如何解决我的config.yaml中意外的':'错误？

Question

我不知道我的config.yaml有什么问题

我按照官方网站上的示例配置了我的config.yaml， 和当我完成配置时。我运行命令：

java -javaagent:./jmx_prometheus_javaagent-0.12.0.jar=8980:config.yaml -jar /usr/local/tomcat/apache-activemq/apache-activemq-5.8.0_56/bin/activemq.jar

但是我收到有关我的config.yaml的错误

这是我的配置文件

[root@sz-7-centos162 test]# cat config.yaml 
{
startDelaySeconds: 0,
username: admin,
password: admin,
jmxUrl: service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi,
ssl: false,
lowercaseOutputName: false,
lowercaseOutputLabelNames: false
}

以下是错误日志：

Answer 1

将 URL 括在引号中，例如jmxUrl: "service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi"

Answer 2

您需要将值括在引号中，如下所示：

jmxUrl: "service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi",
