问题 I am looking to integrate the Spring Batch with RabbitMQ. I've developed code like below but no data is passing over the channel. What's wrong in the code ? CustomerMessageChannel.java public interface CustomerMessageChannel { @Output("customerMessageChannel") MessageChannel customerMessageChannel(); } Customer.java @AllArgsConstructor @NoArgsConstructor @Builder @Data @JsonIgnoreProperties(ignoreUnknown = true) public class Customer implements Serializable { private static final long

问题 I have a simple Spring Boot application with an enpoint that invokes a Spring Batch Job asynchronously through the SimpleAsyncTaskExecutor configured in the JobLauncher bean. The Spring Batch Job starts asynchronously and works fine, but nothing is saved to the database. If I remove the SimpleAsyncTaskExecutor the data is saved. This is my BatchConfigurer. Heere I configure the JobLauncher with a SimpleAsyncTaskExecutor . If I remove the line simpleJobLauncher.setTaskExecutor(new

问题 I need to denormalize data stored into a relational database. There are too much tables linked between each others, and it's not possible to build a single query to get every data. Here a simplified situation: +-------------+ +-------------+ | | 1 N | | | Unitat +-----------> Authors | | | | | +-------------+ +-------------+ Up to now I've build an step that is getting all Unitat rows: @Bean public ItemReader<Unitat> reader() { String sql = "select * from unitat"; JdbcCursorItemReader<Unitat>

问题 I have a record split into multiple lines in a file. Only way to identify the end of the record is when new record starts with ABC. Below is the sample. File size could be 5-10 GB and I am looking for a efficient java logic ONLY to split the files(no need of reading every line), but splitting logic should a check to start a new file with new record, which should start with "ABC" in this case. Added few more details, I am just looking for splitting the file and while splitting the last record
