SpringBoot项目在加载完的时候执行的代码

实现CommandLineRunner接口，重写run方法，方法里面的内容就是项目加载完要执行的代码

package com.lixianhe.load;

import com.lixianhe.service.DrugServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Controller;


@Controller
public class CommandLineRunnerController implements CommandLineRunner {

    public static int drugMaxCount;

    @Autowired
    private DrugServiceImpl drugService;


    @Override
    public void run(String... args) {
        // 在项目加载的时候给药品最大数量赋值
        drugMaxCount = drugService.getDrugMaxCount();
        System.out.println(drugMaxCount);
        System.out.println(drugService);
    }
}
