Spring Boot 打 war 包的步骤

## Spring Boot 打 war 包的步骤

1. 添加 spring-boot-start-tomcat 的 provided 依赖

```

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-tomcat</artifactId>

<scope>provided</scope>

</dependency>

```

2. 添加 maven-war-plugin 插件

```

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-war-plugin</artifactId>

<configuration>

<failOnMissingWebXml>false</failOnMissingWebXml>

</configuration>

</plugin>

```

3. 继承 SpringBootServletInitializer, 重写 config 方法

```

@Override

protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {

return builder.sources(MainApplication.class);

}

```
