[java] “PKIX 경로 구축 실패”및“요청한 대상에 대한 유효한 인증 경로를 찾을 수 없습니다”

나는 공식 인증서와 달리 자동 생성 된 인증서를 사용하여 수정하는 데 많은 시간이 걸리는이 문제를 우연히 발견했습니다. 공식 인증서와 달리 상당히 까다 롭고 Java는 그렇게 많이 좋아하지 않습니다.

다음 링크를 확인하십시오. Java 인증서 문제 해결

기본적으로 서버에서 Java Home 인증서로 인증서를 추가해야합니다.

1. 인증서 생성 또는 가져 오기 및 Servers.xml에서 인증서를 사용하도록 Tomcat 구성
2. 클래스의 Java 소스 코드를 다운로드하여 InstallCert서버가 실행되는 동안 실행하여 다음 인수를 제공하십시오 server[:port]. 원래 비밀번호가 Java 인증서 ( “changeit”)에 대해 작동하므로 비밀번호가 필요하지 않습니다.
3. 본 프로그램은 서버에 연결되며 Java는 예외를 처리하며, 서버가 제공 한 인증서를 분석 jssecerts하고 프로그램을 실행 한 디렉토리 내에 파일 을 작성할 수 있도록합니다 (Eclipse에서 실행 된 경우 작업을 구성해야합니다) 에 디렉토리 Run -> Configurations).
4. 해당 파일을 수동으로 복사 $JAVA_HOME/jre/lib/security

이 단계를 수행 한 후에는 인증서와의 연결로 Java 내에서 더 이상 예외가 생성되지 않습니다.

다음 소스 코드는 중요하며 (Sun) Oracle 블로그에서 사라졌으며 제공된 링크에있는 유일한 페이지이므로 참조를 위해 답변에 첨부했습니다.
