com.jfinal.template.source

Class ClassPathSource

java.lang.Object

com.jfinal.template.source.ClassPathSource

All Implemented Interfaces:

ISource

public class ClassPathSource
extends Object
implements ISource

ClassPathSource 用于从 class path 以及 jar 包之中加载模板内容

 注意：
 1：如果被加载的文件是 class path 中的普通文件，则该文件支持热加载
 
 2：如果被加载的文件处于 jar 包之中，则该文件不支持热加载，jar 包之中的文件在运行时通常不会被修改
    在极少数情况下如果需要对 jar 包之中的模板文件进行热加载，可以通过继承 ClassPathSource
    的方式进行扩展
 
 3：JFinal Template Engine 开启热加载需要配置 engine.setDevMode(true)
