Spring Issues: Error creating beans and Injection of autowired dependencies failed
提问by arrigonfr
So i'm trying to learn spring and i've been reading a lot of tutorials and trying copying some code from a project that I have in a flash drive.
所以我正在尝试学习 spring 并且我已经阅读了很多教程并尝试从我在闪存驱动器中的项目中复制一些代码。
I already set up tomcat and it works find but i'm still having some problems here. The thing is I can normally access a controller's action from my browser without a problem, but when I started adding annotations and ContextLoaderListener it gave me a 404 status all the time. I don't know what I did, but by tweaking some things around, my browser at least tries to reach the controller again. But throws a huge error log which I will share at the end of this post.
我已经设置了 tomcat 并且它可以正常工作，但是我在这里仍然遇到一些问题。问题是我通常可以毫无问题地从浏览器访问控制器的操作，但是当我开始添加注释和 ContextLoaderListener 时，它一直给我 404 状态。我不知道我做了什么，但是通过调整周围的一些东西，我的浏览器至少会尝试再次访问控制器。但是抛出了一个巨大的错误日志，我将在本文末尾分享。

My model is a basic Entity class that implements Serializable (created by JPA tools).
Now this is my project structure, I'm sorry I couldn't make the image smaller (i'm in a ruch at the moment).
我的模型是一个基本的实体类，它实现了 Serializable（由 JPA 工具创建）。现在这是我的项目结构，很抱歉我不能把图像变小（我现在很忙）。
And here is a quote of that huge error i get in my browser when i access "http://localhost:4848/spring2/api/welcome/hi" or "http://localhost:4848/spring2/api/stock/list"

I apologize for the excessive code blocking and blockquoting, but I think the more information I provide, the better help I can get. And I thank in advance whoever can give me a hand.
对于过多的代码阻塞和引用，我深表歉意，但我认为我提供的信息越多，我能得到的帮助就越好。我预先感谢任何可以帮助我的人。

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.ve.common.service.StockService]
org.springframework.beans.factory。NoSuchBeanDefinitionException：没有类型为 [com.ve.common.service. 股票服务]
The error itself says that SpringContainer doesn't find the bean with nameStockService. So either you create bean in applicationContext.xmlfile or declare bean with the @Beanannotation.
错误本身表明SpringContainer 没有找到 name 的 beanStockService。因此，要么在applicationContext.xml文件中创建 bean，@Bean要么使用annotation声明 bean。
@Autowired:This annotation allows you to not explicitly declaring your bean in applicationContext.xml. But you have to create bean of class you want to autowire using @Beanannotation & add <context:conponent-scan>in XMLto know the bean is being created using @Beanannotation.
@Autowired：这个注解允许你不用在applicationContext.xml. 但是，你必须创建你想用自动装配类的bean@Bean的注释和补充<context:conponent-scan>在XML知道正在使用创建bean的@Bean注解。
Declaring Bean :To declare bean annotate the method with @Beanannotation just like
声明 Bean :声明 bean 用注释对方法进行@Bean注释，就像
@Configuration
public class AppConfig {
@Bean
public StockService stockService() {
return new StockServiceImpl();
}
}
This is equivalent to declaring bean in the applicationContext.xml
这相当于在 applicationContext.xml
<beans>
<bean name="stockService" class="com.ve.common.service.StockServiceImpl"/>
</beans>
OR
或者
If you want to use @Autowiredannotation in a bean class then must first have to enable annotation in spring using below configuration:
如果要@Autowired在 bean 类中使用注释，则必须首先使用以下配置在 spring 中启用注释：
<context:annotation-config />
or
或者
<bean class ="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>

Problem is with your web.xml. Please change the contextconfiglocation to the following
问题在于您的 web.xml。请将 contextconfiglocation 更改为以下内容
<context-param>
<param-name>contextConfigLocation</param-name>
