日志如何开启

开启事务日志：

logging.level.org.springframework.transaction.interceptor=TRACE

输出格式如下：

2012-08-22 18:50:00,031 TRACE - Getting transaction for [com.MyClass.myMethod]

[my own log statements from method com.MyClass.myMethod]

2012-08-22 18:50:00,142 TRACE - Completing transaction for [com.MyClass.myMethod]

Session Metrics
