问题 I'm trying to write the tests for a Spring Batch application, specifically on the interaction from the following reader when it gets records from a database implementing a simple RowMapper : @Component @StepScope public class RecordItemReader extends JdbcCursorItemReader<FooDto> { @Autowired public RecordItemReader(DataSource dataSource) { this.setDataSource(dataSource); this.setSql(AN_SQL_QUERY); this.setRowMapper(new RecordItemMapper()); } } Here is the step definition from the Batch

问题 Our writer is designed to write records to a relational database. If exception occurs on any of the records, Spring Batch performs a rollback and retry write operation on each record in the chunk. This results in SQL Duplicate Key exception to occur since previously processed records in the chunk were successfully written to the database. We have tried making use of noRetry() and noRollback(), specifying explicitly a list of exceptions that should not trigger retry or rollback. According to

问题 I am using Spring Batch to read data from Postgres and write it into the MongoDB . In my case, Employee has 3 different types of email address 1) Home Address 2) Office Address 3) Social Address from Employee Email Table. Since we've almost 10 lacs employees in DB, hence using Custom Partitions to pull the data from Postgres and making the join with employee_email (later employee_phone as well) so that in Processor will have a mapping for Mongo POJO and save into MongoDB. Now the issue is I

问题 I am working on Spring Batch and Partition using the JdbcPagingItemReader , but I am only getting half records. If I am expecting 100 thousand records instead getting only 50 thousand. What's wrong is happening How to use Nested or Inner Query in OraclePagingQueryProvider ?
