问题 My data is like this UserId,UserData 1,data11 1,data12 2,data21 3,data31 The question is how I can make the spring batch itemreader read multiple lines and map to object like Map < userid, List < userdata > > Thanks. 回答1: Steps to follow: create a custom Item Writer class by implementing ItemWriter where we have implemented a logic to store User object in Map<String,List<String>> because a single user can have multiple associated data package com.spring.batch.domain; import java.util

问题 I have implemented a spring-batch job to process a 10gb file with one item per file and it works great! But the client just changed it to make it a 10gb file with one single line with all items on it separated by size.
