SpringBoot项目打包成war包

重要步骤

1. springBoot启动类需继承SpringBootServletInitializer类并覆盖configure方法。

@SpringBootApplication
public class SpringBoot08Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        //参数为SpringBoot启动类
        return builder.sources(SpringBoot08Application.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(SpringBoot08Application.class, args);

    }

}

2. 在pom.xml中添加

<packaging>war</packging>

3. 在pom.xml中配置springBoot打包插件（默认自动添加）

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>2.3.7.RELEASE</version>
</plugin>

4. 在pom.xml中配置将配置文件编译到类路径

<resources>
    <resource>
        <directory>src/main/webapp</directory>
        <targetPath>META-INF/resources</targetPath>
        <includes>
            <include>**/*.*</include>
        </includes>
    </resource>
    <resource>
        <directory>src/main/java</directory>
        <includes>
            <include>**/*.xml</include>
        </includes>
    </resource>
    <resource>
        <directory>src/main/resources</directory>
        <includes>
            <include>**/*.*</include>
        </includes>
    </resource>
</resources>

5. 在pom.xml的build标签下通过finalName指定打包war包的名字

<build>
    <finalName>war包的名字</finalName>
</build>
