Java 如何解决通过字段'；schedulerService'；？

我正在尝试将一个（添加oracle驱动程序）安装到openshift中（遵循了SCDF的Kubectl安装文档）。我修改了deployment.yaml以从git repo中提取我的这个自定义SCDF docker映像。现在，当我启动容器时，我得到以下错误

Dockerfile-将作为上面使用的自定义SCDF映像构建

FROM maven:3.5.2-jdk-8-alpine AS MAVEN_BUILD

COPY pom.xml /build/
COPY src /build/src/

WORKDIR /build/
RUN mvn package

那么我做错了什么或错过了什么？请给我一些建议

提前感谢。

您很可能缺少任务平台配置，这是k8s部署文件的一部分。当您使用自己的

应用程序.properties

文件时，我感觉您没有使用k8s配置文件。

由于某种原因，此自定义版本没有读取server-config.yaml。即使它在server-deployment.yaml中显示为配置映射之一。因此，我将kubenetes任务平台属性移动到CustomBuild SCDF Spring boot项目的application.properties。因此，我从这个项目中构建的docker图像也就是kubernetes属性。添加此选项后，server-deployment.yaml将能够获得k8平台属性，并且SCDF开始成功运行

我的application.properties当前如下所示

spring.application.name=CustomSCDF
spring.datasource.url=jdbc:oracle:thin:@datasource_url
spring.datasource.username=username
spring.datasource.password=Password
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

#properties moved from server-config.yaml
spring.cloud.dataflow.task.platform.kubernetes.accounts.default.image-pull-policy= always
spring.cloud.dataflow.task.platform.kubernetes.accounts.default.entry-point-style= exec
spring.cloud.dataflow.task.platform.kubernetes.accounts.default.limits.cpu=4

我认为只有定制的应用程序才会面临这个问题。但这需要更清楚。

可能是您使用的Oracle驱动程序与我们提供的Hibernate版本不兼容。如果你能分享捆绑SCDF自动配置的Spring Boot应用程序，我们可以看一看。下面是位置。您应该显示完整的服务器启动日志，这可能会告诉您更多。Janne在git repo中添加了完整的日志文件。您好，我在下面添加了我的答案。如果属性来自服务器配置，为什么您认为它们不会被读取？在尝试将服务器配置文件映射到部署时，我还看到了一些警告<代码>警告：配置映射scdf服务器包含的键不是有效的环境变量名称。只有具有有效名称的配置映射键才会添加为环境变量。但我使用了SCDF核心项目中的配置映射键。不过，我无法准确定位这一问题。但是，如果你认为我下面的答案是有效的，请让我知道我可以将其标记为答案并关闭此线程。Janne，我实际上尝试了两种选择。但似乎都没有起作用。一旦我从部署中添加了server-config.yaml并启动了容器，接下来我就删除并尝试了。两者产生相同的结果。我还在git repo中附加了server-config.yaml和server-deployment.yaml。
