 3     @Before
 4     public void init() {
 5         applicationContext = new ClassPathXmlApplicationContext(
 6                 "classpath:applicationContext.xml");
 7     }

 9     @Test
10     public void testJedisPool() {
11     JedisPool pool = (JedisPool) applicationContext.getBean("jedisPool");
12             try  {
13             jedis = pool.getResource();
14             
15             jedis.set("name", "lisi");
16             String name = jedis.get("name");
17             System.out.println(name);
18         }catch(Exception ex){
19             ex.printStackTrace();
