Hibernate use Xdoclet to automatically generate configuration files

Many-to-many For example, there are Position and user two tables, a Position can have multiple users, a user can have multiple Position, the middle of the association table is test_user_position. The HBM configuration file is automatically generated by adding Xdoclet to the PO. No nonsense, look at the code.

In MyEclipse Right click Item, choose "Properties", select "Myeclipse/xdoclet" from the interface, click "Add Standard ...", add "Standard Hibernate", click OK, end setting.

Build Hibernate.cfg.xml in projects, configure sessionfactory and data sources

Right-click on the item, select "Myeclipse/run XDoclet", will automatically create the above two classes corresponding to the HBM file.

Note: There is a problem with creating the completed HBM file, which has role and ReadOnly attributes, change the former to name, and the latter to delete it.
