自己写一个interceptor,该interceptor继承interceptor接口,实现其中的intercept方法;然后在struts.xml
中进行配置,并把该interceptor置于默认的interceptor中,注意,这里在设置默认的intercept的时候
一定要加上原来的intercept,否则原来的就不可以用了,就不能用struts2了,具体来说是这样:
<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"/>
@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();//获取action的名称
String methodName = invoke.getProxy().getMethod();//获取执行的方法
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);
}
使用struts2时定义一个servlet过滤器 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;
}
