boot结合freemaker，template文件都在jar包中，如何正确配置资源路径？

在gradle中仅此一个与freemaker有关的依赖配置

compile group: 'org.nutz', name: 'nutzboot-starter-freemarker', version: '2.1.5'

在application.properties中有关配置

freemarker.suffix=.ftl

模板文件资源位置：src-main-resources-template
在ide中跑是正常的，可以正确显示模板内容在client端，但是打包发布到生产环境会抛出以下异常：

看了以下fm的文档，有关资源读取的方式如下

Built-in template loaders
void setDirectoryForTemplateLoading(File dir):
void setClassForTemplateLoading(Class cl, String basePackagePath)
void setServletContextForTemplateLoading(Object servletContext, String path)

又看了下starter初始化源码

protected void initFreeMarkerConfigurer() throws IOException, TemplateException {
		String path = freemarkerDirectiveFactory.getFreemarker();
		File file = Files.findFile(path);
		if (!Lang.isEmpty(file)) {
			Properties p = new Properties();
			p.load(Streams.fileIn(file));
			configuration.setSettings(p);
		}
		File f = Files.findFile(prefix);
		configuration.setDirectoryForTemplateLoading(f);
	}

貌似只提供了一种读取的方式，请问该如何解决？谢谢

路过，围观一波。

看上去是bug，来报个issue

额感觉等更新版本有点着急有什么临时补救方法吗？

可以把template拷贝一下，跟jar放在同一个文件夹试试

七星爆珠(wx_23p8gq8rj75i01c098r7) 5楼•2404天前

嗯试过了也不行的

wendal

6楼•2404天前

debug一下，看看在idea环境下f的指是什么

七星爆珠(wx_23p8gq8rj75i01c098r7) 7楼•2404天前

是template文件系统的绝对路径路径也是正确的

七星爆珠(wx_23p8gq8rj75i01c098r7) 8楼•2404天前

protected void initFreeMarkerConfigurer() throws IOException, TemplateException {
		String path = freemarkerDirectiveFactory.getFreemarker();
		File file = Files.findFile(path);
		if (!Lang.isEmpty(file)) {
			Properties p = new Properties();
			p.load(Streams.fileIn(file));
			configuration.setSettings(p);
		}
		File f = Files.findFile(prefix);---------------------------------感觉这里在生产环境下应该是空，资源在jar文件中
		configuration.setDirectoryForTemplateLoading(f);

那一行里面，prefix的值是多少呢？

wendal

10楼•2404天前

如果启动时的文件夹也是在jar所在的文件夹，然后template文件夹也在jar所在的文件夹，应该是能找到的

七星爆珠(wx_23p8gq8rj75i01c098r7) 11楼•2404天前

prefix = /D:/work/ProjectA/02_modulet/out/production/resources/template

有个终极版本，把FreeMarkerConfigurer源码拷贝过，相同package下，优先级比jar高，直接改之

七星爆珠(wx_23p8gq8rj75i01c098r7) 13楼•2404天前

可以可以这个终极大招果然好使！！！只修改了一行代码，ide和生产环境下就都跑通了

configuration.setClassForTemplateLoading(getClass(),"template");

嗯嗯, 记得报个issue
