SpringBoo项目打war包的多种方式

<!--默认为jar方式-->
<!--<packaging>jar</packaging>-->
<!--改为war方式-->
<packaging>war</packaging>

(本人使用第一种)

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

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>

public class ServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        //此处的Application.class为带有@SpringBootApplication注解的启动类
        return builder.sources(UserApplication.class);
    }
}

@SpringBootApplication
public class UserApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(UserApplication.class, args);
    }
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(UserApplication.class);
    }
}

mvn clean package -Dmaven.test.skip=true
