Spring Boot中加载初始化数据 两种方法

package com.etonkids.explora.utils;

import com.etonkids.explora.entity.Campus;
import com.etonkids.explora.mapper.CampusMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.stereotype.Component;

import java.util.ArrayList;
import java.util.List;

@Component
public class ApplicationRunnerTest implements ApplicationRunner {
    @Autowired
    private CampusMapper campusMapper;

    
    public static  List campusList=new ArrayList<>();

    @Override
    public void run(ApplicationArguments args) throws Exception {
        System.out.println("ApplicationRunner");
        campusList = campusMapper.selectList(null);
        campusList.forEach(campus -> {
            System.out.println(campus.getCampusName());
        });

    }
}

```java
package com.etonkids.explora.utils;

import org.springframework.boot.CommandLineRunner;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;

@Component
public class CommandLineRunnerTest implements CommandLineRunner {

    @Override
    public void run(String... args) throws Exception {
        System.out.println("CommandLineRunner...");
    }
}
