UnsatisfiedDependencyException when creating MongoTemplate bean

Question

Using the Mongobee for Migration with spring mongo

 plugins {
    id \'org.springframework.boot\' version \'2.3.1.RELEASE\'
    id \'io.spring.dependency-manageme         


        

Answer 1

It seems you don't have the bean created for "MongoTemplate"

Create a bean for it and use that to setMongoTemplate for Mongobee.

Below is the example to do so

@Bean
public MongoClient mongo() {
    return new MongoClient("localhost");
}

@Bean
public MongoTemplate mongoTemplate() throws Exception {
   return new MongoTemplate(mongo(), "test");
}

then use this

@Bean
public Mongobee mongobee(){
    logger.info("Starting product migration ...");
    String mongoUri = environment.getProperty("spring.data.mongodb.uri");
    boolean migrationsEnabled = Boolean.parseBoolean(environment.getProperty("app.db.migrations.enabled"));
    Mongobee runner = new Mongobee(mongoUri);
    runner.setEnabled(migrationsEnabled);
    runner.setChangeLogsScanPackage("fete.bird.fetebirdproduct.migration");
    runner.setChangelogCollectionName("migrations");
    runner.setLockCollectionName("migrations_lock");
    runner.setMongoTemplate(mongoTemplate());
    logger.info("Product migration completed...");
    return runner;
}

Now, you don't have to use constructor dependency and later wherever you want MongoTemplate you can use

 @Autowired  
 MongoTemplate mongoTemplate;

Hope, this will solve your problem !!
