Spring Boot之jar包改成war包模式

修改pom.xml文件

將jar包改成war包

<!--<packaging>jar</packaging>-->

<packaging>war</packaging>

添加Spring Boot 的tomcat依賴

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

添加Servlet依賴，只在編譯時有效

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

實現SpringBootServletInitializer，重寫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);
    }

編譯打包
mvn clean package

可以在target目錄下看到打出war包了。

修改war包和target目錄下項目名

在中使用，指定最後項目名稱和war名稱

<build>
    <!-- 最後項目名稱，war包名稱 -->
    <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
