Spring Learning (i): Using Intellijidea to create a MAVEN project for the Spring IOC test IOC concept Control inversion (inversion of controls, abbreviated to IOC) is a design principle in object-oriented programming that can be used to reduce the degree of coupling between computer code. The most common way is called Dependency injection (Dependency injection, short DI). By controlling the inversion, the o

that reproduces the race condition and fixes it together. Prevent competition We're going to use a simple locking mechanism to slow down the competition. This is obviously not the ideal solution, and a better solution is to use atomic updates for data storage-but this approach is a better way to demonstrate the role of before_after in

corresponding scenario settings are as follows: Figure 4-1: Single Data Application Server scenario settings Figure 4-2: three data application server cluster scenario settings Then, this scenario is tested separately when the database is empty and the database has millions of records, after several rounds of tests, we found that the cluster performance is three to five times better than that of a single data application server. [Author's note] 1.

some other documents to provide quick guidance and an overview at a higher level. The document of the Code itself cannot answer the question about what the system is or what technology the system uses. In most cases, a simple readme. md is enough for developers to get started quickly. Such items as project description, Environment configuration, installation, build and Packaging Commands are very useful to

type of operator, these clients when querying the IP address of the domain name, the resulting IP address is the forwarding DNS server corresponding carrier type, This affects the speed at which clients that forward DNS servers access the Web site, which is not used by the same carrier as the forwarding DNS server, so pay particular attention to this issue when setting up a forwarding DNS server.This article is from the "fragrant fluttering leaves" b

The example is simple, design a program, enter three integers, determine whether the three integers as the length of the three sides can form a triangle, if you can return the type of the triangle (normal triangles, isosceles triangle or equilateral triangle)Implementation of the code (I write myself casually to do an example, the estimated code quality is poor.) ）：public class Judgetriangle{Common triangle
