我對此很陌生。你能告訴我如何設置在 Docker 中運行的調試 Java 程序嗎？該項目是在 Maven 的幫助下構建的，之后使用 Docker*.war來運行程序。據我了解，必須遠程推送 IntelliJ 進行調試。docker-compose.yml ：# myapp (Wildfly + Keycloak + myapp) myapp-myapp: image: myapp/wildfly-myapp:wf11 container_name: myapp-myapp depends_on: - myapp-postgres - myapp-mailhog environment: TZ : Europe/Paris KEYCLOAK_URL: http://localhost:8080/auth WILDFLY_PROXY_ADDRESS_FORWARDING: "true" JAVA_OPTS: DB_CONNEXION_URL: jdbc:postgresql://myapp-postgres:5432/myapp_db DB_CONNEXION_URL_DELIMITER: "|" DB_HOST: myapp-postgres DB_NAME: ${DB_NAME} DB_PASSWORD: ${DB_PASSWORD} DB_USER: ${DB_USER} KEYCLOAK_DB_CONNEXION_URL: jdbc:postgresql://myapp-postgres:5432/keycloak KEYCLOAK_DB_CONNEXION_URL_DELIMITER: "|" KEYCLOAK_DB_USER : keycloak KEYCLOAK_DB_PASSWORD : keycloak KEYCLOAK_DB_NAME : keycloak KEYCLOAK_DB_HOST: postgres APP_CLUSTER: "false" JGROUPS_EXTERNAL_ADDRESS: 10.178.27.30 JGROUPS_TCP_EXTERNAL_PORT: 7600 JGROUPS_TCP_BIND_PORT: 7600 JGROUPS_DEFAULT_STACK: tcpping JGROUPS_INITIAL_HOSTS: "10.178.27.30[7600]" WILDFLY_CLUSTER_PASSWORD: WILDFLY_NODE_NAME: myapp-master SMTP_HOST: myapp-mailhog SMTP_PORT: 1025 SMTP_FROM: ${SMTP_FROM} SMTP_USERNAME: "" SMTP_PASSWORD: "" myapp_LOG_LEVEL: "ALL" myapp_DEBUG_LEVEL: "ALL" volumes: - ./myapp/data:/opt/jboss/myappdata - ./myapp/logs:/opt/jboss/wildfly/standalone/log - ./myapp/deployments:/opt/jboss/wildfly/standalone/deployments - ./myapp/configuration/myapp-admin.properties:/opt/jboss/wildfly/standalone/configuration/myapp-admin.properties - ${ST_SRC}:/opt/jboss/myappdata/${PROVIDER_CODE}/frontend/st - ${CC_SRC}:/opt/jboss/myappdata/${PROVIDER_CODE}/frontend/cc - ${SC_SRC}:/opt/jboss/myappdata/${PROVIDER_CODE}/frontend/sc ports: - "8080:8080" - "7600:7600"

您可以使用以下 JVM-Argument 啟用遠程調試
-agentlib:jdwp=transport=dt_socket,server=y,address=8000,suspend=n
然后你可以附加 Intellij 調試器Run->Attach to process 你的應用程序應該有指定的端口（在這種情況下是 8000）
請參閱此處了解更多信息
對于此示例（Docker-Compose with Wildfly）
environment:
...
JAVA_OPTS: -agentlib:jdwp=transport=dt_socket,server=y,address=8000,suspend=n
...
ports:
- "8000:8000"
...
一般來說

要在 Docker 中使用，您還必須公開端口
EXPOSE 8000
ENTRYPOINT ["java", "-jar", "-agentlib:jdwp=transport=dt_socket,server=y,address=8000,suspend=n", "/path/to/my/java.jar"]
進而
docker run -p 8000:8000 <image>
IntelliJ（從 2019.1 開始）
這個過程現在可以由 IntelliJ 自動完成 https://blog.jetbrains.com/idea/2019/04/debug-your-java-applications-in-docker-using-intellij-idea/
