Can't connect to Bigtable from a Spring Boot application

问题

I have a standalone application that works fine with Bigtable when creating a connection like this:

Connection connection = BigtableConfiguration.connect(PROJECT_ID, INSTANCE_ID)

and using the following dependencies:

<dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-storage</artifactId>
    <version>v1-rev78-1.22.0</version>
</dependency>
<dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-pubsub</artifactId>
    <version>v1-rev11-1.22.0</version>
</dependency>
<dependency>
    <groupId>com.google.cloud.bigtable</groupId>
    <artifactId>bigtable-hbase-1.2</artifactId>
    <version>0.9.5</version>
</dependency>
<dependency>
    <groupId>org.apache.hbase</groupId>
    <artifactId>hbase-client</artifactId>
    <version>1.2.4</version>
</dependency>
<dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-tcnative-boringssl-static</artifactId>
    <version>1.1.33.Fork26</version>
</dependency>

I'm converting it now to a Spring Boot web application, so I had to add this dependency:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>1.4.2.RELEASE</version>
</dependency>

I haven't changed anything else at all, just added these 5 lines and now I'm getting this error:

回答1:

The libraries used to connect to Bigtable seem to have some kind of conflict with the Tomcat libraries used by Spring Boot by default.

Use Jetty instead of Tomcat as a workaround.

Also, com.google.protobuf:protobuf-java went missing after this transition, so don't forget to add it too.

This is how you replace Tomcat for Jetty in Spring Boot:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jetty</artifactId>
</dependency>
<!-- Excluding spring-boot-starter-tomcat from Spring Boot and adding spring-boot-starter-jetty
made protobuf-java disappear although it's still needed -->
<dependency>
    <groupId>com.google.protobuf</groupId>
    <artifactId>protobuf-java</artifactId>
    <version>3.1.0</version>
</dependency>
