Hibernate number Precision

When you map an entity through hibernate, the corresponding primary key type in the corresponding Pojo class is generated based on the precision of the number type in the database. Following the results of the pro-test:

Number ( 1 )

A Boolean is generated in the Pojo class

Public class Test implements java.io.Serializable { Fields Private Boolean ID; }

Number ( 2 )

A byte is generated in the Pojo class

Public class Test implements java.io.Serializable { Private Byte ID; }

Number ( 3 ) Number ( 4 )

Short

Number ( 5 ) Number ( 6 ) Number ( 7 ) Number ( 8 )

Number ( 9 )

Integer

Number ( Ten ) Number ( One ) Number ( A ) Number ( - )

Number ( - ) Number ( the ) Number ( - ) Number ( - )

Number ( - )

Long

Number ( + ) ----- Number ( - )

When number has no precision, the default 38-bit
