Validator

URI format

validator:someLocalOrRemoteResource

Where someLocalOrRemoteResource is some URL to a local resource on the classpath or a full URL to a remote resource or resource on the file system which contains the XSD to validate against. For example:

msv:org/foo/bar.xsd
msv:file:../foo/bar.xsd
msv:http://acme.com/cheese.xsd
validator:com/mypackage/myschema.xsd

The Validation component is provided directly in the camel-core.

Options

The Validator component supports 3 options, which are listed below.

Name	Description	Default	Type
lazyStartProducer (producer)	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.	false	boolean
autowiredEnabled (advanced)	Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.	true	boolean
resourceResolverFactory (advanced)	To use a custom LSResourceResolver which depends on a dynamic endpoint resource URI		ValidatorResourceResolverFactory

autowiredEnabled (advanced)

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

boolean

resourceResolverFactory (advanced)

To use a custom LSResourceResolver which depends on a dynamic endpoint resource URI

ValidatorResourceResolverFactory

The Validator endpoint is configured using URI syntax:

validator:resourceUri

with the following path and query parameters:

Path Parameters (1 parameters):

Name	Description	Default	Type
resourceUri	Required URL to a local resource on the classpath, or a reference to lookup a bean in the Registry, or a full URL to a remote resource or resource on the file system which contains the XSD to validate against.		String

Type

resourceUri

Required URL to a local resource on the classpath, or a reference to lookup a bean in the Registry, or a full URL to a remote resource or resource on the file system which contains the XSD to validate against.

String

Query Parameters (10 parameters):

Name	Description	Default	Type
failOnNullBody (producer)	Whether to fail if no body exists.	true	boolean
failOnNullHeader (producer)	Whether to fail if no header exists when validating against a header.	true	boolean
headerName (producer)	To validate against a header instead of the message body.		String
lazyStartProducer (producer)	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.	false	boolean
errorHandler (advanced)	To use a custom org.apache.camel.processor.validation.ValidatorErrorHandler. The default error handler captures the errors and throws an exception.		ValidatorErrorHandler
resourceResolver (advanced)	To use a custom LSResourceResolver. Do not use together with resourceResolverFactory		LSResourceResolver
resourceResolverFactory (advanced)	To use a custom LSResourceResolver which depends on a dynamic endpoint resource URI. The default resource resolver factory resturns a resource resolver which can read files from the class path and file system. Do not use together with resourceResolver.		ValidatorResourceResolverFactory
schemaFactory (advanced)	To use a custom javax.xml.validation.SchemaFactory		SchemaFactory
schemaLanguage (advanced)	Configures the W3C XML Schema Namespace URI.	http://www.w3.org/2001/XMLSchema	String
useSharedSchema (advanced)	Whether the Schema instance should be shared or not. This option is introduced to work around a JDK 1.6.x bug. Xerces should not have this issue.	true	boolean

Example

The following example shows how to configure a route from endpoint direct:start which then goes to one of two endpoints, either mock:valid or mock:invalid based on whether or not the XML matches the given schema (which is supplied on the classpath).

Advanced: JMX method clearCachedSchema

You can force that the cached schema in the validator endpoint is cleared and reread with the next process call with the JMX operation clearCachedSchema. You can also use this method to programmatically clear the cache. This method is available on the ValidatorEndpoint class.

Spring Boot Auto-Configuration

When using validator with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-validator-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>
