springboot项目如何把系统打成war包，部署到tomcat下
1. 修改pom文件打包方式为war
<groupId>com.xx.xx</groupId> <artifactId>demo</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging>
2. pom文件中将下面代码注释解开，打包排除tomcat依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency>
3. 项目左键run as maven-clean，然后run as maven-install,在target目录下出现war包,改好名字，放到tomcat的webapps目录下，启动tomcat，就直接解析用了。
