Release Notes

0.9.0 (in progress)

  • BREAKING: removed backwards compatibility to load stores without metadata (introduced in version 0.5.0)
  • BREAKING: moved de.chrgroth.jsonstore.store.JsonStoreMetadata to de.chrgroth.jsonstore.JsonStoreMetadata class so please correct classname in existing json files manually once
  • BREAKING: introduced some API changed breaking causing compile errors
  • convenience method to load all stores in case auto save mode is disabled
  • added optional payload class qualifier to be able to handle multiple stores using the same payload class
  • created interface de.chrgroth.jsonstore.JsonService regarding all JSON operations and a default implementation for currently used flexjson library
  • created interface de.chrgroth.jsonstore.StorageService regarding all storage operations and a default implementation for currently used file based storage
  • ...

0.8.1

  • avoid direct save after load without changes
  • enhanced lifecycle logging

0.8.0

  • fixed bug if a custom handler for java.util.Date or java.time.LocalDateTime is registered
  • added methods to add handlers for specific store only
  • added deep serialization mode to json stores, see flexjson documentation for detailed information
  • fixed NPE during deserialization for transient stores

0.7.1

  • avoid StringInterningHandler to be set on flexjson serializer, this will kill all stings in resulting json and produce invalid json syntax

0.7.0

  • fixed handling of stores created date
  • added simple on demand statistics computation to store instances
  • added option to intern all Strings on deserialization to FlexjsonHelperBuilder

0.6.1

  • version migration did not save new version number in metadata correctly
  • avoid duplicate loading of json data from file during ensure json store

0.6.0

  • fixed payload migration without metadats
  • payload without metadata is considered to have version number 0, allowing direct migration
  • removed deprecated ensure methods on JsonStores
  • removed JsonStores#load() due to mandatory version per store. Ensure methods will trigger load now if auto save is enabled.
  • toJson() without explicit pretty print mode takes pretty print value from store, was false before.
  • JsonStoreException will be thrown if data loading fails, because this may lead to overriding existing data with next (auto-)save operation. Errors during save and drop are still just logged and silently ignored otherwise.

0.5.0

  • introduced metadata to JSON store wrapping stored payload, existing persistent data will be converted automatically during first load
  • added payload version migration before deserialization to java instances based on metadata
  • added options to provide flexjson transformers and object factories for JSON serialization and deserialization using AbstractFlexjsonTypeHandler
  • enhanced testcases

0.4.0

  • made date time pattern configurable
  • refactored package structure from com.github.christiangroth to de.chrgroth
  • changed maven group id from com.github.christiangroth to de.chrgroth.json-store
  • including java debug information

0.3.0

  • using copy of data internally when creating streams to avoid ConcurrentModificationException if underlying set is changed during stream handling
  • added support for Java 8 Time API. Beneath java.util.date you may also use java.time.LocalDateTime in JSON entities
  • refactored package structure, com.github.christiangroth.jsonstore.JsonStore moved to com.github.christiangroth.jsonstore.store subpackage
  • added com.github.christiangroth.jsonstore.store.JsonSingletonStore to provide storage for single object only
  • fixed NullPointerException during initialization of transient JsonStores
  • switched to builder pattern to create JsonStores instance, use JsonStores.builder() to get started
  • made charset configurable using stores builder

0.2.0

  • changed package names to match Maven group id
  • using copied data set to produce JSON data to avoid ConcurrentModificationException (happens while saving data to file and changing store data simultaneously)
  • added slf4j logging api
  • using UTF-8 for file operations

0.1.0

  • initial release
