By doing so, it allows developers to not spend an inordinate amount of time solving all of the technical aspects to support the solution. Later on it was determined that an additional business unit needed the same data, however they needed the data output in the format of a pipe-delimited text file with only three of the fields.

The first thing we need to do is to create the shell of our ItemStreamWriter. Here is what the shell looks like: I also found that there were some issues with the previous example related to the data stream coming from Nasdaq.

The format of one of the fields had changed and the example was no longer working, so that had to be fixed before we could continue on. Since the data format had changed and these blog articles use mostly static examples, I have created an input file of stock data named companylist. Modifed the stock data reader to use this data file instead of the live Nasdaq feed.

This is required since the MultiFormatItemWriter will be scoped at the step level. Commented out the for loop inside that write method that was writing each record times to the excel file. This was used for the large excel file demonstration, so that would need to be reverted for that example to work again.

The second output should be in a pipe delimited text file and only contain the symbol, name and last sale fields. To use this is a very simple configuration change and it looks like this: The BeanWrapperFieldExtractor takes the list of StockData records that is sent to the ItemStreamWriter and extracts the fields specified by the comma delimited list of field names that are found in the StockData bean.

Finally, specifying the resource for output which in this case is the file extract-example. Now all we need to do is wire the two delegate writers into our MultiFormatItemWriter.

Spring Batch Tutorial: Writing Information to a File

It does almost the exact same thing as I have done here, only it takes a list of ItemWriters and loops through them in each method that is implemented.

So my point with this article today is to express how easy most common tasks and business solutions can be solved with several of the already implemented components that are provided with Spring Batch.

In Spring batch, the wired Processor will be fired before writing to any resources, so, this is the best place to handle any conversion, filtering and business logic. In this example, the Report object will be ignored (not write to csv file) if its’ age is equal to Now that we’ve addressed the StockDataExcelWriter, we need to address the additional format output that the business alphabetnyc.com second output should be in a pipe delimited text file and only contain the symbol, name and last sale fields. Mar 28,  · Thank you for your help. I guess extending FlatFileItemWriter is not a solution to dynamically generating a unique filename because the setter will be called only once when the bean is instantiated. So, I will have to look for some other solution.

This and the other examples can be found over at GitHub at the following location:Mar 28,  · Thank you for your help. I guess extending FlatFileItemWriter is not a solution to dynamically generating a unique filename because the setter will be called only once when the bean is instantiated.
