Telosys工具Java - 從MySQL數據庫生成CRUD UI，BeanCreationException

Question

我想爲使用Spring 4.1.1和Hibernate 4.3.6的MySQL數據庫開發基本的創建，讀取，更新和刪除功能。 我正在嘗試使用Telosys tools作爲目的，但在完成tutorial上的每一步之後，我在Tomcat啓動過程中遇到了這些錯誤。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dmsController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.mywebadmin.business.service.DMSService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

這是在教程後創建的項目結構。

我怎樣才能得到這個工作，我找了創建 服務接口的實現，但在整個 項目，我無法找到他們。我必須手動編寫它們嗎？

Answer 1

沒有，沒有什麼與Telosys工具手工寫，但要小心，有2種方式來生成Spring MVC的Web應用程序：

1. 與束爲「Spring MVC的」 +「春數據'：

   捆綁： '前用SpringMVC' + '服務springdatajpa' + '持久性springdatajpa'

2. 與束關於 'Spring MVC的' + 'JPA'（古典JPA沒有Spring數據）：

   個

   捆綁：「前用SpringMVC」 +「服務JPA」 +「持久性JPA」

選擇只有一條路，不與其他包混合。

關於錯誤，似乎Spring無法找到'DMSService'接口的實現。此實現由'service-xxx'包生成。 默認情況下，生成的服務類位於包含'xxxx.business.service.impl'的'@Component'註釋中，允許Spring使用它們。檢查（重新生成「服務層」如果需要的話）

您還可以查看spring配置文件（如applicationContext.xml中） 的「組件掃描基礎包」必須是指你的包
