rocketmq-Namesrv理解1

Namesrv配置类

一个是mqnamesrv的基本配置，一个是提供服务的netty的配置

对应的类：NamesrvConfig  和 NettyServerConfig

// namesrv配置类
public class NamesrvConfig {

    // 日志 归类 名称：RocketmqNamesrv

        System.out.println(System.getProperty("user.home") + File.separator + "namesrv" + File.separator + "kvConfig.json");
        System.out.println(System.getProperty("user.home") + File.separator + "namesrv" + File.separator + "namesrv.properties");
    }

    // rocketmq 主目录 可以通过 -Drocketmq.home.dir=path 或通过设置环境变量 ROCKETMQ_HOME 来配置RocketMQ的主目录
    private String rocketmqHome = System.getProperty(MixAll.ROCKETMQ_HOME_PROPERTY, System.getenv(MixAll.ROCKETMQ_HOME_ENV));
    // NameServer 存储KV配置属性的持久化路径
    private String kvConfigPath = System.getProperty("user.home") + File.separator + "namesrv" + File.separator + "kvConfig.json";
    // NameServer 默认配置文件路经
    private String configStorePath = System.getProperty("user.home") + File.separator + "namesrv" + File.separator + "namesrv.properties";

    }

    public void setRocketmqHome(String rocketmqHome) {

    }

    public void setProductEnvName(String productEnvName) {

    }
