stateless microservices

Preface HTTP protocol A total of five features, 1, support client/server mode, 2, simple and fast, 3, flexible, 4, no connection, 5, stateless. None of the states is one of the main features. Therefore, it is often said that HTTP is a stateless protocol. The so-called stateless means that the protocol has no memory capacity for transactional processing. When the

The rest architecture design is a very hot concept that has become the de facto standard to be followed when building Web services. A very important rule in rest constraints is "stateless", but "stateless" is a very abstract concept, and it is difficult for a person who has just come into contact to have a deep understanding of the image. Today, read an article on the internet, for the "

HTTP is a stateless protocol, with two consecutive requests for the same session that are not known to each other, and they are parsed by the newly instantiated environment, which does not save any information about the session, except that the application itself may have all the information stored in the global object.Own understanding, In asp: Each time the page is submitted to the server does not have any relationship, each time the information rec

Static stateless 2-way NAT on Linux with iptables application instance, statelessiptablesIn the past few days, I completed a static stateless 2-way NAT and wrote several articles, but focused on theoretical analysis. This article shows an application instance. Before presenting an instance, let's talk about the difference between a static stateless 2-way NAT and

There is a lot of information on how to configure Nat on Linux, which is overwhelming! This article has nothing to do with this. This article provides a way outside of iptables.Iptables No! Why Because the NAT configured by Iptables is stateful, its implementation relies on a module called Conntrack, what is Conntrack? Oh,no! This is my specialty, but I don't want to say it in this article, people who know me know that I can pull this topic for 12 hours ... They're not even finished. You may not

HTTP is a stateless protocol. Two consecutive requests in the same session do not know each other. They are parsed by the latest instantiated environment, except for all information that the application may have stored in a global object, the environment does not save any session-related information. The status of the Protocol indicates the ability to "remember" The transfer information during the next transmission. HTTP does not maintain the informat

Load balancing is an essential name for any high-availability, high-load system. In a large-scale distributed computing system, a service in a single case, it is difficult to deal with a variety of unexpected situations. Therefore, load balancing is a solution that allows the system to distribute traffic in the event of a performance bottleneck or in some of these states. In the Springcloud system, many of Netflix's best products have been added, one of which is the Ribbon for server-side load b

invoke the microservices directly; There is also a call relationship inside a microservices service. Design concept Modularity is the basis of Non-modular, not much micro-services, such as the above user micro-services, product microservices, address micro services, etc., need to be modular, in order to better implement the development, yo

Do not get webservicecontext property from stateless bean context, it shoshould already have been injected This is mainly because of the stateless bean implementation class. After careful viewing, I found that I added @ webmethod before every method of the implementation class (specifying the method exposed to the outside world), so I can remove it. 13:41:39, 168 warn [statelessbeancontext] EJBTHRE

In recent years, the development of the Java industry has grown exponentially. As an enterprise application developer, architecture architect, or technical manager, you can choose from many vendors, best practices, specifications, and component types for your Java technology implementation. The purpose of the Java EE Explorer series is to help you find a way to assist you in selecting the right technology for any given situation. In this article, the 1th part, we will explore the

NHibernate 3.0 Cookbook The third chapter, Using stateless sessions translation.When dealing with large amounts of data, you may often use the more "bottom-up" API to improve performance, and many of the advanced features are turned off in this process. In NHibernate, the stateless session is the high performance, underlying API.This article, we will use a stateless
