在调试及jeecmsv6开源框架的时候遇到ERROR org.hibernate.util.JDBCExceptionReporter - An attempt by a client to checkout a Connection has timed out这个错误，该怎么解决？

数据库链接不上，你什么数据库

回复第2楼mysql,工程在其他电脑上已经可以实现，拷贝到我电脑上就报了这个错误

那说明数据库配置文件你没改，和你数据库实际地址对不上，你要去修改web-inf/config下的jdbc.properties

回复第4楼#mysql\u914d\u7f6e
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1/jeecmsv6?characterEncoding=UTF-8
jdbc.username=root
jdbc.password=root

hibernate.db=mysql
hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect

hibernate.hbm.jeecms.core=classpath*:/com/jeecms/core/entity/hbm/*.hbm.xml
hibernate.hbm.jeecms.cms=classpath*:/com/jeecms/cms/entity/main/hbm/*.hbm.xml
hibernate.hbm.jeecms.assist=classpath*:/com/jeecms/cms/entity/assist/hbm/*.hbm.xml

cpool.checkoutTimeout=5000
cpool.minPoolSize=20
cpool.maxPoolSize=50

cpool.maxIdleTime=7200
cpool.maxIdleTimeExcessConnections=1800
cpool.acquireIncrement=10没什么错误啊

没错误就不可能链接不上数据库，你把完整的报错截图看下
