SpringBoot實現異步多線程

一、啓動類中添加@EnableAsynchtml

@SpringBootApplication
@EnableAsync
public class ModelApplication {
    public static void main(String[] args) {
        SpringApplication.run(ModelApplication.class,args);
    }
}

二、新建異步線程類，並加上相應註解java

package com.ndsc.model.asybc;

import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Component;

@Component
public class AsyncThread {
    @Async
    public void run(){
        System.out.println("異步線程："+Thread.currentThread().getName());
    }
}

三、調用（以農村不起眼的商機controller層調用爲例）react

package com.ndsc.model.controller;

import com.ndsc.model.asybc.AsyncThread;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class MyController {
    @Autowired
    AsyncThread asyncThread;

    @RequestMapping("/testAsync")
    public String testAsync(){
        System.out.println("當前線程："+Thread.currentThread().getName());
        asyncThread.run();
        return "test";
    }
}

四、啓動測試linux

http://localhost:8099/testAsyncweb
