目前为止spring-data-redis 2.1.5.RELEASE 是最新的版本， 但是网上关于此版本的配置太少了，很多注意事项也没说清楚，踩过了不少坑，所以来纪录一下.
注意 ：spring-data-redis 2.1.5.RELEASE 搭配的 jedis的版本是 2.x.x！ 是 2.x.x！ 是 2.x.x ！ 不是3.x.x 重要的事情说三遍！
否则会报如下错误：

import org.springframework.test.context.ContextConfiguration;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml")
public class TestValue {
@Autowired
private RedisTemplate<String, String> redisTemplate;
@Test
public void setValue(){
redisTemplate.boundValueOps("name").set("yongGe");
}
@Test
public void getValue(){
String str = redisTemplate.boundValueOps("name").get();
System.out.println(str);
}
@Test
public void deleteValue(){
redisTemplate.delete("name");
}
}
ok! 成功允许！！！
