Example 56 with Interceptor

use of com.opensymphony.xwork2.interceptor.Interceptor in project struts by apache.

the class ActionAutowiringInterceptor method intercept.

/**
 * <p>
 * Looks for the <code>ApplicationContext</code> under the attribute that the Spring listener sets in
 * the servlet context.  The configuration is done the first time here instead of in init() since the
 * <code>ActionContext</code> is not available during <code>Interceptor</code> initialization.
 * </p>
 *
 * <p>
 * Autowires the action to Spring beans and places the <code>ApplicationContext</code>
 * on the <code>ActionContext</code>
 * </p>
 *
 * <p>
 * TODO: Should this check to see if the <code>SpringObjectFactory</code> has already been configured instead of instantiating a new one?  Or is there a good reason for the interceptor to have it's own factory?
 * </p>
 *
 * @param invocation the action invocation
 * @throws Exception in case of any errors
