优惠券项目初始化

1.项目配置

创建之后:

2.pom.xml配置

代码说明：

• <groupId>com.imooc.spingboot.study</groupId>:工程组标识，一般为域名倒写
• <groupId>org.projectlombok</groupId>:getter和setter插件
• <artifactId>spring-boot-starter-test</artifactId>:测试依赖组件
• <artifactId>fastjson</artifactId>:alibaba的json依赖组件

3.编写启动类

新增com.imooc.springboot.study包
新增SpringBootStudyApplication启动类

package com.imooc.springboot.study;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootStudyApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootStudyApplication.class,args);
    }
}

4.启动项目

看到这个界面，说明启动成功:

5.容器启动三种方式：

• 方法1：SpringApplication.run静态方法启动
• 方法2：通过api调整应用行为

SpringApplication application = new SpringApplication(SpringBootStudyApplication.class);
//去除logo
application.setBannerMode(Banner.Mode.OFF);
//设置成非web应用
application.setWebApplicationType(WebApplicationType.NONE); 
application.run(args);

• 方法3(链式调用)：SpringApplicationBuilder的Fluent Api链式调用
