Introduction to Active Object Mode
Active Object mode is an asynchronous programming pattern. It improves concurrency by decoupling the invocation of the method from the execution of the method. In the concept of a task, the core of the Active objec

The function set (X,y) is used to specify the value of a vector, and the x,y value of the caller itself is affected, and the method itself returns to the caller itself, which is common, as the following no longer explains. It is no longer possible to refer to the source code with functions that can be expressed clearly by text.

languages automatically prevent this error. For pointers, the programmer must verify that the allocation is handled correctly. Local Storage
Local variables are the most common variable.
Variables are called "local", meaning that their lifecycle and functions are tied together. Born with a function, dead and dead.
The only difference between a parameter and a local variable is that the parameter is passed from the caller and the local variable starts
Spring can effectively organize objects at various layers of J2EE applications. Whether it is the action object of the control layer, the service object of the business layer, or the DaO object of the persistence layer, it can be organically coordinated and run under the management of spring. Spring organizes objects at different layers in a loosely coupled manner. Action objects do not need to care about the specific implementation of service objects, and service objects do not need to care abo

How can I limit the frequency of API calls by interface callers? Problem: Add a limit to an externally exposed interface: the number of calls by the caller within one minute cannot exceed 100. If the number of calls exceeds 100, the caller will be directly returned with the message of failure. To give the caller a SECRET, each time the
