Answer 1

You can utilize the isStrict flag to get read of this issue - use the tokenizer separately and your issue will be solved

I have implemented - fixedLengthTokenizer as below

  @Value("classpath:mainframe.txt")
    private Resource resource;



 @Bean
    public FlatFileItemReader fixLengthItemReader(){
        FlatFileItemReader reader = new FlatFileItemReader();
        reader.setResource(resource);
        reader.setLineMapper(new DefaultLineMapper() {
            {
                setLineTokenizer(fixedLengthTokenizer());
                setFieldSetMapper(new BeanWrapperFieldSetMapper() {
                    {
                        setTargetType(Customer.class);
                    }
                });
            }
        });
        return reader;
    }



@Bean
public FixedLengthTokenizer fixedLengthTokenizer() {
    FixedLengthTokenizer tokenizer = new FixedLengthTokenizer();
    tokenizer.setColumns(new Range[] { new Range(3, 6), new Range(7, 13), new Range(14, 15), new Range(14, 15) });
    tokenizer.setNames(new String[] { "firstValue", "secondValue", "thirdValue", "fourthValue" });
    tokenizer.setStrict(false);
    return tokenizer;
}

Note - do remember to set this flag --> tokenizer.setStrict(false);
