I'm using spring-data-mongodb-1.2.0.RELEASE. I have two classes A and B where B has a reference to A and it is annotated with @DBRef.
Class A:
Class B:
After creating and associating A and B instances:
I'm able to execute the next query:
But(!!!), when I'm executing findAndRemove:
I'm getting this:
java.lang.RuntimeException: json can't serialize type : class org.jasig.cas.ticket.registry.entities.A at com.mongodb.util.ClassMapBasedObjectSerializer.ser ialize(ClassMapBasedObjectSerializer.java:77) at com.mongodb.util.JSONSerializers$MapSerializer.ser ialize(JSONSerializers.java:307) at com.mongodb.util.ClassMapBasedObjectSerializer.ser ialize(ClassMapBasedObjectSerializer.java:79) at com.mongodb.util.JSON.serialize(JSON.java:56) at com.mongodb.util.JSON.serialize(JSON.java:41) at com.mongodb.BasicDBObject.toString(BasicDBObject.j ava:83) at java.lang.String.valueOf(String.java:2826) at java.lang.StringBuilder.append(StringBuilder.java: 115) at org.springframework.data.mongodb.core.MongoTemplat e.doFindAndRemove(MongoTemplate.java:1392) at org.springframework.data.mongodb.core.MongoTemplat e.findAndRemove(MongoTemplate.java:572) at org.springframework.data.mongodb.core.MongoTemplat e.findAndRemove(MongoTemplate.java:568)
Does someone have an idea why?
Class A:
Code:
@Document(collection = "a")
