ThreadLocal is a class in Java that provides thread-local variables. It means that each thread accessing a ThreadLocal object has its own separate copy of the variable. ThreadLocal is commonly used in multi-threaded applications where different threads may need to access the same object concurrently, but each thread needs its own copy of the object to work with.
SSM (Spring State Machine) is a framework that enables developers to create and manage state machines in their applications. A state machine is a model that describes the behavior of a system based on a set of states and transitions. SSM provides a way to define state machines using a fluent API and configure transitions between states using events.
ThreadLocal can be used with SSM to maintain the state of a state machine for each thread separately. This is useful in scenarios where multiple threads are working on the same state machine concurrently, and each thread needs to maintain its own state. By using ThreadLocal, each thread can have its own copy of the state machine, and changes made by one thread will not affect the state of the state machine in other threads.
