Collection required when maxOccurs is greater than 1 and class is set

[Renato Souza]

Hello. I'm using the 2.1.0 version of beanio and I need to map one file whose structure is the following:

HEADER

 

 n RECORDS

 

 TRAILER

I've annotated everything and I'm building the objects using StreamBuilder. Here is the code:

        GroupBuilder groupBuilder = new GroupBuilder("file")
            .type(PaymentSlipFile.class)
            .addRecord(PaymentSlipHeader.class)
            .addRecord(PaymentSlipRecord.class)
            .addRecord(PaymentSlipTrailer.class);
       
        StreamBuilder streamBuilder = new StreamBuilder("paymentslip")
            .format("fixedlength")
            .parser(new FixedLengthParserBuilder().recordTerminator("\r\n"))
            .addGroup(groupBuilder);

        factory.define(streamBuilder);
        BeanReader in = factory.createReader("paymentslip", new FileReader(file));
        PaymentSlipFile psFile = (PaymentSlipFile) in.read();
        in.close();

And here are my annotated classes:

@Group(order = 1, name = "file")
public class PaymentSlipFile {

    private PaymentSlipHeader header;
    private List<PaymentSlipRecord> records = new ArrayList<PaymentSlipRecord>();
    private PaymentSlipTrailer trailer;

}

@Record(name="header", order = 1, minOccurs = 1, maxOccurs = 1)
public class PaymentSlipHeader {

    @Field(at = 0, length = 1, rid = true, literal = "0")
    private Integer headerCode;

}

@Record(name = "records", order = 2, minOccurs = 1, maxOccurs = -1, collection = PaymentSlipRecord.class)
public class PaymentSlipRecord {

    @Field(at = 0, length = 1, rid = true, literal = "1")
    private Integer recordType;

}

@Record(name = "trailer", order = 3, minOccurs = 1, maxOccurs = 1)
public class PaymentSlipTrailer {

    @Field(at = 0, length = 1, rid = true, literal = "9")
    private Integer recordType;

}

 

As always I'm having trouble mapping the 'n' records thing.
Everything I try gives the same error:

org.beanio.BeanIOConfigurationException: Invalid record 'records', in group 'file', in stream 'paymentslip': Collection required when maxOccurs is greater than 1 and class is set
Caused by: org.beanio.BeanIOConfigurationException: Collection required when maxOccurs is greater than 1 and class is set

If I change the List<PaymentSlipRecord> to a single PaymentSlipRecord object and set its maxOccurs to 1, then it works.
But I really need the "n records" working.
Any tips?

ps.: of course i cut some code to simplify

Hello,

I think you just need to move the @Record annotations to the fields in the PaymentSlipFile class, and then your GroupBuilder becomes:

GroupBuilder groupBuilder = new GroupBuilder("file")

            .type(PaymentSlipFile.class);

i.e. no need to explicitly add the records.

Thanks,

Kevin

If I do so, I get the following error:

Caused by: org.beanio.BeanIOConfigurationException: At least one record or group is required.

And my group code is:

@Group(order = 1, name = "file", xmlType = XmlType.NONE)
public class PaymentSlipFile {

    @Record(name="header", order = 1, minOccurs = 1, maxOccurs = 1)

    private PaymentSlipHeader header;
    @Record(name = "records", order = 2, minOccurs = 1, maxOccurs = -1, collection = List.class)
    @Fields({
        @Field(name = "recordType", at = 0, length = 1, rid = true, literal="1")
    })

    private List<PaymentSlipRecord> records = new ArrayList<PaymentSlipRecord>();

    @Record(name = "trailer", order = 3, minOccurs = 1, maxOccurs = 1)

    private PaymentSlipTrailer trailer;

}

I am getting the exact same issue. Did you figure out how to correct this one? There is very little documentation and examples on how to use beanio with annotations.

[Renato Souza]

Dude, I fixed this issue, but I don't remember how anymore.. it was a long time ago.

But I looked in my old codes here and found this particular one.

My @Group file has exactly the same code as my last post.

Maybe the problem was on the repeatable @Record.. so here is it's mapping:

@Record(name = "records", order = 2, minOccurs = 1, maxOccurs = -1, collection = List.class)
@Fields({

 @Field(name = "id", at=0, length = 1, rid = true, literal="1")
})

And here is the mapping of the field representing the ID of this @Record:

@Field(at = 0, length = 1, rid = true, literal = "1") 

private Integer id; 

I believe the problem was with this rid = true (it was not declared before).

Good luck.

I have put the rid = true but it still gives me the same issue. Did you also use a mapping file? I am not using a mapping file and hoping annotations should be sufficient.

[Renato Souza]

no mapping xml.. annotations only

[Bob Dixon]

ritz, did you ever resolve your issue?

I'm receiving a similar error.  I seem to be having trouble with Grouping the different records.

org.beanio.BeanIOConfigurationException: Invalid group 'file', in stream 'cbinput': At least one record or group is required.

 

My annotated definitions are very in the same order and format as Renato Souza.  

[Renato Souza]

Does your entities have any property that identifies the entity uniquely? Something like an @Id of JPA?

If so, try to set rid = true on its @Field.

My solution was something like this.

Hope it helps.

Thank you for responding.

Yes, I included the rid=true on my annotated fields for each record.  

I'm sure there is some simple configuration that I have incorrect.  I'm a bit new to this sort of programming so I could easily be missing something.

I've posted more detail of my issue on the following topic.  "Having trouble defining the grouping for multiple annotated record types using StreamFactory."  https://groups.google.com/forum/?fromgroups#!topic/beanio/pMIsmiPdF5E
