添加配置选项时
.set("jmx-manager-start", "true")
.set("jmx-manager", "true")
我发现了这个异常

【问题讨论】：
-
如果您通过定位器连接，并且 jmx-manager 尚不存在，则定位器会启动一个。 gemfire.docs.pivotal.io/geode/tools_modules/gfsh/command-pages/…
-
使用 -Dgemfire.jmx-manager=true -Dgemfire.jmx-manager-start=true 也会给来自stackoverflow.com/questions/30880830/…的NPE异常
-
你是如何启动定位器的？默认情况下，定位器应该启动 JMX 管理器。
-
ServerLauncher serverLauncher = new ServerLauncher.Builder() .setMemberName(ID) .setServerPort(40404) .set("bind-address", priIp) .set("mcast-port", "0" ) .set("start-locator", priIp+"[11001]") .set("cache-xml-file", "server-cache.xml")
-
所以通过在服务器配置中设置“start-locator”
