我正在尝试构建自己的faas服务。我想支持在运行时加载函数。
@SpringBootApplication
@EnableScheduling
public class DeployerApplication {
FunctionCatalog catalog;
@Scheduled(cron = "0/5 * * * * ?")
void loadSomething() {
String[] args = new String[]{
"--spring.cloud.function.location=./faas-function/target/faas-function-1.0-SNAPSHOT-boot.jar",
"--spring.cloud.function.function-class=com.example.Tmp"};
ApplicationContext context = SpringApplication.run(TmpApplication.class, args);
catalog = context.getBean(FunctionCatalog.class);
}
public static void main(String[] args) {
SpringApplication.run(DeployerApplication.class, args);
}
@SpringBootApplication(proxyBeanMethods = false)
private static class TmpApplication {
}
}
但当我运行这些代码时，我得到了

spring-cloud函数部署器如何在运行时部署/取消部署函数？
你的问题很宽泛，所以。项目git存储库中有一个集成测试用例，以及演示几个受支持场景的单个项目(我相信你会找到适合你的(，请看一看，并随时提出更具体的问题。
