只需三步！SpringBoot启动异步线程执行任务

1.在Application启动类上加@EnableAsync注解

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

2.在要执行的异步代码块上加@Async注解

@Async
    public void excudeThread(ReportRequest request, IndustryExplore industryExplore) {
        //业务代码
    }

3.注意，要想实现任务的异步调用，同类中方法调方法是实现不了的，请看错误示例

@Service
public class IndustryServiceImpl implements IndustryService {

    @Override
    @Transactional(rollbackFor = Exception.class)
    public void sendReport(ReportRequest request) throws InterruptedException {
        executeThread(request, industryExplore);
    }
    
    @Async
    public void executeThread(ReportRequest request, IndustryExplore industryExplore) {
        //业务代码
    }
}

想要异步调用executeThread的方法，需要将它写在另一个类中再进行调用，请看正确代码

@Service
public class IndustryServiceImpl implements IndustryService {
    @Autowired
    IndustryServiceAsyncImpl industryServiceAsync;

    @Override
    @Transactional(rollbackFor = Exception.class)
    public void sendReport(ReportRequest request) throws InterruptedException {
        industryServiceAsync.executeThread(request, industryExplore);
    }
}

@Service
public class IndustryServiceAsyncImpl {

    @Async
    public void executeThread(ReportRequest request, IndustryExplore industryExplore) {
        //业务代码
    }
    
}
