查看maven依赖命令： mvn dependency:tree
控制台打印如下：

需要排除某个依赖，在pom.xml文件中添加：
排除tomcat依赖。
<dependencies>
<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>
</dependencies>
mvn dependency:tree 控制台打印如下，发现exclusion tomcat之后：tomcat已经剔除

spring-boot-maven-plugin为Spring Boot Maven插件，提供了：
把项目打包成一个可执行的超级JAR（uber-JAR）,包括把应用程序的所有依赖打入JAR文件内，并为JAR添加一个描述文件，其中的内容能让你用java -jar来运行应用程序。
maven打包命令，cmd进入项目根目录下面。
mvn clean package -Dmaven.test.skip=true
打包生成jar文件，使用java -jar 包名称启动项目，而不是java 包名称.jar 这个默认启动的是class文件
启动成功之后在ie地址栏访问成功
