FreeMarker is a Java-based template engine that allows developers to generate dynamic content by combining templates with data models. FTL (FreeMarker Template Language) is the syntax used by FreeMarker to define templates. FTL files typically contain a mix of HTML, CSS, and FreeMarker expressions. FreeMarker expressions are enclosed in ${} and can contain variables, operators, and control structures such as loops and conditionals. Example FTL code: ``` <!DOCTYPE html> <html> <head> <title>${title}</title> </head> <body> <h1>${heading}</h1> <ul> <#list items as item> <li>${item}</li> </#list> </ul> </body> </html> ``` In this example, ${title}, ${heading}, and ${item} are FreeMarker expressions that will be replaced with values from the data model at runtime. The #list directive is a control structure that iterates over a collection of items. FreeMarker is widely used in Java web development frameworks such as Spring and Struts, as well as in standalone applications. It provides a powerful and flexible way to generate dynamic content that can be customized based on user input or other factors.
