I found the reason, the spring plugin remove the annotation when enhance the method, let me think and fix the issue

  cachedValue$enuaW9Jm$6e6svp1 = ProducerSchemaFactory.class.getMethod("getOrCreateProducerSchema", String.class, Class.class, Object.class);
        cachedValue$enuaW9Jm$u2pnf53 = ProducerSchemaFactory.class.getMethod("setSwaggerEnv", SwaggerEnvironment.class);
        cachedValue$enuaW9Jm$hf4k4j3 = AbstractSchemaFactory.class.getMethod("setSchemaLoader", SchemaLoader.class);
