springframework'form'标签+ spring security auth

Question

我想要什么。我想通过springframework标签'form'来执行spring security auth。 实施例

<!-- JSP -->
<form:form action="login" commandName="?" >
 <form:errors path="lastError" ></form:errors>
 <form:input path="j_username" />
 <form:password path="j_password" />
 <form:button value="submit" name="submit" />
</form:form>

<!-- security-context.xml -->
<http use-expressions="true">
  <intercept-url pattern="/client/**" access="hasRole('ROLE_USER')" />
  <form-login login-page="/login" login-processing-url="/login"
    authentication-failure-handler-ref="authHandler" />
  <logout logout-url="/logout" logout-success-url="/" />
</http>

应该是什么而不是“？”在表单commandName或我如何做这个狡猾的行动？ Thanx任何建议。
