题或什么的.我知道我可以禁用警告检查，但这并不是我正在寻找的.

How can I get rid of the warning? Application works fine, looks like an IDE issue or something. I am aware of that I can disable warning checks but this is not exactly what I am looking for.

推荐答案

更改:

 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee/webjsptaglibrary_2_0.xsd"

到

 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/webjsptaglibrary_2_0.xsd"

确保 xsd 可通过 http://java.sun.com/xml/ns/javaee/webjsptaglibrary_2_0.xsd在这种情况下它不可用.

Be sure that xsd is available by http://java.sun.com/xml/ns/javaee/webjsptaglibrary_2_0.xsd In this case it unavailable.
