上下文中的多个包：组件扫描、spring config
如何在 spring-servlet.xml 文件的 context:component-scan 元素中添加多个包？
我已经尝试过
<context:component-scan base-package="z.y.z.service" base-package="x.y.z.controller" />
，
<context:component-scan base-package="x.y.z.service, x.y.z.controller" />
但
<context:component-scan base-package="x.y.z.service" />
<context:component-scan base-package="x.y.z.controller" />
出现错误：
org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [x.y.z.dao.daoservice.LoginDAO] found for dependency:
How can I add multiple packages in spring-servlet.xml file in context:component-scan element?
I have tried
<context:component-scan base-package="z.y.z.service" base-package="x.y.z.controller" />
and
<context:component-scan base-package="x.y.z.service, x.y.z.controller" />
and
<context:component-scan base-package="x.y.z.service" />
<context:component-scan base-package="x.y.z.controller" />
but got error:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [x.y.z.dao.daoservice.LoginDAO] found for dependency:

下面的方法是正确的：
注意，错误抱怨的是
xyzdao.daoservice.LoginDAO，它不在上面提到的包中，也许你忘记添加它：The following approach is correct:
Note that the error complains about
x.y.z.dao.daoservice.LoginDAO, which is not in the packages mentioned above, perhaps you forgot to add it:注释方法
Annotation Approach
您可以添加多个基础包（请参阅axtavt的答案 ），但您也可以 过滤基本包内扫描的内容：
You can add multiple base packages (see axtavt's answer), but you can also filter what's scanned inside the base package:
将会起作用，因为其余的包是“xyz”的子包。因此，您无需单独提及每个包。
will work since the rest of the packages are sub packages of "x.y.z". Thus, you dont need to mention each package individually.
另一种通用的注释方法：
Another general Annotation approach:
延迟响应，但要使用基于注释的方法提供多个包，我们可以使用如下所示：
@ComponentScan({"com.my.package.one","com.my.package.subpackage .two","com.your.package.supersubpackage.two"})A delayed response but to give multiple packages using annotation based approach we can use as below:
@ComponentScan({"com.my.package.one","com.my.package.subpackage.two","com.your.package.supersubpackage.two"})如果 xyz 是通用包，那么您可以使用：
它将包含所有以 xyz 开头的包，例如：
xyz控制器、xyz服务等
If x.y.z is the common package then you can use:
it will include all the package that is start with x.y.z like:
x.y.z.controller,x.y.z.service etc.
例如，您有包“com.abc”，并且里面有多个包，您可以使用像
For Example you have the package "com.abc" and you have multiple packages inside it, You can use like
