Description

There are lots of EL such like SPEL MVEL OGNL, But I need an EL which keep consistency with freemarker template, for example

Expression exp = new Expression("quantity gt 10",freemarkerConfiguration);
Map<String, Object> ctx = new HashMap<>();
ctx.put("quantity", 12);
Object value = exp.eval(ctx); //return Boolean.TRUE
