springboot2.调用redis cluster

一、背景
业务背景就是在springcloud中增加缓存层，只是简单用redis cluster作为缓存组件，设置不同的缓存容器和缓存过期时间，没有涉及缓存的自动刷新。
二、工具
spring boot 2.0.0; spring cloud ; redis cluster 6.2
三、流程

2.服务项目的配置文件信息

  redis:
    cluster:
      nodes: 192.168.110.128:7000,192.168.110.128:7001,192.168.110.128:70002,192.168.110.128:7003,192.168.110.128:7004,192.168.110.128:7005
      # 执行命令超时时间 需要指定单位
      timeout: 15000ms
      # 执行命令超时时间 不需要指定单位
      # timeout: 15000
      # 跨集群执行命令时要遵循的最大重定向数量
      max-redirects: 5
  cache:
    #缓存的名称集合，多个采用逗号分割
    cache-names:
    #缓存的类型，官方提供了很多，这里我们填写redis
    type: redis
    redis:
      #是否缓存null数据，默认是false
      cache-null-values: false
      #redis中缓存超时的时间，默认60000ms
      time-to-live: 60000ms
      #缓存数据key是否使用前缀，默认是true
      use-key-prefix: false
      #缓存数据key的前缀，在上面的配置为true时有效
      key-prefix:
 massage:  
   data:
    name: mydefine
    #结构化信息缓存配置,默认超时时间为2m
    struct-live-to-time: 2
    #对象化信息缓存配置,默认超时时间为6m
    object-live-to-time: 6
    #默认信息缓存配置,默认超时时间为30s
    default-live-to-time: 30

3.缓存配置类

@Configuration
@EnableCaching
public class RedisClusterConfigSpringboot2x extends CachingConfigurerSupport {
    @Autowired
    private Environment environment;
    @Bean
    CacheManager cacheManager(RedisConnectionFactory connectionFactory) {
        //结构化信息缓存配置,默认超时时间为2m
        RedisCacheConfiguration structServiceCache = ().entryTtl((("-live-to-time",))).disableCachingNullValues().prefixKeysWith("StructServiceCache");
        //对象化信息缓存配置,默认超时时间为6m
             RedisCacheConfiguration objectServiceCache = ().entryTtl((("-live-to-time",))).disableCachingNullValues().prefixKeysWith("ObjectServiceCache");
        Map<String, RedisCacheConfiguration> redisCacheConfigurationMap = new HashMap<>();
        ("StructServiceCache", structServiceCache);
        ("ObjectServiceCache", objectServiceCache);
        //初始化一个RedisCacheWriter
        RedisCacheWriter redisCacheWriter = (connectionFactory);


        //设置CacheManager的值序列化方式为JdkSerializationRedisSerializer,但其实RedisCacheConfiguration默认就是使用StringRedisSerializer序列化key，JdkSerializationRedisSerializer序列化value,所以以下注释代码为默认实现
        //ClassLoader loader = ().getClassLoader();
        //JdkSerializationRedisSerializer jdkSerializer = new JdkSerializationRedisSerializer(loader);
        //<Object> pair = (jdkSerializer);
        //RedisCacheConfiguration defaultCacheConfig=().serializeValuesWith(pair);


        RedisCacheConfiguration defaultCacheConfig = ();
        //设置默认超过期时间是30秒，这是设置的除了StructServiceCache和ObjectServiceCache的缓存容器的默认超时时间
        ((("-live-to-time",)));
        //初始化RedisCacheManager
        RedisCacheManager cacheManager = new RedisCacheManager(redisCacheWriter, defaultCacheConfig, redisCacheConfigurationMap);
        return cacheManager;
    }

4.接口调用缓存层

    @Cacheable(value = "StructServiceCache",key="#+#p0+#p1")
    public List<Map<String, Object>> getStructsByItems(String type, String item);

四、总结

springboot  和,在redis连接上有较大变动。是用的jedis连接池，而默认是用的lettuce.
