yaml-validate

Demo app to demonstrate YamlProcessor issues

Installation

mvn clean install

Running

mvn spring-boot:run

Sample yaml

This can be modified here sample.yaml

hello: world
arrayAsArray: ['a', 'b']
emptyString: ""
arrayAsString: "[a,b,c]"
emptyArray: []
emptyElementArray: [""]

Endpoints

$ curl http://localhost:8080/get
arrayAsArray[0]:a {valueInstanceOf=class java.lang.String}

arrayAsArray[1]:b {valueInstanceOf=class java.lang.String}

arrayAsString:[a,b,c] {valueInstanceOf=class java.lang.String}

emptyArray: {valueInstanceOf=class java.lang.String}

emptyElementArray[0]: {valueInstanceOf=class java.lang.String}

emptyString: {valueInstanceOf=class java.lang.String}

hello:world {valueInstanceOf=class java.lang.String}

Inference

It is clear that the emptyArray element is returned as a single string object unlike other Array objects where indexing for the collection is being done
