Source Link

Document

Read the String value from column with given 'name' including trailing whitespace (don't trim).

Usage

From source file:de.langmi.spring.batch.examples.readers.file.tokenizers.DelimitedLineTokenizerTests.java

/**
 * Standard tokenizer test with white space values.
 * Shows the differences for readString and readRawString, first one
 * trims whitespace./*  ww  w  .  j av a  2  s.  c o  m*/
 *
 * @throws Exception
 * @see http://forum.springsource.org/showthread.php?114765-Issue-FlatFileItemReader-automatically-Trimming-the-leading-and-trailing-spaces
 */
@Test
public void testWithSpaces() throws Exception {
    // set names only, standard configuration
    tokenizer.setNames(new String[] { "id", "value1", "value2" });
    // fire
    FieldSet fieldSet = tokenizer.tokenize("1,   foo   ,   bar");

    // assertions
    assertNotNull(fieldSet);
    assertTrue("field count", fieldSet.getFieldCount() == 3);
    assertEquals("1", fieldSet.readString("id"));
    // readString trims
    assertEquals("foo", fieldSet.readString("value1"));
    assertEquals("bar", fieldSet.readString("value2"));
    // readRawString does not trim
    assertEquals("   foo   ", fieldSet.readRawString("value1"));
    assertEquals("   bar", fieldSet.readRawString("value2"));

    // assertions with properties
    Properties props = fieldSet.getProperties();
    // the used fieldSet impl. trims whitespace in its getProperties method
    // see http://forum.springsource.org/showthread.php?114765-Issue-FlatFileItemReader-automatically-Trimming-the-leading-and-trailing-spaces
    // for follow up problems e.g. with BeanWrapperFieldSetMapper
    assertEquals("foo", props.getProperty("value1"));
    assertEquals("bar", props.getProperty("value2"));
