Hikaricp Java6 framework in the Java class library analysis

HikaricP is a high -performance database connection pool framework that is suitable for Java applications.Its technical principles in the Java library mainly include the following aspects: 1. Connection pool management: HikaricP uses a lightweight connection pool management algorithm to reduce the overhead of creating and closing the database connection by maintaining a connected pool.The connection pool will dynamically manage the number of connections according to the needs of the application to ensure that each thread can get a available connection. 2. Quickly acquire connection: HikaricP uses an efficient algorithm, making it possible to get database connections quickly in a multi -threaded environment.It uses many optimization technologies, such as using ConcurrenThashMap instead of traditional vector to manage connections, thereby improving concurrent performance. 3. Resource management: HikaricP pays great attention to the management and recycling of resource, and can automatically detect and recycle database connections with too long free time.It uses a set of automatic recycling strategies to manage the creation and destruction of connection according to the set connection timeout time and minimum free connection. 4. Connection reliability: HikaricP uses some connection reliability strategies to ensure the stability and availability of the connection.For example, when the connection timeout or cannot be used for other reasons, the connection pool will automatically carry out repeated operations to ensure the normal operation of the application. Below is a simple Java code example to show how to use the HikaricP connection pool in Java applications: import com.zaxxer.hikari.HikariConfig; import com.zaxxer.hikari.HikariDataSource; import java.sql.Connection; import java.sql.SQLException; public class HikariCPExample { public static void main(String[] args) { // Create HIKARICP configuration object HikariConfig config = new HikariConfig(); config.setJdbcUrl("jdbc:mysql://localhost:3306/mydb"); config.setUsername("username"); config.setPassword("password"); // Create a data source HikariDataSource dataSource = new HikariDataSource(config); // Get the database connection from the data source try (Connection connection = dataSource.getConnection()) { // Execute the database operation // ... } catch (SQLException e) { e.printStackTrace(); } finally { // Close the data source dataSource.close(); } } } The above code uses the HikaricP connection pool to create a database connection and perform some database operations.It should be noted that after the connection is used, the data source should be closed to release resources. In short, HikaricP is a high -performance database connection pool framework. Through its efficient connection management, fast connection acquisition, automatic resource recovery, and connection reliability guarantee, etc., it provides a reliable and high -performance database connection for Java applicationsPool solution.
