Build a table can be reversed with myeclipse to generate the class can also generate mapping files (more convenient)

First-class can set Hibernate property dynamically generated table but the mapping file to choose their own



When doing a project, the data is analyzed first, and a data dictionary is formed. When the data dictionary comes out, we can build the table from the data dictionary to write the SQL statement, or we can write the entity class or entity class mapping file according to the data dictionary, and then generate the data table.
