在实现org.springframework.validation.Validator时随时访问标头

import org.springframework.validation.Errors;
import org.springframework.validation.Validator;
import javax.servlet.http.HttpServletRequest;

public class CustomValidator implements Validator {

    @Override
    public boolean supports(Class<?> clazz) {
        // 判断是否支持验证特定的对象类型
        return YourObject.class.isAssignableFrom(clazz);
    }

    @Override
    public void validate(Object target, Errors errors) {
        HttpServletRequest request = (HttpServletRequest) target;
        
        // 获取请求的标头信息
        String headerValue = request.getHeader("HeaderName");
        
        // 进行标头信息的处理和验证
        // ...
    }
}
