The application and practice of HikaricP Java6 framework in the Java class library connection pool
HikaricP is a high -performance Java connection pool framework, which has been widely used and practiced.In the Java class library, connecting pool is an important technology that can effectively manage database connections and improve the performance and stability of the system.Hikaricp provides a fast and efficient connection pool implementation that can help developers easily use the connection pool technology in the project.
When using HikaricP to configure the connection pool, you need to add HikaricP dependency items to the project dependency management tool.The following is a pom.xml configuration example of a Maven project:
<dependency>
<groupId>com.zaxxer</groupId>
<artifactId>HikariCP</artifactId>
<version>4.0.3</version>
</dependency>
Next, you can configure HikaricP in the configuration file of the project. For example, in the Spring Boot project, you can configure in the Application.properties or Application.yml file:
properties
# Hikaricp configuration
spring.datasource.hikari.connection-timeout=30000
spring.datasource.hikari.maximum-pool-size=10
spring.datasource.hikari.idle-timeout=600000
spring.datasource.hikari.poolName=SpringBootHikariCP
Then, in the Java class library, HikaricP is used to manage the database connection. You can obtain the database connection through the HikaridataSource object and perform the corresponding database operation.The following is a simple sample code:
import com.zaxxer.hikari.HikariConfig;
import com.zaxxer.hikari.HikariDataSource;
import javax.sql.DataSource;
import java.sql.*;
public class HikariCPExample {
public static void main(String[] args) {
HikariConfig config = new HikariConfig();
config.setJdbcUrl("jdbc:mysql://localhost:3306/test");
config.setUsername("username");
config.setPassword("password");
DataSource dataSource = new HikariDataSource(config);
try (Connection connection = dataSource.getConnection()) {
Statement statement = connection.createStatement();
ResultSet resultSet = statement.executeQuery("SELECT * FROM users");
while (resultSet.next()) {
System.out.println("ID: " + resultSet.getInt("id") + ", Name: " + resultSet.getString("name"));
}
} catch (SQLException e) {
e.printStackTrace();
}
}
}
In the above sample code, a Hikariconfig object is first created, the connection information of the database is set, and then the database connection is obtained through the Hikaridatasource object, and a simple query operation is performed.
In general, the application and practice of HikaricP in the Java library mainly include management that dependence on management, configuration and database connection.By using HIKARICP, developers can more conveniently implement the management of connecting pools to improve the performance and stability of the system.
