Spring - project not running but no error

Question

I have a spring project followed by that tutorial.

Problem: The server starts with the application and does not give any error message. The application does not seem to crash, too. Unfortunately I have the guess that it is not really running.

console output:

Jun 24, 2016 1:39:36 PM org.apache.tomcat.util.digester.SetPropertiesRule begin
WARNUNG: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:SpringDataDemo' did not find a matching property.

It should do some database operation but the database is empty after running the code.

I am not able to debug because Spring Tool Suite does not stop at the breaktpoint.

The only thing I see after running is a 404 message in the browser.

Question: Why does spring not run its main application class?

application class:

public class SpringDataDemo {
    public static void main(String[] args) {
        try {
            ApplicationContext context = new ClassPathXmlApplicationContext("resources\\spring-configuration.xml");

            // Fetch the DAO from Spring Bean Factory
            EmployeeDao employeeDao = (EmployeeDao) context.getBean("EmployeeDaoImpl");
            Employee employee = new Employee("Employee123");
            // employee.setEmployeeId("1");

            // Save an employee Object using the configured Data source
            employeeDao.save(employee);
            System.out.println("Employee Saved with EmployeeId " + employee.getEmployeeId());

            // find an object using Primary Key
            Employee emp = employeeDao.findByPrimaryKey(employee.getEmployeeId());
            System.out.println(emp);

            // Close the ApplicationContext
            ((ConfigurableApplicationContext) context).close();
        } catch (BeansException | SQLException e) {
            e.printStackTrace();
        }
    }
}

Answer 1

The example from the tutorial is a Java Project (not a Dynamic Web one). Thus it should be configured in Eclipse that will use Java launcher to run your application standalone from the command line, i.e. without any web server involved like Tomcat, etc.
