Course Introduction:MyBatis is an excellent persistence layer framework that provides a rich caching mechanism, including first-level cache and second-level cache. This article will comprehensively analyze the caching mechanism of MyBatis from the first level cache to the second level cache, and provide specific code examples. The first-level cache of MyBatis is a SqlSession-based cache, also called a local cache. When executing the same SQL statement and passing in the same parameters, MyBatis will cache the query results in SqlSes

Course Introduction:Level 2 cache and level 3 cache are two common cache levels in computer systems. They have obvious differences in functionality and performance. First of all, the second-level cache is a layer of cache located between the central processing unit (CPU) and the main memory. It usually consists of a high-speed cache (L1) and a secondary cache (L2). The L1 cache is located inside the CPU and has the lowest latency and smallest capacity. It mainly stores data frequently accessed by the CPU core. The L2 cache is located on the CPU chip, has a larger capacity, and stores more data. In contrast, Level 3 mitigation

Course Introduction:MyBatis cache strategy analysis: best practices for first-level cache and second-level cache When developing using MyBatis, we often need to consider the choice of cache strategy. The cache in MyBatis is mainly divided into two types: first-level cache and second-level cache. The first-level cache is a SqlSession-level cache, while the second-level cache is a Mapper-level cache. In practical applications, rational use of these two caches is an important means to improve system performance. This article will use specific code examples to analyze a MyBatis

Course Introduction:Mybatis first-level cache and second-level cache are two different levels of caching mechanisms provided by mybatis. The first-level cache is the cache mechanism enabled by default in mybatis. It is a thread-based local cache, and the second-level cache is based on the namespace level cache. Can be shared by multiple SqlSession objects.

Course Introduction:Detailed explanation of MyBatis caching mechanism: One article to understand the principle of cache storage Introduction When using MyBatis for database access, caching is a very important mechanism, which can effectively reduce access to the database and improve system performance. This article will introduce the caching mechanism of MyBatis in detail, including cache classification, storage principles and specific code examples. 1. Cache classification MyBatis cache is mainly divided into two types: first-level cache and second-level cache. The first-level cache is a SqlSession-level cache. When
