Spring MVC数据库连接

我必须创建与数据库的连接以在Spring MVC中插入某些值，但在创建连接时，我的servlet-context.xml中存在以下错误：

Multiple annotations found at this line: - Cannot locate BeanDefinitionParser for element [bean] - cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'bean'. - Configuration problem: Cannot locate BeanDefinitionParser for element [bean] Offending resource: file [E:/General Workspace/Spring Workspace/Record_mvc/ src/main/webapp/WEB-INF/spring/appServlet/servlet-context.xml]

我已经用

id=“dataSource”

声明了bean，但它似乎不起作用。您能帮助我理解为什么它找不到元素

'bean'

的声明，以及它的含义吗

“匹配的通配符是严格的”

这是dispatcher的代码。提前谢谢

好的，问题是您没有为bean指定通配符，所以您应该写：

<beans:bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:8080/leadmanager" />
        <property name="username" value="root" />
        <property name="password" value="root" />
</beans:bean>

---

然后是应该工作。

请提供更多代码。“dataSource”可能有问题bean id=dataSource的第行有错误。在该行找到多个批注：-找不到元素[bean]的BeanDefinitionParser]-cvc复杂类型。2.4.c:匹配的通配符很严格，但找不到元素“bean”的声明。-配置问题：找不到元素[bean]的BeanDefinitionParser有问题的资源：文件[E:/General Workspace/Spring Workspace/Record\u mvc/src/main/webapp/WEB-INF/Spring/appServlet/servlet context.xml]检查谢谢m.aibin错误现在消失了。我可以知道问题出在哪里吗？如果你知道Spring MVC有什么好的门户网站，那就建议我吧，因为我已经通过了Spring.io文档，但是我没有注意到错误。基本知识：-但是要小心，有些答案很旧。比谷歌和spring.io；）请勾选框以获得正确答案；）再次感谢您，我已经从Mkyong教程中学习了语法分析，我也学习了spring.io。
