spring boot application starts up fails with Azure cosmos DB

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

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

The following method did not exist:

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

The method's class, reactor.netty.resources.ConnectionProvider, is available from the following locations:

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

The class hierarchy was loaded from the following locations:

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

Reason for the error:

  • As in the logs it states :com.azure.cosmos.implementation.http.HttpClient.createFixed(HttpClient.java:56)

  • The azure cosmos library is not updated with the latest spring boot version

  • Current issue can be reproduced with spring-boot 2.4.0 and azure cosmos db 3.0.0-beta.1

    <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>

  • Fix, lower the spiring boot version to 2.3.5 since azure db version 3.0.0-beta.1 dosen't support spring 2.4.0

Changing the spring boot version worked for me

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.4.RELEASE</version>
    <relativePath/>
