beetl 模板读取的问题

Question

@闲.大赋 你好，想跟你请教个问题：

如何在spring mvc 中让beetl又可以读viewNames里面的模板,又可以读取jar中的模板,而且include不引响?

严重: Servlet.service() for servlet [spring-mvc] in context with path [/web.core] threw exception [Request processing failed; nested exception is java.lang.RuntimeException: java.lang.RuntimeException: java.lang.RuntimeException: java.lang.RuntimeException: ATTRIBUTE_NOT_FOUND] with root cause

Answer 1

用的Tomcat7 我很简单的就在模板上用 ${request.scheme + "://" + request.serverName + ":" + request.serverPort + request.contextPath + "/"} 其它都可以得到,就request.contextPath得不到,我再发我的配置

Answer 2

回复
是有bug，我看看，目前暂时的方案可以使写个方法来完成你这个功能，或者使用ctxPath这个内置变量来代替

Answer 3

回复
新版本修复了这个bug，2.0.11

Answer 4

回复
好的...马上升级,麻烦你了

Answer 5

回复
对了...最好能够极时更新到maven中央库....方便一些....现在只有2.0.8

Answer 6

回复
就是用的2.0.10,我说的也是2.0.10

Answer 7

回复
${request.contextPath} 这个访问报的什么错啊？把详细错误贴出来。另外request是标准的httpservletrequest？

Answer 8

回复
是标准的HttpServletRequest,我也没有去动这个内置的对像,现在都是最原始的配置,但我用2.0.8就没有这个问题,因为比新版本在198行少了个return result;

Answer 9

你好，我开启了beetl的自动检测就报模版加载出错了，能帮我看看吗 错找不到指定模板或者加载错(TEMPLATE_LOAD_ERROR): 位于0行 资源:/modular/html/goods/goods_add.html ClassLoader:sun.misc.Launcher$AppClassLoader@18b4aac2 Path:pages

Answer 10

回复
看提示，你使用了ClassLoader来加载模板，你检查一下pages下是否有你的模板（不是源代码，是目标代码）

Answer 11

这个有点麻烦了，需要重写一个ResourceLoader,建议继承WebFileResourceLoader。在关键方法：

public Resource getResource(String key) 方法中，根据key值来加载模板资源，建议你参考源码自己实现一个
