    • SimpleCache

      public SimpleCache(Properties properties)
      Constructs a new SimpleCache with the given properties. The properties are used to configure the underlying MyBatis cache, including its type, eviction policy, and size.
      Parameters:
      properties - the properties for configuring the cache

  • Method Details

    • read

      public V read(K key)
      Reads a value from the cache associated with the given key.
      Specified by:
      read in interface org.miaixz.bus.cache.CacheX<K,V>
      Parameters:
      key - the key whose associated value is to be returned
      Returns:
      the value to which the specified key is mapped, or null if this cache contains no mapping for the key

    • read

      public Map<K,V> read(Collection<K> keys)
      Reads multiple values from the cache associated with the given keys. This implementation returns an empty map as it's not directly supported by the underlying MyBatis cache.
      Specified by:
      read in interface org.miaixz.bus.cache.CacheX<K,V>
      Parameters:
      keys - a collection of keys for which to retrieve values
      Returns:
      an empty map

    • write

      public void write(K key, V value, long expire)
      Writes a key-value pair to the cache with a specified expiration time. The expiration time is not directly used by the underlying MyBatis cache, which is configured via properties.
      Specified by:
      write in interface org.miaixz.bus.cache.CacheX<K,V>
      Parameters:
      key - the key with which the specified value is to be associated
      value - the value to be associated with the specified key
      expire - the expiration time in milliseconds (not directly used by this implementation)

    • write

      public void write(Map<K,V> map, long expire)
      Writes multiple key-value pairs to the cache with a specified expiration time. This implementation does nothing as it's not directly supported by the underlying MyBatis cache.
      Specified by:
      write in interface org.miaixz.bus.cache.CacheX<K,V>
      Parameters:
      map - a map of key-value pairs to be stored in the cache
      expire - the expiration time in milliseconds (not directly used by this implementation)

    • remove

      public void remove(K... keys)
      Removes the specified keys from the cache. This implementation does nothing as it's not directly supported by the underlying MyBatis cache.
      Specified by:
      remove in interface org.miaixz.bus.cache.CacheX<K,V>
      Parameters:
      keys - an array of keys to be removed from the cache

    • clear

      public void clear()
      Clears all entries from the cache. This implementation does nothing as it's not directly supported by the underlying MyBatis cache.
      Specified by:
      clear in interface org.miaixz.bus.cache.CacheX<K,V>
