SpringBoot另起线程回调

场景

测试的时候需要另起一个线程去模拟第三方回调

引入ThreadPoolTaskExecutor类

• 配置ThreadPoolTaskExecutor类

@Configuration
public class ThreadPoolTaskConfig {


    @Bean(name="threadPoolTaskExecutor")
    public ThreadPoolTaskExecutor executor(){
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        //此方法返回可用处理器的虚拟机的最大数量; 不小于1
        int core = Runtime.getRuntime().availableProcessors();
        executor.setCorePoolSize(core);//设置核心线程数
        executor.setMaxPoolSize(core*2 + 1);//设置最大线程数
        executor.setKeepAliveSeconds(3);//除核心线程外的线程存活时间
        executor.setQueueCapacity(40);//如果传入值大于0，底层队列使用的是LinkedBlockingQueue,否则默认使用SynchronousQueue
        executor.setThreadNamePrefix("thread-execute");//线程名称前缀
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());//设置拒绝策略
        return executor;
    }
}

• 使用ThreadPoolTaskExecutor

@Autowired
private ThreadPoolTaskExecutor taskExecutor;

//10秒以后自动回调
taskExecutor.execute(() -> {
    try {
        Thread.sleep(10000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    Map<String, String> requestData = new HashMap<>();
    requestData.put("orderNo", providerResultDTO.getOrderNo());
    requestData.put("providerOrderNo", providerResultDTO.getProviderOrderNo());
    HttpClientUtil.post("http://localhost:8091/exchange/egift/exchange/rest/v_1/callback/10068", requestData);
});
