Escaping quotes in velocity template

问题:

I have a java method, that takes a few strings. This method needs to be called from a Velocity Template. However, the strings are too complex, with lots of single quotes, double quotes and commas as well. As a result merge is failing. Is there a way to escape quotes in Velocity?

回答1:

It depends on which version of Velocity you're using. Velocity 1.7 has clear rules for escaping quotes: just double the same type of quotes used to wrap the string:

$object.callMethod('Let''s have fun with "quotes"',
  "Let's have fun with ""quotes""")

Prior to that, there were some fuzzy rules with backslash escapes that didn't always work as expected.

See the Velocity Escape Tool:
