I tried to call the HTTP interface in the JVM without passing the VO object, which is perfect. However, this exception occurs when the HTTP interface is called in the same way after the native compilation.

Comment From: wilkinsona
It looks like there's some reflection metadata missing that prevents the constructors of xx.xx.xx.SysRoleQueryVo from being found. Such metadata should be generated automatically by Spring Framework due to its use as an argument of a @GetMapping method. We'll transfer this to the Framework team so that they can investigate.
Comment From: sdeleuze
A known limitation of ControllerMappingReflectiveProcessor is that it only registers reflection hint for parameters annotated with @RequestBody, @ModelAttribute and @RequestPart, I have refined the Javadoc as part of #29938 accordingly. So if you are relying on the ModelAttributeMethodProcessor initialized with annotationNotRequired=true to have implicit handling of the SysRoleQueryVo parameter, the reflection hint inference won't be performed on native because the "signal" is too complex to infer.
Before discussing what we should do, could you please confirm this is your use case, and that it works with @ModelAttribute?

yes, this is my user case. I tried to use @RequestParam(required=false), but it didn't work.
In fact, my requirement is only to return null values when there is no need to pass VO classes. However, the code that can run under the JVM environment cannot run under the native platform.
Comment From: sdeleuze
Could you please let me know if it works with @ModelAttribute roleQueryVo: SysRoleQueryVo??

It seems that adding @ModelAttribute has a certain effect, but I still need to go through more tests!

Has this problem been resolved. I also encountered this problem today.
