Auditing exception when nested entities in collection type filed have audit fields [DATACMNS-1519]

[spring-projects-issues]

revivn opened DATACMNS-1519 and commented

Hi. I'm trying to add auto auditing into spring project using spring-data-commons,spring-data-mongodb,both version 2.1.3.RELEASE

1. Enable mongo auditing in my spring project's mongodbConfig by using @EnableMongoAuditing.
2. Add an abstract entity(AbstractEntity) with @CreatedDate, @LastModifiedDate, @CreatedBy, and @LastModifiedBy annotations.
3. Add a sub object(EntityB) extends AbstractEntity,EntityB also have other ordinary fields.
4. Add another object(EntityA) extends AbstractEntity,EntityA have other ordinary fields and a collection filed type of List<EntityB>
5. Try saving EntityA's instance with collection filed type of List<EntityB> contains some EntityB's instance by calling the MongoRepository's save() method.
6. The error(java.lang.IllegalArgumentException) should display(Target bean of type java.util.ArrayList is not of type of the persistent entity (EntityB)!: java.util.ArrayList).

here's the data structure

I found that method

line:56  setProperty(..)

in

PersistentPropertyAccessor

may have defect in this nested collection field scenario:

line:64 Object parent = parentPath.isEmpty() ? getBean() : getProperty(parentPath)

while object "parent" get the collection type of List<EntityB>

line:74 PersistentPropertyAccessor<?> accessor = parent == getBean() //
 ? this //
 : leafProperty.getOwner().getPropertyAccessor(parent);

1.leafProperty is EntityB's annotated property field

2.leafProperty.getOwner() get PersistenceEntity of EntityB

3.leafProperty.getOwner().getPropertyAccessor(parent) try to get audit fileld's accessor of the given bean(which is List<entityB>) from PersistenceEntity of EntityB

4.IllegalArgumentException occurred

 

I've checked github's master branch and seems latest code still have the same behavior

This looks like a duplicate of DATACMNS-1438 which was fixed in 2.1.4. Would mind giving a more recent version a try?

thanks Oliver,I'll try newer version and get back to you with result

Hi Oliver,I found that v2.1.4.RELEASE still not fullfill my question,please correct me if I'm wrong

from v2.1.4.RELEASE, seems only first level entity's audit fields will be audit(EntityA's audit fields),nested property no longer be audit(EntityB in List<EntityB>),is this done on purpose?anyway I can get all entities be audit(entityA.entityB)?

thanks Oliver,I got what I need after careful study of DATACMNS-1438

in general,upcoming v2.2 will take care of nested collection property,for now nested collection will be skipped

Already fixed in 2.1.4, to a more extensive extend in 2.2
