junit常用及junit联合spring

@RunWith(SpringJUnit4ClassRunner.class)  //spring和junit的连接
@ContextConfiguration({"classpath:/spring/applicationContext-test3.xml"}) 
public class SpringTest {
    //Reasource和Autowired 为两种注入方式

@Resource //根据名称找，属于j2ee，不写按类查找
private JdbcTemplate jdbcTemplate; 
// @Autowired //根据类型找，属于spring // private JdbcTemplate jdbcTemplate; 
 @Test publicvoid testGetUserById() 
{ 
Integer userId = 1; String sql = "select count(*) from t_user_test"; 
int count = jdbcTemplate.queryForObject(sql, Integer.class); System.out.println(count); }
 }
