shiro use redis cache

Use shiro, ShiroConfig defined in the instance of the object securityManager:

@Bean
    public SecurityManager securityManager(MyShiroRealm myShiroRealm, RedissonWebSessionManager redissonWebSessionManager, RedissonShiroCacheManager redissonShiroCacheManager) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();

        // 自定义缓存实现 使用redis
        securityManager.setCacheManager(redissonShiroCacheManager);

        return securityManager;
    }

RedissonShiroCacheManager which is redis custom implement caching, redissonShiroCacheManager acquired cache objects getCache. Process describes cache data access target:
RedissonShiroCache <K, V> the implements the Cache <K, V>

@Override
    public V get(K key) throws CacheException {
        Object value = (RedissonShiroCache)this.map.get(key);   //获取缓存
    
        return fromStoreValue(value);
    }

this.map.get (key) acquires cache, wherein the map type is RMap <K, Object> map, when calling get () method will be called the implementation class RMap RedissonMap <K, V>:

public V get(Object key) {
        return this.get(this.getAsync(key));
    }

The following method is put, get the same manner as the above process:
RedissonShiroCache <K, V> the implements the Cache <K, V>

@Override
    public V put(K key, V value) throws CacheException {
       
         Object  previous = this.map.put(key, val, config.getTTL(), TimeUnit.MILLISECONDS,
                    config.getMaxIdleTime(), TimeUnit.MILLISECONDS);
        
        return fromStoreValue(previous);
    }

RedissonMap<K, V>

  public V put(K key, V value) {
        return this.get(this.putAsync(key, value));
    }
