A new issue[1] is created. I'll analyse the root cause later.

Should we allow such use case? For example, a REST service like below will cause javassist.NotFoundException: training.demo.provider.service.TestRestService.TestBodyParam @RestSchema(schemaId = "testSchema") @RequestMapping(path = "test") public class TestRestService { @PostMapping(path = "post") public String post(@RequestBody TestBodyParam body) { return null == body ? "null" : body.toString(); } public static class TestBodyParam { // fields omitted } } But inner class field in an independent param class is OK: @RestSchema(schemaId = "testSchema") @RequestMapping(path = "test") public class TestRestService { @PostMapping(path = "post") public String post(@RequestBody TestBodyParam body) { return null == body ? "null" : body.toString(); } } // define param type in an independent class public class TestBodyParam { private InnerBody innerBody; public static class InnerBody { // fields omitted } // fields omitted } As described above, in some case, the inner class param type works well. If you think this feature should be provided, I'll create a JIRA issue to track it. Yours sincerely Yao Haishi yhs0...@163.com
