Spring uses @autowired annotations to automatically assemble in the previous articleSpring Learning (iii)-----Spring automatic assembly Beansexample, it will match the properties of any bean in the current spring container automatically assembled. In most cases, you may only need to automatically assemble properties in

annotation injection, as the name implies, is injected through annotations, and the common annotations associated with spring and injection are autowired, Resource, Qualifier, Service, Controller, Repository, Component. Autowired is auto-injected and automatically finds the right bean from the spring context t

The traditional spring approach is to use an. xml file to inject beans or to configure AOP and things, and there are two drawbacks to doing so:1. If all the content is configured in the. xml file, the. xml file will be very large, and if the. xml file is separated by demand, then the. xml file will be much larger. In summary, this causes the readability and maintainability of the configuration file to become very low.2. Switching between. java files a

Can spring annotations perceive each other ?, Spring annotation awareness Currently, spring mvc is used to write a remote control tool. Today I wrote two classes of dao layer, and then extracted a dao layer interface. When exporting the interface, the annotation @ Transactional of the original class is also exported t

The annotation mechanism can be used in spring instead of the traditional configuration of a bean in XML.Such as[Java]View Plain copy "code" class="java" >@Component Public class loadmessagejob{ //Code } and @Component the first letter of the default class name becomes the Bean's ID, and the last two need to be scanned for the package to take effect, Implement the Applicationcontextaware interface to implement the Setap

When using spring AOP, it is necessary to determine the annotations on the target method, such as caching, authentication permissions, etc.Custom annotations Packagecom.agent.annotation;ImportJava.lang.annotation.ElementType;Importjava.lang.annotation.Retention;ImportJava.lang.annotation.RetentionPolicy;ImportJava.lang.annotation.Target;Importorg.springframework.

Spring Common annotationsUsing annotations to construct an IOC containeruse annotations to register beans with the spring container. You need to register .such as: Specify a package in Base-package1 Context:component-scanbase-package= "Cn.gacl.java"/>Indicates the Cn.gacl.java package and its child packages, if a class

MyBatis provides several annotations such as: @InsertProvider, @UpdateProvider, @DeleteProvider and @selectprovider, These are the ways to build dynamic languages and let MyBatis perform these languages using annotation-based mybatis, or better.First is to define Mapper, @ Selectprovider to declare class (Citysqlprovide) and method name (findbystate), Public Interface Citymapper { = citysqlprovide.

Starting with 3.1, spring introduced support for the cache. The methods and principles used are similar to spring's support for transaction management. Spring Cache is a method of action, and the core idea is that when we call a caching method, the method parameter and the return result are stored in the cache as a key-value pair, and the method is no longer executed the next time the same parameter is invo

transaction management is built on the AOP. The essence is to intercept the method before and after it, and then create or join a transaction before the target method starts, committing or rolling back the transaction according to execution after the target method is executed. The greatest advantage of declarative transactions is that you do not need to programmatically manage transactions, so that you do not need to doping transaction-managed code in your business logic code, just make relevan
