java - Spring 问题 : Error creating beans and Injection of autowired dependencies failed

转载作者：行者123 更新时间：2023-12-03 11:18:54

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。

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 Controller 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 Controller 。但是抛出了一个巨大的错误日志，我将在本文末尾分享。

这些是我的依赖项:

junit 4.12

spring-webmvc 4.1.6.RELEASE

spring-context 4.1.6.RELEASE

spring-web 4.1.6.RELEASE

最佳答案

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.ve.common.service.StockService]

错误本身表明 SpringContainer 找不到名称为 的 bean StockService .所以要么你在 applicationContext.xml 中创建 bean使用 @Bean 文件或声明 bean注解。

@Autowired :这个注解允许你不用在 applicationContext.xml 中显式声明你的 bean .但是您必须使用 @Bean 创建要 Autowiring 的类的 bean注释和添加 <context:conponent-scan>在 XML要知道正在使用 @Bean 创建 bean注解。

声明 Bean:声明 bean 用 @Bean 注释方法注释就像

@Configuration
public class AppConfig {
    @Bean
    public StockService stockService() {
        return new StockServiceImpl();
    }
}

这相当于在 applicationContext.xml 中声明 bean

<beans>
    <bean name="stockService" class="com.ve.common.service.StockServiceImpl"/>
</beans>

或

如果您想使用 @Autowired bean 类中的注释必须首先使用以下配置在 spring 中启用注释:

<context:annotation-config />

或者

<bean class ="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
