Some time ago, I wrote an article about the implementation of Spring's AOP framework, and now I'm talking about another big core concept of the IOC principle of spring.IOC: Control reversal. The official explanation is that the invocation class's

1. IntroductionDependency injection and control inversion are intended to enable the decoupling of classes from classes, to improve the scalability and maintainability of the system, and to introduce this concept through an example.2. Case studies1)

1. To read and parse an XML document: Copy Code code as follows: Saxreader reader = new Saxreader (); Document document = Reader.read (new File (FileName)); Reader's Read method is overloaded and can be read from InputStream,

Objective Through this article you can understand the list of five traversal methods and their respective performance and the implementation of foreach and iterator, deepen the understanding of ArrayList and LinkedList implementation. Let's take a

JS: var znodes=[{id:0,pid:-1,name: "Aaaa"}, {id:1,pid:0,name: "A"}, {id:11,pid:1,name: "A1"}, {id:12,pid:1,name: "A2"}, {id:13,pid:1,name: "A3"}, {id:2,pid:0,name: "B"}, {id:21,pid:2,name: "B1"}, {id:22,pid:2,name: "B2"}, {Id:23,pid:2,nam E:

The IOC (inverse of control) can be translated as "controlling reversal," but most people are accustomed to calling it "dependency injection". In spring, the IOC can configure the implementation class, parameter information, and so on in its

The Java.util package contains a series of important collection classes. This article will start with the analysis of the source, in-depth study of the internal structure of a collection class, as well as traversing the collection of iterative mode

HQL refers to hibernate query Language, which is hibernate queries the language, has a set of its own query mechanism, its query statements and SQL is very similar, in use can quickly get started. HQL provides essentially all of SQL's query

The previous article discussed in detail the HQL query in the Entity object query, and at the end of the simple introduction of SQL Native Query, HQL is the object query, so in the Query method and SQL may not be the same, in learning to use HQL
