我beans:profiles在我的xml中使用了这样的代码：

    <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>

我已经spring.active.profiles在web.xml中设置了：

<servlet>
    <servlet-name>myapp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/myapp-servlet.xml</param-value>
    </init-param>
    <init-param>
        <param-name>spring.profiles.active</param-name>
        <param-value>dev</param-value>
    </init-param>
</servlet>

我的代码结构是这样的：

//controller
@Controller 
public class MyController {
  @Autowired
  private MyService myService;
  ....
}

//service implementation
@Service("myservice")
public class MyServiceImpl implements MyService {
  @Autowired
  DBService dbService;
}

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

错误：

创建名称为“
myController”的bean时出错：自动连接的依赖项注入失败；嵌套的异常是org.springframework.beans.factory.BeanCreationException：无法自动装配字段：private
MyService MyController.myService;
嵌套的异常是org.springframework.beans.factory.BeanCreationException：

嵌套的异常是org.springframework.beans.factory.BeanCreationException：创建名称为’dbService’的bean时出错：自动连接依赖项的注入失败；嵌套的异常是org.springframework.beans.factory.BeanCreationException：无法自动装配方法：public
