如何在java反射中隐藏子模型类属性名称

public class SubModel {
    private String sensitiveInfo;

    public String getSensitiveInfo() {
        return sensitiveInfo;
    }

    public void setSensitiveInfo(String sensitiveInfo) {
        this.sensitiveInfo = sensitiveInfo;
    }
}

import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;

@Retention(RetentionPolicy.RUNTIME)
public @interface Hidden {
}

public class SubModel {
    @Hidden
    private String sensitiveInfo;

    public String getSensitiveInfo() {
        return sensitiveInfo;
    }

    public void setSensitiveInfo(String sensitiveInfo) {
        this.sensitiveInfo = sensitiveInfo;
    }
}

import java.lang.reflect.Field;

public class ReflectionUtil {
    public static void printFields(Object obj) throws IllegalAccessException {
        for (Field field : obj.getClass().getDeclaredFields()) {
            if (!field.isAnnotationPresent(Hidden.class)) {
                field.setAccessible(true);
                System.out.println(field.getName() + ": " + field.get(obj));
            }
        }
    }
}

public class SubModelProxy {
    private SubModel subModel;

    public SubModelProxy(SubModel subModel) {
        this.subModel = subModel;
    }

    public String getSafeInfo() {
        // 只返回安全的信息
        return "Safe Info";
    }
}
