java.lang.IllegalArgumentException: can't serialize class Type

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • Enums cannot be serialized without transforming them. I propose, that all java enums are serialized (and deserialized) using the name() method (or valueOf() method). Example (using QueryDSL): @Entity public enum Type { TYPE1, TYPE2 } public class MyObject { protected Type type; public Type getType() { } public void setType(Type type) { this.type = type; } } Usage: QMyObject.myObject.type.eq(Type.TYPE1); // ends in: java.lang.IllegalArgumentException: can't serialize class Type at org.bson.BSONEncoder._putObjectField(BSONEncoder.java:213) at org.bson.BSONEncoder.putObject(BSONEncoder.java:123) at org.bson.BSONEncoder._putObjectField(BSONEncoder.java:173) at org.bson.BSONEncoder.putObject(BSONEncoder.java:123) at org.bson.BSONEncoder.putObject(BSONEncoder.java:69) at com.mongodb.OutMessage.putObject(OutMessage.java:189) at com.mongodb.OutMessage._appendQuery(OutMessage.java:62) at com.mongodb.OutMessage.query(OutMessage.java:39) at com.mongodb.DBApiLayer$MyCollection.__find(DBApiLayer.java:293) at com.mongodb.DB.command(DB.java:152) at com.mongodb.DBCollection.getCount(DBCollection.java:760) at com.mongodb.DBCollection.getCount(DBCollection.java:731) at com.mongodb.DBCollection.count(DBCollection.java:697) at com.mysema.query.mongodb.MongodbQuery.count(MongodbQuery.java:184) at org.springframework.data.document.mongodb.repository.QueryDslMongoRepository.count(QueryDslMongoRepository.java:151) at sun.reflect.GeneratedMethodAccessor9.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.springframework.data.repository.support.RepositoryFactorySupport$QueryExecuterMethodInterceptor.executeMethodOn(RepositoryFactorySupport.java:356) at org.springframework.data.repository.support.RepositoryFactorySupport$QueryExecuterMethodInterceptor.invoke(RepositoryFactorySupport.java:337) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:172) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:202) at $Proxy18.count(Unknown Source)
