Freemarker Tip

request parameter 가져오기

${RequestParameters.aaa} or ${RequestParameters.['aaa']}

 

request attributes 가져오기

${Request.aaa} or ${Request.['aaa']}

Default value operator : !

그 값이 없을때 default value를 명시할수 있다.

예를 들어 mouse 에 값이 없을때

	${mouse!"No mouse."} <#assign mouse="Jerry"> ${mouse!"No mouse."}

The output will be:

	No mouse. Jerry

또다른 예

	(${mouse!}) <#assign mouse = "Jerry"> (${mouse!})

The output will be:

	() (Jerry)

Escape Example:

	<#escape x as x?html> First name: ${firstName} Last name: ${lastName} Maiden name: ${maidenName} </#escape>

is actually equivalent to:

	First name: ${firstName?html} Last name: ${lastName?html} Maiden name: ${maidenName?html}

null값 체킹
<#if param1??>

// param1은 null아 아니다.

</#if>

List 관련 작업
<#list list as item>
            <#if (item_index > 0)> // 2번째 item 부터... </#if>
            <#if item_has_next> // 다음 item 이 있다면... </#if>
</#list>
