Home > FAQs > How can we access request parameters passed into an Action |
You can obtain the request parameters by asking the ActionContext or implementing ParameterAware. Implementing ParameterAware is preferred.
The request parameters are available on the ActionContext instance, which is made available via ThreadLocal.
Map parameters = ActionContext.getContext().getParameters();
Preferred
servlet-config
Interceptor is included in the Action's stack.servlet-config
.setParameters
method. You may wish to include a companion getParameters
method.getParameters
to obtain an object representing the request parameters.
When the servlet-config
Interceptor sees that an Action implements ParameterAware, it passes a Map of the request parameters to the Action's setParameters
method.
