调测springboot样例程序
在本地Windows环境中调测ClickHouse Springboot样例程序
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。在开发环境IntelliJ IDEA工程“clickhouse-rest-client-examples”中右键单击“ClickHouseApplication”，选择“Run ClickHouseApplication”运行应用程序工程。
操作步骤
- 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”。
图1 复制配置文件绝对路径
- 使用clickhouse-example.properties路径替换ClickHouseFunc.java中getProperties()方法中proPath的路径。
图2 ClickHouseFunc.java路径替换
查看调测结果
- ClickHouse springboot服务启动后，通过ClickHouse样例接口触发样例代码运行，在浏览器中输入需要执行具体操作的链接，如http://localhost:8080/clickhouse/executeQuery，返回结果：
ClickHouse springboot client runs normally.
- 通过ClickHouse日志获取应用运行情况，即日志文件：clickhouse-springboot-example.log。
运行clickhouse-springboot样例后，控制台显示部分运行结果如下：

在Linux环境中调测ClickHouse Springboot样例程序
ClickHouse springboot应用程序也支持在Linux环境中运行。在程序代码完成开发后，您可以上传Jar包至准备好的Linux运行环境中运行。
前提条件
Linux环境已安装JDK，版本号需要和IntelliJ IDEA导出Jar包使用的JDK版本一致，并设置好Java环境变量。
编译并运行程序
- 在IDEA中右侧单击“Maven”，展开“Lifecycle”，双击“package”，对当前工程进行打包。
- 使用root用户登录ClickHouse客户端节点，创建运行目录，例如“/opt/test”，在IDEA的“target”目录下获取带有“-with-dependencies”的jar包，并将jar包和idea中conf文件夹一同上传到“/opt/test”目录，如：
- 执行如下命令，配置环境变量并运行jar包：
cd 客户端安装路径
source bigdata_env
cd /opt/test
java -jar clickhouse-examples-1.0-SNAPSHOT-jar-with-dependencies.jar
显示结果如下：
- 调用ClickHouse的SpringBoot样例接口触发样例代码运行：
