如何在spring @RestController中验证@QuerydslPredicate？

import com.querydsl.core.types.Predicate;
import org.springframework.core.MethodParameter;
import org.springframework.stereotype.Component;
import org.springframework.validation.BeanPropertyBindingResult;
import org.springframework.validation.Errors;
import org.springframework.validation.ValidationUtils;
import org.springframework.validation.Validator;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.method.support.HandlerMethodArgumentResolver;
import org.springframework.web.method.support.ModelAndViewContainer;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter;

import javax.servlet.http.HttpServletRequest;
import javax.validation.Valid;
import java.util.List;

@Component
public class QuerydslPredicateValidator implements HandlerMethodArgumentResolver {

    private final Validator validator;

    public QuerydslPredicateValidator() {
        this.validator = new QuerydslPredicateValidatorImpl();
    }

    @Override
    public boolean supportsParameter(MethodParameter parameter) {
        return Predicate.class.isAssignableFrom(parameter.getParameterType()) &&
                parameter.hasParameterAnnotation(QuerydslPredicate.class);
    }

    @Override
    public Object resolveArgument(MethodParameter parameter, ModelAndViewContainer mavContainer,
                                  HttpServletRequest request, RequestMappingHandlerAdapter adapter) throws Exception {
        String[] parameterValues = request.getParameterValues(parameter.getParameterName());
        if (parameterValues != null && parameterValues.length > 0) {
            String parameterValue = parameterValues[0];
            Predicate predicate = // 使用Querydsl的API构建查询条件
            Errors errors = new BeanPropertyBindingResult(predicate, "predicate");
            ValidationUtils.invokeValidator(validator, predicate, errors);
            if (errors.hasErrors()) {
                throw new MethodArgumentNotValidException(parameter, errors);
            }
            return predicate;
        }
        return null;
    }

    @RestController
    public class MyController {

        @GetMapping("/data")
        public List<Data> getData(@Valid @QuerydslPredicate Predicate predicate) {
            // 处理查询逻辑
        }
    }
}
