Method Detail

init

public void init(javax.servlet.FilterConfig arg0)

Not used (we rely on IoC container lifecycle services instead)

Specified by:

init in interface javax.servlet.Filter

Parameters:

arg0 - ignored

destroy

public void destroy()

Not used (we rely on IoC container lifecycle services instead)

Specified by:

destroy in interface javax.servlet.Filter

doFilter

public void doFilter(javax.servlet.ServletRequest request,
                     javax.servlet.ServletResponse response,
                     javax.servlet.FilterChain chain)
              throws java.io.IOException,
                     javax.servlet.ServletException

Method that is actually called by the filter chain. Simply delegates to the invoke(FilterInvocation) method.

Specified by:

doFilter in interface javax.servlet.Filter

Parameters:

request - the servlet request

response - the servlet response

chain - the filter chain

Throws:

java.io.IOException - if the filter chain fails

javax.servlet.ServletException - if the filter chain fails

getSecurityMetadataSource

public FilterInvocationSecurityMetadataSource getSecurityMetadataSource()

obtainSecurityMetadataSource

public SecurityMetadataSource obtainSecurityMetadataSource()

Specified by:

obtainSecurityMetadataSource in class AbstractSecurityInterceptor

setSecurityMetadataSource

public void setSecurityMetadataSource(FilterInvocationSecurityMetadataSource newSource)

getSecureObjectClass

public java.lang.Class<?> getSecureObjectClass()

Description copied from class: AbstractSecurityInterceptor

Indicates the type of secure objects the subclass will be presenting to the abstract parent for processing. This is used to ensure collaborators wired to the AbstractSecurityInterceptor all support the indicated secure object class.

Specified by:

getSecureObjectClass in class AbstractSecurityInterceptor

Returns:

the type of secure object the subclass provides services for

invoke

public void invoke(FilterInvocation filterInvocation)
            throws java.io.IOException,
                   javax.servlet.ServletException

Throws:

java.io.IOException

javax.servlet.ServletException

isObserveOncePerRequest

public boolean isObserveOncePerRequest()

Indicates whether once-per-request handling will be observed. By default this is true, meaning the FilterSecurityInterceptor will only execute once-per-request. Sometimes users may wish it to execute more than once per request, such as when JSP forwards are being used and filter security is desired on each included fragment of the HTTP request.

Returns:

true (the default) if once-per-request is honoured, otherwise false if FilterSecurityInterceptor will enforce authorizations for each and every fragment of the HTTP request.

setObserveOncePerRequest

public void setObserveOncePerRequest(boolean observeOncePerRequest)
