### Spring Boot（三）之jar包改成war包模式 ###

#### 修改pom.xml文件 ####

1.  将jar包改成war包

<packaging>war</packaging>

1.  添加Spring Boot 的tomcat依赖

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>

1.  添加Servlet依赖，只在编译时有效

<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>
        <scope>provided</scope>
    </dependency>

1.  实现SpringBootServletInitializer，重写configure()方法

@SpringBootApplication
    @MapperScan("com.zhang.springbootmybatisdemo.dao")
    public class SpringbootMybatisDemoApplication extends SpringBootServletInitializer { 
    
        public static void main(String[] args) {
            SpringApplication.run(SpringbootMybatisDemoApplication.class, args);
        }
    
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
            return application.sources(SpringbootMybatisDemoApplication.class);
        }
    }

1.  编译打包

mvn clean package

可以在target目录下看到打出war包了。

#### 修改war包和target目录下项目名 ####

在中使用，指定最后项目名称和war名称

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

再次打包：`mvn clean package`
