Question

我正在尝试在云代工厂上启动一个jetty runner应用程序。代码是

https://github.com/simbo1905/ZkToDo2

可以使用

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

所以我用

创建了一个postgresql

vmc create-service postgresql pgsql

压缩jar并将其打成拉链然后尝试部署到云代工厂时它会给我一个内存不足的错误。是什么赋予了？

是什么给出了？

Answer 1

Cloud Foundry将所选内存分配的-Xmx设置添加到JAVA_OPTS env变量中，您需要将其包含在start命令中（java $ JAVA_OPTS -Djetty ....）。或者，您可以在启动命令中包含-Xmx。

Answer 2

我确实部署了ZkToDo2 on cloudfoundry和一个码头跑者。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配置的postgresql数据库的连接参数匹配，我不得不对该应用程序进行一些小的修改。

这是pull request。
