我正在启动一个 Primefaces/Spring/Hibernate 项目，并且我仍在学习如何正确处理这些组件。但就在这个时候，我遇到了一个与 spring 依赖注入(inject)相关的问题，这让我很害怕。我已经在网上寻找了两天的答案，但找不到我的代码有什么问题。我已经尝试了两种 Autowiring 方法(@Autowire ans @Inject)。有人可以看看我的代码并检查出了什么问题吗？我的代码如下。
这是部署期间的错误日志:

提前致谢。
最佳答案
Spring 正在尝试 Autowiring PessoaServiceImpl 类中的 PessoaDAO bean(默认情况下按类型完成)，但是没有那种类型的 bean。
您可以在堆栈跟踪中看到这一点:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [br.com.centralemprestimos.sisat.persistence.PessoaDAO]
我假设 PessoaDAO 是一个接口(interface)，而您的意思是 PessoaDAOImpl 来实现它。如果您让此类实现接口(interface)，Spring 应该按类型 Autowiring bean。
@Repository
public class PessoaDAOImpl extends GenericDAOImpl<Pessoa> implements PessoaDAO{
}
关于java - 部署期间的 Spring 依赖注入(inject)问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21505301/
