Question

我有一个春季项目，然后是tutorial。

问题：服务器从应用程序启动，不会给出任何错误消息。该应用程序似乎也没有崩溃。不幸的是，我猜测它并没有真正运行。

控制台输出：

WARNUNG: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:SpringDataDemo' did not find a matching property.

应该执行一些数据库操作，但运行代码后数据库为空。

我无法调试，因为Spring Tool Suite没有停在断点处。

运行后我唯一看到的是浏览器中的404消息。

问题：为什么spring不运行其主应用程序类？

应用程序类：

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

本教程中的示例是Java项目（不是动态Web项目）。因此，它应该在Eclipse中配置，它将使用Java启动程序从命令行独立运行您的应用程序，即不涉及像Tomcat等任何Web服务器。

Spring - 项目没有运行但没有错误
