Idea打包springboot项目为war

1、更改打包类型为war

<packaging>war</packaging>

2、排除tomact

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>2.7.0</version>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                </exclusion>
            </exclusions>
        </dependency>


          <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.1.0</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat</groupId>
            <artifactId>tomcat-servlet-api</artifactId>
            <version>8.0.36</version>
            <scope>provided</scope>
        </dependency>

3、更改打包后的名字、新增maven-war-plugin插件

    <build>
        <finalName>demo2</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.0.0</version>
            </plugin>
        </plugins>
    </build>

4、新增maven打包配置

点击Idea右上角run左边的环境
选择Edit Configurations
打开Run/Debug Configurations窗口
点击左上角+，新增maven，运行命令填写如下

clean compile package -Dmaven.test.skip=true

5点击运行，即可看到打包

D:\BaiduNetdiskDownload\a1\demo2\target\demo2.war
