界: Input Validation and Representation

输入验证与表示问题是由元字符、交替编码和数字表示引起的。安全问题源于信任输入。这些问题包括：“Buffer Overflows”、“Cross-Site Scripting”攻击、“SQL Injection”等其他问题。

Struts: Unused Action Form

Abstract
未使用的操作表单表示应用程序逻辑可能并非处于最新状态。
Explanation
Struts 使用 form-bean 条目将 HTML 表单映射到操作。如果 Struts 配置文件的 <action-mappings> 元素不含与通过 <form-bean> 标签定义的相关操作表单对应的条目，应用程序逻辑可能并非处于最新状态。

示例 1：以下配置不含 bean2 映射。

<form-beans>
  <form-bean name="bean1" type="coreservlets.UserFormBean1" />
  <form-bean name="bean2" type="coreservlets.UserFormBean2" />
</form-beans>

<action-mappings>
  <action path="/actions/register1" type="coreservlets.RegisterAction1" name="bean1" scope="request" />
</action-mappings>
