Struts中解耦与耦合

1.解耦方式获得request,session.appliction

/*Map<String,Object> reqeust=(Map<String,Object>)ActionContext.getContext().get("request");Map<String,Object> session=ActionContext.getContext().getSession();Map<String,Object> appliction=ActionContext.getContext().getApplication();*/

2.耦合方式获得request,session,appliction

String request=ServletActionContext.getRequest().getRequestURI();HttpSession session=ServletActionContext.getRequest().getSession();
