Doing the constructor dependency for MongoTemplate causing the error org.springframework.beans.factory.UnsatisfiedDependencyException:Error creating bean with name 'mongoTemplate'
Here is the configuration code
@Configuration
public class ProductMigration {
private final Environment environment;
private MongoTemplate mongoTemplate;
private static final Logger logger = LoggerFactory.getLogger(FeteBirdProductApplication.class);
public ProductMigration(Environment environment, MongoTemplate mongoTemplate) {
this.environment = environment;
this.mongoTemplate = mongoTemplate;
}
@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(this.mongoTemplate);
logger.info("Product migration completed...");
return runner;
}
}
The issue is caused by constructor dependency for MongoTemplate, but don't know how to solve the issue,
I tried @Autowired, didn't work same issue.

回答1:
The version of Spring Data MongoDB included in Spring Boot 2.3 uses version 4 of Mongo's Driver, but Mongobee depends on version 3. The two versions have different Maven coordinates (group ID and artifact ID) so you end up with both of them on the classpath. This leads to some code from version 4 of the driver using code from version 3 and a NoSuchFieldError results.
You can avoid the problem by excluding the Mongo Driver from the Mongobee dependency:
compile('com.github.mongobee:mongobee:0.13') {
exclude group: 'org.mongodb'
}
回答2:
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 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 !!
回答3:
Here it is,
@Bean
public MongoClient mongo() {
return new MongoClient("localhost");
}
回答4:
mongobee was written using version 3 of the Mongo Java libraries, which has a number of incompatibilities with version 4, including the one you are running across. By all indications, mongobee has been abandoned by its creators, with the last commit being made in March, 2018, and no responses to issues by the creators since then.
Due to this project abandonment, several successor libraries have since been forked from mongobee. Two of the successor libraries, Mongock and mongobeeJ, currently support or will soon support version 4 of the Mongo Java libraries.
mongobeeJ is a direct continuation of mongobee, with three releases. Support for version 4 of the Mongo Java driver was recently implemented but not yet released as of August 10, 2020 (mongobeeJ#3).
Mongock is a significant evolution of Mongobee, with built-in support for migrating from mongobee. It has built-in support for version 4 of the Mongo Java driver, as well as for Spring & Spring Boot (which I notice from your list of dependencies that you are using).
Therefore, if you wish to use mongobee with version 4 of the Mongo Java library and don't wish to modify the library yourself, using one of these public forks is the way to go.
