无法从 Spring Boot 应用程序连接到 Bigtable

分类: 技术问答 • 2022-04-06 11:54:10
问题描述：

我有一个独立的应用程序，可以在创建这样的连接时与 Bigtable 一起正常工作:

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

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:

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>

我根本没有更改任何其他内容，只添加了这 5 行，现在出现此错误:

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

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.

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

使用 Jetty 而不是 Tomcat 作为解决方法.

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

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

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

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>
