Spring uses dependency injection to obtain simple and effective testing capabilities. Spring beans, dependencies, and beans required by services are described in the configuration file. The configuration file is generally in

IOC and DI:IOC (Inversion of control): The idea is to reverse the direction of resource acquisition. The traditional resource lookup method requires that the component initiate a request lookup resource to the container. In response, the container returns resources in a timely manner.When the IOC is applied, it is the container that proactively pushes the resources to the components it manages, and what the component does is to choose an appropriate way to receive resources.

The traditional resource lookup method requires the component to initiate a request to the container to find the resource, in response, the container returns the resource in a timely manner. When the IOC container is applied, it is the container that actively pushes the resource to the component it manages, and the component simply chooses an appropriate way to accept the resource. This

I. IOC container configuration 1. Some concepts(1)IOC container :Definition: A container that has dependencies between managing objects and managing objects.Role: The application does not need to create its own object, and the object is created and assembled by the IOC container.
