Spring @Autowired在@Endpoint中不起作用
[英]Spring @Autowired not work in @Endpoint
問題描述
我想通過Spring框架創建一些Web服務，但發現錯誤，@ @Autowired在@Endpoint中@Endpoint 。 請查看我的代碼：
@Endpoint
public class VideoEndpoint
{
private VideoService videoService;
@Autowired
public VideoEndpoint(VideoService videoService)
{
this.videoService=videoService;
}
@PayloadRoot(namespace = "http://www.skysoft.top/ws/video", localPart = "GetVideoRequest")
@ResponsePayload
public GetVideoResponse findVideoById(@RequestPayload GetVideoRequest request)
throws Exception
{
GetVideoResponse response = new GetVideoResponse();
Video video=videoService.getVideoByAid(request.getAid());
response.setVideo(video);
return response;
}
}
public interface VideoService {
List<Video> getVideoList();
Video getVideoByAid(long aid);
}
@Service("videoService")
@Transactional
public class VideoServiceImpl implements VideoService {
private final Logger LOG = LoggerFactory.getLogger(this.getClass());
@Autowired
private VideoDao videoDao;
@Autowired
private RedisCache cache;
@Override
public List<Video> getVideoList() {
String cache_key=RedisCache.CAHCENAME+"|getVideoList";
//先去緩存中取
List<Video> result_cache=cache.getListCache(cache_key, Video.class);
if(result_cache==null){
//緩存中沒有再去數據庫取，並插入緩存（緩存時間為60秒）
result_cache=videoDao.queryAll();
cache.putListCacheWithExpireTime(cache_key, result_cache, RedisCache.CAHCETIME);
LOG.info("put cache with key:"+cache_key);
}else{
LOG.info("get cache with key:"+cache_key);
}
return result_cache;
}
@Override
public Video getVideoByAid(long aid) {
return videoDao.queryByAid(aid);
}
}

我通過SoapUI請求Web服務，但是它總是出錯：

我找到了很多解決方案，但是沒有用。

我不是專家，但我認為您的端點類不了解您的applicationContext。 將此放在您的web.xml的頂部
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-*.xml</param-value>
</context-param>
您定義的每個* -servlet.xml文件都將具有不同的上下文，“ contextLoaderListener”將創建一個父上下文，以便您可以在上下文之間共享Bean。
如果那不起作用，請嘗試將其添加到<beans>標簽內的Spring-ws-servelet.xml中
<import resource="spring-service.xml"/>
