私は知っている、それは重複した質問ですが、問題は新しいです、重複した質問をマークしないでください。このプログラムはWindow 10で実行され、正常に実行されてデータベースが作成されますが、Debian 9で同じプログラムが実行されると例外がスローされます。その後、Googleでこの問題を確認しました。一部の人は、すべてのユーザークラスの状態設定メソッドと取得メソッドを作成すると言いました。セッターとゲッターメソッドを作成しましたが、同じ例外がスローされます。
ユーザークラス
@Entity
public class User {
@Id
private Long id;
private String firstName;
private String lastName;
private String professional;
private int age;
public User() {}
public User(Long id, String firstName, String lastName, String professional, int age) {
this.id = id;
this.firstName = firstName;
this.lastName = lastName;
this.professional = professional;
this.age = age;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getFirstName() {

問題はJdk 11とjavassistにあります。
これをpom.xmlに追加します。
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.23.1-GA</version>
</dependency>
から取得した情報: here
Java 8からJava 11に移行するときは、多くの機能がそのままでは機能しないことに注意する必要があります。
Java.version = 1.8が定義されています
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<Java.version>1.8</Java.version>
</properties>
OpenJDK 11(Travis-CIのデフォルト)を使用すると、この例外が発生する場合があります。
.travis.yml
でJDKバージョンを8に変更してみてください:
jdk:
- openjdk8
