从java中调用webassembly函数
existism插件框架套件刚刚发布了他们最初的 java 支持。
使用@extism 插件库中的java host-sdk，您现在可以在基于jvm 的应用程序中运行webassembly。
可以点击标题找到文档和示例。
对于 Maven，添加到您的pom.xml：
<dependency>
<groupId>org.extism.sdk</groupId>
<artifactId>extism</artifactId>
<version>0.1.0</version>
</dependency>
package example;
import org.extism.sdk.Context;
import org.extism.sdk.manifest.Manifest;
import org.extism.sdk.wasm.WasmSourceResolver;
import java.nio.file.Path;
public class App
{
public static void main(String[] args)
{
var resolver = new WasmSourceResolver();
var manifest = new Manifest(resolver.resolve(Path.of("./code.wasm")));
try (var ctx = new Context(); var plugin = ctx.newPlugin(manifest, false))
{
var output = plugin.call("count_vowels", "Hello World");
System.out.println(output);
}
}
}

在这个例子中code.wasm是我们计算元音的示例插件。如果你想运行这个，先下载它并设置路径：
curl https://raw.githubusercontent.com/extism/extism/main/wasm/code.wasm > code.wasm |
运行Java应用输出：
{"count": 3}
