Camel Spring XML Auto Configuration

This is only applicable when using Spring XML files with the camel-spring-xml JAR.

A spring XML file is the XML files that uses <beans> as root tag and have an embedded <camelContext>. This is the classic way of using XML DSL with Apache Camel. That was implemented before Spring Boot.

If you use Camel on Spring Boot, then look at Camel Context Auto Configuration instead.

Autoconfiguration of Optional Services

Camel will configure these functions by doing a lookup in the Spring bean registry to find beans of the given type.

The following list all requires at most one bean defined. If there is more than one bean of this type, then Camel will not use it.
