freemarker template engine ------try catch if else loop

clock March 18, 2015 12:58 by author Administrator


i think one of best solution for generate code is using template engine like freemarker.
for using try catch or if else and some other expression in it using like this

attempt block

recover block

<#if x == 1> x is 1
<#elseif x == 2> x is 2
<#elseif x == 3> x is 3

<#list fields as field>

this template generate fileds for hibernate hbm.xml

<#list fields as field>
<#if "${field.type.superclass}"=="class org.model.BaseEntity">
<many-to-one name="${}" column="${}" entity-name="${}" not-null="true" />
<property column="${}" name="${}" type="${field.type.simpleName}" not-null="false" />
<property column="${}" name="${}" type="${field.type.simpleName}" not-null="false" />
