Spring MVC的数据库连接

Question

我要创建与数据库的连接在Spring MVC中插入特定的值，但有以下错误在我的servlet-context.xml中，同时创建连接：

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] 

我宣布豆与id="dataSource"但它似乎不工作。你能帮助我理解为什么它找不到声明元素'bean'什么意思

“匹配通配符是严格的”

这里是调度员的代码。提前致谢。

Answer 1

OK，所以问题是，你没有为豆指定通配符，所以你应该写：

<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> 

，然后应该工作。
