适用版本:v3.2.0+;

配置j2cache配置文件

  • caffeine.properties

示例:

default = 1000, 30m

ibps.context = 10000, 10m

ibps.sys = 10000, 1h

#
上面的配置定义了三个缓存 Region ,分别是:

默认缓存,大小是 1000 个对象,TTL 是 30 分钟
ibps.context 缓存,大小是 10000 个对象,TTL 是 10 分钟
ibps.sys 缓存,大小是 10000 个对象,TTL 是 1 个小时

default 是当我们调用如下方法时:

public void set(String region, String key, Object value)

如果我们传入的 region 参数(假设为:region1)没有在 caffeine.properties 中定义的话,那 J2Cache 会自动创建一个名为 region1 的缓存 Region,其配置和 default 的配置一致。
  • j2cache.properties

示例:

# 缓存广播方法,支持 jgroups/redis/lettuce/rabbitmq/rocketmq
j2cache.broadcast = lettuce

# 第一二级缓存实现方式,一级支持 ehcache/caffeine, 二级支持 redis/lettuce/memcached
j2cache.L1.provider_class = caffeine
j2cache.L2.provider_class = lettuce

# 在redis缓存数据中启用/禁用ttl(如果禁用,redis中的对象将永远不会过期,默认值:true)
j2cache.sync_ttl_to_redis = true

# 默认情况下是否缓存空对象(默认为false)
j2cache.default_cache_null_object = true

# 缓存序列化方式,支持 fst/kryo/fastjson/java/json/fse
j2cache.serialization = kryo

# caffeine配置文件
caffeine.properties = /config/caffeine.properties

# 缓存名称空间可选,默认为[空]
# redis存储模式 支持 generic/hash
# 发布/订阅频道名称
lettuce.namespace =
lettuce.storage = generic
lettuce.channel = j2cache.platform

lettuce.channel = j2cache.platform 需要注意,不同的服务名称需要唯一

重写仓库、领域中cache相关方法

DefaultPartyUser的仓库和领域类为例子

仓库
  • getInternalCacheName()
    public String getInternalCacheName() {
        return CacheKeyConstants.Region.REGION_IBPS_PARTY; // 返回对应的region名称
    }
  • getInternalType()
    public String getInternalType() {
        return "DefaultPartyUser"; // 返回对应的类型名称,一般为类的名称即可
    }
  • getInternal(P p)
    public void getInternal(DefaultPartyUserPo p) {
        if(BeanUtils.isEmpty(p)) {
            return;
        }
        // 跳过一级缓存
        partyEmployeeRepository.setSkipInternal();
        PartyEmployeePo employeePo = partyEmployeeRepository.get(p.getId());
        // 恢复一级缓存
        partyEmployeeRepository.removeSkipInternal();
        if(BeanUtils.isEmpty(employeePo)) {
            return;
        }

        p.setFullname(employeePo.getName());
        p.setName(employeePo.getName());
        p.setStatus(employeePo.getStatus());
        p.setGender(employeePo.getGender());

        p.setQq(employeePo.getQq());
        p.setPhoto(employeePo.getPhoto());
        p.setWcAccount(employeePo.getWcAccount());
