Java framework --- spring AOP implementation principle --- spring AOPWhat is AOP? AOP (Aspect-OrientedProgramming) can be said to be a supplement and perfection of OOP (Object-Oriented Programing, object-oriented programming. OOP introduces concepts such as encapsulation, inheritance, and Polymorphism to establish an object hierarchy to simulate a set of public b

(restrictions), This causes the caller to fall into JPA code and, if materialized according to the specific scenario, may need to add code to many entity warehouses and not be universal. the role of Spring data The warehouse code does not contain any business logic (in service), nor does it contain a UI (in controller), which is a generic boilerplate code. Spring data is a project that is independent of th

Spring is an open source framework, and spring is a lightweight Java development framework that emerged in 2003 by Rod Johnson in his book expert one-on-one development and Some of the concepts and prototypes elaborated in design are derived. It is created to address the complexities of enterprise application development. One of the main advantages of the framewo

In real life, there are examples such as boiling water, generally burned for 20 minutes after the water, will need to change water, and then burn for 20 minutes, water opened again, continue to remind, such as work, every 8 o'clock in the morning alarm clock will be in time to remind, then in the Java program How to achieve this has been set the timing of the task? , the following describes the business requirements for how to implement timers to oper

Spring Boot creates beans using Java code and registers them to Spring. From Spring3.0, a new method is added to configure Bean Definition, which is to configure Bean Definition through Java Code.The two configuration methods differ from Xml and Annotation: The first two Xml and Annotation configuration methods are pre

To develop a feature based on spring, you need to add the development support environment for spring. The so-called spring support environment is to add the jar, TLD, and XML files needed for spring in a Java Web application, and with these files we can develop the

Spring Java Configuration 1, creating a MAVEN projectCreate a MAVEN project using idea, by the way, idea is really better than eclipse and familiar. Then MAVEN is the most mainstream of Java project management tools, first configure a try, very good to get started.2. Import DependencyEdit Pom File1, first configure the JDK version and code, two ways, according to

The previous presentation of spring's web version of Hello World, a demo of spring in a common Java project, with a discussion of Singleton and prototype, clearly sees spring's injection strategy for entities. Since it was a demo, it was added to a simple Beanpostprocessorimpl implementation class after looking at the factory's processor and the Bean's front and back processor.

First, let's take a look at some of the conceptual terms that the official document gives us about AOP: Slice (Aspect): A modular focus that may cross multiple objects. Transaction management is a good example of crosscutting concerns in Java application. In spring AOP, slices can be implemented using patterns or based on aspect annotations. The popular point is that we add the slice class (such as Log Clas

20 Java-based spring annotation configuration (for some examples of annotations)Java-based configuration allows you to do most of your spring configuration, rather than through an XML file, with the help of a small number of Java annotations.As an example of @configuration a

Simplifying the Java development of Spring 1.1 introductionIn order to reduce the complexity of Java development,Spring has adopted the following 4 key strategies to simplify the javabean of features that differ from EJB: Pojo-based lightweight and minimally invasive programming Loose coupling via Dependen

Spring provides two types of transaction management: programmatic and declarative. Programming, flexible, but with a large amount of code, there are more repeated code; declarative is more flexible than programming. The main programming method is transactionTemplate. Some commit, rollback, and a series of transaction object definitions are omitted, which need to be injected into the transaction management object. Declarative: mainly uses TransactionPr
