springboot小笔记

如果默认通过IDEA的springboot 插件布置的 的初始启动类是这样的，这种就是一个普通的java类，只能以jar打包

package com.how2java.springboot;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class SpringbootApplication {public static void main(String[] args) {SpringApplication.run(SpringbootApplication.class, args);}
}

假如想以打包成war包， 想放到tomcat 的webapp里 那么改成下面这个启动类

package com.how2java.springboot;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;@SpringBootApplication
@ServletComponentScan
public class Application extends SpringBootServletInitializer {@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder application) {return application.sources(Application.class);}public static void main(String[] args) {SpringApplication.run(Application.class, args);}
}

新建的 Spring-Boot没有WEB-INF 目录
