我们已经构建了一些程序，该程序调用simplejdbccall进行功能并从postgres数据库中提取数据。通过主程序进行测试时，它工作正常
public class MainApp {
public static void main(String[] args) {
JdbcApplicationDao JdbcApplicationDao1 = new JdbcApplicationDao();
System.out.println("^^^^^^^^^^^^^^^^^^^^^^^^calling getApplicationConnections^^^^^^^^^^^^^^^^^^^");
Collection<ConnectionDto> applicationConnectionList = JdbcApplicationDao1.getApplicationConnections("OneView");
}
其中的getApplication定义如下：
public final Collection<ConnectionDto> getApplicationConnections(String applicationName)
{
LOGGER.info("^^^^^^^^^^^^^^^^^^^^^^^^^^^^^You are in common getApplicationConnections return studentJDBCTemplate1^^^^^^^^^^^^^^^^^^^^^^^^");
ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");
StudentJDBCTemplate1 studentJDBCTemplate = (StudentJDBCTemplate1)context.getBean("studentJDBCTemplate1");
LOGGER.info("^^^^^^^^^^^^^^^^^^^^^Fetch Connections from the database for applicationName^^^^^^^^^^^^^^^^^^^: " + applicationName);
return ( studentJDBCTemplate.getApplicationConnections(applicationName));
}
但是，如果我从第二个模块（即作业管理）调用相同的函数，那么我从函数调用中得到null。看来，spring-jdbc版本存在问题，但我无法弄清
