Hikaricp java class library framework
HikaricP is a high -performance Java connection pool library, which aims to provide stable, reliable and efficient database connection pool management.This article introduces the basic characteristics and usage methods of the HikaricP framework, and provides some Java code examples.
Hikaricp was created by Japanese developer BrettWoolDridge. It performed well in terms of performance and is one of the fastest Java connection pools.Its design concept is simple, lightweight and configurable, which makes it very suitable for applications of various scale.
The main features of HikaricP include:
1. High performance: HikaricP uses multiple optimization technologies to achieve excellent performance.It uses lock -free data structure and asynchronous I/O technologies, thereby improving the efficiency of connection acquisition and release.
2. Simple and easy to use: HikaricP has simple API and easy -to -understand configuration.It provides a simple method to create and manage database connection pool without the need for tedious configuration.
3. Quickly start and recovery: The start and recovery speed of HikaricP is very fast.It uses inert connections and automatic connection verification technologies to minimize the time of the application and restart with minimizing applications.
The following is a Java code example using the HikaricP connection pool:
First, we need to add the dependencies of the Hikaricp library.In the pom.xml file of the Maven project, add the following code:
<dependencies>
<dependency>
<groupId>com.zaxxer</groupId>
<artifactId>HikariCP</artifactId>
<version>4.0.3</version>
</dependency>
</dependencies>
Next, we can use the HikaricP connection pool in the Java code.The following example demonstrates how to create and configure a HikaricP connection pool:
import com.zaxxer.hikari.HikariConfig;
import com.zaxxer.hikari.HikariDataSource;
import java.sql.Connection;
import java.sql.SQLException;
public class HikariExample {
public static void main(String[] args) throws SQLException {
HikariConfig config = new HikariConfig();
config.setJdbcUrl("jdbc:mysql://localhost:3306/mydb");
config.setUsername("username");
config.setPassword("password");
HikariDataSource dataSource = new HikariDataSource(config);
Connection connection = null;
try {
connection = dataSource.getConnection();
// Execute the database operation
} finally {
if (connection != null) {
connection.close();
}
dataSource.close();
}
}
}
In the above example, we first created a Hikariconfig object and set the URL, username and password of the database.Then, by using Hikariconfig to create a HikaridataSource object, this is the core object of the connection pool.
In Try-Finally block, we get a connection from the data source and perform database operations.Finally, don't forget to close the connection and data source in the Finally block to release resources.
Summarize:
This article introduces the basic features and usage methods of the HikaricP framework, and provides a simple Java code example to demonstrate how to use the HikaricP connection pool.HikaricP is an excellent performance, easy -to -use Java connection pool library. If you need to manage database connections in Java applications, it is a choice worth considering.
