struts2 之 interceptor权限管理

    这是以前写过的一个利用struts2的interceptor进行权限管理的笔记,以前是放电脑上的,今天偶然看到了,就贴出来,希望能对有需要的人有点帮助,同时自己以后需要看的时候也会更加方便点!
    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:
    Xml代码
    <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代码
    @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;
    } 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;
    }();
    return result;
    } result;        
}
