如何在spring中加注解？

1. Dao-@Repository ( "userDao")

相当于写的

的配置文件

@Autowired //属性的输入

@Overridel

public void setsqlsessionFactory

(sqlsessionFactory sqlsessionFactory) {

super.setsqlsessionFactory(sqlsessionFactory) ;

} //自动注入

测试：

import java.util.List;

Import org.springframework.context.ApplicationContext;

Import org.springframework.context.support. ClassPathXmlApplicationContext;

import cn.sxt.dao.UserDao;

public class Test {

public static void main ( String[] args) {

ApplicationContext ac = new

ClassPathXmlApplicationContext("applicationContext.xml");

UserDao userDao = (UserDao)ac.getBean( "userDao" );

List list = userDao.getAll();

System. out.println(list.size());
