-------------------------------------
Summary: camel-rest-openapi: Input and output types binding to
java classes using $ref or title of the schema
Key: CAMEL-21478
URL: https://issues.apache.org/jira/browse/CAMEL-21478
Project: Camel
Issue Type: Improvement
Components: camel-rest-openapi
Affects Versions: 4.8.1, 4.8.0
Reporter: Chamodya Dias
Currently, camel resolves the Java class names for RestBindingConfiguration
from Schema XML attribute.
Implemented at: org.apache.camel.component.rest.openapi.RestOpenApiProcessor
```
private RestBindingConfiguration createRestBindingConfiguration(Operation o)
throws Exception {
...
...
Schema s = m.getValue().getSchema();
// $ref is null, so we need to know the schema name via XML
if (s != null && s.getXml() != null) {
String ref = s.getXml().getName();
...
```
But the documentation says Camel can resolve the schema from the schema name:
https://camel.apache.org/manual/rest-dsl-openapi.html#_binding_to_pojo_classes
This improvement suggests adding an `else-if` condition that uses `$ref` to
resolve the schema name if available or another `else-if` condition that uses
the `title` attribute of the schema to get the class name if available.
Also, the current implementation doesn't resolve class names when using the
`requestBodies` component directly in the OAS. It only uses `content` attribute.
example:
```
requestBody:
$ref: '#/components/requestBodies/createProduct'
```
This improvement suggests the capability to add this also.
