I need to send a mail with some HTML content,
but HTML content is in JSP file
I need to set data in JSP file for content, for this, I am using ModalAndView with addObject like this
ModelAndView view = new ModelAndView(PageConstants.wwEmail);
view.addObject("title",title);
view.addObject("content",html);
prepareEmailMessage(message, to, title, view.toString());
Am I doing it in the correct way? or is there any other way to do it?
How can I get HTML with populated data?
As @user404 mentioned in the comment we can use velocity for this, by taking @Syed Shahul answer as a reference, I have achieved my goal of using templates controller, This is my final solution
use these maven dependencies
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity</artifactId>
<version>1.7</version>
</dependency>
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity-tools</artifactId>
<version>2.0</version>
</dependency>
for we need to create a template(.vm) file for this in src/main/resources
then create a VelocityEngine
VelocityEngine velocityEngine = new VelocityEngine();
velocityEngine.setProperty("resource.loader", "class");
velocityEngine.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
velocityEngine.init();
Now we need to generate a template with this velocityEngine
String page = "./ww_email.vm";
Template template = velocityEngine.getTemplate(page);
To pass data to the template we should use VelocityContext
VelocityContext velocityContext = new VelocityContext();
velocityContext.put("title", title);
velocityContext.put("content", html);
Then create a StringWriter to obtain HTML string from template
StringWriter stringWriter = new StringWriter();
Then merge this stringWriter with velocityContext
template.merge(velocityContext, stringWriter);
Finally, you can get HTML string like this
String htmlCodeString = stringWriter.toString()
