【JAVA】java异步处理业务，避免阻塞

java异步执行:

import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

    @Autowired
    private ThreadPoolTaskExecutor threadPoolTaskExecutor;

    public String getStr(){
       /**
       主业务
       */
       //异步推送
       threadPoolTaskExecutor.submit(new Runnable() {
           @Override
           public void run() {
               //异步执行业务
           }
       });
       return "xxxxxx";
    }
