Springboot 集成redis

這裏只作單機版簡單集成，不過爲項目中使用

1.在pom文件中引入支持

<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-data-redis</artifactId>
		</dependency>
        <!-- springboot2.0的redis整合包多出lettuce鏈接池，須要commons-pool2 -->
		<dependency>
			<groupId>org.apache.commons</groupId>
			<artifactId>commons-pool2</artifactId>
		</dependency>

2.直接在類中注入使用RedisTemplate

@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisTest {

	@Autowired
	private StringRedisTemplate stringRedisTemplate;

	@Autowired
	private RedisTemplate<String, User> redisTemplate;

	@Test
	public void test() throws Exception {
		stringRedisTemplate.opsForValue().set("bbb", "222");
		System.out.println(stringRedisTemplate.opsForValue().get("bbb"));
	}

	@Test
	public void testObj() throws Exception {
		User user = new User();
		user.setUserName("sean");
		user.setPassWord("sean@123");
		ValueOperations<String, User> operations = redisTemplate.opsForValue();
		operations.set("com.jiafeng", user);
		operations.set("com.jiafeng.f", user, 1, TimeUnit.SECONDS);
		Thread.sleep(1000);

		boolean exists = redisTemplate.hasKey("com.jiafeng.f");
		if (exists) {
			System.out.println("exists is true");
		} else {
			System.out.println("exists is false");
		}

	}

}

在SpringBoot2.0以後，spring容器是自動的生成了StringRedisTemplate和RedisTemplate<Object,Object>，能夠直接注入。
