Sorry, the example was incomplete. It should be like this: @Test public void testReplaceEscapingDollarSign() { values.put("amount", "20.00");
final StrSubstitutor sub = new StrSubstitutor(values); sub.setEscapeChar('<'); String replaceTemplate = "The <${animal} jumps over the ${target}."; String expectedResult = "The ${animal} jumps over the lazy dog."; String replacedResult = sub.replace(replaceTemplate); assertEquals(expectedResult, replacedResult); replaceTemplate = "The ${animal} paid <$${amount} to jump over the ${target}."; expectedResult = "The quick brown fox paid $20.00 to jump over the lazy dog."; replacedResult = sub.replace(replaceTemplate); assertEquals(expectedResult, replacedResult); } The second assertion failed. So, it seems working in case of "<${animal}", but not working in case of "<$${amount}". testReplaceEscapingDollarSign(org.apache.commons.lang3.text.StrSubstitutorTest) Time elapsed: 0.009 sec <<< FAILURE! org.junit.ComparisonFailure: expected:<...uick brown fox paid []$20.00 to jump over ...> but was:<...uick brown fox paid [<]$20.00 to jump over ...> Regards, Woonsan On Thu, Jul 23, 2015 at 10:28 AM, Woonsan Ko <woon...@apache.org> wrote: > Hi Anthony, > > Putting '$20.00' into the map is not an option in my use case, so I > tried to use a different escape character.
