springboot启动时--如何打印出已加载所有Bean呢?

下文笔者讲述SpringBoot启动时--打印出所有已加载Bean的方法及示例分享,如下所示

输出Springboot中所有Bean

实现思路：
    使用appContext.getBeanDefinitionNames()方法即可获取
	  SpringBoot中所有Bean

例:
获取SpringBoot中所有Bean

package com.java265;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.commandlinerunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
 
import java.util.Arrays;
 
@SpringBootApplication
public class Application implements CommandLineRunner {
 
    @Autowired
    private ApplicationContext appContext;
 
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
 
    @Override
    public void run(String... args) throws Exception {
 
        String[] beans = appContext.getBeanDefinitionNames();
        Arrays.sort(beans);
        for (String bean : beans) {
            System.out.println(bean);
        }
    }
}

输出量
