XML 验证缺少标签

Question

这些 xml 验证结果究竟代表什么？

“nbres:/org/netbeans/modules/j2ee/ddloaders/catalog/resources/datatypes.dtd”中的引用实体。 cvc-complex-type.2.4.a：发现以元素“过滤器名称”开头的无效内容。 '{"http://java.sun.com/xml/ns/javaee":description, "http://java.sun.com/xml/ns/javaee":display-name, "http:// /java.sun.com/xml/ns/javaee":icon, "http://java.sun.com/xml/ns/javaee":servlet-name}' 是预期的。 [48] 元素类型“servlet”必须由匹配的结束标记“”终止。 [50] XML 验证完成。

我对这些不太熟悉！

Answer 1

这个xml是你手动编码的吗？

错误消息告诉您 XML 根据其预期的架构无效：

1. 你有<filter-name>，它期待<description>、<display-name>、<icon>或<servlet-name>之一。
2. 您的</servlet> 标签（或者可能是开头的<servlet>）似乎放错了位置

编辑：我在 Oxygen 中加载了 XML，看起来 <servlet> 的问题实际上是因为 <filter> 标记放错了位置。

Answer 2

今天我遇到了类似的错误。我的代码如下所示：

<servlet>
    <init-param>
        <param-name>data1</param-name>
        <param-value>value1</param-value>
    </init-param>
    <init-param>
        <param-name>data2</param-name>
        <param-value>value2</param-value>
    </init-param>
    <servlet-name>ServletConfigServlet</servlet-name>
    <servlet-class>com.netease.server.example.web.controller.ServletConfigServlet</servlet-class>
</servlet>

错误警告：

cvc-complex-type.2.4.a: Invalid content was found starting with element 'init-param'. 
One of '{"http://java.sun.com/xml/ns/javaee":description,
"http://java.sun.com/xml/ns/javaee":display-name,
"http://java.sun.com/xml/ns/javaee":icon,
"http://java.sun.com/xml/ns/javaee":servlet-name}' is expected.

我已经尝试了一些解决方案。最后，我通过更改了 <init-param> 和<servlet-name>, <servlet-class> 的顺序来修复它。它看起来像：

<servlet>
    <servlet-name>ServletConfigServlet</servlet-name>
    <servlet-class>com.netease.server.example.web.controller.ServletConfigServlet</servlet-class>
    <init-param>
        <param-name>data1</param-name>
        <param-value>value1</param-value>
    </init-param>
    <init-param>
        <param-name>data2</param-name>
        <param-value>value2</param-value>
    </init-param>
</servlet>

希望这可以帮助某人。 :D
