J2EE Misconfiguration: Missing Servlet Mapping

Java/JSP

Abstract

除非具有相应的 Servlet 映射，否则无法访问 web.xml 中定义的 Servlet。

Explanation

缺少有效 Servlet 映射会阻止对未映射的 Servlet 的所有访问。

示例 1：web.xml 中的以下条目可定义 ExampleServlet，但无法定义相应的 Servlet 映射。


<web-app
    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_4.xsd"
    version="2.4">

    <servlet>
      <servlet-name>ExampleServlet</servlet-name>
      <servlet-class>com.class.ExampleServlet</servlet-class>
      <load-on-startup>1</load-on-startup>
    </servlet>

</web-app>
