用maven整合ssh框架的时候一直报错，搜索过很多答案，对比自己的配置，自己并无错误。

1.错误信息：

2.spring 配置文件：

		<!--读取属性配置文件内容-->
		<context:property-placeholder location="classpath:db.properties"/>
		
		<!--配置c3p0数据源-->
		<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		    <property name="driverClass" value="${jdbc.driver}"/>
		    <property name="jdbcUrl" value="${jdbc.url}"/>

	<bean id="zhiHuTopicProcessor" class="cn.yll.myCrawler.processor.ZhiHuTopicProcessor" ></bean>
	
</beans>

3.在bean中已经添加注解（这是其中一个，其他的配置也和这个一样）

@Component("zhiHuTopicProcessor")
public class ZhiHuTopicProcessor implements PageProcessor {
	
	private Site site=Site.me().setRetryTimes(3).setSleepTime(1000);
	//ZhiHuTopic属性
	private String topicTitle;
	private String topicUrl;
	private String topic_Description;
	private String topic_Questinos_count;
	private String topic_Followers_count;
	
	@Autowired
	private ZhiHuTopic zhiHuTopic;

4.我自己考虑过是否jar包冲突的问题，但是暂时没有解决。，这是pom.xml

能否归途做我良人 2021-12-08 23:40:14

那应该和什么有关呢？

羁拥 2021-12-08 23:39:58

你项目的classoath下没有报出异常的那个类

筱武穆 2021-12-08 23:39:42

和配置没有关系

柳絮泡泡 2021-12-08 23:39:12

这个很明显，是类找不到，和spring没有关系。简单的说，就是类加载器找不到这个类的.class文件进行加载

飘然心甜 2021-12-08 23:37:56

我是用注解的方式。我在spring的配置文件中已经开启了注解，而且在对应的类上已经添加了注解

剑心龙吟 2021-12-08 23:37:29

你可以用简单的xml试试，即不用服务器加载配置，用ClassPathXmlApplicationContext手动加载，看看是否加载到了ZhiHuTopicDao

天涯离梦残月幽梦 2021-12-08 23:33:08

所以就是真的找不到原因么？

各自安好 2021-12-08 23:29:45

估计java文件没有编译过去

路还长，别太狂 2021-12-08 23:00:11

ZhiHuTopicDao ClassNotFound

容器都初始化失败了

少女净妖师 2021-12-08 22:12:12

那真的就是你的maven库有问题��

后知后觉 2021-12-08 17:06:16

引用来自“内存不够了”的评论

这种问题如果对配置不理解的话，直接重新百度配置吧
