maven에 의존성 추가 하고 나서 다음과 같은 에러 발생.

추가한 라인

 

<!-- Tika -->
  <dependency>
   <groupId>org.apache.tika</groupId>
      <artifactId>tika-core</artifactId>
      <version>1.26</version>
  </dependency>
  <dependency>
      <groupId>org.apache.tika</groupId>
      <artifactId>tika-parsers</artifactId>
      <version>1.26</version>
    </dependency>

tika 버전을 2.0.0으로 할 때는 에러가 없었으나, 버전 변경 후 발생

해결 과정

서치해보니 tomcat + jdk 버전 오류라고 함

 

이클립스 jdk 버전 확인하는 법

> 프로젝트 우클릭 - Properties - Java Compiler - JDK Compliance 에 표시되어있음

 

다음 조합을 맞춰주어야 정상적으로 구동된다고 함

• Tomcat 9.0.x : 9.0.0.M18 이후
• Tomcat 8.5.x : 8.5.12 이상
• Tomcat 8.0.x : 8.0.42 이상
• Tomcat 7.0.x : 7.0.76 이상

내가 해결한 방법

현재 내 jdk 버전 : 1.8

tomcat 버전 : 8.0.36

톰캣 버전을 9.0.44로 변경하니 정상적으로 구동됨
