我已经从Spring MVC Project Template创建了一个项目，而我的servlet-context就是这样。

我尝试了无数次。我将datasource替换为dbcp一个。然后它说 cannot create Driver of type com.mysql.jdbc.Driver。

我可能无法进行此操作。请帮忙。我现在使用 spring 和 hibernate 。 我在外部添加了 mysql connector，然后我也在tomact/lib中添加了 cannot find suitable driver。在deployemnt中添加但是没有去。有时会说cannot create driver when used with dbcp.然后会说{{1}}

请帮忙。 感谢。

我认为你必须像这样创建META-INF / context.xml; 

<?xml version="1.0" encoding="UTF-8"?>
<Context>

    <!-- Default set of monitored resources -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>

 <Resource  name="jdbc/TestDB" 
            username="xxxx" 
            password="xxxxxxxxxx" 
            driverClassName="com.mysql.jdbc.Driver"
            url="jdbc:mysql://localhost:3306/TestDB"
            auth="Container" 
            type="javax.sql.DataSource"
            maxActive="100" 
            maxIdle="30" 
            maxWait="10000"
            initialSize="1"/>
</Context>

除此之外，您可以查看此question和this寻求帮助。
