Question

我正在制作一个Web项目，在本地完成后，我将其上传到服务器（centos7），但是当我转到主页时，日志将返回此错误。

奇怪的是，在我的笔记本电脑（Mac）上一切正常，但是当我通过服务器打开它时。 spring-boot日志告诉您找不到两个表。所有其他表似乎还可以。和主页确实从db获取数据。从现在起，我无法从Internet找到解决方案。我检查了服务器中的db，两个表都存在。（它们内部目前没有数据。）

@Entity
@Table(name = "orderItem")
@JsonIgnoreProperties({ "handler","hibernateLazyInitializer" })
public class OrderItem {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id")
private int id;

@ManyToOne
@JoinColumn(name="pid")

private Product product;

@ManyToOne
@JoinColumn(name="oid")
private Order order;

@OneToOne
@JoinColumn(name="uid")
private User user;


@OneToOne
@JoinColumn(name="sid")
private User seller;


public List<Request> getRequests() {
    return requests;
}

public void setRequests(List<Request> requests) {
    this.requests = requests;
}

@Transient
private List<Request> requests;

private int status;
private int price;
private Date createDate;
private int way;
private int number;

我在此错误上浪费了很多时间。

表名在MySQL中区分大小写。在实体类中将表名称更正为“ orderitem”，然后重试。与“聊天”表相同。
