While trying to run Spring-boot application (v2.1.0) getting below error:

Description:

An attempt was made to call the method org.springframework.data.mongodb.core.MongoTemplate.(Lcom/mongodb/Mongo;Ljava/lang/String;)V but it does not exist. Its class, org.springframework.data.mongodb.core.MongoTemplate, is available from the following locations:

file:/C:/Users/npatil/.m2/repository/org/springframework/data/spring-data-mongodb/2.1.2.RELEASE/spring-data-mongodb-2.1.2.RELEASE.jar!/org/springframework/data/mongodb/core/MongoTemplate.class

It was loaded from the following location:

file:/C:/Users/npatil/.m2/repository/org/springframework/data/spring-data-mongodb/2.1.2.RELEASE/spring-data-mongodb-2.1.2.RELEASE.jar

Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.data.mongodb.core.MongoTemplate

Below is a snnipet from my pom:

<dependencies>
.
.
  <dependency>
    <groupId>com.github.mongobee</groupId>
    <artifactId>mongobee</artifactId>
    <version>0.13</version>
  </dependency>
  <dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-mongodb</artifactId>
    <version>2.1.2.RELEASE</version>
  </dependency>
.
.
</dependencies>

Version of some of the jars that could help are:
spring-data-mongodb : 2.1.2.RELEASE
spring-web : 5.1.2.RELEASE
mongo-java-driver : 3.8.2.RELEASE

Deleted .m2 and did mvn clean install, but even that did not resolve the issue. Any help would be greatly appreciated.

  • Try with `Spring Boot 2.0.0.RELEASE` – TheSprinter Dec 03 '18 at 12:02
  • din't work :( Any specific reason for making it to `2.0.0`? – Nisarg Patil Dec 03 '18 at 12:27
  • There was nothing to do with the boot version. There is a call to constructor `new MongoTemplate(MongoClient mongoClient, String databaseName)`, when I ctrl-click on it, it goes to `Object` class. This was perhaps some issues with loading of `jars`. – Nisarg Patil Dec 10 '18 at 16:28

Looks like jar is corrupted or missing, check all spring related jar are 4.x or higher version if that doent work then:
Mongobee depends on Spring 4.x jars which may conflicts with Spring boot 2.x

try the below way

  @Bean
  public Mongobee mongobee(){
    Mongobee mongobee = new Mongobee("mongodb://localhost:27017/seed");
    mongobee.setChangeLogsScanPackage(InitialData.class.getPackageName());
            mongobee.setMongoTemplate(template);

    return mongobee;
  }

You need change Mongobee by Mongock if you use Springboot 2. The syntax is almost the same because the Mongock project is the continuation of the Mongobee project.

Springboot:

@Bean
public SpringBootMongock mongock(ApplicationContext springContext, MongoClient mongoClient) {
  return (SpringBootMongock) new SpringBootMongockBuilder(mongoClient, "yourDbName", "com.package.to.be.scanned.for.changesets")
      .setApplicationContext(springContext) 
      .setLockQuickConfig()
      .build();
}

Spring:

@Bean
public SpringMongock mongock() {
  MongoClient mongoclient = new MongoClient(new MongoClientURI("yourDbName", yourMongoClientBuilder));
  return new SpringMongockBuilder(mongoclient, "yourDbName", "com.package.to.be.scanned.for.changesets")
      .setLockQuickConfig()
      .build();
}
