30-year-old Cao, 20-year-old body, still in the ability to allow control within the range of 22 o'clock to sleep, 5 o'clock to get up and exercise, to learn, in addition to overtime or late at night, like today, once again wrote the X million people wrote the Spring Ioc summary blog.First, the IOC control reversal of the detailed:1). Call dependencies between objects in traditional non-spring management:We all know that a broken frame of the book says one of spring's core ioc-control

(1) Why use control inversion and dependency injection The caller does not have to care about the callee's implementation, and it does not require the caller to create the callee's instance personally, which is given to the framework to complete. This design idea is control inversion (inversion of control, IoC), and it has another name that is dependency inject

Individual study notes, from Acode.1. TerminologyControl inversion/Reverse control, English full name "inversion of Control", referred to as IOC.Dependency Injection, English full name "Dependency injection", referred to as DI.It is said that Martin Fowler after a deep exploration of the principle of inversion of control, a new name called "Dependency Injection"

The dependency inversion principle (Dependency inversion Principle) provides us with a way to reduce the coupling between modules, and the dependency injection (Dependency injection) is a concrete implementation method.Dependency Inversion principle:The previous article on software design principles has already mentioned the "dependency

Dependency Injection and control inversion Dependency Injection When I first touched the word, I was somewhat confused, so far I am also confused, so today we will explore the laravel in the dependency injection (Dependency injection), to understand it well. control reversal The first impression is a good abstruse noun ... Looks like a reverse control? Don't understand? Then straighten it out! Starting point What is dependency I can not live with

The relationship between one component and another can be established in three ways: event, dependency inversion, and Bridge. Now we only consider one-way dependency, that is, information providers and information consumers. An event is a loosely coupled information publishing method. The event publisher (information provider) does not need to care about any information of the event subscriber (that is, information consumer, however, the event prefere

Column-and-column inversion is a common technique in sqlserver. When using an application system, you often need to do some statistical functions to avoid using the column-and-column inversion technique, I made a small summary: the first type: Use case in sqlserver2000 to invert the rows and columns. createtableRowCellConvertTest (gradevarchar (50), sex Column-and-column

BackgroundSpringmvc, who has recently been exposed to a period of time, is impressed with its inversion of control (IoC) and Dependency Injection (DI), and has since been thinking about how to achieve these two features with OC language. The Java language comes with an annotation feature that brings great convenience to IOC and DI, and it requires a little bit of skill to implement these two functions better on OC.Control

Translated from: https://www.cnblogs.com/xxzhuang/p/5948902.htmlWe look back on the history of the computer, from the first computer to occupy an area of 170 square meters, weighing 30 tons, to today's personal notebooks, things more lightweight function is more rich, this is a trend in the development of things, in the technical field is also the same, Enterprise JavaBean, EJB, was very successful at the time of its creation, but as the years began to chase more convenient and lightweight techn

The basic architecture of a program should be an abstraction layer with stable dependencies.The concrete implementation of the program relies on a stable abstraction layer.This will ensure the stability and scalability of the program.http://blog.csdn.net/coolingcoding/article/details/8043265Dependent on abstraction: the recommendation does not depend on a specific class, that is, all dependencies in a program should terminate in an abstract class or interface.Hierarchical: All well-structured ob

Ioc--inversion of Control inversionDi--dependency Injection Dependency InjectionTo understand the above two concepts, it is necessary to clarify the following questions: Who are the participants? Dependence: Who depends on who? Why do I need to rely? Inject: Who injects into who? What exactly is injected? Control reversal: Who Controls who? Control what? Why is it called inversion (ther

Dependency Injection is a design pattern in PHP programming and is designed to reduce coupling and improve maintainability.Problem phenomenon: We often encounter a class in the programming process to instantiate another class, this class is instantiated another class, this layer of package form, often let us modify the code at the time, modified once, related to the upper layer will also be modified, if the hierarchical relationship is more complex, this modification is catastrophic. Workaround:

The PHP bitwise inversion problem now has a string of numbers, $ str = 1300022332121 requires bitwise inversion. how can we get this bitwise inversion, which is opposite to the bitwise inversion of other programs, is there a difference, because I want to pass it to a program written in C ++. ask everyone to teach, PHPc

AUTOFAC is a. NET platform issued a good performance of the IOC framework, using it can achieve dependency injection and control inversion, so that the coupling between their software modules greatly reduced, so that software expansion, maintenance easier. Control inversion (inversion of the English abbreviation for IOC) is an important object-oriented programmin

Author informationText Description Inversion: The line of matrix A is replaced by the corresponding column , and the resulting new matrix is called a transpose matrix, which is recorded as at or a. The first column of the matrix is usually the first row of the transpose matrix, and the first row is the first column of the transpose matrix. So, in the order storage structure of ternary group that has been store
