我新的春天，並試圖使用Spring，而做一個簡單的程序，我收到以下錯誤錯誤創建bean名字「T」
WARNING: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 't' defined in class path resource [resources/spring.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'driver' of bean class [beans.Test]: Bean property 'driver' is not writable or has an invalid setter method.

一些程序，這是我的Spring.xml文件
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"

Test.java
package beans;

System.out.println("Connection Opened");
}
public void insert(int id,int age, String first, String last)throws Exception

PreparedStatement ps=con.prepareStatement("insert into employee vvalues(?,?,?,?)");
ps.setInt(1, id);
ps.setInt(2, age);
ps.setString(3, first);

ps.executeUpdate();
System.out.println("Successfully Inserted");

@Override

con.close();
System.out.println("Connection Closed");
}
}
的Main（）
package test;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Client
{
public static void main(String[] args)
{
ConfigurableApplicationContext cap=new ClassPathXmlApplicationContext("resources/spring.xml");
}
}
這可能是什麼原因造成的？
我正在使用Eclipse Oxygen基本上這是使用JDBC的一些概念，我試圖測試Spring生命週期屬性。
