spring-boot - reactor/netty/resources/ConnectionProvider.fixed(Ljava/lang/String;IJLjava/time/Duration;)Lreactor/netty/resources/ConnectionProvider;

Question

Spring Boot 应用程序使用 Azure Cosmos DB 启动失败
描述:
试图调用不存在的方法。尝试是从以下位置进行的:

com.azure.cosmos.implementation.http.HttpClient.createFixed(HttpClient.java:56)

以下方法不存在:

reactor.netty.resources.ConnectionProvider.fixed(Ljava/lang/String;IJLjava/time/Duration;)Lreactor/netty/resources/ConnectionProvider;

该方法的类 reactor.netty.resources.ConnectionProvider 可从以下位置获得:

jar:file:/Users/vishnuvuyyur/.m2/repository/io/projectreactor/netty/reactor-netty-core/1.0.1/reactor-netty-core-1.0.1.jar!/reactor/netty/resources/ConnectionProvider.class

类层次结构是从以下位置加载的:

reactor.netty.resources.ConnectionProvider: file:/Users/vishnuvuyyur/.m2/repository/io/projectreactor/netty/reactor-netty-core/1.0.1/reactor-netty-core-1.0.1.jar

Answer 1

错误原因:

正如在日志中所说:com.azure.cosmos.implementation.http.HttpClient.createFixed(HttpClient.java:56)

azure cosmos 库没有用最新的spring boot 版本更新

当前问题可以通过 spring-boot 2.4.0 和 azure cosmos db 3.0.0-beta.1 重现

<groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.3.RELEASE</version>

 <dependency>
      <groupId>com.microsoft.azure</groupId>
      <artifactId>azure-cosmosdb-spring-boot-starter</artifactId>
  <version>3.0.0-beta.1</version> 

修复，由于 azure db 版本 3.0.0-beta.1 不支持 spring 2.4.0，因此将 spiring 启动版本降低到 2.3.5
