NoSuchBeanDefinitionException：没有找到类型为 [project.dao.ServiceUserDao] 的符合条件的 bean 以进行依赖
NoSuchBeanDefinitionException: No qualifying bean of type [project.dao.ServiceUserDao] found for dependency
我的 Hibernate Spring 项目有一些问题。我尝试添加一些限定符或更改基础包，但没有帮助。

我不确定这是你问题的原因，但你的 spring 上下文中存在重复：
<context:annotation-config/>
等同于：
<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
你 post 完整的堆栈跟踪了吗？
你能验证 <context:component-scan base-package="project" /> 里面的 "project" 真的是 @Services, @Controller 类 所在的包名吗？
解决 ServiceUserDao 后你可能会遇到的另一个问题是
你得到 UserDaoImpl 无法自动装配。这是因为您还没有启用 @Repository 的扫描。如果我没记错的话，<context:annotation-config/> 不是在扫描 JPA 内容。
所以尝试添加：
<beans:beans ...
...
xsi:schemaLocation="....
http://www.springframework.org/schema/data/jpa
http://www.springframework.org/schema/data/jpa/spring-jpa.xsd">
<!-- Scan @Repositories -->
<repositories base-package="xxx.repositories" />
http://www.baeldung.com/spring-nosuchbeandefinitionexception
你可以看看这篇文章，也许对你有帮助。
2.Cause：没有找到类型为 […] 的符合条件的 bean 以进行依赖
此异常的最常见原因只是试图注入未定义的 bean。
@Component
public class BeanA{
@Autowired
private BeanB dependency;
//...
}
现在，如果在 Spring 上下文中未定义依赖项 BeanB，则 bootstrap 进程将失败，并出现没有此类 bean 定义的异常：
org.springframework.beans.factory.NoSuchBeanDefinitionException:
没有找到类型为 [org.baeldung.packageB.BeanB] 的符合条件的 bean 用于依赖项：
预计至少有 1 个 bean 有资格作为此依赖项的自动装配候选者。
依赖注解：{@org.springframework.beans.factory.annotation.Autowired(required=true)}
我的 Hibernate Spring 项目有一些问题。我尝试添加一些限定符或更改基础包，但没有帮助。

private Session session;
public UserDaoImpl(){
this.session = Main.getSessionFactory().getCurrentSession();
session.beginTransaction();
}
我搜索了我的问题，但没有找到有用的东西。 谢谢

我不确定这是你问题的原因，但你的 spring 上下文中存在重复：
<context:annotation-config/>
等同于：
<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
你 post 完整的堆栈跟踪了吗？
你能验证 <context:component-scan base-package="project" /> 里面的 "project" 真的是 @Services, @Controller 类 所在的包名吗？
解决 ServiceUserDao 后你可能会遇到的另一个问题是
你得到 UserDaoImpl 无法自动装配。这是因为您还没有启用 @Repository 的扫描。如果我没记错的话，<context:annotation-config/> 不是在扫描 JPA 内容。
所以尝试添加：
<beans:beans ...
...
xsi:schemaLocation="....
http://www.springframework.org/schema/data/jpa
http://www.springframework.org/schema/data/jpa/spring-jpa.xsd">
<!-- Scan @Repositories -->
<repositories base-package="xxx.repositories" />

2.Cause：没有找到类型为 […] 的符合条件的 bean 以进行依赖 此异常的最常见原因只是试图注入未定义的 bean。
@Component
public class BeanA{
@Autowired
private BeanB dependency;
//...
}
现在，如果在 Spring 上下文中未定义依赖项 BeanB，则 bootstrap 进程将失败，并出现没有此类 bean 定义的异常：
org.springframework.beans.factory.NoSuchBeanDefinitionException:
没有找到类型为 [org.baeldung.packageB.BeanB] 的符合条件的 bean 用于依赖项： 预计至少有 1 个 bean 有资格作为此依赖项的自动装配候选者。 依赖注解：{@org.springframework.beans.factory.annotation.Autowired(required=true)}
