通过JDBC语句执行DDL时出错

Question

我真的需要一些关于hibernate的帮助，我搜索所有问题，但它没有用。

我的问题很奇怪，至少我是这么认为的。在我的项目中，我想使用实体类，hibernate xml映射文件（* .hbm.xml）和hibernate配置文件（hibernate.cfg.xml）来创建mysql数据库中的表。奇怪的是我只能创建一个表，并且可以成功创建其他表。

好的，这些是我的项目代码，我认为可能会使用这些信息。

cart.java

import java.io.Serializable;
import java.util.HashMap;
import java.util.Map;

/**

public class Cart implements Serializable{

    private Integer id;
    private User user;
    private Map<Integer, Integer> shopItems = new HashMap<>();

    public Cart() {}

    public Cart(User user, Map<Integer, Integer> shopItems) {
        super();
        this.user = user;
        this.shopItems = shopItems;
    }

    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public User getUser() {
        return user;
    }
    public void setUser(User user) {
        this.user = user;
    }
    public Map<Integer, Integer> getShopItems() {
        return shopItems;
    }
    public void setShopItems(Map<Integer, Integer> shopItems) {
        this.shopItems = shopItems;
    }

    @Override
    public String toString() {
        return "Cart [id=" + id + ", user=" + user + ", shopItems=" + shopItems + "]";
    }

}
