如何在批注处理器上获取Java类的声明字段？

import javax.annotation.processing.AbstractProcessor;
import javax.annotation.processing.RoundEnvironment;
import javax.annotation.processing.SupportedAnnotationTypes;
import javax.lang.model.element.Element;
import javax.lang.model.element.ElementKind;
import javax.lang.model.element.TypeElement;
import java.lang.reflect.Field;
import java.util.Set;

@SupportedAnnotationTypes("YourAnnotation")
public class YourProcessor extends AbstractProcessor {

    @Override
    public boolean process(Set<? extends TypeElement> annotations, RoundEnvironment roundEnv) {
        for (Element element : roundEnv.getElementsAnnotatedWith(YourAnnotation.class)) {
            if (element.getKind() == ElementKind.CLASS) {
                TypeElement typeElement = (TypeElement) element;
                Class<?> clazz;
                try {
                    clazz = Class.forName(typeElement.getQualifiedName().toString());
                    Field[] fields = clazz.getDeclaredFields();
                    // 处理类的声明字段
                    for (Field field : fields) {
                        // 获取字段的名称、类型等信息
                        String fieldName = field.getName();
                        Class<?> fieldType = field.getType();
                        // 其他处理逻辑...
                    }
                } catch (ClassNotFoundException e) {
                    e.printStackTrace();
                }
            }
        }
        return true;
    }
}
