web.xml 的虚假 Eclipse 警告:“未检测到文档的语法约束(DTD 或 XML 模式)." [英] Bogus Eclipse warning for web.xml: "No grammar constraints (DTD or XML schema) detected for the document."

问题描述

我的 web.xml 文件的顶部如下所示:

The top of my web.xml file looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_5.xsd"
    version="2.5">

但我仍然收到来自 Eclipse (Ganymede) 的警告，即未检测到 XML 模式，并且没有警告模式违规.我项目中的其他 XML 文件(例如 Spring Framework 配置文件)没有警告，并且确实给出有关架构违规的正确警告.

But I still get the warning from Eclipse (Ganymede) that no XML schema is detected, and schema violations are not being warned about. Other XML files in my project (Spring Framework configuration files for example) don't have the warning and do give correct warnings about schema violations.

如何使架构检查正常工作并希望警告消失?服务器运行正常.这似乎是一个 IDE 问题.

How do I get the schema checking working and hopefully the warning to go away? The server does run correctly. It just appears to be an IDE issue.

推荐答案

或许可以试试:

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd

代替:

http://java.sun.com/xml/ns/j2ee/web-app_2_5.xsd

另外，<!DOCTYPE ...> 也不见了:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
<web-app
  xmlns="http://java.sun.com/xml/ns/j2ee" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
  version="2.5">
  <!-- ... -->
</web-app>
