问题 I have a bunch of .xlsx files that are generated every month. I would like to be able to batch move the files to folders which have basically the same name. Example: 123456 Action.xlsx, 123456 RC.xlsx, 123456 PF.xlsx would be the files. The folder would be 123456 Random Center. Is there a way to move those files to that folder using a batch command or something else through the command prompt? Here is the the code I have been trying to use/modify. @echo off pushd "C:\New folder" rem Process

问题 I am new to sprig batch. I have a folder which contain multiple csv file, I have implemented MultiResourceItemReader () to read those file . It is working only if all csv file are pipe line ("|") separated. I want to read both comma (",") separated csv and pipe line separated csv using single reader. Is it possible ? if yes how ? Here is my code @Bean @StepScope public MultiResourceItemReader<Person> multiResourceItemReader(@Value("#{jobParameters[x]}") String x,@Value("#{jobParameters[y]}")

问题 Spring-Batch provides the class FixedLengthTokenizer which makes it easy to read different offsets of a single line into the fileds of an object. Whereby the content of each field is extracted from certain ranges with fixed length: FixedLengthTokenizer tokenizer = new FixedLengthTokenizer(); String[] names = {"A", "B", "C", "D"}; tokenizer.setNames(names); Range[] ranges = {new Range(1, 4), new Range(5, 12), new Range(13, 14), new Range(15, 15)}; tokenizer.setColumns(ranges); I want to do the

问题 I have a list of records to be inserted into DB using my baits. Previously, my code is something like: for(Item item : items){ sqlSession.insert("insert", item); } Using this method works but I find there is dynamical incremental DiskIO at Mysql server, due to number of items. As I have little access to MySql configuration, and hope to resolve this high disk io issue, I find some possible solutions: using ExecutorType.BATCH for sqlSession insert multiple values within a single insert

问题 In Mule, I have quite many records to process, where processing includes some calculations, going back and forth to database etc.. We can process collections of records with these options Batch processing ForEach Splitter-Aggregator So what are the main differences between them? When should we prefer one to others? Mule batch processing option does not seem to have batch job scope variable definition, for example. Or, what if I want to benefit multithreading to fasten the overall task? Or,

问题 I am working on the 3 steps Spring Batch project. Firstly, it downloads needed text files from ftp to local, then process it, and finally delete files in the local directory every 10 minutes. And every 10 minutes there are new files loaded in the FTP. What if there emerge some problem in the FTP and it does not load new files? Then Spring Batch project download same file and process it again. So my question is that how can avoid Spring Batch to process same file twice? Edit: I have used
