java - 无法从 Spring Boot 应用程序连接到 Bigtable

Question

我有一个独立的应用程序，在创建如下连接时可以与 Bigtable 正常工作:

Connection connection = BigtableConfiguration.connect(PROJECT_ID, INSTANCE_ID)

并使用以下依赖项:

<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>

我现在将其转换为 Spring Boot Web 应用程序，因此我必须添加此依赖项:

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

我根本没有更改任何其他内容，只是添加了这 5 行，现在我收到此错误:

用于连接 Bigtable 的库似乎与 Spring Boot 默认使用的 Tomcat 库存在某种冲突。

使用 Jetty 而不是 Tomcat 作为解决方法。

com.google.protobuf:protobuf-java 在此转换后丢失了，所以不要忘记添加它

这是在 Spring Boot 中将 Tomcat 替换为 Jetty 的方法:

<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>
