我在我的代碼庫中有一個控制器，它的軟件包沒有被組件掃描。這個控制器也沒有在任何XML中的bean中定義。定義了沒有組件掃描或bean定義的控制器
不知何故，控制器正在工作。我猜這是因爲有一些方法可以在Spring中定義一個沒有組件掃描或在bean中定義它的控制器。然而，這個控制器實現了一個名爲AbstractControllerImpl的類，並且Helper實現類正在獲取組件掃描。
幫助程序獲取組件掃描的事實是否意味着控制器也被掃描？或者，如果不是，這個控制器怎麼可能工作？
@Controller
@RequestMapping("/something")
public class SomeController extends AbstractControllerImpl<SomeControllerHelper> {
//Some request mappings here
}
抽象控制器類它延伸：
public abstract class AbstractControllerImpl<H extends Helper>
implements Controller<H>
{
private H helper;
private BaseValidator validator;
public H getHelper()
{
return helper;
}
public void setHelper(H helper)
{
this.helper = helper;
}
public void setValidator(BaseValidator validator)
{
this.validator = validator;
}
public BaseValidator getValidator()
{
return validator;
}
public Errors doValidation(Object obj)
{
Errors validationErrors = new BindException(this, "");
if (validator != null)
{
validator.validate(obj, validationErrors);
}
return validationErrors;
}
}
Controller接口：
public interface Controller<H extends Helper>
{
H getHelper();
}
助手定義：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="someHelper" class="com.controller.SomeHelperImpl" />
</beans>
助手impl類（這是得到comp onent掃描）：
@Component("SomeControllerHelper")
public class ASomeControllerHelperImpl implements SomeControllerHelper {
//Some methods here
}
編輯：我的web.xml中。我刪除了幾個servlet映射，並改變了一些名字，但這是什麼樣子：

讓我們來看看你的web.xml。你有沒有其他的spring xml上下文文件？你有任何'@ Configuration'類嗎？ –
@SotiriosDelimanolis我添加了我的web.xml，刪除了一些servlet映射。如果有什麼特定的東西，我認爲我應該去尋找那些不在其中的東西，讓我知道，我會看看。在我的整個應用程序中沒有一個'@ Configuration'註釋。 – user886596
你能告訴我們你的班級路徑掃描配置嗎？ –
