How can a new context be initiated in the system?

In Java, to initiate a new context (for example, security context, transaction, or user context), a new object is usually created or special APIs are used.

Example: creating a new security context using SecurityContextHolder in Spring Security:

import org.springframework.security.core.context.SecurityContext;
import org.springframework.security.core.context.SecurityContextHolder;

SecurityContext context = SecurityContextHolder.createEmptyContext();
// Configure the context, for example, set authentication
SecurityContextHolder.setContext(context);

For transactions in Spring, the @Transactional annotation can be used, which automatically initiates a new transactional context.

If it is about a user context, you can create a class with the necessary data and pass it along the call chain or store it in ThreadLocal.

Thus, the method of initiating a new context depends on the specific task and the libraries used.
