Are you looking for a streamlined way to generate Word documents using templates? Look no further! The poi-tl is an elegant Word template engine based on the Apache POI library, designed to take your text templates and data to create beautifully styled documents effortlessly. In this guide, we’ll explore how to get started, include various tags in your templates, and troubleshoot common issues.

What is POI-TL?

Poi-tl is a Word template engine that allows you to generate new documents based on a Word template and provided data. It excels in retaining the rich styles of the original template while enabling you to set your custom styles too. What makes poi-tl special is its simplicity; it is a logic-less template system based purely on tags, which allows you to focus purely on document design.

Getting Started with POI-TL

1. Maven Dependency

To include poi-tl in your Maven project, add the following dependency to your pom.xml:

<dependency>
    <groupId>com.deepoove</groupId>
    <artifactId>poi-tl</artifactId>
    <version>1.12.2</version>
</dependency>

Note that poi-tl 1.12.x requires POI version 5.2.2 or higher.

2. Quick Start: Your First Template

Here’s a simple example to get you started:

• Create a Word document template, for example template.docx, containing the text placeholder title.
• Use the following Java code snippet to replace the title with the desired text:

XWPFTemplate.compile("template.docx")
    .render(new HashMap<String, Object>() {{
        put("title", "poi-tl template engine");
    }}).writeToFile("out_template.docx");

• Open out_template.docx, and you’ll see the title replaced as desired!

Using Tags in Your Templates

Tags are the core of poi-tl. They allow you to manipulate text, images, and much more. Here’s a breakdown of some key tag types:

Text Tag

The basic tag syntax involves wrapping keys in double curly braces, like {{name}}. When the document renders, this will be replaced with the corresponding value from your data model.

Image Tag

For images, start your tag with an @ symbol, as in @logo. Ensure the data model provides a valid image URL or path string.

Table Tag

To create a table, use the # syntax, for example, #table. The rendered table will consist of rows and columns based on your data.

Looping and Conditions

Sections in your templates can handle conditional and looping logic. For instance, using a section defined by ?section and /section allows you to manage repeated content easily.

Advanced Features

POI-TL supports various advanced operations such as:

• Custom functions (plug-ins) for more dynamic content.
• Markdown conversion for easy text styling.
• Support for nested templates, which allow you to include and render sub-templates seamlessly.

Troubleshooting Common Issues

When working with POI-TL, you might encounter a few hiccups. Here are some troubleshooting tips:

• Ensure all keys in your data model match the tags in your templates.
• If images aren’t rendering, check whether the paths/URLs are correct.
• For dependency issues, verify that your Maven configuration has no errors and that the correct POI version is used.
