MiddleGen-Hibernate-R5 configuration

MiddleGen Hibernate configuration

Hibernate O / R mapping tool

http://internap.dl.sourceforge.net/sourceforge/hibernate/middlegen-hibernate-r5.zip

You can generate a * .hbm.xml file, is the mapping file required for Hibernate, downloading the MiddleGen Hibernate and decompressed.

Configuring the database as an example of MS SQLServer, JBDC is driven to MSSQLServer (other driver can also be connected, as long as you can connect to MS SQLServer)

1, enter / config / database / directory

2, driver MSSQLSERVER.JAR driver to / lib / directory

3, edit the mssql.xml file, as follows

database username

Database password

Database Owner

database name

Look at other articles say that the above two can be deleted or not fill, but I have the problem that the deletion or value is from the problem.

Edit Middle Gen Hibernate configuration

1, edit build.xml

2, modify the default file, find this line, probably around 22 lines

// Original content, annotation

// Plus

]>

3, edit the root directory name, find this line, about 30 lines

// original content, annotation

/ / Plus, value is the package of you want, such as COM4, ​​edit output, found this line, probably around 210 lines

Destination = "$ {build.gen-src.dir}"

Package = "$ {name} .hibernate"

/ -> // Original content, annotation

Destination = "$ {build.gen-src.dir}"

Package = "$ {name} .test"

/> / / Plus, in the generated XML file, will use com.test as your package

Output directory is /build/gen-src/com/test/*.hbm.xml(- is a corresponding table, named the name you defined by you)

5, define the output directory, find the line, last in the document

Change to the directory structure you want to output, it is best to use your packages as a directory structure

6. When connecting SQL Server, prompt the database connection to success, but say no table, find the line

Appname = "$ {name}"

Prefsdir = "$ {src.dir}"

GUI = "$ {gui}"

DatabaseURL = "$ {database.URL}"

InitialContextFactory = "$ {java.naming.factory.initial}"

ProviderURL = "$ {java.naming.provider.URL}"

DataSourcejndiname = "$ {Datasource.jndi.Name}"

Driver = "$ {database.driver}"

UserName = "$ {database.userid}"

Password = "$ {database.password}"

Schema = "$ {database.schema}" // remove

Catalog = "$ {database.catalog}" // removed, so you can

After testing these two lines can't be deleted, otherwise there is no table, I don't know why? ? ?

All over the configuration

After the configuration is complete, run an Ant in the root directory

There will be a visual operation interface, as shown

The default will generate the corresponding name according to the table name and field name. Of course, you can also define it yourself, you can click [Generate], you can find it.

/BUILD/Gen-src/com/test/*.hbm.xml, generates the corresponding XML file
