In spring, there are five types of beans in scope: The default is singleton mode,SingletonPrototypeRequestSessionGlobal sessionWhen configuring scopes, using the Scope property, the XML file is configured as followsTo view the official spring documentation, explain the following:1, Singleton If a bean is configured as Singelton, it indicates that the bean has only one instance in the spring IOC container, t

It can be said that each mybatis is centered on a sqlsessionfactory instance. Sqlsessionfactory instances can be built by Sqlsessionfactorybuilder. One is that the sqlsessionfactory can be built in the form of an XML configuration file, and the second is built through the Java API. However, there is a configuration through which all the configurations are implemented through the config instance.This article is intended to implement the scope and life

Scope in a functionThe so-called function scope, that is, all the variables that belong to this function can be used and reused throughout the scope of the function.1 function foo (a) {2 var b=a;3 function Bar (c) {4 var c=b*2;5 Console.log (c); 6 }7 Bar (); }9 foo (3);1 function foo (a) {2

Scope rules that are common in development languages have block-level scopes and lexical scopesThe scope in which the scope can function is defined by its name, which is the area that defines a variable.Block-level scope is to use a block structure to partition the variable access area block that {} represents the lang

I believe that many beginners in JavaScript and the execution environment and scope chain can not be very good understanding, here, I will follow their own understanding to share with you. In general, we divide the execution environment into global execution environment and local execution environment, in which local execution environment can be called function execution environment. So what exactly makes the execution environment? In layman's parlan

var i = 2,x = 5;var fn = function (x) {x + = 3;return function (y) {Console.log (x + +) + y + (--);}};var f = fn (1);F (2);FN (3) (4);F (5);Answer: F (2) = 7; FN (3) (4) = 10; F (5) =>9;Problem Solving Ideas:1. var f = fn (1); equivalent to opening a heap of memory (private scope), parameter assignment. Top-down execution, x assignment is 4;2. F (2) performs a return function (y) parameter assignment, function (y) opens up a heap of memory, X does no

() as a class function, that is, as a function of a class itself, instead of any object of this class. There are class functions, but there are no classes of variables. In fact, there is no object at all when the function is called. Thus a function of a class can use no object (but local or global variables can be used), and you can not use $this variable at all. In the example above, class B redefined the function example (). The original defined function example () in Class A is masked and no

Any set of statements in a pair of curly braces belongs to a block, and all variables defined in it are not visible outside the code block, which we call a block-level scope.Scope is always a priority in any programming language because it controls the visibility and life cycle of variables and parameters. First we understand two concepts: block-level scope and function scope.What is a block-level scope?Any

In Oracle, the scope = both and scope = spfile options are described. scopespfile In Oracle, there is a thing called spfile, that is, the dynamic parameter file, which sets various Oracle parameters. The so-called dynamics mean that you can change database parameters without shutting down the database and record them in spfile. There are four scope options when

Scope is always the most important in any programming language, because it controls the visibility and lifecycle of variables and parameters. Here, we first understand two concepts: block-level scope and function scope. What is a block-level scope? The set of statements in any pair of curly braces ({and}) belongs to

Local variables are defined throughout the function body, which means that global variabl
