在本地Windows环境中调测ClickHouse应用（MRS 3.3.0及之后版本）

编译并运行程序

在程序代码完成开发后，您可以在Windows环境中运行应用。本地和集群业务平面网络互通时，您可以直接在本地进行调测。

操作步骤

  1. 单击IDEA右边Maven窗口的“Reload All Maven Projects”，进行maven项目依赖import。

    图1 reload projects

  2. 在IDEA界面复制clickhouse-example.properties路径。右键clickhouse-example.properties文件，单击“Copy Path/Reference > Absolute Path”。

    事务样例工程无需执行此步骤。

    图2 复制配置文件绝对路径

  3. 使用clickhouse-example.properties路径替换Demo.java中getProperties()方法中proPath的路径。

    图3 Demo.java路径替换

  4. 使用clickhouse-example.properties路径替换ClickhouseJDBCHaDemo.java中initConnection()方法中proPath的路径。

    事务样例工程无需执行此步骤。

    图4 ClickhouseJDBCHaDemo.java路径替换

  5. 编译程序。

    • 选择“Maven > clickhouse-examples > Lifecycle > clean”，双击“clean”运行maven的clean命令。
    • 选择“Maven > clickhouse-examples > Lifecycle > compile”，双击“compile”运行maven的compile命令。
    图5 Maven的clean和compile

  6. 单击“Run 'Demo.main()'”运行应用程序工程。

    图6 运行程序

查看调测结果

ClickHouse应用程序运行完成后，可通过以下方式查看程序运行情况：

  • 通过运行结果查看程序运行情况。
  • 通过ClickHouse日志获取应用运行情况，即“logs”目录下的日志文件：clickhouse-example.log。

运行clickhouse-examples的完整样例后，控制台显示部分运行结果如下：
