项目的熟悉

今天是继续熟悉项目，总算把项目的数据库连接这块看懂了,连接项目的信息放在jdbc.property 里

jdbc.dataBase=mysql                                        //连接的数据库
jdbc.driver=com.mysql.jdbc.Driver                          //连接的数据驱动
jdbc.url=jdbc:mysql://ziliao:3306/db_trainmanage?useUnicode=true&characterEncoding=UTF-8  //连接的地址
jdbc.username=root                                      //连接的用户名
jdbc.password=root                                      //连接的密码


# Time to wait for an open connection before timing out
# (in milliseconds)
pool.checkoutTimeout=10000

# Connection pool size
pool.minPoolSize=5
pool.maxPoolSize=50

# How long to keep unused connections around(in seconds)
# Note: MySQL times out idle connections after 8 hours(28,800 seconds)
# so ensure this value is below MySQL idle timeout
pool.maxIdleTime=25200

# How long to hang on to excess unused connections after traffic spike
# (in seconds)
pool.maxIdleTimeExcessConnections=1800

# Acquiring new connections is slow, so eagerly retrieve extra connections
# when current pool size is reached
pool.acquireIncrement=5
