In recent years, Spring boot is the favorite technology framework of many Java developers. Here, we have a very simple standard Spring boot project called heishan, as follows.

Here is the content of the file pom.xml presented by the Linux command cat.
lwk@qwfys:~/Public/project/default/heishan$ cat src/main/java/com/qwfys/sample/heishan/HeishanApplication.java
package com.qwfys.sample.heishan;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class HeishanApplication {
public static void main(String[] args) {
SpringApplication.run(HeishanApplication.class, args);}}
lwk@qwfys:~/Public/project/default/heishan$ cat src/main/resources/application.properties lwk@qwfys:~/Public/project/default/heishan$
Normally, we can start the project by executing the command mvn spring-boot:run in the command line terminal. Is there a way for our customers to run the project without worrying about how to configure the environment? In fact, yes, we can use maven wrapper.
Next, I will use maven wrapper to show you how to run it.

Is it convenient to do so? Friends, what do you think?
