c3p0.properties要放在src目录下!配置成功后,测试显示c3p0比dbcp还快!基本就是这个速度:
通过数据库直连-----1523858360516-1523858360203=313
通过dbcp连接池----1523858360617-1523858360516=101
通过c3p0连接池----1523858360637-1523858360617=20

MySQL储存过程的具体实现在于 SQL语句的执行。jdbc通过连接类com.mysql.jdbc.Driver连接到MySQL,然后执行SQL语句;即实现了储存过程。Navicat是MySQL可视化工具,在Navicat中创建的储存过程会直接映射到MySQL中。至于为什么可以jdbc可以调用到,是因为jdbc连接着MySQL。具体的机制(个人理解):应该是数据同步共享。
