About springboot delayed loading

Lazy loading or delayed loading means that when the spring container starts, it does not load all the bean into the spring container, but instantiates the object into the container when it is needed.

Advantages:

Shorten startup time

Disadvantages:

If a configuration error occurs, it will not be found when the system starts up, it needs to be strictly tested, and it is necessary to ensure that the heap space of JVM can meet all bean.

Lazy loading is divided into global lazy loading and local lazy loading. Global lazy loading is realized by configuration, and local lazy loading is achieved by adding @ Lazy annotation to the class.
