struts2攔截器中獲取session和request

在寫struts2攔截器的時候，有時會須要獲取session對象或request對象，能夠用如下方式來獲取

// 獲取session

Map<String, Object> session = invocation.getInvocationContext()

.getSession();

//獲取request

ActionContext ac = invocation.getInvocationContext();

HttpServletRequest request = (HttpServletRequest) ac

.get(ServletActionContext.HTTP_REQUEST);
