使用cosmosdb spring boot starter的示例spring boot应用程序无法使用输入字节数组启动，在88处有不正确的结束字节

Question

我试图使用cosmos DB文档API制作一个简单的Spring Boot应用程序（表API也是一个选项）

遵循此示例并使用本地仿真器

Spring启动2.3 AzureSpring启动：2.3.1

应用程序无法引导，原因是：

    at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:185) ~[spring-beans-5.2.6.RELEASE.jar:5.2.6.RELEASE]
    at org.springframework.beans.factory.support.ConstructorResolver.instantiate(ConstructorResolver.java:651) ~[spring-beans-5.2.6.RELEASE.jar:5.2.6.RELEASE]

这里是一个用于复制错误的存储库，位于主配置文件下面：

@Slf4j
@Configuration
@EnableCosmosRepositories
public class CosmosConfiguration extends AbstractCosmosConfiguration {

    @Value("${azure.cosmosdb.uri}")
    private String uri;

    @Value("${azure.cosmosdb.key}")
    private String key;

    @Value("${azure.cosmosdb.secondaryKey}")
    private String secondaryKey;

    @Value("${azure.cosmosdb.database}")
    private String dbName;

    @Value("${azure.cosmosdb.populateQueryMetrics}")
    private boolean populateQueryMetrics;

    private CosmosKeyCredential cosmosKeyCredential;

    private static class ResponseDiagnosticsProcessorImplementation implements ResponseDiagnosticsProcessor {

        @Override
        public void processResponseDiagnostics(@Nullable ResponseDiagnostics responseDiagnostics) {
            log.info("Response Diagnostics {}", responseDiagnostics);
        }
    }

    @Bean
    @Primary
    public CosmosDBConfig getConfig() {
        this.cosmosKeyCredential = new CosmosKeyCredential(key);
        CosmosDBConfig cosmosdbConfig = CosmosDBConfig.builder(uri, this.cosmosKeyCredential, dbName).build();
        cosmosdbConfig.setPopulateQueryMetrics(populateQueryMetrics);
        cosmosdbConfig.setResponseDiagnosticsProcessor(new ResponseDiagnosticsProcessorImplementation());
        return cosmosdbConfig;
    }

    public void switchToSecondaryKey() {
        this.cosmosKeyCredential.key(secondaryKey);
    }
}

豆：

@Builder
@AllArgsConstructor
@Data
@Document
//@Document(collection = "testCosmos")
public class Entity {

    @Id
    @PartitionKey
    private String id;

    private String value;
}

存储库（我不想使用被动存储库）：

@Repository
    public interface SimpleRepository extends CosmosRepository<Entity, String> {
}

您对它无法启动的原因有什么建议吗？如果我不定义自定义的cosmos配置类，结果不会改变

我不使用反应式存储库，因为我想在现有的jpa应用程序中使用cosmos，而webflow对jpa不满意。

Azure Cosmos DB的Spring数据不能用于表API。它只能与SQL API一起使用。
