我有一个要从中调用服务方法的组件。当我尝试打电话时，什么也没发生。服务方法是调用rest api的completablefuture方法。这可能与它有关吗？
我尝试从不同的类调用它，并且它可以工作。只有此类是一个问题。
我从以下位置调用的课程的片段：
@Component
@Scope("prototype")
public class Reader{
///and other variable declarations used
@Autowired
private AsyncServices aService;
public void StartAsync() throws InterruptedException, IOException{
Runnable task = new Runnable() {
@Override
public void run() {
try {
StartInventory();
} catch (Exception ex) {
System.out.print("start inventory thread could not start:
"+ex.getLocalizedMessage());}
}
};
Runnable task2 = new Runnable() {
@Override
public void run() {
try {
StartTCPClient();
} catch (Exception ex) {
System.out.print("start tcpclient thread could not start: "+ex.getMessage());
}
}
};
tcpClientThread = new Thread(task2, "TCPClientThread");
tcpClientThread.setDaemon(true);
tcpClientThread.start();
inventoryThread = new Thread(task, "InventoryThread");
inventoryThread.setDaemon(true);
inventoryThread.start();
public void StartInventory() throws InterruptedException, ExecutionException, ParseException{
......
//calling the method in @service class
aService.findVehicle(rfidtag);
}
code for service:
@Service
public class AsyncServices {
private final RestTemplate appRestTemplate;
@Autowired
public AsyncServices(RestTemplateBuilder builder){
this.appRestTemplate=builder.build();
}
@Async
@Transactional
public CompletableFuture<BmwvehicleTest> findVehicle(String rfidtag) throws InterruptedException{
log.info("trying to find a vehicle test by rfidtag"+ rfidtag);
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
HttpEntity <BmwvehicleTest> entity = new HttpEntity <BmwvehicleTest>(headers);
BmwvehicleTest results=appRestTemplate.exchange("http://localhost/tag/"+rfidtag, HttpMethod.GET, entity, BmwvehicleTest.class).getBody();
return CompletableFuture.completedFuture(results);
}
我希望能够从service方法获得结果，而service方法是从rest api获取结果。
