Springmvc injecting values to static variables by @value ()

Spring does not allow/does not support injecting values into static variables, such as:

@Value ("${es. Cluster_Name} ")
private static String cluster_name;

The cluster_name obtained in the method will get null

Solve
Fortunately, Spring supports set method injection, and we can inject static variables with non-static setter methods. Such as:

private static String cluster_name;

@Value ("${es. Cluster_Name} ")
public void Setclustername (String clustername) {
Cluster_Name = clustername;
}

@Value must be modified on the method, and the set method cannot have static

So we can get the value.
