Property ‘driverclassname’ must not be empty

by

The error message you are seeing, “property ‘driverclassname’ must not be empty,” typically occurs when you are configuring a database connection and have not specified the driver class name for the JDBC driver.
The driver class name is required to load the appropriate driver and establish a connection to the database.

Here is an example of how you can specify the driver class name when configuring a database connection: 

    
      <!-- Assuming you are using MySQL -->
      <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
          <property name="driverClassName" value="com.mysql.jdbc.Driver" />
          <property name="url" value="jdbc:mysql://localhost:3306/mydatabase" />
          <property name="username" value="root" />
          <property name="password" value="password" />
      </bean>
