我试图制作spring-boot-legacy：1.0.1.RELEASE＆amp; spring-boot-starter-parent：1.1.8.RELEASE，GAE 1.9.19。但是，在通过mvn appengine：devserver运行时，我收到以下错误，阻止应用程序运行：

据我所知，Spring使用反射来自动连接依赖项，但似乎java.lang.reflect包中的某些类受到限制。关于如何使这项工作的任何想法？
答案 0 :(得分：3)
java.lang.reflect.Parameter。所以你必须降级到Java 7才能避免它。另一个原因是Google Appengine不支持Java 8，只支持Java 7.所以无论如何你都需要它。

查看迁移指南 https://cloud.google.com/appengine/docs/standard/java/migrating-to-java8
将add <runtime>java8</runtime>添加到appengine-web.xml
