SpringBoot启动类有三种启动方式。

第一种，SpringApplication.run(SpringBootStudyApplication.class,args)

package com.jepcc.example;

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);
    }
}

第二种，new SpringApplication(SpringBootStudyApplication.class).run(args)

package com.jepcc.example;

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

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

第三种，new SpringApplicationBuilder(SpringBootStudyApplication.class).run(args)

package com.jepcc.example;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;

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