在Spring Boot应用程序中,我们可以使用HikariCP来管理数据库连接。连接超时(connectionTimeout)是一个配置属性,用于指定在连接池中获取连接时的等待时间。如果在指定的时间内无法获取到可用的连接,则会抛出连接超时的异常。 连接超时的配置可以在应用程序的配置文件中进行设置。可以使用以下属性来配置连接超时: sprin
In production-ready implementations, a connection pool should provide a bunch of extra features, such as the ability to track the connections that are currently in use, support for prepared statement pooling, and so forth. In order to keep this article simple, we’ll omit how to implement the...

1. Setting Up Hikari with Spring Boot Hikari is the default DataSource implementation with Spring Boot 2. This means we need not add explicit dependency in the pom.xml. To sum up, you require no other steps with Spring Boot 2.. To use Hikari connection pooling, add the following dependenc...
Database connections are expensive in terms of resources.Connection pooling is a good strategy to manage and configure these connections.In short, they can reduce the costs of connection life cycles. AllJava connection poolingframeworks have their own connection validation implementation. Additionally, mo...
