Class AbstractWsSecurityInterceptor

java.lang.Object
  org.springframework.ws.soap.security.AbstractWsSecurityInterceptor

All Implemented Interfaces:

ClientInterceptor, EndpointInterceptor, SoapEndpointInterceptor

Direct Known Subclasses:

Wss4jSecurityInterceptor, XwsSecurityInterceptor

public abstract class AbstractWsSecurityInterceptor
extends Object
implements SoapEndpointInterceptor, ClientInterceptor

Interceptor base class for interceptors that handle WS-Security. Can be used on the server side, registered in a endpoint mapping; or on the client side, on the web service template.

Subclasses of this base class can be configured to secure incoming and secure outgoing messages. By default, both are on.

Since:

1.0.0
