修改pom.xml文件

添加Tomcat依赖包

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

把pakaging有jar改成war

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

重写SpringBootServletInitializer的configure方法

与Application类在一个目录下

public class ServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
}

也可以直接修改启动类

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


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

然后打包

注：有时候测试方法法出错或使用断言抛出异常会导致打成war包失败
解决方法为修改pom.xml文件

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration>
                    <testFailureIgnore>true</testFailureIgnore>
                </configuration>
            </plugin>
        </plugins>
</build>
