freeMarker 数字格式化问题

感谢:http://hi.baidu.com/imaogo/blog/item/46daa794006cf81dd31b70f3.html

问题：

freemarker在模板中的数据比如1024，超过1000，就会变成1，024

怎么样让它原样输出

回答：

可在web.xml里面配置

<servlet>

<servlet-name>freemarker</servlet-name>

<servlet-class>freemarker.ext.servlet.FreemarkerServlet</servlet-class>

<!-- FreemarkerServlet settings: -->

<init-param>

<param-name>TemplatePath</param-name>

<param-value>/WEB-INF/template</param-value>

</init-param>

<init-param>

<param-name>NoCache</param-name>

<param-value>true</param-value>

</init-param>

<init-param>

<param-name>ContentType</param-name>

<param-value>text/html</param-value>

</init-param>

<!-- FreeMarker settings: -->

<init-param>

<param-name>template_update_delay</param-name>

<param-value>0</param-value> <!-- 0 is for development only! Use higher value otherwise. -->

</init-param>

<init-param>

<param-name>default_encoding</param-name>

<param-value>UTF-8</param-value>

</init-param>

<init-param>

<param-name>locale</param-name>

<param-value>en_US</param-value>

</init-param>

<init-param>

<param-name>number_format</param-name>

<param-value>0.##########</param-value>

</init-param>

<init-param>

<param-name>date_format</param-name>

<param-value>yyyy-MM-dd</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>freemarker</servlet-name>

<url-pattern>*.ftl</url-pattern>

</servlet-mapping>

另外补充一点，如果只是用ftl展示数据的话，以上配置是可以的。但是如果用ftl作模版生成Html时，可能还会出现类似问题，这好像是freemarker的一个bug，所以还需要在代码里面显式的设置

Configuration cfg = new Configuration()

....

cfg.setNumberFormat("0.##########");
