1,idea maven打包按钮介绍

 

 

<properties>
    <java.version>2.5.2</java.version>

    <!--跳过测试类打包-->
    <skipTests>true</skipTests>
    
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <spring-boot.version>2.5.2</spring-boot.version>

</parent>

6、<dependency>标签

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

package com.jt.springboot_demo1;

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class SpringbootDemo1ApplicationTests {

    @Test
    void contextLoads() {
    }

}

8、<build>标签

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
