            else
                return false;
        }
    });
    // String str = "${json.name}"; jaskson 支持get方法，因此不用虚拟属性也能访问
    String str = "${json.~name}";
    Template template = gt.getTemplate(str, new StringTemplateResourceLoader());
    template.binding("json", node);
    String ret = template.render();
    AssertJUnit.assertEquals("\"lijz\"", ret);
