I'm doing a small project in JAVA, I'm using Spring Security for authentication, but when I try to run my code, it gives me the following Error Stack:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'adminUserConfig' defined in file [C:\Users\Matheus Castilho\Desktop\projetos\BookStoreAPI\target\classes\com\br\BookStoreAPI\config\AdminUserConfig.class]: Unsatisfied dependency expressed through constructor parameter 2: Error creating bean with name 'securityConfig': Injection of autowired dependencies failed

I have already downloaded the dependencies again, hoping that would be the case but I got the same error.
Reading this
Caused by: java.lang.IllegalArgumentException:
Could not resolve placeholder 'PUBLIC_KEY' in value "${PUBLIC_KEY}"
Generally it means that Spring can't find an environment variable called PUBLIC_KEY that is referenced to set an internal property. I suppose that in your application.properties file you have something similar to this:
jwt.public=${PUBLIC_KEY}
I suggest you to check if this PUBLIC_KEY environment variable is set, or if this is the correct name that has to be used for setting the internal properties of your beans.
