Static static member variables use @value injection

Use @Value annotation static type

@Component
public class MyConfig {
    @Value("${env}")
    private static String env;
 
    public static String getEnv() {
        return env;
    }
 
    public static void setEnv(String env) {
        MyConfig.env = env;
    }
}
Use the above method ,MyConfig.getEnv() Returns the null

Write it correctly

@Component
public class MyConfig {
 
    private static String env;
 
    public static String getEnv() {
        return env;
    }
 
    @Value("${env}")
    public void setEnv(String env) {
        MyConfig.env = env;
    }
}

Must be in a non static method setEnv Before using @Value annotation
