것은 제시해주십시오 ** mvn 의존성의 출력 : tree **. 질문으로 편집하십시오. 읽을 수 없으므로 주석에 게시하지 마십시오. – Gimby

@ 김비, 시간 내 주셔서 감사합니다. 그것은 의존성 충돌 때문이었습니다. 이전에 제외 항목을 추가했지만 범위가 제공되었고 제외가 작동하지 않았습니다. 범위를 제거하면 예외가 적용됩니다. –

이상한 점은 범위가 제외에 영향을 미치지 않아야한다는 것입니다. – Gimby

이전에는 충돌 라이브러리의 존재로 인한 비슷한 문제가있었습니다.

종속성 트리에 org.javassist이있는 pom.xml의 종속성을 찾아서 각각의 종속성 트리에서 명시 적으로 제외 시키십시오. 가장 일반적인 사람은 hibernate-core, hibernate-entitymanager 및 spring-data-jpa 될 것이라고 볼 수 있습니다 :

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-entitymanager</artifactId> 
    <version>${my.hibernate.version}</version> 
    <exclusions> 
     <exclusion> 
      <groupId>org.javassist</groupId> 
      <artifactId>javassist</artifactId> 
     </exclusion> 
    </exclusions> 
</dependency>

프로젝트에서 해당 라이브러리의 하나의 소스가되도록

그리고 단순히 수동으로 종속성을 추가 :

<dependency> 
    <groupId>org.javassist</groupId> 
    <artifactId>javassist</artifactId> 
    <version>3.21.0-GA</version> 
</dependency>
