我正在创建一个MySQL连接,但我遇到了 applicationContextMySQL 和 web.xml 的问题。
我在 web.xml 中有这个内容。
<?xml version="1.0" encoding="UTF-8"?>

</filter-mapping>
</web-app>
在 applicationContextMySQL .xml中,我有这个内容。
<beans:beans xmlns="http://www.springframework.org/schema/security"

<beans:property name="password" value="" />
</beans:bean>
</beans:beans>
代码中的确切错误。

答案 0 :(得分:0)
您可以在日志中看到:Cannot find class [org.apache.commons.dbcp.BasicDataSource]
您确定已通过添加 commons-dbcp 依赖项导入该类吗?
如果不是这样,只需在 pom.xml 中添加:
<dependency>
<groupId>commons-dbcp</groupId>
<artifactId>commons-dbcp</artifactId>
<version>1.4</version>
</dependency>
