Next, we will use the
jpa-generate-entities-from-tables
command in order
to generate your
Entity
class. You will need to provide the following
Java Database
Connectivity
(
JDBC)
connection information:
• The JDBC URL
• The username and password
• The SQL dialect
• The JDBC driver class name
• The path in the filesystem where the JDBC driver is located
• The package where the entities will be generated
You can specify all the parameters in a one-line command or complete it interactively. The
final command would look like this (line breaks added for readability):
[persistence.xml]$ jpa-generate-entities-from-tables \
--jdbcUrl jdbc:postgresql://localhost:5432/forge \
--hibernateDialect org.hibernate.dialect.PostgreSQLDialect \
--userName jboss \
--userPassword jboss \
--driverLocation c:\\forge\\postgresql-9.3-1101.jdbc41.jar \
