无法使用GAE运行Spring Boot单元测试
[英]Can't run spring boot unit tests with GAE
问题描述
Every time I try and run unit tests for my Google App Engine with Spring Boot project I get setup errors and I cannot seem to find a solution. 
每次尝试使用Spring Boot项目为Google App Engine运行单元测试时，都会出现安装错误，而且似乎找不到解决方案。
Here is my current error: 这是我当前的错误：

Evidently you need Servlet 3.1 (credit to chrylis ). 显然，您需要Servlet 3.1（提供给chrylis ）。 However, GAE only supports up to 2.5. 但是，GAE仅支持2.5。 So I have changed my pom.xml to switch between the two depending on profile. 因此，我已经更改了pom.xml，以根据配置文件在两者之间切换。
Furthermore I couldn't get the tests to work with jetty (which GAE uses for its local dev server) so I also switch to tomcat for the tests. 此外，我无法使测试与码头（GAE用于其本地开发服务器的码头）一起使用，因此我也切换到了tomcat进行测试。
