本文的重点是如何在JSP中使用FreeMarker标签，有人可能会问：为什么不直接在FreeMarker模版文件中使用JSP标签呢？这是个很好的问题，因为大部分人在使用FreeMarker多半是会用FreeMarker文件格式（.ftl）. 但是，试想想如果我们只是想在现有的系统中集成FreeMarker，如果我们要把所有JSP文件改成FTL文件，那么是需要很多时间的，在这种情况下，最好的办法就是在JSP中直接使用FreeMarker标签（一般情况下，我们很有可能在JSP中使用FreeMarker的宏）。那么如何在JSP中使用FreeMarker呢，很简单，我们必须使用JSP的<%@ taglib ... />命令，把FreeMarker的标签库文件（fmtag.tld）导入，本文把 fmtag.tld 放到WEB-INF目录下，下面是 fmtag.tld 的源码： hello.jsp
view plaincopy to clipboardprint? <%@ taglib uri="/WEB-INF/fmtag.tld" prefix="fm" %> <html> <head> <title>Login</title> </head> <body> <h1>Hello World.</h1> <fm:template> <#assign y="Hello World"> ${y} <#assign seq = ["winter", "spring", "summer", "autumn"]> <#list seq as x> ${x_index + 1}. ${x}<#if x_has_next>,</#if> </#list> </fm:template> </body> </html> <%@ taglib uri="/WEB-INF/fmtag.tld" prefix="fm" %> <html> <head> <title>Login</title> </head> <body> <h1>Hello World.</h1> <fm:template> <#assign y="Hello World"> ${y} <#assign seq = ["winter", "spring", "summer", "autumn"]> <#list seq as x> ${x_index + 1}. ${x}<#if x_has_next>,</#if> </#list> </fm:template> </body> </html> 大家注意了FreeMarker的部分必须放在标签<fm:template>与</fm:template>之间，否则JSP不会解析FreeMarker的内容，会把源码输出在页面之中 |
