spring-:implementations-of-ApplicationContext

The Spring framework provides the implementation of multiple ApplicationContext interfaces to adapt to different application scenarios and application types. The following is the key implementation subdivision: 1. Configuration based on annotations AnnotionConfigapplicationContext It is used for independent implementation of Java configuration (@Configuration,@Bean,@Component, etc.). Very suitable for modern Spring applications, these applications do not use XML configuration. Commonly used in Spring Boot or independent applications. 2. Based on XML configuration Classpathxmla

java-core-: programming-to-an-interface

Interface programming rather than class programming is the best practice, because it improves the flexibility and scalability of the code, and follows the core principles of object -oriented programming (OOP). The following are some reasons: 1. Promote abstraction Interface definition contract: What should interface specifies should be done, not what should be done. This abstract decoupling client code (dependence on interface) and specific implementation. For interface programming, you focus on defining behaviors rather than specific implementation. 2. Support the principle of dependencies (solid) Relying on inverted principles (DIP): high -level modules (business logic) should not depend on low -level modules (implementation); both should rely on abstraction (interface). For example: Paymentpr

spring-: why-spring-cannot-match-by-name-for-injection

Spring dependency injection: Why can't it be matched automatically by the name? Spring's dependency injection mechanism is mainly based on type, not names. When encountering multiple types of the same type (such as TenantDataSource), it will not automatically return to match according to the parameter name. This is because Spring cannot always guarantee the parameter name in the method to match the Bean name. Java will not retain the parameter name in the bytecode compiled by default. If there is no special configuration, parameter names (for example, Tenantadatasource and TenantbDataSource) will be cleared during the compilation period and replaced them with universal names, such as

spring-: @Configuration-in-depth

In -depth understanding of @Configuration annotation in the Spring framework The @Configuration annotation in the Spring framework is used to mark the source defined by a class. In Spring's Java -based configuration, this annotation is very important. It allows developers to configure the application context without XML. When a class is annotated with @Configuration, Spring will treat it as a configuration class and processes it to generate and manage Spring Bean. This type usually contains one or more methods with @Bean annotation, which defines bean managed by Spring container. @Configur

spring-: who-calls-setBeanName()?

The Spring framework is in the Bean initialization stage. As part of the Spring Bean life cycle, SetBeanname (String Beanname) method is called. If Bean implement the Beannameaware interface, this will automatically happen. The following is a detailed explanation of when the setbeanname () method, who, and how to call: Who calls setbeanname ()? Spring IOC (control reversal) container call setbeanname (). When bean is initialized and registered to the Spring context, the Spring container will check whether bean has achieved BE

SET in Java

Detailed explanation of Java Set: The collection of the unique element efficiently This article will explore the SET interfaces and its main implementation classes in Java to help you understand how to efficiently handle a collection that does not include duplicate elements. Source: https://www.devmedia.com.br/java-Collections-Como-Utilizar-Collections/18450 1. Java Set interface introduction The SET interface is a set that does not allow duplicate elements. It is based on a collection of mathematical operations (collections, intersections, and differences), which is very suitable for the need to ensure the uniqueness of the element. Main features: Repeated elements are not allowed. Can store
