《云原生机密计算最佳实践白皮书》——05编程框架——Apache Teaclave Java TEE SDK: 面向Java生态的机密计算编程框架——Apache_Teaclave_ Java_TEE_SDK 最佳实践（5）
4.5 管理服务实现(host)
在host子模块实现对enclave的管理与服务加载.
cd helloworld/host/src/main/java/com/sample/ mkdir -p helloworld/host
创建Main.java, 实现机密计算服务管理:
package com.sample.helloworld.host; import org.apache.teaclave.javasdk.host.Enclave; import org.apache.teaclave.javasdk.host.EnclaveFactory; import org.apache.teaclave.javasdk.host.EnclaveType; import com.sample.helloworld.common.Service; import java.util.Iterator; public class Main { public static void main(String[] args) throws Exception { EnclaveType[] enclaveTypes = { EnclaveType.MOCK_IN_JVM, EnclaveType.MOCK_IN_SVM, EnclaveType.TEE_SDK}; for (EnclaveType enclaveType : enclaveTypes) { Enclave enclave = EnclaveFactory.create(enclaveType); Iterator<Service> services = enclave.load(Service.class); System.out.println(services.next().sayHelloWorld()); enclave.destroy(); } } }
4.6 编译和运行
回到工程根目录并编译工程:
mvn -Pnative clean package
编译成功后, 运行该Demo:
$JAVA_HOME/bin/java -cp host/target/host-1.0-SNAPSHOT-jar-with dependencies.jar:enclave/target/enclave-1.0-SNAPSHOT-jar-with-dependencies.jar com. sample.helloworld.host.Main
