SpringBoot

1 将SpringBoot打成war包

（1）添加Tomcat依赖，去除Tomcat

<!-- 设置tomcat在打包时去除-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

（2）将jar包修改为war包

<packaging>war</packaging>

（3）添加Servelt依赖

这一步我并没有使用，也可以

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

（4）修改启动类

@SpringBootApplication
public class DemoApplication  extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(DemoApplication.class);
    }

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

（5）修改打包名称

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

用finalName定义最后输出的war包的名称。
