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>jar</packaging>-->
<packaging>war</packaging>

1. 添加Spring Boot 的tomcat依赖

<!--添加tomcat-->
<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>
    <!-- 最后项目名称，war包名称 -->
    <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
