Chapter 232. MSV Component Available as of Camel version 1.1 The MSV component performs XML validation of the message body using the MSV Library and any of the supported XML schema languages, such as XML Schema or RelaxNG XML Syntax . Maven users will need to add the following dependency to their pom.xml for this component: <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-msv</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency> Note that the Jing component also supports RelaxNG Compact Syntax 232.1. URI format msv:someLocalOrRemoteResource[?options] 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. For example msv:org/foo/bar.rng msv:file:../foo/bar.rng msv:http://acme.com/cheese.rng You can append query options to the URI in the following format, ?option=value&option=value&... 232.2. Options The MSV component supports 3 options, which are listed below. Name Description Default Type schemaFactory (advanced) To use the javax.xml.validation.SchemaFactory. SchemaFactory resourceResolverFactory (advanced) To use a custom LSResourceResolver which depends on a dynamic endpoint resource URI ValidatorResource ResolverFactory resolveProperty Placeholders (advanced) Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true boolean The MSV endpoint is configured using URI syntax: with the following path and query parameters: 232.2.1. 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 232.2.2. Query Parameters (11 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 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. ValidatorResource ResolverFactory 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 synchronous (advanced) Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). false boolean useDom (advanced) Whether DOMSource/DOMResult or SaxSource/SaxResult should be used by the validator. false boolean 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 232.3. Spring Boot Auto-Configuration The component supports 4 options, which are listed below. Name Description Default Type camel.component.msv.enabled Enable msv component true Boolean camel.component.msv.resolve-property-placeholders Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true Boolean camel.component.msv.resource-resolver-factory To use a custom LSResourceResolver which depends on a dynamic endpoint resource URI. The option is a org.apache.camel.component.validator.ValidatorResourceResolverFactory type. String camel.component.msv.schema-factory To use the javax.xml.validation.SchemaFactory. The option is a javax.xml.validation.SchemaFactory type. String 232.4. 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 RelaxNG XML Schema (which is supplied on the classpath). 232.5.
