這是一個棘手 - 我在least.Component掃描似乎並沒有工作爲什麼我的@components在spring中未被檢測到？
這裏是web.xml中

我的服務：
@Service("test")
public class ProjServiceImpl extends RemoteServiceServlet implements ProjService {
private static final Log LOG = LogFactory.getLog(ProjServiceImpl.class);
@Autowired
PoiCategDAO poiCategDAO;
public String greetServer(String input) throws IllegalArgumentException {
// Verify that the input is valid.
if (!FieldVerifier.isValidName(input)) {
// If the input is not valid, throw an IllegalArgumentException back to
// the client.
throw new IllegalArgumentException(
"Name must be at least 4 characters long");
}
//RequestContextUtils.getWebApplicationContext(request);
// String serverInfo = getServletContext().getServerInfo();
// String userAgent = getThreadLocalRequest().getHeader("User-Agent");
return "Hello, " + input + "!<br><br>I am running .<br><br>It looks like you are using:<br>";
}
@Override
//@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
public void testdao(Integer id) throws IllegalArgumentException {
// TODO Auto-generated method stub
PoiCateg X=poiCategDAO.findById(id);
PoiCateg z=poiCategDAO.findById(id);
}
}
而且applicaationContext2。 xml

請注意，如果我把上下文：component-s可以在applicationContext.xml（不是applicatinContext2.xml中檢測到我的服務bean。 ）。如果還有其他信息我應該提供。
我不明白你最後一句話的意思：你引用的源代碼是applicationContext2.xml，它包含組件掃描。你說applicationContext.xml包含組件掃描，但不包含applicationContext2.xml。更麻煩的是，你的web.xml指的是application.xml。你能先簡化和清理你的問題嗎？ –
你用什麼方法來確定你的bean是否被掃描？ – gerrytan
等待，最後一句實際上是否：如果我將context：component-scan放入applicationContext.xml（不是applicationContext2.xml），我的服務bean被檢測到。 ??如果是這樣，那很明顯：在Spring中不使用applicationContext2.xml。你沒有在web.xml的contextConfigLocation –
