Druid首先是一个数据库连接池。Druid是目前最好的数据库连接池,在功能、性能、扩展性方面,都超过其他数据库连接池,包括DBCP、C3P0、BoneCP、Proxool、JBoss DataSource。

Druid已经在阿里巴巴部署了超过600个应用,经过一年多生产环境大规模部署的严苛考验。

同时Druid不仅仅是一个数据库连接池,它包括四个部分:
Druid是一个JDBC组件,它包括三个部分:

  • 基于Filter-Chain模式的插件体系。
  • DruidDataSource 高效可管理的数据库连接池。
  • SQLParser

Druid可以做什么?

  • 替换DBCP和C3P0。Druid提供了一个高效、功能强大、可扩展性好的数据库连接池。
  • 可以监控数据库访问性能,Druid内置提供了一个功能强大的StatFilter插件,能够详细统计SQL的执行性能,这对于线上分析数据库访问性能有帮助。
  • 数据库密码加密。直接把数据库密码写在配置文件中,这是不好的行为,容易导致安全问题。DruidDruiver和DruidDataSource都支持PasswordCallback。
  • SQL执行日志,Druid提供了不同的LogFilter,能够支持Common-Logging、Log4j和JdkLog,你可以按需要选择相应的LogFilter,监控你应用的数据库访问情况。
  • 扩展JDBC,如果你要对JDBC层有编程的需求,可以通过Druid提供的Filter机制,很方便编写JDBC层的扩展插件。
