Spring WebDataBinder getTarget() get 请求返回null

I am a beginner and learning springboot

springboot 3.2+ WebDataBinder getTarget() get request returns null

@InitBinder public final void dataBinder(WebDataBinder binder) { if (binder.getTarget() instanceof BaseCondition baseCondition) { binder.addValidators(baseCondition); } }

binder.getTarget() == null; Version 3.1.12 is available

public interface BaseCondition extends Validator {

}

public class LoginCondition implements BaseCondition {

}

binder.getTarget() will be null if your controller method has a simple type parameter.

binder.getTarget() will be null if your controller method has a simple type parameter.

public String test111(@Valid LoginCondition condition) {
    System.out.println("condition = " + condition);
    return "test";
}

我想实现统一参数验证，目前这种方式 get 请求binder.getTarget() == null, post 是ok的
