Spring-MVC-創建名稱為'procesarController'的bean時出錯：自動連接依賴項的注入失敗

Question

我在使用spring時遇到問題，在服務器中啟動應用程序時出現此錯誤消息，請提前幫助！！

Answer 1

因此，最終的異常如下：

java.lang.IllegalStateException：無法針對資源元數據對bean類[com.zonagifts.web.service.TransaccionServiceImpl]進行內省：找不到它依賴的類

查看您的TransaccionServiceImpl類，您的類路徑中可能缺少一些東西。

• org.tempuri.GiftCardsSoapProxy
• com.zonagifts.web.controller.LoginController

還有其他一些，但這兩個給了我最大的停頓。

您可以驗證這兩個文件（或它們的jar文件）是否在已部署的類路徑中？

Answer 2

查看我的servlet.xml之后，我發現您沒有context：annotation-config標記。 當您使用注釋連接bean時，需要在xml中包含此標記。

<context:annotation-config></context:annotation-config>

由於該接口只有一個實現，並且組件掃描已打開，所以我認為您不需要限定bean。 但是，即使添加了context：annotation-config標記后，應用仍然無法運行，請嘗試限定Bean。 您可以符合以下條件

用@service（“ transaccionServiceImplBean”）注釋TransaccionServiceImpl類，然后在ProcesarController中對其進行連線時， 請提供以下限定符

@Autowired
@Qualifier("transaccionServiceImplBean")
private TransaccionService transaccionService;
