[Spring] JPA (Hibernate) - Error (creating bean with name 'entityManagerFactory')

JDK를 openjdk11로 변경했더니 startup할 때 오류가 발생

ERROR o.s.boot.SpringApplication - Application run failed

원인

• JPA(Hibernate)라는 것은 결국 BCI방식으로 class load시점에 entity와 JPA Interface를 이용하여 SQL문을 자동 생성하여 삽입시켜주는 역할
• 로그를 보면 org.hibernate.persister.entity.SingleTableEntityPersister의 생성자에서 그 역할을 하는듯 하다.
• 그런데 openjdk11에서는 javaassist가 removed 되었는지 entityManagerFactory 빈을 생성할 때
  • at javassist.util.proxy.SecurityActions.setAccessible(SecurityActions.java:103)에서 NullPointerException이 발생한다.

해결

• pom.xml에 javassist에 대한 dependency를 추가해주면 된다.

  <dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.23.1-GA</version>
