java - springmvc 解析spring*.xml配置文件的异常

问题描述

问 题

刚开始接触springmvc

目标：识别基于注解的控制器类（controller）

---

过程如下：

 1.编写注解的controller
 2.在spring*.xml文件中配置
 <context:component-scan base-package="idv.song.controller"/>
 3.重新编译，[重启tomcat]
 4.报错如下

严重: Context initialization failed
org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/config/springmvc-config.xml]; nested exception is java.lang.NoClassDefFoundError: org/springframework/aop/TargetSource

---

报错中加粗的部分都百度[木得google]过了，没有合适的答案

---

自我分析如下：

-- bean没有实例化
-- 配置文件中bean配置的错误（我的配置文件中只有关于识别注解控制器的配置）
--| 尝试去掉<context:component-scan base-package="idv.song.controller"/> -- 编译正常（dispatcherServlet.init（）成功)|
--|base-package没有写错，是不是xml的语法错误或者引用content.xsd版本问题？

问题：识别注解控制器的spring配置文件的正确写法&分析我的问题

 <context:component-scan base-package="idv.song.controller"/>

<!-- register beans that support the controllers that have annotated method -->
<!--     <mvc:annotation-driven></mvc:annotation-driven>
<mvc:resources location="/" mapping="/*.html"></mvc:resources>     -->
 <!--  <bean id="/product_input" class="idv.song.controller.InputProductController"></bean>
<bean id="/product_save"  class = "idv.song.controller.SaveProductController"></bean> -->
  <bean id="veiwResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name="prefix" value="/WEB-INF/jsp/"></property>
      <property name="suffix" value=".jsp"></property>
  </bean></beans>`

解决方案

NoClassDefFoundError 说明类没有找到，看看依赖的包是否缺少spring-aop-*.jar aopalliance-1.0.jar
