How to assign all matching properties from Groovy object to Java object?

Question

I want to use Groovy with JDBC to load some data from a table. I then want to copy the properties across where the property names match. How can I do this in Groovy?

In addition to topchef's answer, you might be able to use some groovy map magic

If you limit your sql to the properties in your Java Class (and assuming you can hold the entire result in memory at once), then you should be able to use the rows method to get a List of GroovyRowResult objects (one per row). As this class is an instance of Map, groovy will use it to construct your java object automatically for you:

class MyJavaClass {
  String property1, property2, property3
}

sql.rows("select property1, property2, property3 from temp_table").each { row ->
   MyJavaClass e = row
}
