Graphviz를 사용하여 Java에서 그래프 조작

Question

Graphviz에서 java를 사용하여 gv_java - graph 조작을 사용하려고합니다. 필요한 경우 java.Installed graphviz에 SWIG Type 파일이 포함 된 java 패키지를 다운로드했습니다.

깨끗한 솔루션을 위해 graphviz에서 제공하는 JNI를 사용해 보았습니다. 여기에 내 테스트 코드가 있습니다.

시스템은 라이브러리를로드 할 수 있습니다,하지만 난 네이티브 메소드를 호출 할 때 나는 어떤 메시지없이 메서드 호출의 라인에 UnsatisfiedLinkError를 얻을.

나는 틀린 일을하고있다. 나는 리눅스 머신에 graphviz를 설치했다. 라이브러리와 모든 클래스가 위치에있다.

Answer 1

설치를 점검하고 모든 것이 적절하므로 내 java 파일에 문제가 있다고 판단했습니다.

Graphviz에 대해 모든 Java 메소드 이름이 SWIG에 의해 생성되었으므로 JNI 메소드를 사용하는 동안 명명 규칙에 대한 다양한 게시물을 읽었습니다. 다음으로 패키지 구조를 확인했습니다.

위의 코드에서 처음에는 내 org.graphviz (제공 한대로) 내 패키지 이름에 GraphViz 원시 메소드가 모두있었습니다.

나는 그들을 각각의 패키지로 옮겼고 매력처럼 작동했다!
