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);
   }
}
