1、采用非阻塞运行java程序

#优化启动：非阻塞执行，牺牲CPU换取快速启动
CMD java -Djava.security.egd=file:/dev/./urandom  -jar baye-eureka.jar

2、替换boot中的tomcat容器

		<!--web 模块-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
			<exclusions>
				<!--排除tomcat依赖-->
				<exclusion>
					<artifactId>spring-boot-starter-tomcat</artifactId>
					<groupId>org.springframework.boot</groupId>
				</exclusion>
			</exclusions>
		</dependency>
		<!--undertow容器,比tomcat启动快，吞吐量更大-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-undertow</artifactId>
		</dependency>

3、指定JVM参数

#赋予适度内存运行
CMD java  -Xms50m -Xmx300m -jar baye-eureka.jar
