ReadString FieldSet Method Does Not Read Leading Spaces

I read the records from the file and paste into the database.

I am using a DB2 database.

The entries are as follows:

   abc    pqr  abcd

So, before abc there are several spaces at the beginning of the record.

I am reading the file using the SpringBatch program and inside the set mapper field I am printing the line read from the file:

System.out.println("*" + fieldSet.readString("FULL_RECORD") + "*");

However, I get the result:

*abc    pqr  abcd*

This means that leading spaces are not saved.

Linetokenizer in my configuration file:

<beans:property name="lineTokenizer">
  <beans:bean class="org.springframework.batch.item.file.transform.FixedLengthTokenizer">
    <beans:property name="columns" value="1-241"/>
    <beans:property name="names" value="FULL_RECORD"/>
  </beans:bean>
</beans:property>

I use the mapper class by default and pass the tokenizer above as its property.

org.springframework.batch.item.file.mapping.DefaultLineMapper

How to keep leading spaces before each entry?

take a look at the code

  • Use readString methods to use DefaultFieldset
  • String.trim ()

just change

System.out.println("*" + fieldSet.readString("FULL_RECORD") + "*");

too

System.out.println("*" + fieldSet.readRawString("FULL_RECORD") + "*");

. DefaultFieldSet.readRawString()

String , ( ).
