SpringBoot实战教程（3.2）——启动指定执行顺序

一、springboot启动类

package com.rule.engine;

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

@SpringBootApplication
public class EngineApplication {

    public static void main(String[] args) {
        SpringApplication.run(EngineApplication.class, args);
    }

}

二、指定启动时加载（@Order(1)指定为第一个加载）

package com.rule.engine.service;

import com.rule.engine.core.LexParser;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;
