You can do something like this...

@Autowired
JsonViewTemplateEngine templateEngine

void myMethod() {
    Template t = templateEngine.resolveTemplate('/book/show')
    def writable = t.make(book: new Book(title:"The Stand"))
    def fw = new FileWriter(...)
    writable.writeTo( fw )
    ...
}

Of course in a controller you don't need to mark the engine with `@Autowired` but I included that to clarify where the engine is coming from. – Jeff Scott Brown Feb 19 '18 at 19:38

Another simple option would be:

def action() {
    def json = [ key1:'value1', key2:[ key21:'value21' ]
    new File( '/the/path' ).withOutputStream{ it << ( json as JSON ) }
    [ some:result ]
}
