Component Endpoint Annotations
You can annotate Endpoint and Component classes, so that their configuration documentation can be automatically generated by Maven tooling via the Camel Component Maven Plugin into the src/main/generated folder.
The documentation is then included into the jar as JSON schema files.
The Camel project uses this to automatic keep the website documentation up-to-date with all the latest options on the Camel Components.
Supported Annotations
| Annotation | Description |
|---|---|
| Specifies that an endpoint is annotated with |
| Used to annotate a parameter value; usually specified via ?foo=bar syntax in the URI strings in Camel. Used currently only on field declarations but in the future could be used on setter methods too. If no name is specified then the name of the field/setter property is used. |
| Specifies that a field is a nested object of one or more configuration parameters; then the class of this field should be annotated with one or more |
| Used for special situations to provide additional information. |
For example see the TimerEndpoint from the camel-timer component and notice how it is using these annotations.
The annotations are not only useful for automatically generating the documentation; we can use them to refine the validation of the code during configuration and can be useful for tooling providers, so they can more easily introspect the configuration options.
