@AutoWired beans使用beans后不加载：spring 3.1中的配置文件

Question

    <beans profile="dev">
        <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource">
            <property name="driverClassName" value="${jdbc.driverClassName}" />
            <property name="url" value="${jdbc.internal.url}" />
            <property name="username" value="${jdbc.internal.username}" />
        </bean>
   </beans>

<servlet>
    <servlet-name>myapp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

//db service
@Service("dbservice)
public class DBServiceImpl implements DbService {
  @Autowired
  public void setDataSource (Datasource ds) { 
    this.jdbcTemplate = new JdbcTemplate(ds);

}

错误：

创建名为“My Controller”的bean时出错：注入autowired依赖项失败；嵌套异常为org.SpringFramework.Beans.Factory.BeanCreationException：无法自动连接字段：private MyService MyController.MyService；嵌套异常为org.SpringFramework.Beans.Factory.BeanCreationException：

嵌套异常为org.springframework.beans.factory.beanCreationException：创建名为“db service”的bean时出错：注入autowired依赖项失败；嵌套异常为org.springframework.beans.factory.BeanCreationException：无法自动连接方法：public void dbserviceimpl.setDataSource（javax.sql.DataSource）；嵌套异常为org.springframework.beans.factory.noSuchBeanDefinitionException：未找到依赖项的[javax.sql.datasource]类型的匹配bean：至少需要一个符合此依赖项自动候选条件的bean。依赖项批注：{}在org.springframework.beans.factory.annotation.autowredanNotationbeanpostprocessor.postprocesspropertyvalues（autowredanNotationbeanpostprocessor.java:287)在org.springframework.beans.factor.support.abstractautowirecapablebeanfactor.populateBean（abstractautorecapablebeanfactor.java:1106)在

我猜您是在DispatcherServlet上下文中使用profile，而DataSource可能位于根应用程序上下文中。

请参阅Spring Framework中ApplicationContext.xml和Spring-Servlet.xml之间的区别

更新：尝试使用上下文参数（取自此处）：

<context-param>
<param-name>spring.profiles.active</param-name>
<param-value>dev</param-value>
</context-param>
