He is a protocol droid designed to assist in etiquette and translation, and is fluent in over six million forms of communication. [1][2] The character appears in all nine films of the Skywalker Saga —which includes the original trilogy, the prequel trilogy and the sequel trilogy.

c3p0 is an easy-to-use library for augmenting traditional (DriverManager-based) JDBC drivers with JNDI-bindable DataSources, including DataSources that implement Connection and Statement Pooling, as described by the jdbc3 spec and jdbc2 std extension.

c3p0 is an easy-to-use library for making traditional JDBC drivers "enterprise-ready" by augmenting them with functionality defined by the jdbc3 spec and the optional extensions to jdbc2. c3p0 now also fully supports the jdbc4. In particular, c3p0 provides several useful services:

C-3PO (See-Threepio) was a 3PO-series protocol droid designed to interact with organics, programmed primarily for etiquette and protocol. Sometimes referred to as Threepio, he was fluent in over six million forms of communication, and developed a fussy and worry-prone personality throughout his many decades of operation.

c3p0 is a mature, highly concurrent JDBC Connection pooling library, with support for caching and reuse of PreparedStatement objects. c3p0 is available as managed dependency on Maven Central, [groupId: com.mchange, artifactId: c3p0] For available versions, look here .

2024年1月8日 · In this article, we’ve discussed how to use c3p0 with Hibernate. We’ve looked at some common configuration properties and added c3p0 to a test application. For most environments, we recommend using a connection pool manager such as c3p0 or HikariCP instead of traditional JDBC drivers.

2020年1月12日 · C3P0是一个开源的JDBC连接池，它实现了数据源与JNDI绑定，支持JDBC3规范和实现了JDBC2的标准扩展说明的Connection和Statement池的DataSources对象。 即将用于连接数据库的连接整合在一起形成一个随取随用的数据库连接池（Connection pool）。 当我们在进行基于数据库的web程序开发时，我们可以先在主程序（如Servlet、Bean）中通过JDBC中 …
