Disable the Number to String automatic conversion in jackson

问题

When I make a json request to a spring boot backend, Jackson is automatically converting numbers to strings. Is there a way to prevent that?

For example:

JSON

{
    "numberAsString": 123
}

JAVA

private String numberAsString;

after binding json value to the java field numberAsString is equal to "123". i need to prevent this automatic conversion and need to throw some kind of a exception when this happens.
