Overview

Documents generation system in docx, odt, pdf, xhtml and pptx formats based on templates.
Supported template formats: .docx, .odt and .pptx

Usage

1. Add repository in pom.xml:

   <repository>
       <id>DocsReporter-mvn-repo</id>
       <url>https://raw.github.com/creepid/DocsReporter/mvn-repo/</url>
       <snapshots>
           <enabled>true</enabled>
           <updatePolicy>always</updatePolicy>
       </snapshots>
   </repository>

2. Add dependency:

   <dependency>
   	<groupId>by.creepid</groupId>
   	<artifactId>docsreporter</artifactId>
   	<version>0.0.1-SNAPSHOT</version>
   </dependency>

3. Then add in context of a Spring application:

   <import resource="classpath*:META-INF/spring/docsreporter-context.xml" />

4. Create report template and map object fields to the model via Mergefields:

5. Define reportTemplate bean instance in Spring context:

   <bean id="reportTemplate" parent="reportTemplateBase">
       <property name="templatePath">
           <value>/pathto/template/DocxProjectWithVelocity.docx</value>
       </property>
       <property name="modelClass">
           <value>by.creepid.docsreporter.model.Project</value>
       </property> 
       <property name="modelName" value="project"/>
   </bean>

   templatePath - path a template (only .docx, .odt and .pptx is supported)
   modelClass - model class (deep hierarchy is possible)
   modelName - context of the model in the template
   

6. In source code generate the document based on the given template:

@Autowire
private ReportTemplate reportTemplate;

Fill the model and generate the document:

Project project = new Project();
...//fill the object

//If we have any dynamic images in our template define ImageExtractObserver instance:
ImageExtractObserver observer = new ImageExtractObserver() {
    public void getImage(byte[] content, String path) {
    //process image extraction event, maybe saving the image in some folder
    }
};

//choosing output document format (.docx, .odt, .pptx, .pdf, .xhtml available)
DocFormat outFormat = DocFormat.PDF;

//receive the resulting document content and save it to file, response wrapper, etc.
OutputStream out = reportTemplate.generateReport(outFormat, project, observer);
