我正在尝试从START-OF-DATA行到END-OF-DATA行读取未格式化的附件文本文件，并忽略文件中的所有其他行。sampleText file

我像下面那样创建了读取器，由于我的文件是非结构化的，并且无法在执行器数据之前包含多余的行，因此无法正常工作

public CustomflatFileItemReader<MyBean> reader() {
    CustomflatFileItemReader<MyBean> reader = new CustomflatFileItemReader<MyBean>();

    reader.setLineMapper(new DefaultLineMapper<InterestRate>() {{
        setLineTokenizer(new DelimitedLineTokenizer("|") {{
            setNames(new String[] { "name","refKey1","refKey2","refKey4","refKey5","refKey6","refKey7"});
        }});
        setfieldSetMapper(new BeanWrapperFieldSetMapper() {{
            setTargetType(MyBean.class);
        }});
    }});
    return reader;
