Question

package myPackage;   
 public class MyFormAuthenticator extends FormAuthenticator{

    //code lies here
    }

Web.xml文件

<web-app>
   ...
   <servlet>
    <servlet-name>myservlet</servlet-name>
    <jsp-file>/securedfile.jsp</jsp-file>
   </servlet>
   <servlet-mapping>
    <servlet-name>myservlet</servlet-name>
    <url-pattern>/secured</url-pattern>
   </servlet-mapping>
   <security-constraint>
      <web-resource-collection>
         <web-resource-name>SecuredBookSite</web-resource-name>
         <url-pattern>/secured/*</url-pattern>
            <http-method>GET</http-method>
            <http-method>POST</http-method>
      </web-resource-collection>

      <auth-constraint>
         <description>Let only managers use this app</description>
         <role-name>employee</role-name>
      </auth-constraint>
   </security-constraint>

   <security-role>
      <role-name>employee</role-name>
   </security-role>

   <login-config>
      <auth-method>FORM</auth-method>
      <form-login-config>
         <form-login-page>/login.jsp</form-login-page>
         <form-error-page>/error.jsp</form-error-page>
      </form-login-config>
   </login-config>
   ...
</web-app>

我读到context.xml文件应被编辑用于非默认用途。但是我不知道。我刚开始使用tomcat，所以我真的不知道要使用它。您可以对FormAuthenticator的工作方式进行一些解释吗？

我尝试过这样

context.xml

<Context docBase="Form_Auth1">
<Valve className  ="myPackage.MyFormAuthenticator"/>

</Context>

iam使用cmd编译Java类。 Tomcat版本：8.5 角色在Tomcat-users.xml中定义

请帮助
