Conflicts between MongoDB and JPA [DATAMONGO-403]

[spring-projects-issues]

Marty Pitt opened DATAMONGO-403 and commented

I have a project that combines both MongoDB and JPA persistence strategies, so uses both of the associated projects.

After upgrading versions, I've found series of exceptions thrown.

Initially I was using:

<properties>
  <spring.data.jpa.version> 1.1.0.BUILD-SNAPSHOT</spring.data.jpa.version>
  <spring.data.mongo.version>1.0.0.RC1</spring.data.mongo.version>
  <query.dsl.version>2.3.0</query.dsl.version>
</properties>

However, I'm assuming the snapshot has changed, because this is now throwing an excepition:

java.lang.NoClassDefFoundError: org/springframework/data/mapping/model/SpELAwareParameterValueProvider

I then upgraded to the following:

<properties>
  <spring.data.jpa.version>1.1.0.RC1</spring.data.jpa.version>
  <spring.data.mongo.version>1.0.1.RELEASE</spring.data.mongo.version>
  <query.dsl.version>2.3.0</query.dsl.version>
</properties>

Which rendered the following exception:

java.lang.NoSuchMethodError: org.springframework.data.mongodb.core.mapping.MongoPersistentEntity.getPreferredConstructor()Lorg/springframework/data/mapping/PreferredConstructor;
	at org.springframework.data.mongodb.core.convert.MappedConstructor.<init>(MappedConstructor.java:56)
	at org.springframework.data.mongodb.core.convert.MappingMongoConverter.read(MappingMongoConverter.java:212)
	at org.springframework.data.mongodb.core.convert.MappingMongoConverter.read(MappingMongoConverter.java:200)
	at org.springframework.data.mongodb.core.convert.MappingMongoConverter.read(MappingMongoConverter.java:164)
	at org.springframework.data.mongodb.core.convert.MappingMongoConverter.read(MappingMongoConverter.java:73)
…

After further investigation, it appears the conflict is in the dependency versions of spring-data-commons-core

• spring-data-jpa:1.1.0.RC1 -> spring-data-commons-core:1.3.0.BUILD-SNAPSHOT
• spring-data-mongodb:1.0.1.RELEASE -> spring-data-commons-core:1.2.1.RELEASE

I then tried the following:

<properties>
  <spring.data.jpa.version>1.1.0.RC1</spring.data.jpa.version>
  <spring.data.mongo.version>1.1.0.BUILD-SNAPSHOT</spring.data.mongo.version>
  <query.dsl.version>2.3.0</query.dsl.version>
</properties>

Which resulted in a NullPointerException, as follows:

As it stands, there doesn't appear to be a working combination of JPA/MongoDB/Core that is usable

I can confirm this bug report. I have exactly the same configuration, and I'm getting exactly the same stack trace. I simply saved something in MongoDB using the generated Repository and then got the exception when trying to retrieve it. I am using the latest SNAPSHOT.

I'm not sure I would concluded that it is the mix of JPA and MongoDB that is the source of the problem, just yet. If I get a chance, I'll try removing my JPA configuration and report back on the result

Any chance of some feedback from Oliver / team?

Long story short: currently you cannot use MongoDB and JPA together. This is due to some breaking changes required in versions 1.2 of Spring Data Commons which we needed to introduce due to the long time between the JPA GA release and MongoDBs GA release. Here's what we're doing about it:

1. As of the next milestone versions (SD JPA 1.1RC1 (already released), SD MongoDB 1.1M1 (coming), SD Neo4j 2.1M1 (coming)) all version will depend on Spring Data Commons 1.3 (currently in M1)
2. We'll have a multi-store project in place that will allow to check the compatibility of versions and allows looking up how to configure snapshot versions, milestone versions or releases in combination with Spring 3.0.x or 3.1.x.

For now the stores should work fine in combination if you're using the snapshot versions. I'll set the fix for M1 of MongoDB as this will be the first released version working with other milestones

I must be doing something wrong. I managed to work on something else for a bit, but I have now returned to the code that is affected by this bug, and I'm still getting the same NPE, and the same stack trace with the line numbers bumped a bit. I'm using the latest SNAP-SHOT builds.

Any ideas?
Thanks!

I dont think this is a conflict with MongoDB and JPA. I think its an issue using the Spring Data Repositories with MongoDB. I get a similar exception by just trying to read from mongo without having JPA involved.

<!-- only explicit dep -->
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>1.1.0.M1</version>
</dependency>

Simple Mongo setup following repository method outlined in docs for 1.1. Doing repository.save(SOME_OBJECT) works. However, when trying to read anything [even repository.count() ]:

Nevermind - stupid user error. It turns out I had misspelled one of my c'tor args by 1 character. The error message in version 1.1.M1...is obtuse. Switching back to version 1.0.1...the error message clearly says "you screwed up, there is no property named X in the your object" (or something similar)
