如何部署对Google的春季战AppEngine - Java11
我正在尝试部署一个war打包的springboot应用程序- Java 11。
创建了一个全新的springboot web应用程序(打包war)，并遵循了https://cloud.google.com/appengine/docs/standard/java-gen2/war-packaging来自step1的文章。即克隆和安装(https://github.com/GoogleCloudPlatform/java-docs-samples)

遗憾的是，这不是我所期望的。
另一个变体:我记得的没有添加servlet初始化器，所以纠正它
@SpringBootApplication
public class DashApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.runDashApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DashApplication.class);
}
}误差
应用程序在日志中出现错误。
org.springframework.boot.env.EnvironmentPostProcessor org.springframework.boot.test.web.SpringBootTestRandomPortEnvironmentPostProcessor "java.lang.IllegalArgumentException:无法实例化org.springframework.boot.util.Instantiator.instantiate(Instantiator.java:131) at java.base/java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:195)
我犯了什么错？
请帮助-如何创建一个简单的Java 11，springboot引导，war包，并部署到应用程序引擎

正如注释部分所提到的，在spring-boot-starter-test中添加pom.xml作为测试依赖解决了这个问题。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
</dependency>为了将来可能遇到这个用例的社区的利益，将答案作为社区wiki发布。
