## 启动类 ##

package com.lfsun.springbootlogback;
    
    import lombok.extern.slf4j.Slf4j;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.ConfigurableApplicationContext;
    
    @SpringBootApplication
    @Slf4j
    public class SpringBootLogbackApplication {
        
    
        public static void main(String[] args) {
        
            ConfigurableApplicationContext context = SpringApplication.run(SpringBootLogbackApplication.class, args);
            int length = context.getBeanDefinitionNames().length;
            log.trace("Spring boot启动初始化了 {} 个 Bean", length);
            log.debug("Spring boot启动初始化了 {} 个 Bean", length);
            log.info("Spring boot启动初始化了 {} 个 Bean", length);
