Struts2中怎么利用interceptor實現(xiàn)權(quán)限管理,相信很多沒有經(jīng)驗的人對此束手無策,為此本文總結(jié)了問題出現(xiàn)的原因和解決方法,通過這篇文章希望你能解決這個問題。
Xml代碼
<interceptors> <interceptor name="authentication" class="com.tiantian.tiantian.web.interceptor.AuthenticationInterceptor"></interceptor> <interceptor-stack name="myInterceptorStack"> <interceptor-ref name="authentication"></interceptor-ref> <interceptor-ref name="defaultStack"></interceptor-ref> </interceptor-stack> </interceptors> <default-interceptor-ref name="myInterceptorStack"/>
Java代碼
@Override public String intercept(ActionInvocation invoke) throws Exception { // TODO Auto-generated method stub HttpSession session = ServletActionContext.getRequest().getSession(); ApplicationContext context = Util.getContext(ServletActionContext.getServletContext()); PriorityService priorityService = context.getBean(PriorityService.class); String actionName = invoke.getProxy().getActionName(); String methodName = invoke.getProxy().getMethod(); if ("execute".equals(methodName)) methodName = "index"; int index = actionName.indexOf("/"); String name = actionName.substring(0, index); Priority priority = priorityService.find(name, methodName); Object obj = session.getAttribute("user"); if (obj != null) { User currentUser = (User) obj; ModuleService moduleService = context.getBean(ModuleService.class); Module module = moduleService.findByUrl(name+"/"+methodName); if (module != null) { SystemDiaryService sdService = context.getBean(SystemDiaryService.class); SystemDiary diary = new SystemDiary(); diary.setOperator(currentUser); diary.setOperateModule(module.getName()); sdService.add(diary); } if (priority != null) { boolean hasPermission = currentUser.hasPermission(priority); if (!hasPermission) { return "forbidden"; } } } // System.out.println("name = "+name + "**actionName = "+actionName+"*methodName = "+methodName); String result = invoke.invoke(); return result; }
