# Configuration

**This is the manual for older MicroStream versions (Version < 5.0).**

The default way to configure a JCache provider is to use the class`javax.cache.configuration.MutableConfiguration`. This is mostly used to avoid provider specific code.

If you want to use all of MicroStream's Cache features, you can use our configuration implementation: `one.microstream.cache.CacheConfiguration`&#x20;

```java
CachingProvider provider     = Caching.getCachingProvider();  
CacheManager    cacheManager = provider.getCacheManager();   
CacheConfiguration<Integer, String> configuration = CacheConfiguration
			.Builder(Integer.class, String.class)
			.storeByValue()
			.expiryPolicyFactory(CreatedExpiryPolicy.factoryOf(Duration.ONE_MINUTE))
			.build(); 
Cache<Integer, String> cache = cacheManager.createCache("jCache", configuration); 
cache.put(1, "Hello World"); 
String value = cache.get(1); 
```

To read an external configuration use `CacheConfigurationLoader` and `CacheConfigurationParser` or the `Load*()` methods of `CacheConfiguration`.

```java
CacheConfiguration<Integer, String> configuration = CacheConfiguration
			.Load("cache-config.properties", Integer.class, String.class);
```

&#x20;If you just use `CacheConfiguration.Load()` the default configuration file is used, which is either a file in the classpath root named `microstream-cache.properties`, or the path configured via the system property `microstream.cache.configuration.path`.
