部分 I. Spring Boot

				
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>			
				
			

				
spring.redis.database=10
spring.redis.host=localhost
spring.redis.port=6379
spring.redis.password=
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=-1
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0
spring.redis.timeout=0
				
			

				
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(Application.class)
public class ApplicationTests {
	@Autowired
	private StringRedisTemplate stringRedisTemplate;
	@Test
	public void test() throws Exception {
		// 保存字符串
		stringRedisTemplate.opsForValue().set("neo", "chen");
		Assert.assertEquals("chen", stringRedisTemplate.opsForValue().get("neo"));
    }
}				
				
			

stringRedisTemplate模板用于存储key,value为字符串的数据

				
	@Autowired
	private StringRedisTemplate stringRedisTemplate;
	
	@RequestMapping("/test")
	@ResponseBody
	public String test() {
		String message = "";
		stringRedisTemplate.opsForValue().set("hello", "world");
		message = stringRedisTemplate.opsForValue().get("hello");
		return message;
	}
				
			

等同于

				
	@Autowired
	private RedisTemplate<String, String> redisTemplate;
				
			

					
	@Autowired
	private RedisTemplate<String, String> redisTemplate;
	
	public List<Protocol> getProtocol() {
		List<Protocol> protocols = new ArrayList<Protocol>();
		Gson gson = new Gson();
		Type type = new TypeToken<List<Protocol>>(){}.getType();
		redisTemplate.setKeySerializer(new StringRedisSerializer());
		redisTemplate.setValueSerializer(new StringRedisSerializer());
		
		String cacheKey = String.format("%s:%s", this.getClass().getName(), Thread.currentThread().getStackTrace()[1].getMethodName());
		long expireTime = 5;
		
		if(redisTemplate.hasKey(cacheKey)){
			String cacheValue = redisTemplate.opsForValue().get(cacheKey);
			System.out.println(cacheValue);
			protocols = gson.fromJson(cacheValue, type);
		}else{
			Protocol protocol = new Protocol();
			protocol.setRequest(new Date().toString());
			protocols.add(protocol);
			
			String jsonString = gson.toJson(protocols, type);
	        System.out.println( jsonString );
			
			redisTemplate.opsForValue().set(cacheKey, jsonString);
			redisTemplate.expire(cacheKey, expireTime, TimeUnit.SECONDS);
		}
		return protocols;
	}
