Spring Security Login issue

问题:

I am new to Spring Security and have configured Spring Security in my Spring MVC application.

After submission of login page, I am getting the following error

The requested resource (/j_spring_security_check) is not available.

I am not able to understand this behaviour.

Please help.

spring-security.xml

<security:http auto-config="true" use-expressions="true" access-denied-page="/appln/denied">
    <security:intercept-url pattern="/appln/login" access="permitAll" />
    <security:intercept-url pattern="/appln/index" access="hasRole('ROLE_ADMIN')" />
    <security:intercept-url pattern="/appln/run" access="hasRole('ROLE_ADMIN')" />
    <security:intercept-url pattern="/appln/common" access="hasRole('ROLE_USER')" />

    <security:form-login login-page="/appln/login"
                         authentication-failure-url="/appln/login?error=true"
                         default-target-url="/appln/run"
                         authentication-success-handler-ref="AuthHandlr" />

    <security:logout invalidate-session="true"
                     logout-success-url="/appln/login" 
                     delete-cookies="JSESSIONID" />
</security:http>

回答1:

Solved the issue.

In my loginpage.jsp , the action attribute was defined as

action=../../j_spring_security_check

I was playing with the above and changed it to

action = /j_spring_security_check

and it worked without any issues.

Although the issue is solved , can anybody please elaborate on why did the change in the path work.

回答2:

The form action can be 'j_spring_security_check' or '/j_spring_security_check'.

This is a default in Spring-Security can not be changed.

Similarly the form fields have to be 'j_username' and 'j_password'
