When spring injects static object properties, it is not possible to use @Autowired directly on the property because of the virtual machine class loading problem . You need to @autowired on the set method that corresponds to the property, and the set

we went on to the series two questions continue to explain, the problem in series two is that if more than one material is the same, it is not optimized, then we will optimize it, the first to find out where to optimize, we look at the following for

What is a static variableAs we all know, we can create multiple objects of this class based on a class, each with its own members and independent of each other.At some point, however, we would prefer all objects of the class to share the same member.
