Migrating Spring Boot 1.5 to 2.7 and facing issues in MongoDB

[aakash03chaudhari]

What problem are you trying to solve?

We attempted to migrate our project from Spring Boot 1.5 to 2.7. Our current project uses MongoDB, but the MongoDB code has not been fully migrated. For example:

The following:

public BulkWriteOperation bulkLoader;
public BulkWriteOperation bulkLoaderForBreakendInfo;

should be converted to:

public BulkOperations bulkLoader;
public BulkOperations bulkLoaderForBreakendInfo;

2. BasicDBObject should be converted to Document.

To facilitate the migration, we added the OpenRewrite plugins to our pom.xml and ran the recipe using mvn rewrite:run.

Here's the relevant part of our pom.xml:

org.openrewrite.maven rewrite-maven-plugin 5.34.0 org.openrewrite.java.spring.boot2.UpgradeSpringBoot_2_7 org.openrewrite.recipe rewrite-spring 5.13.2

Thanks for logging an issue! I think it should be fairly easy to cover these cases, if all we have to do is change those types. YOu can see an example here:

rewrite-spring/src/main/resources/META-INF/rewrite/springdoc.yml

Lines 52 to 54 in d49e38e

	- org.openrewrite.java.ChangeType:
	oldFullyQualifiedTypeName: org.springdoc.core.SpringDocUtils
	newFullyQualifiedTypeName: org.springdoc.core.utils.SpringDocUtils

In this case we'll want to work out what version of Spring Boot necessitates the change, and then add that change to the corresponding yml file under https://github.com/openrewrite/rewrite-spring/tree/d49e38ed41300f6234cabc9794fce3959912f894/src/main/resources/META-INF/rewrite

Would love it if you're open to contribute that change. Even a draft PR would help kick this off and get it included in next week's release.

Hi @aakash03chaudhari
For BulkWriteOperation, BulkOperations, and BasicDBObject
Could you please help me with the package name for the above and if any other packages you need recipes, I will help you with the recipe.

Is BulkWriteOperation comes with com.mongodb.BulkWriteOperation?

Thanks,
Mahi
