camel-component-validator

Validator component for rust-camel (XSD, JSON Schema, YAML)

Overview

Validator component for rust-camel (XSD, JSON Schema, YAML).

Validator component for rust-camel supporting XSD, JSON Schema, and YAML schema validation.

Usage

// Validate XML body against XSD schema
route!{
    from("timer:tick?repeatCount=1")
    .to("validator:schemas/order.xsd")
}

// Validate JSON body
route!{
    from("timer:tick?repeatCount=1")
    .to("validator:schemas/order.json")
}

// Fail silently on empty body
route!{
    from("kafka:input")
    .to("validator:schemas/order.xsd?failOnNullBody=false")
}

URI format

validator:path/to/schema[?type=xml|json|yaml&failOnNullBody=true|false&headerName=X-Header&failOnNullHeader=true|false]

If type is omitted, schema type is inferred from file extension.

URI options

Option	Default	Description
`type`	(from extension)	Schema type: `xml`, `json`, `yaml`
`maxPayloadBytes`	(none)	Reject bodies larger than this
`failOnNullBody`	`true`	Reject empty bodies when `true`
`headerName`	(none)	Validate a header value instead of the body
`failOnNullHeader`	`true`	Reject when the named header is missing

Startup behavior

Schema is compiled and cached on first validation call.

Build requirement

XSD validation is delegated to xml-bridge (gRPC backend) and no longer depends on libxml2 in this crate. The bridge process is cleaned up when the Camel context stops via the Lifecycle service.
