打成war包，放到tomcat里运行
1 )pom.xml
<packaging>war</packaging>
排除内置tomcat
<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>
2）右键工程-maven-update project
3 )主启动类需要继承 SpringBootServletInitializer并重写configure
@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder)
{
return builder.sources(DemoApplication.class);
}
}
3 ) 右键工程-run as-maven install
看日志里面生成的war包（demo-web-mybatis.war）。将war拷贝到tomcat的webapp目录下，bin目录下点击startup启动。刚才的war包会自动解压
