问题
I am trying to configure Google Cloud Datastore API with Spring Boot in order to deploy it on Compute Engine. When I try to run the Spring Boot project locally, I keep on getting the following error
org.apache.catalina.core.ContainerBase : A child container failed during start
Problem I built a demo project using Spring Initizr (http://start.spring.io/) and added the maven dependency for Google Cloud Datastore API as following
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>gcloud-java-datastore</artifactId>
<version>0.2.0</version>
</dependency>
I am able to build the project but when I run the project it fails to start the embedded Tomcat. Spring Boot works fine, as soon as I remove the Google Cloud Datastore dependency.

回答1:
Finally managed to fix it by excluding the servlet-api. Changed the pom.xml file as following
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>gcloud-java</artifactId>
<version>0.2.1</version>
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
</exclusion>
</exclusions>
</dependency>
回答2:
Did you create a WebMvcConfiguration class?
Try this:
@Configuration
public class MyMVCConfiguration extends WebMvcConfigurerAdapter {
// Implements overrides methods.
}
And declare in your void main your configuration package:
@Configuration
@EnableAutoConfiguration
@ComponentScan({"com.yourpackegconfiguration"})
public class LauncherWebWS {
public static void main(String[] args) {
SpringApplication.run(LauncherWebWS.class, args);
}
}
