+# 使用native-image
+   Redkale支持GraalVM的native-image， 由于Redkale使用了大量的asm动态生成代码，而native-image不支持动态字节码，因此需要使用```redkale-maven-plugin```执行预编译，提前生成动态字节码进行打包。
+
+## 安装GraalVM
+```
+  下载地址: https://www.graalvm.org/downloads/
+```
+
+## 安装native-image
+```
+  install native-image
+```
+
+## 配置pom
+```xml
+    <plugin>
+        <groupId>org.redkale.maven.plugins</groupId>
+        <artifactId>redkale-maven-plugin</artifactId>
+        <version>1.2.0</version>
