1. IntroductionIn the previous article, I introduced you to how Spring MVC handles HTTP requests. When Spring MVC can provide services externally, it indicates that it is already in a ready state. Again, Spring MVC requires a series of initialization operations. The so-called soldiers do not move, fodder first. These operations include creating containers, loading various components used in Dispatcherservlet, and so on. This article will discuss with you the

equals () and hashcode ();Equals (): is only responsible for comparing the values of two objects for equality;Hashcode (): Determines whether two objects point to the same object (reference) and returns a hash code value; Map Interface:Key cannot be duplicated;Implementation class: HashMap, TreeMap, Linkedhashmap;Common methods:Put (Object K,object v);Get (Object key);//Returns the value mapped by keyContainsKey (Object o);//Determines whether the given element o is contained in the

, we can use singleton mode, only one instance is running or multiple instances can be run. Do you have this configuration in the IOC container? Of course, that is the scope scope of the bean. Singleton the default value, each call to Getbean () is identical to the object obtained in the IOC container. That is, a single case. In the case of prototype, it is not the same for each call to Getbean () to get ob

automatically expand capacity.(4) if you want to do a lot of random access, use ArrayList( with the characteristics of the array ), if you want to frequently insert or delete elements from the middle of the table, you should use LinkedList (features with linked list)(5) the behavior of various queue (queue) and stack, supported by LinkedList .(6) Map is a design that associates an object, not a number, with an object. HashMap designed for quick acc

Laravel framework of dependency injection is really powerful, and through the container to implement dependency injection can have selective loading of the required services, reduce the overhead of the initialization framework, below is a post I saw on the Internet, written well to share with you, From the beginning of the traditional class design database connection to the

Brief introductionThe Linux container is a lightweight "virtualization" approach for running multiple virtual appliances (containers) concurrently on a single control host. Another term that can be used to describe the operations performed by the Linux container is "containerized."Linux containers provide OS-level virtualization in which the kernel controls the quarantined containers. The

become the first choice of many companies containerized platform. In the process of landing, there is always more or less the need to expand the k8s to better meet the needs of enterprises. K8s Native provides a number of extension mechanisms that can be extended without intrusion, such as CRD, API aggregation, and so on. This share mainly introduces the exploration and practice of NetEase cloud container service platform in k8s extensibility, hoping

Responsibility chain mode: The chain of responsibility model can be used in such a scenario, when a request comes over, it is necessary to do a series of processing of this request, the use of the chain of responsibility model can make each processing components, reduce coupling. can also be used when a request comes in, you need to find the right processing method. When a process is not suitable for this request, it is passed to the next processing method, which attempts to process the request

Containers, iterators, and container adaptersThe so-called container, which is the most frequently used data structures, is implemented with class templates to accommodate specific types of objects. Depending on the characteristics of the data in the container, the container can be divided into sequential (sequence) an

type of pointer passed to deleteobject: Operator () to eliminate this error (also reduce the number of times that the deleteobject user needs to strike keys ). All we need to do is move templated from deleteobject to its operator (): Struct deleteobject {// Delete the template and base class template The compiler knows the type of the pointer passed to deleteobject: Operator (), so we can let it automatically instantiate an operator () through the pointer type (). This kind of deduction declin

[4] The Symbian container Symbian did not embrace STL at the beginning of its design. This requires that it re-create some wheels, and the container is one of them. The designers of the carray series container Symbian like the complicated inheritance structure and Paul Vientiane class. The carray series

ChatWhether it is to do the development of the Java EE or do J2SE development, spring is a broadsword. In today's popular SSH three framework, spring is the most irreplaceable, if not hibernate and struts, I think it is irrelevant, but not without spring, some people may say spring is useless ah? The direct new object has nothing to do with an IOC so troublesome, and difficult to understand, so much more configuration, write code did not feel the value of its existence, once I have always though

storage, retrieval, and integration of data. Therefore, it is necessary to split these services into their own containers through design and deployment. If an application can be split into more distributed components, the more choices the application extends. However, the more distributed components, the higher the complexity of management. Step 2: Select an underlying image When performing an application migration, try to avoid the practice of top

Docker Container Learning grooming--web Management tools Dockerui Deployment RecordsDocker provides a platform to package, distribute, share, and run applications as containers, and it has saved thousands of system administrators and developers by saving hours of work. Docker does not care what operating system is running on the host, it does not have the limitations of developing a language, framework, or packaging system, and can be run at any time,

In the Docker section, you see how to run a service in Docker container through a network port connection. But port connectivity is just a way to interact with services or applications that run in Docker container. In this section, we will simply reply to the way the network port connection is established, and then introduce another way of accessing: container li
