SpringBoot maven 打 war 部署Tomcat

pom.xml 添加一个依赖和插件

<build>
        <finalName>${project.artifactId}</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <configuration>
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                </configuration>
            </plugin>
        </plugins>
    </build>

启动文件需要 继承 SpringBootServletInitializer， 并重写 configure

@SpringBootApplication
public class MainApplication extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(MainApplication.class);
    }
}

切换到项目根目录，mvn clean package 打 war, 拷贝到 Tomcat webapps 下面 启动 Tomcat 。
