Overview
Generator is an command line application written in java that have the goal to make easy
the construction of little applications that needs some database objects stuff.
It isn't a replacement of complex object persistence solutions, like hibernate or TopLink
but it covers a different target. The little java web applications that dont' use sofisticated
persistence options.
Generator invocation is simple, just type:
java -jar generator.jar -xml (config-file.xml)
where config-file is a xml config file with the definitions to connect to the database and generate
the bean classes.
The most important features of Generator are (version 2.1.3):
- Generates classes to access via custom connection resources to database tables.
- Configuration files are in clear xml format and can be embedded or separate.
- Supports individual or global field updates.
- Supports custom set of Exceptions.
- Provides toXML function for each entity generated.
- Provides toJson function for finders and general query results.
- Provides automatic generation of finders coonfigured in the xml configuration file.
- Provides some utility static methods via the BdUtils.java class generation.
- Generates an xml file with the database structure.
- Supports configuration of the methods that produces XML (String as CDATA, data as attributes or values, ...)
- Support for MySQL, Firebird, MS SQL Server, Oracle and H2(H2 support is in initial stage at this moment).
- Provides an ant task for automatic integration builds.
- Supports transparent renaming of the generated class individual fields.
- Supports normal or CDATA output in individual fields.
- Supports utilization in all database methods with your own external connection.
- Preliminar optional support of a pluggable logging system (The goal is use log4j integration)
- Support for SEQUENCES in Oracle, Firebird and H2, AUTOINCREMENT in MySQL and Autonumeric in MSSQL
- Support arbitrary raw code and imports from configuration file
- Correct treatment for NULL values of the fields in the generated class
- Optional cutting of String fields to its max size in Database
For the planned features, you can see them in the above roadmap.
See inside documentation file README.txt for a example config-file.xml.
Roadmap
Versions 2.0.x :
Mature and add features of the application. Standarize build, documentation and so on.
Versions 2.1.x :
Rewrite of documentation. Focus on database compatibility issues and bugs (Planned MySQL, Oracle and MSSQL) and better logging facilities and error control
Versions 2.2.x :
Provide offline work capability with pre-generated database schemas
