Apache FreeMarker is a template engine: a Java library to generate text output (HTML web pages, e-mails, configuration files, source code, etc.) based on templates and changing data. Templates are written in the FreeMarker Template Language (FTL), which is a simple, specialized language (not a full-blown programming language like PHP). You meant to prepare the data to display in a real programming language, like issue database queries and do business calculations, and then the template displays that already prepared data. In the template you are focusing on how to present the data, and outside the template you are focusing on what data to present.

- 原理：就我个人的理解模板的诞生是为了将显示与数据分离，其本质是将模板文件和数据通过模板引擎生成最终的HTML代码（如图）
