如何在DropWizard中验证单个参数

Question

I want to validate some input parameters in DropWizard as documented here: https://dropwizard.github.io/dropwizard/manual/core.html#validation

This example validates an object's properties, which works fine, but my service doesn't receive an object, but the parameters directly. This is a simplification of my code:

@GET
@Path("/MyResource/{myresourceId}")
public MyResource detail(@PathParam("myresourceId") @Valid @Size(min = 2, max = 5) String myresourceId) {

The @Valid and @Size annotations seem to be ignored in this case. Anyone knows if this is possible and if so how to do it right? Thanks.

Answer 1

It's not possible with those annotations as method parameters. Have a look at this thread .

You might be able to write some AOP code to support this (depending on how you're initializing your resources).
