Spring mvc-Integration (integration)-Generate PDF sample (reprint practice)

The following content is translated from: https://www.tutorialspoint.com/springmvc/springmvc_pdf.htm

Description: The sample is based on spring MVC 4.1.6.

The following example shows how to generate a PDF using the Spring WEB MVC framework. First, let's use the Eclipse IDE and follow these steps to develop a dynamic form-based Web application using the Spring Web framework:

Step	Description
1	Create a project named TestWeb, under a package com.tutorialspoint, as described in the Spring Mvc-hello World Example section.
2	Create a Java class Userpdfview,pdfcontroller under the Com.tutorialspoint package.
3	Download the Itext library itext from the MAVEN repository page. Put it in your classpath.
4	The final step is to create the contents of all the source and configuration files and export the application as described below.

Pdfcontroller.java

Userexcelview.java

Here we have created a pdfcontroller and a userpdfview. The Itext library processes the PDF file format and converts the data into PDF documents.

After you finish creating the source files and profiles, export the application. Right-click the application and use the Export > WAR file option and save your testweb.war file in the Tomcat WebApps folder.

Now start your Tomcat server and make sure you can access other pages from the WebApps folder using a standard browser. Now try the URL http://localhost:8080/TestWeb/pdf, you should see the following results.
