Telosys工具Java - 从MySQL数据库生成CRUD UI，BeanCreationException

Question

我想为使用Spring 4.1.1和Hibernate 4.3.6的MySQL数据库开发基本的创建，读取，更新和删除功能。 我正在尝试使用Telosys tools，但在完成tutorial的每一步后，我在Tomcat启动期间遇到了这些错误。

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.

这是在教程之后创建的项目结构。

我怎样才能使这个工作，我寻找的实现 它创建的服务接口，但我无法在整体中找到它们 项目。我必须手动编写吗？

不，没有什么可以用Telosys Tools手动编写，但要小心有两种方法来生成Spring MVC Web应用程序：

1. 带有Spring MVC＆＃39;的捆绑包+＆＃39; Spring Data＆＃39; ：

   捆绑：＆＃39; front-springmvc＆＃39; +＆＃39; service-springdatajpa＆＃39; +＆＃39; persistence-springdatajpa＆＃39;

2. 带有Spring MVC＆＃39;的捆绑包+＆＃39; JPA＆＃39; （没有Spring Data的经典JPA）：

   捆绑：＆＃39; front-springmvc＆＃39; +＆＃39; service-jpa＆＃39; +＆＃39; persistence-jpa＆＃39;

只选择一种方式，不要与其他捆绑包混用。

关于错误，Spring似乎无法找到您的“DMS服务”的实现。接口。此实施由＆＃39; service-xxx ＆＃39;生成。束。 默认情况下，生成的服务类位于包“ xxxx.business.service.impl ＆＃39;使用＆＃39; @Component ＆＃39;允许Spring使用它们的注释。检查（重新生成＆＃39;服务层＆＃39;必要时）

您还可以检查弹簧配置文件（例如applicationContext.xml） ＆＃39;组件扫描基础包＆＃39;必须参考你的包裹
