What is freemarker template

A template engine combines static data with dynamic data to produce content. A template is an intermediate representation of the content; it specifies how the output will be generated. FreeMarker is not restricted to templates for HTML pages; it can be used to generate e-mails, configuration files, source code etc.

The first two applications are console applications. They use the following Maven build file:. FreeMarker will replace an interpolation in the output with the actual value of the expression inside the curly brackets.

The example prints a simple text to the console. The final text was processed by a template engine. Configuration is used to set the FreeMarker settings; it takes the version of the FreeMarker library as a parameter. The setClassForTemplateLoading sets the class whose method will be used to load templates. The data model is created. The data from the model will be dynamically placed into the FreeMarker template file.

The process method executes the template, using the provided data model and writing the generated output to the supplied writer. The test. This example is a Java console program, which uses FreeMarker to dynamically create a text output containing a list of cars. Here we create an ArrayList of Car objects and put it into the data model. The template file contains a list directive which prints the attributes of the car objects; the attributes are accessed with the dot character.

FreeMarker directives are special tags that perform an action. There are two kinds of directives: built-in and custom. The variable is created in the template. If there is an equally named variable in the data model, the template variable hides it. The example creates a new value variable and uses conditional directives to test the value.

In the example, we assing a new sequence of colour names to the colours variable. In the following example, we use FreeMarker in a standard Java web application.

Off course, all three expressions can be arbitrary complex. The argument expressions can have any type, even different types. The first subvariable of the sequence. Template processing will die with error if the sequence is empty. Join Concatenates the items of a sequence to a single string, with the given separator. The number of sub variables in sequence as a numerical value. The highest possible index in sequence s is s? Returns the sequence sorted in ascending order.

For descending order use this and then the reverse built in. If the sub variables are strings, it uses locale language specific lexical sorting which is usually not case sensitive. A sequence that contains all the lookup keys in the hash. Note that not all hashes support this ask the programmer if a certain hash allows this or not. A sequence that contains all the variables in the hash.
