Quickly and efficiently master the Aspect-Oriented Programming applications of Spring in enterprise-level projects, the interview skills of out-of-band lectures, and the enterprise-level spring Spring object-oriented programming (AOP) is the cornerstone of enterprise-level applications. It can be said that if you want to upgrade to a Senior Programmer, this part of knowledge is essential. Here we will talk about this part of knowledge with some specif

Requirement: The width of a div on the page changes as the screen width changes, but its aspect ratio is always 2:1, that is, when the width is 1000px, the height is 500pxAnalysis: Regardless of how the browser window changes, always want to keep the aspect ratio of the target element to maintain 2:1, we first thought may be the use of JS to achieve, but the use of JS to achieve is often more cost-efficient

Spring_aop_xml using aspect to implement dynamic proxies (common)XML uses aspect to implement dynamic proxies This method is more commonly used, and the most important advantage of using annotations is that we do not need to define a pointcut above each method to add pointcut to the description, in the XML only needs to be defined once can be used more.In the above spring_aop_annotation use

"Configure aspect" to enable ASPECTJ-style annotations You must import the ASPECTJ jar package in addition to the spring configuration file, and configure it in two ways; I. Configuring in the schema of a configuration file first step: Add xmlns:aop= "HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA.AOP" to the schemaSecond step: Add two lines to the xsi:schemalocation in the schema: http://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP and http://Www.springframework.org/sc

1, the requirements of the scene before also in the article wrote "Interceptor \ Filter" The difference, the article link, in the actual development process, we may encounter the requirements of the interception request parameters, in this I give a scene.The request parameters of an interface are encrypted, and there are some business-independent data in the request parameter that need to be removed.2, the problem arisesSo how can you achieve as long as the business-related data?First of all, we

called outside. Br/> Solution:Write yourself a Xxservice class (set auto-inject @service), define an update () method inside, the method body is empty,And then@AfterReturning（...）void xxUpdate(){ // 在里面只是调用updateInit（）方法。 updateInit( )}This makes it possible to call the Updateinit () method by calling the update () method Xxservice. notification, enhanced Processing (Advice): Is the function you want, you define it first, and then use it where you want to use it, including a pie

Dom| Server Summary: This article applies aspectj to the development of the Notes database on the Domino server, This enables Domino to have some aspect-oriented features. Keywords: Lotus domino/notes, Lotus Domino diiop for Java, AspectJ. The purpose of this paper is how to apply ASPECTJ to Domino's development so that Domino has some features to face. Based on the actual application of ASPECTJ in Domino project, the author makes a brief

to the map. The reference of the map object is obtained through the BusinessUnitService object. point cut and advice constitute the so-called "Aspect (Aspect )"To read data in the storage media, the OOP method uses a DAO class. in AOP, you define a point cut and an advice in the scope class to read data. the AOP framework injects code in the form of advice, which can be executed or compiled.All in all, whe

Spring_AOP_Annotation use Aspect to implement dynamic proxy, springaopaspect Spring_aop_annotation implementation: 1.1 Add the aop schema to beans. xml. 1.2 Enable Automatic Retrieval of aop in xml 1.3 create a class to implement dynamic proxy 1.4 import the aspectj package. Spring uses the aspect package to implement AOP. Therefore, you need to import this package. Maven pom. xml: 1.5 Use @

Software 152 Liu AnminAOP is the continuation of OOP and is the abbreviation for Aspect oriented programming, meaning aspect-oriented programming. AOP is actually a continuation of the GOF design pattern, and the design pattern pursues the decoupling between the caller and the callee, and AOP can be said to be an implementation of this goal.The implementation of AOP technology, mainly divided into two major

1 AOPOverviewAOP (aspect-oriented programming, aspect-oriented programming ): is a new methodology for traditional OOP ( Object-oriented programming, Object-oriented programming ) complements. The main object of the AOP programming operation is the tangent plane (aspect), while the facets are modular crosscutting concerns .When you apply AOP programming, you st

The camera's aspect is consistent with screen by default and can be set to the specified value by script, as follows:Using Unityengine;Using System.Collections;public class Makecameraviewwequalsh:monobehaviour {Use this for initializationvoid Start () {Gameobject.getcomponent}Update is called once per framevoid Update () {}}At this point the camera's aspect is set to 1, except that the camera viewport shape

Part 4 and 5th of this series discuss how to use Javassist to make local changes to a binary class. This time you will learn to use the framework in a more powerful way to take advantage of Javassist's support for finding all specific methods or fields in bytecode. For the Javassist feature, this feature is at least as important as its ability to specify bytecode in a similar way to source code. Support for the Select substitution operation also helps make javasssist a great tool for adding

1. What I know about AOPAt first glance, there is a lot of terminology, and there is a name for the wind, for the aspect programming, is a useful complement of OOP and so on. Let you at a loss, thought: Not many people and I said that AOP is more difficult. When I look inside, I can only find out: He is a simple and unpretentious application on Java basis, including the IOC (see the Spring IOC (dependency injection, inversion of control) conceptual un

PHP aspect-oriented programming component. We use the MVC framework, such as CI, YII, and cakePHP. one of the reasons is that the code can be easily maintained. However, when the business logic is constantly complicated, the more we call the methods in the model in the controller, the more we use the MVC framework, such as CI, YII, and cakePHP. one of the reasons is that the code can be easily maintained. However, when the business logic is constantl

Detailed description of the Python decorator mode and Aspect-Oriented Programming This article mainly introduces the Python decorator mode and Specific Aspect-oriented programming. In summary, the function of the decorator is to add additional functions for existing objects, this article details all aspects of the decorative device model, and then introduces the knowledge of cross-section programming. For m

Assign the return value of timeit (FOO) to foo. Then, the code that calls Foo () does not need to be modified! #-*-Coding: UTF-8-*-import timedef Foo (): Print 'in Foo () '# define a timer, pass in, return another method def timeit (func) with the timing function appended: # define an embedded packaging function and add the packaging def w

The most important concept of Aspect-Oriented Programming is "separation of concerns )". I have never understood this concept. Today, I recalled Python and Ruby programming knowledge. Make a mark. 1. Start with repeated code. Code is often written, repeated code is often written, the seemingly useless repeated code is often written, and the seemingly useless code has to be written. In application system programming, we often add code for permission ch
