JDBC连接超时,导致数据库操作失败

Solution:

数据库连接字符串加上

String url ="jdbc:mysql://192.168.1.10:3306/tdsdb?autoReconnect=true&failOverReadOnly=false";

!!!!!! [NOT WORK]

investigateseting the MySQL servervariable "wait_timeout" to a high value, rather than the default of 8 hours.


真正起作用的是:

INTERACTIVE_TIMEOUT instead ofWAIT_TIMEOUT

SELECTvariable_name,variable_value FROM information_schema.session_variables WHEREvariable_name LIKE '%timeout%'

或者:

SHOW  GLOBAL VARIABLES LIKE'%timeout%'

修改MySQL的参数了,wait_timeout最大为315360001年,在my.cnf中加入:

[mysqld]
wait_timeout=31536000
interactive_timeout=31536000
