When discussing transactions, you might think of ACID (Atomicity, Consistency, Isolation, Durability). In MySQL, transaction isolation levels correspond to the Consistency and Isolation properties of ACID. ACID refers to the four properties a database transaction should have. Atomicity: A transaction is an atomic operation that either fully completes or entirely rolls back to the initial state. MySQL’s transaction isolation levels are not directly related to atomicity but achieve it through transaction commit and rollback.

Spring Events Usage Guide Spring events are a mechanism in the Spring framework for implementing an event notification system based on the publish-subscribe pattern within an application. We can use Spring events to achieve simple business decoupling. This article will introduce the usage of Spring Events and related examples based on the SpringFramework 5.3.32 version. Core Components of Spring EventsIn Spring, events are implemented through the following core components:

In the Spring framework, data validation is a common requirement. While Spring provides many built-in validation methods, there are cases where we may need to implement custom validation logic. This blog will show you how to implement a custom Validator in Spring, including a practical example. Introduction to Spring ValidatorThe Validator interface in the Spring framework allows us to implement custom validation logic. This interface primarily contains two methods:

In Java project development, managing resource files such as XML configuration files is a common requirement. Especially when these resource files need to be in the same path as the compiled class files, correctly configuring the project becomes crucial. This article explores how to package XML files into the Java classpath in Maven projects and IntelliJ IDEA. XML Management in Maven ProjectsMaven is a common tool for managing and automating Java project builds.

In the Spring Framework, the @Bean annotation is a powerful tool used for defining and configuring Beans. However, effectively using the @Bean annotation requires understanding its advanced properties and limitations. This article aims to comprehensively analyze the advanced properties of the @Bean annotation and discuss its key limitations to ensure the robustness and effectiveness of Spring applications. Common Properties of the @Bean Annotation Name Description: Specifies the name of the Bean.

Spring Bean instantiation is a fundamental aspect of building applications. Understanding the different Bean instantiation methods is crucial for developing efficient and maintainable applications. This article will delve into the various Bean instantiation methods in Spring, providing corresponding code examples to help you better comprehend and apply these methods. Using ConstructorsCreating Beans through class constructors is the most common approach. The Spring container calls the class constructor and can inject dependencies through constructor arguments.

When using the Spring framework to build enterprise-level applications, understanding and correctly using different Bean scopes is crucial. The framework provides various scopes, with the most commonly used being Spring Singleton and Prototype. This article will help you understand the differences between these two scopes and their use cases through simple examples. Spring Singleton BeanThe Spring container creates a single instance of a Bean for each Spring IoC container. This means that no matter how many times we request it, Spring will provide the same Bean instance.
