First, hibernate. cfg. xml is generally placed in the src directory.

The self-built connection pool of Hiberate has only test value and is not recommended for actual projects. You can use the C3p0 or Proxool connection pool in the actual project. To use the c3p0 connection pool or proxool connection pool, you only need to configure the attributes in these connection pool configurations instead of hiberate. connection. pool_size.

The above example uses the c3p0 data source, so you also need to add the JAR package under the c3p0 directory of the optional subdirectory of hiberate-distribution-3.6.0.Final \ lib to the class loading path of the system.
