求解啊

解决方案

如果你是为了加载spring mvc的配置文件而在web.xml中配置了listener，那么请注意如下：
使用的web容器支持servlet 2.3 或者更高版本的，你可以在web.xml 配置

org.springframework.web.context.ContextLoaderListener

使用的web容器支持servlet2.2 或者较低版本的或者支持2.3，但是在初始化servlet之前并没有初始化listener，你可以在web.xml中配置

context
org.springframework.web.context.ContextLoaderServlet
1

希望对你有用

解决方案二：

补充一下，刚刚的配置文件忘记添加到代码了。
如果你是为了加载spring mvc的配置文件而在web.xml中配置了listener，那么请注意如下：
使用的web容器支持servlet 2.3 或者更高版本的，你可以在web.xml 配置

 <listener>
<listener-class>org.springframework.
web.context.ContextLoaderListener</listener-class>
</listener>

使用的web容器支持servlet2.2 或者较低版本的或者支持2.3，但是在初始化servlet之前并没有初始化listener，你可以在web.xml中配置

 <servlet>
<servlet-name>context</servlet-name>
<servlet-class>org.springframework.
web.context.ContextLoaderServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

希望对你有用

解决方案三：

Could not autowire field: private com.test.entity.Test com.test.service.impl.TestServiceImpl.test; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:
注入域，这个类中bean没有，配置的问题吧
