Java org.hibernate.MappingException:未知实体：me.News

好的，这个问题与同一标题的问题不同，我尝试了很多解决方案，但我解决不了

实体：

package me;

import javax.persistence.*;

@Entity
@Table(name = "news_inf")
public class News {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;
    private String title;
    private String content;

    public void setId(Integer id) {
       this.id = id;
    }

    public Integer getId() {
        return this.id;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getTitle() {
        return this.title;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public String getContent() {
        return this.content;
    }
}

测试呢

package me;

import org.hibernate.*;
import org.hibernate.cfg.*;
import org.hibernate.service.*;
import org.hibernate.boot.registry.*;

public class Test3 {
    public static void main(String[] args) throws Exception {
        Configuration conf = new Configuration().configure();
        ServiceRegistry serviceRegistry = new  StandardServiceRegistryBuilder()
            .applySettings(conf.getProperties())
            .build();
        SessionFactory sf = conf.buildSessionFactory(serviceRegistry);
        Session sess = sf.openSession();
        Transaction tx = sess.beginTransaction();
        News n = new News();
        n.setTitle("1234");
        n.setContent("1234");
        sess.save(n);
        tx.commit();
        sess.close();
        sf.close();
    }
}

我不知道为什么我错了？我需要帮助，谢谢

也许还要添加xml您确定您的测试正在使用xml吗？是的，控制台显示了名称和密码的消息
