Action context: ActionContext

Through ActionContext, you can obtain:

ActionContext ctx = ActionContext.getContext (); / / Returns a Map of the ServletContext when in a servlet environment or a generic application level Map otherwise. Map smap = ctx.getApplication (); / / context Map s2map of struts2 = ctx.getContextMap (); / / get native HttpServletRequest HttpServletRequest request = (HttpServletRequest) ctx.get (StrutsStatics.HTTP_REQUEST); / / get request parameter Map pmap = ctx.getParameters (); / / Session Map session = ctx.getSession ()

If it is an ioc application implemented through spring, you can get the context of spring:

WebApplicationContext context = (WebApplicationContext) smap.get (WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE); DataSource dateSource = (DataSource) context.getBean ("dataSource"); the above is how to get some parameters of struts2.
