IntelliJ IDEA 10 generate entity (POJO) from DB model

Question

How can I generate entity (POJO) from database model using IntelliJ IDEA 10. I create \"Data source\" in IntelliJ but I have not any idea how can I generate the POJO.

Answer 1

The default Scripted Extensions Generate POJOs.groovy is not very good when dealing with tables with underscore(which is very common).

So I make some modifications.

The main code

def calcFields(DasObject table) {
    DasUtil.getColumns(table).reduce([]) { fields, col ->
        def spec = Case.LOWER.apply(col.dataType.specification)
        def typeStr = typeMapping.find { p, t -> p.matcher(spec).find() }.value
        fields += [[
                       name : javaName(col.name, false),
                       type : typeStr,
                       annos: """
    /**
     * $col.comment
     */"""]]
    }
}

static String javaName(String str, boolean capitalize) {
    def s = CaseFormat.LOWER_UNDERSCORE.to(CaseFormat.UPPER_CAMEL, str);
    capitalize || s.length() == 1 ? s : Case.LOWER.apply(s[0]) + s[1..-1]
}
