Json Array reader file with spring batch

Question

I have a file as an input which contain a json Array :

[ {
  ...,
  ...
  },
  {
  ...,
  ...
  },
  {
  ...,
  ...
  }
]

I want to read

Answer 1

This is the record separator policy I wrote starting from your suggestions and from the default implementation. I use an internal plain string representation for the read record, but i found out very simple to parse the JSON with codehaus jettison JSON object.

public class JsonRecordSeparatorPolicy extends SimpleRecordSeparatorPolicy {

/**
 * True if the line can be parsed to a JSON object.
 * 
 * @see RecordSeparatorPolicy#isEndOfRecord(String)
 */
@Override
public boolean isEndOfRecord(String line) {
    return StringUtils.countOccurrencesOf(line, "{") == StringUtils.countOccurrencesOf(line, "}")
            && (line.trim().endsWith("}") || line.trim().endsWith(",") || line.trim().endsWith("]") );
}

@Override
public String postProcess(String record) {
    if(record.startsWith("[")) record = record.substring(1);
    if(record.endsWith("]")) record = record.substring(0, record.length()-1);
    if(record.endsWith(",")) record = record.substring(0, record.length()-1);
    return super.postProcess(record);
}

}
