Class JsonRecordSeparatorPolicy

java.lang.Object
  org.springframework.batch.item.file.separator.SimpleRecordSeparatorPolicy
      org.springframework.batch.item.file.separator.JsonRecordSeparatorPolicy

All Implemented Interfaces:

RecordSeparatorPolicy

public class JsonRecordSeparatorPolicy
extends SimpleRecordSeparatorPolicy

JSON-based record separator. Waits for a valid JSON object before returning a complete line. A valid object has balanced braces ({}), possibly nested, and ends with a closing brace. This separator can be used to split a stream into JSON objects, even if those objects are spread over multiple lines, e.g.

 {"foo": "bar",
  "value": { "spam": 2 }}
  {"foo": "rab",
  "value": { "spam": 3, "foo": "bar" }}
