我正在尝试在 Cloud Foundry 上启动一个 jetty runner 应用程序。代码是

https://github.com/simbo1905/ZkToDo2

可以在本地启动

java -Djetty.host=localhost -Djetty.port=8080 -DDATABASE_URL=jdbc:postgresql://postgres:postgres@localhost/postgres -jar jetty-runner-jmx.jar zktodo2.war

所以我创建了一个postgresql

vmc create-service postgresql pgsql

当将 jar 和 war 压缩成 zip 然后尝试部署到云代工厂时，它给了我一个内存不足的错误。是什么赋予了？ 

simbo$ vmc push zktodo2 --path=cf.zip

Cloud Foundry 将您选择的内存分配的 -Xmx 设置添加到 JAVA_OPTS 环境变量中，您需要将其包含在启动命令中 (java $JAVA_OPTS -Djetty....)。或者，您可以在启动命令中包含 -Xmx。

我确实使用jetty-runner在 cloudfoundry 上部署了 ZkToDo2 。这是我使用的启动命令：

java -Djava.io.tmpdir=. -Dorg.apache.jasper.compiler.disablejsr199=true -Xmx512M -jar jetty-runner-jmx.jar --port ${VCAP_APP_PORT} zktodo2.war

为了使 DATABASE_URL 与 cloudfoundry 提供的 postgresql 数据库的连接参数相匹配，我不得不对应用程序进行一些小的修改。

这是拉取请求。
