我正在使用 Spring boot 和 Hibernate 以及 Tomcat8 开发一个 Web 应用程序。

这是我唯一的实体类:

    package blablabla.server.entity;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;


@Entity
@Table(name="restaurant")
public class Restaurant{

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    public Restaurant() {}

    public int getId() {
        return id;
    }

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

我知道有很多问题都存在同样的错误。但对我的情况没有任何作用。

我的 getter/setter 没有拼写错误。我的实体上已经有一个无参构造函数。javassist-3.22.0-GA.jar 在我的 blabla.war 上

注意:这是一个 Java8 Web 应用程序。在我的unix系统上安装了jdk11。我已经尝试将jdk版本更改为8，但错误仍然存在。

我能做什么？

PS:这是我的 pom.xml

最佳答案

已解决。

Java11 是问题所在。正如我所说，我已将 jkd 版本从 11 更改为 8，但我的 tomcat 实例仍然指向 Java11。
