J2EE Misconfiguration: Missing Filter Definition

Abstract
不应用引用不存在的筛选器的筛选器映射。
Explanation
每个筛选器映射必须与有效筛选器定义对应才能应用。

示例 1：以下示例显示了引用不存在的筛选器 AuthenticationFilter 的筛选器映射。由于缺少定义，筛选器 AuthenticationFilter 不会应用于指定的 URL 模式 /secure/*，而且可能导致运行时异常。

<filter>
    <description>Compresses images to 64x64</description>
    <filter-name>ImageFilter</filter-name>
    <filter-class>com.ImageFilter</filter-class>
</filter>

<!-- AuthenticationFilter is not defined -->
<filter-mapping>
    <filter-name>AuthenticationFilter</filter-name>
    <url-pattern>/secure/*</url-pattern>
</filter-mapping>

<filter-mapping>
    <filter-name>ImageFilter</filter-name>
    <servlet-name>ImageServlet</servlet-name>
</filter-mapping>
