spring事务如何用

import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test1 {    public void test() {        System.out.println("test1");        ApplicationContext ctx =                 new ClassPathXmlApplicationContext("bean.xml");//到这里就不能继续运行了        System.out.println(ctx);        Transaction ts = (Transaction)ctx.getBean("tsa");        System.out.println("test");        ts.insert("insert into user (id,name,password,age) value(10,'sadasd','12312313',11)");            }}
