springBoot运行方式，打包部署_spring-boot-maven-plugin:2.1.0.release:repackage

SpringBoot总结

运行方式

直接在IDE中运行入口类

@SpringBootApplication
public class Springboot01Application {

    public static void main(String[] args) {
        SpringApplication.run(Springboot01Application.class, args);
    }

}

通过spring-boot-maven-plugin 打成可执行jar包，通过java -jar运行

打包插件(通过start.spring.io创建的工程默认就有)

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

可通过Terminal利用命令mvn clean package 来执行，可直接java -jar，或将jar包放在外部tomcat里运行。

通过mvn spring-boot:run运行

打包部署

jar包

(SpringBoot官方建议通过SpringBoot提供的打包插件将项目打包成一个可执行的jar包pom.xml文件中没写packaging标签的话默认是jar包(在这个jar包里面已经内置了Tomcat，可以直接当一个web跑)，方便部署和管理。)

如上述的打包插件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <!-- ... -->

    <build>
        <plugins>

                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                </configuration>
            </plugin>
        </plugins>
    </build>

通过mvn clean package

​ java -jar 文件名.jar

D:\JAVA\IdeaProjects\springboot-01>dir
D:\JAVA\IdeaProjects\springboot-01> cd target

D:\JAVA\IdeaProjects\springboot-01\target>dir

D:\JAVA\IdeaProjects\springboot-01\target>java -jar springboot-01-0.0.1-SNAPSHOT.jar

在外部tomcat中运行，找到本机tomcat安装路径，bin目录下找到startup.bat，开启，运行后到浏览器里打开项目注意端口号后加项目名，访问页面。最后，shutdown.bat关闭tomcat服务器。

直接按照电脑系统中的路径找到jar包，或用命令行窗口执行命令，开启tomcat与上述的步骤一样。

注意， 如果你使用了src/main/webapp目录，打成jar包会忽略掉该目录下的所有文件，这种情况下只能选择打war包的方式

war包

1. 修改pom.xml文件
