However, regardless

functionality, and facets provide another alternative to inheritance and delegation, and are clearer and more concise in many scenarios.While we are still defining common functionality in one place while using face-oriented programming, we can provide a declarative way to define how this function is applied in any way, without modifying the affected classes.Crosscutting concerns can be modularized into special classes, which are called facets.Section

to elaborate. Weaving (weaving) the process of applying facets to a target object to create a new proxy object. There are three ways that Spring uses the runtime, and why it is run, in the previous article "a discussion of spring AOP Development Ramble about the use of AOP and AspectJ" in the second label mentioned. Target Object – The original Java component of the project. AOP Proxy – Generates Java objects from the AOP framework. AOP Proxy

simultaneously. In principle, the caller calls directly the AOP container dynamically generated proxy object, and then the proxy object calls the target object to complete the original business logic processing, and the proxy object has already synthesized the tangent plane and the business logic method.Some of the concepts that are covered in figure 6-6 are explained below.Facets (Aspect): In fact, the realization of common functions. such as log plane, permission plane, transaction plane, and

attributes of things. Faceted search can be seen as a combination of search and browse. As an effective search method, faceted search has been used in many aspects such as e-commerce, music, tourism and so on.For example, Google Music's pick song page, divides the song into rhythm, tone, tone, age, genre and other facets Count based on file matching with search For example, the e-commerce website depends on the style, leng

Before we talked about the Elasticsearch (search engine) operation, such as: Add, delete, change, check and other operations are used Elasticsearch language commands, like SQL command, of course Elasticsearch Official also provides a python operation Elasticsearch (search engine) interface package, just like the SQLAlc

Right-click the project and click Properties->project FacetsIf you can see the project as web2.3 java1.5 of course we can also change to the version we need, open the XML file My-app-web/.settings/org.eclipse.wst.common.project.facet.core.xml, modify it:XML code XML version="1.0" encoding="UTF-8"?> Faceted-project > fixed facet="Wst.jsdt.web"/> installed facet="java" version="1.8"/> installed facet="Jst.web" version="3.0"/> installed facet="Wst.jsdt.web" version="1.0"/>

1. AOP Concept: Aspect-oriented programming, refers to the extension function does not modify the source code, the function code is separated from the business logic code.Main functions: Logging, performance statistics, security control, transaction processing, exception handling and so on.The main intent: to divide the code of logging, performance statistics, security control, transaction processing, exception handling, and so forth from the business logic code, through the separation of these

Springboot provides powerful AOP support, and we've explained AOP-oriented facets, so here's how the specific AOP principle complements the specific description;AOP aspect is mainly cut method, we usually engage in some log analysis and transaction operations, to use the plane, similar to interceptors;@Aspect annotations are facet annotation classes@Pointcut tangency Definition@Before is called before the method executes@After is called after the meth

AOP is the Aspect oriented program for slicing. In the AOP thought, the function is divided into the core business function and the periphery function.The so-called core business, such as landing, adding data, deleting data is called the core business.The so-called peripheral functions, such as performance statistics, logging, transaction management and so on.The perimeter function is defined as a slice in spring's aspect-oriented programming AOP idea . In the AOP idea, the core business functio
