本文介绍了Spring Boot 部署jar和war两种方式的区别，分享给大家，具体如下：
1、 packaging的方式不同，一种设置成jar一种是war
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>cn.vcyber.www</groupId> <artifactId>vcyber-api</artifactId> <!--这个地方有所区别 --> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name>vcyber-api</name> <url>http://maven.apache.org</url>
2、 继承的方式不同
Application.java需要继承SpringBootServletInitializer，而jar包不需要。
下面是war继承的方式：
@SpringBootApplication
@RestController
public class Application extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(Application.class,args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
}
3、spring boot内置tomcat
springboot内置tomcat容器，默认tomcat8的版本，war包部署时，需要在pom文件中有关跟tomcat有关系的jar包scope都设置成provided。
去掉spring boot内置的tomcat代码：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<artifactId>log4j-over-slf4j</artifactId>
<groupId>org.slf4j</groupId>
</exclusion>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
