Remember-me fails when two or more requests come at the same time. (without Spring Security)

由 China☆狼群 提交于 2020-04-14 07:41:12
问题 I'm trying to fix a remember-me related problem. This function was built manually, without Spring Security. Here are some details. I wanted to use Spring Security to implement remember-me functionality, but... We don't have user related data in our DB. The data is only accessible with a 3rd party API. And the API returns the data via cookies. And I don't know how to use this with Spring Security. I'm working on a legacy server without Spring Security. Maybe a bit late to implement Spring

Hibernate4 拦截器(Interceptor) 实现实体类增删改的日志记录

由 ∥☆過路亽．° 提交于 2020-04-13 11:08:34
【今日推荐】：为什么一到面试就懵逼！>>> 开发应用程序的过程中，经常会对一些比较重要的数据修改都需要写日志。在实际工作的工程中，这些数据都是存在表中的, 一个常见的做法是用触发器，在增删改的时候，用触发器将数据写入到另一张表中去，但个人不推荐这么做，原因如下: 1. 如果有多个表，得写很多触发器。 2. 触发器与数据库特性关联太紧，不同的数据库，虽然思路一样，但语法却不太一样。 对数据库表操作的日志记录，完全可以利用Hibernate的Interceptor特性来实现，也就是拦截器。下面用一个具体的例子来说明如何使用Hibernate的Interceptor。 创建一个表，用来记录日志的表 程序代码 Create TABLE `auditlog` ( `AUDIT_LOG_ID` BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT, `ACTION` VARCHAR(100) NOT NULL, `DETAIL` text NOT NULL, `CreateD_DATE` DATE NOT NULL, `ENTITY_ID` BIGINT(20) UNSIGNED NOT NULL, `ENTITY_NAME` VARCHAR(255) NOT NULL, PRIMARY KEY (`AUDIT_LOG_ID`) ) ENGINE=InnoDB

SpringBoot: Interceptor to read particular field from request and set it in the response

问题 All requests and responses handled by our Spring Rest Controller has a Common section which has certain values: { "common": { "requestId": "foo-bar-123", "otherKey1": "value1", "otherKey2": "value2", "otherKey3": "value3" }, ... } Currently all my controller functions are reading the common and copying it into the response manually. I would like to move it into an interceptor of some sort. I tried to do this using ControllerAdvice and ThreadLocal : @ControllerAdvice public class

Angular 5 Interceptor doesn't intercept requests made from a library

由 左心房为你撑大大i 提交于 2020-04-10 04:12:26
问题 I have a working interceptor in Angular 5. It's registered in App.module's providers and correctly intercepts all requests made from the application. The problem is that it doesn't intercept the requests made from the libraries used by the app. I'm using an open source library (NGX-Jsonapi), and need the interceptor to provide a token in every request that the library makes to the back-end. Someone faced the same issue? EDIT: the library uses HttpClient. 回答1: With version 4.3, angular added a

Override/Intercept XMLHttpRequest response in all browsers

由 大城市里の小女人 提交于 2020-03-25 19:15:14
问题 What do I want to achieve ? I want to intercept the XMLHttpRequest and modify the response for some particular requests. (For ex. decrypt content and assign it to back response) What I have done so far ? Below code intercepts the request and modifies the response. It works in all browsers (Chrome, Firefox, Opera, Edge) except IE 11. const dummySend = XMLHttpRequest.prototype.send; XMLHttpRequest.prototype.send = function () { const _onreadystatechange = this.onreadystatechange; this

Interceptors Or Filters

由 回眸只為那壹抹淺笑 提交于 2020-03-18 05:53:26
问题 I am working on an Spring Application in which I want to do some security checks like MD5 checking of files, DB checking, Application version check etc. I have read about Interceptors and Filters but still a bit confuse about which one is good to use. Whatever documents I have read, it is specified that filters and interceptors both can be used for Logging and auditing so which one is good for this scenario. Also all this security checks (MD5 checking of files, DB checking, Application

Springboot项目的接口防刷（实例）

由 一笑奈何 提交于 2020-03-13 14:39:14
技术要点：springboot的基本知识，redis基本操作， 首先是写一个注解类： import java . lang . annotation . Retention ; import java . lang . annotation . Target ; import static java . lang . annotation . ElementType . METHOD ; import static java . lang . annotation . RetentionPolicy . RUNTIME ; /** * @author yhq * @date 2018/9/10 15:52 */ @Retention ( RUNTIME ) @Target ( METHOD ) public @interface AccessLimit { int seconds ( ) ; int maxCount ( ) ; boolean needLogin ( ) default true ; } 接着就是在Interceptor拦截器中实现： import com . alibaba . fastjson . JSON ; import com . example . demo . action . AccessLimit ; import com . example .

JAX-RS writer interceptor works for every response even with NameBinding

由 假如想象 提交于 2020-03-03 13:00:14
问题 I need to intercept a response from the server that was generated for a specific API call and change it. I used the JAX-RS 'WriterInterceptor' for this and I have created a NameBinding as well. But the server is intercepting every response out from the server. What am I doing wrong here? Shown below is the code I have tried. Why is the name binding does not work? (I have verified that when calling other API resources the particular method that I have use name binding is not called.) Name

spring context源码解析之@Async

一、背景 本文转自“天河聊技术”微信公众号 大家项目中用到异步、多线程的场景很多，使用最多的场景还是主动对象模式，就是主线程开启一个线程池去任务分发，任务执行完成之后，关闭线程池，但是有的场景则需要部分代码异步执行的效果，简单的说就是有一个可以复用的线程池可以复用，直接new Thread当然也可以，不推荐，没有线程池的可靠性好，如果这个时候再创建一个线程池用完再关闭代码是不是有点重，维护性也不好，@Async这个注解就是为了解决这个问题，只需要在bean的方法上加上这和注解即可，就可以实现异步。 二、正文 先简单介绍下怎么使用 1、先在程序上加上@EnableAsync这个注解，可以指定执行器，如果不指定就从beanFactory中获取taskExecutor这个执行器 @Async(value = "executor") public void test(){ 2、如果想自定义执行器，实现这个接口org.springframework.scheduling.annotation.AsyncConfigurer或者继承org.springframework.scheduling.annotation.AsyncConfigurerSupport这个类 public class AsyncExecutor implements AsyncConfigurer { @Override
