服务spring config：

  <!-- Our test service bean -->
  <bean id="UserService"
  class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition"
  lazy-init="true">
  <property name="schemaCollection">
   <bean

  </property>
  <property name="portTypeName" value="UserService" />
  <property name="serviceName" value="UserService" />
  <property name="locationUri" value="/endpoints" />
  </bean>
  </beans>

我有两个项目：dao和services。在dao中，我有一个userLogin映射器并调用了IUserLoginDAO。我在dao项目中创建了一个junit测试类来测试方法和所有方法测试通过了。在服务中，我依赖于dao项目。在服务项目中，我有一个名为UserServiceImpl的类，我尝试使用@Autowired注入IUserLoginDAO。当我在tomcat中部署服务项目时，我收到以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userServiceEndpoints': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.example.services.UserService com.example.services.endpoints.UserServiceEndpoints.userService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.example.dao.IUserLoginDAO com.example.services.UserServiceImpl.userDao; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.example.dao.IUserLoginDAO] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

任何评论都是赞成的！谢谢！

Answer 1

不确定mybatis-spring扫描是否实际支持通配符。您是否尝试过明确定义映射器？

<bean id="userLoginDAO" class="org.mybatis.spring.mapper.MapperFactoryBean">
    <property name="mapperInterface" value="...myMapperInterface" />
    <property name="sqlSessionFactory" ref="sqlSessionFactoryBean" />
</bean>

Spring Bean Injection错误
