Миграция из весенней партии 3 в 4

/ 28 марта 2019

Я пытаюсь перейти с Spring Batch 3.0.6 на 4.1.1.

Я застрял при обработке данных контекста выполнения Spring Batch, как объяснено здесь .

Мне бы хотелось обновить таблицы batch_step_execution_context и batch_step_execution_context для каждой записи следующим образом:

  • десериализация контекстных данных с использованием устаревших XStreamExecutionContextStringSerializer
  • сериализация Java-объекта, полученного с помощью Джексона ObjectMapper
  • обновить таблицу, используя эту новую строку

Это сработало для некоторых записей, и я мог запустить Spring Batch 4. Но для некоторых заданий новая строка не десериализуема как ExecutionContext.

Вот пример такой строки: 

{
   "setMoisAffaires":[
      {
         "premierJourDuMois":{
            "date":1257030000000,
            "stringFromDatePatternAmericain":"2009-11-01",
            "hour":0,
            "year":2009,
            "dayOfMonth":1,
            "dayOfWeek":7,
            "dateString":"20091101",
            "monthOfYear":11,
            "minuteOfHour":0,
            "secondOfMinute":0
         },
         "date":1257030000000,
         "stringFromDatePatternAmericain":"2009-11-01",
         "hour":0,
         "year":2009,
         "dayOfMonth":1,
         "dayOfWeek":7,
         "dateString":"200911",
         "monthOfYear":11,
         "minuteOfHour":0,
         "secondOfMinute":0
      },
      //a lot of records like the previous...
   ],
   "batch.taskletType":"com.sun.proxy.$Proxy57",
   "batch.stepType":"org.springframework.batch.core.step.tasklet.TaskletStep"
}

Вот след, когда я пытаюсь сделать: ExecutionContext a = objectMapper.readValue(objectMapper.writeValueAsString(javaObject),ExecutionContext.class);

Exception in thread "main" com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "setMoisAffaires" (class org.springframework.batch.item.ExecutionContext), not marked as ignorable (one known property: "dirty"])

То, что было сериализовано с XStream, не обязательно десериализуемо с Джексоном. Поэтому я не уверен, как вы можете решить эту проблему. См. Примечание об изменениях здесь .

РЕДАКТИРОВАТЬ: После добавления минимального полного проверяемого примера

XStreamExecutionContextStringSerializer#deserialize возвращает Map<String, Object> пар ключ / значение старого контекста выполнения. Я бы использовал эту карту непосредственно в качестве входных данных для сериализатора Джексона, вместо того, чтобы маршалировать его в строку и затем создавать обратно из строки. Вот как я обновил тест:
