Java – configure spring security to use custompasswordauthenticationfilter

I have implemented my own lowercaseusernamepasswordauthenticationfilter, which is just a subclass of usernamepasswordauthenticationfilter

But now my question is how to configure spring security to use this filter

So far, I have used:

<security:http auto-config="true" use-expressions="true">
    <security:form-login login-processing-url="/resources/j_spring_security_check" login-page="/login" authentication-failure-url="/login?login_error=t" />
    <security:logout logout-url="/resources/j_spring_security_logout" />

    <security:intercept-url pattern="/**" access="isAuthenticated()" requires-channel="${cfma.security.channel}" />
</security:http>

Do I really want to turn on automatic configuration? Do I need to manually configure all filters If this is true, can anyone provide an example?

How to add simple security: custom filters:

<security:http ...>

   <security:form-login login-processing-url="/resources/j_spring_security_check" login-page="/login" authentication-failure-url="/login?login_error=t" />
   <security:custom-filter ref="lowerCaseUsernamePasswordAuthenticationFilter" position="FORM_LOGIN_FILTER"/>
   ...
 </security:http>

The exception that did cause the message:

Solution

I have done this by manually writing the required auto - configured beans This is the result:

<!-- HTTP security configurations -->
<security:http auto-config="false" use-expressions="true" entry-point-ref="loginUrlAuthenticationEntryPoint">

    <!--
    <security:form-login login-processing-url="/resources/j_spring_security_check" login-page="/login" authentication-failure-url="/login?login_error=t" />
        replaced by lowerCaseUsernamePasswordAuthenticationFilter
        the custom-filter with position FORM_LOGIN_FILTER requries that auto-config is false!
     -->
    <security:custom-filter ref="lowerCaseUsernamePasswordAuthenticationFilter" position="FORM_LOGIN_FILTER"/>
    <security:logout logout-url="/resources/j_spring_security_logout" />

    <security:intercept-url pattern="/**" access="isAuthenticated()" />
</security:http>

<bean id="loginUrlAuthenticationEntryPoint" class="org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint">
    <property name="loginFormUrl" value="/login"/>
</bean>

<bean id="lowerCaseUsernamePasswordAuthenticationFilter"
    class="com.queomedia.cfma.infrastructure.security.LowerCaseUsernamePasswordAuthenticationFilter">
    <property name="filterProcessesUrl" value="/resources/j_spring_security_check"/>
    <property name="authenticationManager" ref="authenticationManager"/>
    <property name="authenticationFailureHandler">
        <bean class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler">
            <property name="defaultFailureUrl" value="/login?login_error=t"/>       
        </bean>
    </property>
</bean>
