What is the paging principle of mybatis?
Mybatis paging principle is:
First, an interceptor interface is defined inside MyBatis
All plug-ins must implement this Interface, let's take a look at the definition of this interface
public interface Interceptor { Object intercept(Invocation invocation) throws Throwable; Object plugin(Object target); void setProperties(Properties properties); }
Then one of the key methods is intercept, so as to achieve interception
The principle of paging plug-in is to use the plug-in interface provided by MyBatis to realize self-interception Define the plug-in, intercept the SQL to be executed in the interception method of the plug-in, and then rewrite the SQL according to the set dialect (dialect) and the set paging parameters, generate SQL with paging statements, and execute the rewritten SQL. To achieve paging
So the principle is still based on the interceptor

The five major features of Java are polymorphism, Lambda expressions, StreamsAPI, generics and exception handling. 1. Polymorphism allows objects of different classes to be used as objects of common base classes. 2. Lambda expressions make the code more concise, especially suitable for handling collections and streams. 3.StreamsAPI efficiently processes large data sets and supports declarative operations. 4. Generics provide type safety and reusability, and type errors are caught during compilation. 5. Exception handling helps handle errors elegantly and write reliable software.

The core components of the JVM include ClassLoader, RuntimeDataArea and ExecutionEngine. 1) ClassLoader is responsible for loading, linking and initializing classes and interfaces. 2) RuntimeDataArea contains MethodArea, Heap, Stack, PCRegister and NativeMethodStacks. 3) ExecutionEngine is composed of Interpreter, JITCompiler and GarbageCollector, responsible for the execution and optimization of bytecode.
