 这个example中，我们适配了java常见的连接池:
-* c3p0
-* dbcp
+* HikariCP（默认）
 * druid
-* HikariCP
+* dbcp
+* c3p0
 
 ### 说明
 ConnectionPoolDemo的程序逻辑：
 1. 创建到host的connection连接池
 2. 创建名称为pool_test的database，创建表超级weather，创建tableSize个子表
-3. 不断向所有子表进行插入。
+3. 总共插入totalNumber条数据。
 
 ### 如何运行这个例子：
+
 ```shell script
-# mvn exec:java -Dexec.mainClass="com.taosdata.demo.ConnectionPoolDemo" -Dexec.args="-host localhost"
+mvn clean package assembly:single
+java -jar target/connectionPools-1.0-SNAPSHOT-jar-with-dependencies.jar -host 127.0.0.1
 ```
 使用mvn运行ConnectionPoolDemo的main方法，可以指定参数
 ```shell script
 Usage: 
-mvn exec:java -Dexec.mainClass="com.taosdata.demo.ConnectionPoolDemo" -Dexec.args="<args>"

-### 如何停止程序：
-ConnectionPoolDemo不会自己停止，会一直执行插入，需要手动Ctrl+C运行。
-
 ### 日志
 使用log4j，将日志和错误分别输出到了debug.log和error.log中
