SpringBoot实战教程（3.2）——启动指定执行顺序

今天药忘吃喽~ 2024-04-17 05:54 23阅读 0赞

## 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;
