시스템 속성 설정

시스템 속성 설정

---

나는이 지시를 따르려고합니다.

"gate.home 시스템 속성은 게이트 설치 디렉토리로 설정되어야합니다." (http://gate.ac.uk/wiki/code-repository/)

어떻게해야합니까?

또한 EmbeddedAnnie의 예제 코드를 실행하려고하면 다음과 같은 오류가 발생합니다. (관련 여부를 모르겠습니다).

Initialising GATE...
GATE home system property ("gate.home") not set.

If this is not correct please set it manually using the -Dgate.home option in yo

몇 가지 방법을 통해이 작업을 수행 할 수 있습니다.

하나는 애플리케이션을 실행할 때 플래그를 전달할 수 있다는 것입니다.

java -Dgate.home="http://gate.ac.uk/wiki/code-repository" your_application

또는이 속성 집합이 필요한 코드 전에 코드에서 프로그래밍 방식으로 설정하십시오. Java Properties는 System광범위한 구성을 위한 객체를 유지 합니다.

Properties props = System.getProperties();
props.setProperty("gate.home", "http://gate.ac.uk/wiki/code-repository");

---

System.setProperty("gate.home", "/some/directory");

자세한 내용은 다음을 참조하십시오.

• 시스템 등록 튜토리얼 .
• 대한 클래스 문서 System.setProperty( String key , String value ).

---

System.setProperty("gate.home", "/some/directory"); 

그런 다음 나중에 호출하여 값을 검색 할 수 있습니다.

String value =  System.getProperty("gate.home");

---

For JBoss, in standalone.xml, put after .

<extensions>
</extensions>

<system-properties>
    <property name="my.project.dir" value="/home/francesco" />
</system-properties>

For eclipse:

You need the path of the plugins directory of your local GATE install. So if Gate is installed in "/home/user/GATE_Developer_8.1", the code looks like this:

System.setProperty("gate.home", "/home/user/GATE_Developer_8.1/plugins");

You don't have to set gate.home from the command line. You can set it in your application, as long as you set it BEFORE you call Gate.init().
