springboot中@Async异步调用注解的使用

package com.txc.asynctaskdemo; import com.txc.asynctaskdemo.async.AsyncTaskService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class AsyncController { @Autowired private AsyncTaskService asyncTaskService; @RequestMapping("/testMethod") public String testMethod(){ System.out.println("======主线程开始执行======"); asyncTaskService.asyncMethod("你要传递的数据");//异步执行方法 System.out.println("======主线程结束执行======"); return "index";//返回的视图逻辑地址 } }
