java 调用 Tomcat 中的 ConnectionPool 通过Context 中去查找 jndi 的方式 那么目标就明确了 Java ==jndi==> Tomcat ===> Databases 1) 因为是连接池所以需要$CATALINA_HOME/lib/tomcat-dbcp.jar 包 把这个jar 包放到对就的Tomcat 目录下当然一般Tomcat 目录下有。 2) 要连接数据库 所以要jdbc 驱动$CATALINA...
首先,在这里:http://tomcat.apache.org/我们点击左侧导航栏中“Documentation”下的Tomcat 7.0,进入到这个链接中:http://tomcat.apache.org/tomcat-7.0-doc/index.html,详细的信息我们不用都看,在左侧导航栏中有一个链接Configuration,我们点进去之后,再点击其左侧导航栏中connector一项的HTTP,就进入到HTTP连接数及其...
tomcat-jdbc-pool的特色 基于jdk1.5后的并发实现。代码简洁,精练。核心的类就2,3个。 对池的控制就在org.apache.tomcat.jdbc.pool.ConnectionPool中搞定。 先前有简单看过 dbcp1.x, c3p0等等,代码量真不少,逻辑复杂。 想熟悉池的设计,可以仔细读读tomcat-jdbc-pool,非常快速的入手。在dbcp2的实现时,跟tomcat...
