add log4jdbc function

Before add it will see sql logs in console:
```sql
select shop0_.id as id1_0_0_, shop0_.employees_number as employee2_0_0_, shop0_.name as name3_0_0_ 
from shops shop0_ where shop0_.id=?
```
After will see sql logs in console:
```sql
11:49:10.169 [http-bio-8080-exec-4] INFO  jdbc.sqltiming - select shop0_.id as id1_0_0_, shop0_.employees_number as employee2_0_0_, shop0_.name as name3_0_0_ 
from shops shop0_ where shop0_.id=7 
 {executed in 2 msec}
```
Add log4jdbc will be more convenient for debug.
