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

may have different error messages in different methods. When the same error occurs in different methods, you only need to throw the same exception object. Get a more detailed error message. With exception classes, you can give an exception a more detailed, more useful error message to the user. For the user to track and debug the program. Separate the correct return result from the error message. Reduces the complexity of the program. There is no need for the

Includes: function arguments, function local variables, register values (to restore registers), function return addresses, and data for structured exception handling (when there are try...catch statements in the function, this is not discussed in this article). The data is organized in a certain order, and we call it a stack frame. A stack frame corresponds to a call to a function once. At the beginning of the function, the corresponding st

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

parameter named Msg. This method attempts to print the MSG string within square brackets. The interesting thing is to call Thread.Sleep (1000) after calling call () to print the opening parenthesis and the MSG string, which pauses the current thread for 1 seconds. The constructor for the next class, caller, references an instance of the CallMe and a string, which exist in Target and MSG, respectively. The constructor also creates a new thread that i

can continue. With multi-thread support, asynchronous calls can be used. The caller and the called can belong to two different threads. After the caller starts the called thread, wait until the other party returns the result to continue executing the subsequent code. After the called party completes the execution, notify the caller through some means: the resul

Understanding of spring control inversion and dependency Injection 1. When it comes to dependency injection (control inversion), you must first understand what dependency is. Spring calls the relationship of collaboration dependency. If component A calls the method of component B, it can be calledComponent A depends on Component B.. 2. What is dependency injection. In the traditional program design process, the caller usually creates the called inst

there are three typical scenarios: The caller (Client) broke the protocolTo be blunt is to call the method when not in accordance with the agreed specifications to pass parameters, typically such as the parameter is a non-empty set but passed in a null value. This kind of destruction protocol can also be subdivided into two categories, the caller from the interface form is not easily aware of the
