Thymeleaf 中有 plain context (不支持对url参数的解析)和 web context(支持对url参数的解析)
We'll have to change our code to create a web context, instead of a plain context. Change will be here: 参考:https://github.com/ratpack/ratpack/blob/master/ratpack-thymeleaf/src/main/java/ratpack/thymeleaf/Template.java#L69-69 The IWebContext interface seems coupled to the servlet API, but after quick look at the code I don't think this will be a problem. I think we can just provide null values for things like request/session etc. that we can't provide. If that turns out to be a problem… we can look at providing implementations of those Servlet API type in so far makes sense.
最后附上一份简单的邮件模板文件
