aria-label="Direct link to GraalVM Native Image" title="Direct link to GraalVM Native Image" translate=no></a></h2> |
| <p>GraalVM <code>native image</code> compiles Java code into native executables ahead-of-time, resulting in faster startup and lower memory usage. However, native images don't support runtime JIT compilation or reflection without explicit configuration.</p> |
| <p>Apache Fory™ works excellently with GraalVM native image by using <strong>codegen instead of reflection</strong>. All serializer code is generated at build time, eliminating the need for reflection configuration files in most cases.</p> |
| <h2 class="anchor anchorTargetStickyNavbar_Vzrq" id=how-it-works>How It Works<a href=#how-it-works class=hash-link aria-label="Direct link to How It Works" title="Direct link to How It Works" translate=no></a></h2> |
| <p>Fory generates serialization code at GraalVM build time when you:</p> |
| <ol> |
| <li class="">Create Fory as a <strong>static</strong> field</li> |
| <li class=""><strong>Register</strong> all classes in a static initializer</li> |
| <li class="">Call <code>fory.ensureSerializersCompiled()</code> to compile serializers</li> |
| <li class="">Configure the class to initialize at build time via <code>native-image.properties</code></li> |
| </ol> |
| <p><strong>The main benefit</strong>: You don't need to configure <a href=https://www.graalvm.org/latest/reference-manual/native-image/metadata/#specifying-reflection-metadata-in-json target=_blank rel="noopener noreferrer" class="">reflection json</a> or <a href=https://www.graalvm.org/latest/reference-manual/native-image/metadata/#serialization target=_blank rel="noopener noreferrer" class="">serialization json</a> for most serializable classes.</p> |
| <p>Note: Fory's <code>asyncCompilationEnabled</code> option is automatically disabled for GraalVM native image since runtime JIT is not supported.</p> |
