§ 查看依赖类：protobuf，发现其中无方法LiteralByteString：
Maven查看到我们依赖的protobuf版本为：3.14.0，他源自我们pom中导入的hbase-server 1.3.11
尝试降低hbase-server的版本，2.6.1及以下的protobuf-java是有LiteralByteString的 <!--HBase服务器依赖--> <dependency> <groupId>org.apache.hbase</groupId> <artifactId>hbase-server</artifactId> <version>1.3.1</version> <!--hbase-server依赖的protobuf-java版本过高，会导致报错：NoClassDefFoundError: com/google/protobuf/LiteralByteString--> <exclusions> <exclusion> <artifactId>protobuf-java</artifactId> <groupId>com.google.protobuf</groupId> </exclusion> </exclusions> </dependency> <!--HBase客户端依赖--> <dependency> <groupId>org.apache.hbase</groupId> <artifactId>hbase-client</artifactId> <version>1.3.1</version> <exclusions> <exclusion> <artifactId>protobuf-java</artifactId> <groupId>com.google.protobuf</groupId> </exclusion> </exclusions> </dependency> <!-- 手动导入低版本的protobuf-java依赖 --> <dependency> <groupId>com.google.protobuf</groupId> <artifactId>protobuf-java</artifactId> <version>2.6.1</version> </dependency>

查看protobuf类
重新测试，通过
