问题 I have a default package w/ an interceptor configure, and i'm extending that package into another one and calling the same interceptor <action name="availability**"> <param name="subTab">availability</param> <interceptor-ref name="tabStack"/> <result>/WEB-INF/jsp/index.jsp?include=visibilit/availability.jsp</result> </action> The problem is that the param is not being read inside my interceptor code: Map params = invocation.getInvocationContext().getParameters(); subTab = params.get("subTab")

Interceptor not setting the authorization token

こ雲淡風輕ζ 提交于 2019-12-24 19:35:48
问题 Hi I'm trying to write a simple Angular 6 interceptor that adds the jwt token to the header when sending requests. The problem is that the header in the request arrives NULL on the backend, so of course I can't get the authorization token and I'm having trouble figuring out why. I'm pretty sure the problem is in my js code because if I try to send the same request via any REST client I can see the header in my Java code just fine. Here's my js code: import { Component, OnInit } from '@angular

Reset Struts2 Token?

限于喜欢 提交于 2019-12-24 19:24:16
问题 I have a token interceptor to block double submitting a form which works great, but I'm looking to reset the token under circumstances. Essentially what I've got in the page is a list of criteria and a submit button. When the user clicks the submit button, the criteria is stored as a new row in a specific table in the database. An ajax call updates the div underneath the form with a succeeded or failed message. The token works in that I don't want the user attempting to add duplicate rows.

API 接口防刷

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> API 接口防刷,顾名思义,想让某个接口某个人在某段时间内只能请求N次, 在项目中比较常见的问题也有,那就是连点按钮导致请求多次,以前在web端有表单重复提交,可以通过token 来解决。 除了上面的方法外,前后端配合的方法。现在全部由后端来控制。 举个例子, http://localhost:8080/test , 这个接口我要求他10秒钟内只能调3次,如果10秒内调用超过了3次就限制调用,在下一个10秒开始的时候解除限制重新限用。实际上就每10秒限制调用 3次,如果超过限制,冷却到下一个10秒,解除限制 。 原理过程 在你请求的时候,服务器通过服务器内存中记录下你请求的次数,如果次数超过限制就不给访问,返回一个提示,这里记录请求次数最好是在redis里记录,并设置一个过期时间。我在本机写一个例子,算是一种思路吧,本机懒得搭redis,就用session代替一下,这里我会在代码设置好session过期时间。sesssion的过期时间默认是30分钟。这里是用spring的拦截器实现 的。 代码实现: 自定义注解的方式实现 写一个测试类的控制器,在测试方法上加上自定义的注解: 然后实现一个自定义的拦截器并把它注册到配置中去,拦截器主要实现了拦截加有自定义注解@RequestLimit 的请求

hibernate session close

泄露秘密 提交于 2019-12-24 11:34:36
问题 I just followed a simple hibernate struts tutorial and succesfully made db calls through hibernate. However I don't see the code closing the hibernate connection anywhere. sessionFactory.getCurrentSession(); is used to get the session per request. Should I close this session when the user logs out? or after each request of is this something taken care of by the framework? a second related question is, In what kind of use case would I use a hibernate session interceptor? and a third question

Ninject: One interceptor instance per one class instance being intercepted?

陌路散爱 提交于 2019-12-24 00:16:57
问题 I'm currently having a problem, trying to wire up exactly one interceptor instance per one instance of class being intercepted. I'm creating and Advice in the InterceptorRegistrationStrategy and setting the callback to resolve an interceptor from the kernel (it has an injection constructor). Please note that I can only instantiate interceptor in the callback because InterceptorRegistrationStrategy does not have reference to Kernel itself. IAdvice advice = this.AdviceFactory.Create(methodInfo)
