public class Main
extends org.javagen.agile.core.ioc.spring.SpringMain

Loads RevGen configuration and executes code generation pipeline using Spring framework IoC BeanFactory.

This class excepts two arguments: revgen.properties and RevGenSpringConfig.xml.

revgen.properties is meant to be the first (ie easiest) level of RevGen configuration specifying:

• Database connection properties
• Generated project name and directory location
• Source folder layout
• Output types: annotations vs XML, Hibernate vs Spring vs EJB3 implementations, etc.
• The global overwrite policy (aka overwriteAll)

Any type of configuration can be achieved using RevGenSpringConfig.xml including:

• Pipeline components and order of execution
• Template names, locations and types and their artifact naming patterns and relative output locations
• Per-template overwrite predicates
• Binding templates to model instances
• Root structure of model tree including global properties and parent containers for generated model instances
• Default and artifact-specific naming patterns using model and emitter contexts
• Reading, writing and merging of metadata
• Database table selection
• Code naming and conversion implementations
• Anything that revgen.properties can specify

Properties inputs have the following precedence from lowest to highest:

1. Properties specified in the GlobalPropertyHolder bean within the RevGenSpringConfig.xml file.
2. Properties specified in the external propertyFile. Note: this can be specified as a GlobalPropertyHolder property and overridden here.
3. Properties specified in the properties instance. Note: these are usually set by the invoking tool (i.e. Maven).

This is an extremely flexible way to configure the code generator, avoiding a one-size-fits-all approach.

public static void main(String[] args)
                 throws Exception

Loads and runs RevGen using Spring configuration file. RevGen is started by invoking the pipeline bean.

Parameters:

args - takes an optional Spring XML configuration file location and/or a properties file. Files can be any valid URL or classpath location. File types are recognized by their extension, names and order are not important. Here are some valid examples:

• file:src/revgen/RevGenSpringConfig.xml
• classpath:RevGenSpringConfig.xml
• file:src/revgen/revgen.properties
• classpath:revgen.properties

Throws:

Exception
