需要

1.正常springboot 项目

2.不需要做任何就这一个集成ApplicationRunner  的类 即ok

3.执行的具体任务

4.看如下示例

初始化类

package com.superman.conf.init;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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;

import com.superman.global.service.GlobalAPIService;
import com.superman.job.impl.JobExecute;
 
/**
 * 初始化内容
 * 
 * @author yushen
 *
 */
@Component
@Order(value=1)
public class InitApplicationRunner implements ApplicationRunner{
  
  private static final Logger logger = LoggerFactory.getLogger(InitApplicationRunner.class);
  
  @Autowired
  private JobExecute je;
  
  @Autowired
  private GlobalAPIService gas;
  
  
  /**
   * 开发环境的时候如果有需要可以把这里注释掉，在正式环境的时候调用
   * 如果本地服务器启动的快的话可以直接开启
   * 
   */
  @Override
  public void run(ApplicationArguments args) throws Exception {
    logger.info("初始化任务1--数据记录数量定时任务  开始 ！");
    try {
      je.execute();
    } catch (Exception e) {
      logger.info("初始化任务1 -- 数据记录数量定时任务  失败！");
    }
    logger.info("初始化任务1-- 数据记录数量定时任务  完毕 ！");
    
    logger.info("初始化任务2-- 对外接口启用禁用缓存数据任务  开始 ！");
    try {
      gas.updateCache();
    } catch (Exception e) {
      logger.info("初始化任务2--  对外接口启用禁用缓存数据任务  失败！");
    }
    logger.info("初始化任务2--  对外接口启用禁用缓存数据任务  完毕 ！");
    
    
  }
}

启动类

package com.superman;

import org.apache.log4j.BasicConfigurator;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import com.superman.tonifi.InitInfo;


/**
 * 项目启动类
 * 
 * @author yushen
 *
 */
@SpringBootApplication
public class Provider_App {
  
  /**
   * 项目启动入口
   * 
   * @param args
   */
  public static void main(String[] args) {
    
    SpringApplication.run(Provider_App.class, args);
   
  }
  
}
