Невозможно создать JDBC-драйвер класса 'com.mysql.jdbc.Driver' для подключения URL 'jdbc: mysql // localhost: 3306/

Question

Я создал проект из шаблона проекта Spring MVC, и мой сервлет-контекст как таковой.

Я попытался innnumerable число раз. Я заменил datasource на dbcp. затем он говорит cannot create Driver of type com.mysql.jdbc.Driver.

Некоторые, как я не могу получить этот прогон. Пожалуйста помоги. Я сейчас использую весна с спящий режим. Я внешне добавил mysql connector, а затем поместил то же самое в tomact/lib. добавлено в deployemnt также, но нет. Несколько раз он говорит cannot find suitable driver, а затем он говорит cannot create driver when used with dbcp.

Пожалуйста, помогите. Спасибо.

Я думаю, что вы должны создать META-INF/context.xml, как это;

<?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>
