在tomcat运行报错

[cloudstaymoon]

报了很多这种错误： Related cause: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in file [D:\Program Files\Tomcat\apache-tomcat-8.0.35\webapps\production_ssm\WEB-INF\classes\spring\applicationContext-dao.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in file [D:\Program Files\Tomcat\apache-tomcat-8.0.35\webapps\production_ssm\WEB-INF\classes\spring\applicationContext-dao.xml]: Invocation of init method failed; nested exception is java.sql.SQLException: Could not retrieve transation read-only status server

请问是哪里出现问题了呀？期待大佬的回复，谢谢啦~
