        model.addAttribute("serverTime", formattedDate );

        return "login";
    }

}

please help me to resolve this.

Answer 1

I believe the order of intercept-url is important here, and it seems like your /** pattern is swallowing /login and /resources too.

Try this:-

<http pattern="/resources/**" security="none"/>
<http pattern="/login" security="none"/>

<http use-expressions="true">
    <form-login login-processing-url="/resources/j_spring_security_check"
        login-page="/login" authentication-failure-url="/login?login_error=t" />
    <logout logout-url="/resources/j_spring_security_logout" />
    <intercept-url pattern="/**" access="isAuthenticated()" />
</http>

This configuration is very similar to one of my existing projects.

UPDATE

This is the configuration I'm currently using in my project:-

<security:http pattern="/resources/**" security="none"/>
<security:http pattern="/login" security="none"/>
<security:http pattern="/error/**" security="none"/>

<security:http auto-config="true">
    <security:form-login login-page="/login"
                         authentication-failure-url="/login?login_error=1"
                         default-target-url="/"
                         always-use-default-target="true"/>
    <security:logout logout-success-url="/"/>
    <security:intercept-url pattern="/**" access="ROLE_USER"/>
</security:http>

In order to use security attribute in http tag, you will need Spring Security 3.1... see http://static.springsource.org/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#new-3.1-ns

Answer 2

Try this

change

<intercept-url pattern="/login*" access="permitAll()" />

to

<intercept-url pattern="/login*" access="IS_AUTHENTICATED_ANONYMOUSLY" /> 

OR

<intercept-url pattern="/login*" access="isAnonymous()" />

As you have expression true I think you have to use isAnonymous()

See docs

intercept-url element to say that any requests for the login page should be available to anonymous users. Otherwise the request would be matched by the pattern /** and it wouldn't be possible to access the login page itself! This is a common configuration error and will result in an infinite loop in the application. Read more from here
