我的解答思路和尝试过的方法

网上用错误信息搜索了很多帖子说是@Service注解没加还有说tomcat版本和spring版本不兼容的，但我的pom.xml文件和其他配置文件是另一个ssm项目copy过来的，另外Service注解也加了。

我想要达到的结果

本人刚开始学习ssm框架，这个error已经抓头一整天，望大佬救救孩子/(ㄒoㄒ)/~~

Error creating document instance. Cause: org.xml.sax.SAXParseException; lineNumber: 4; columnNumber: 10; 已经看到 doctype。
仔细检查一下配置文件的标签是不是错误了。

把dao层和mapping映射代码发出来，一般这样的错在dao和mapper上

clean一下，重新打包试试

开启注解扫描，也就是你配置文件的第一行 <context:component-scan base-package="com.xiangyun.controller"/>
你service难道不用注入dao吗？这个一般是src下面的扫描
