* Handle request to download an Excel = "/downloadExcel", method = RequestMethod.GET) * Handle request to the default = "/", method = RequestMethod.GET) * A Spring controller that allows the users to download an Excel document Coding Spring ControllerCreate a Spring controller class called MainController with the following code: package The hyperlink Download Excel Document points to a relative URL downloadExcel which will be handled by a Spring controller class as described below. Create a folder called jsp inside WEB-INF directory and create a JSP file called home.jsp under WEB-INF\jsp with the following content:
Coding Entry JSP PageWe need to create a JSP page that displays a hyperlink on which the users will click to download the Excel file. Public Book(String title, String author, String isbn, String publishedDate, Creating Java Model ClassWe will generate an Excel document that contains a list of Java books, so create the following model class ( Book.java): package spring-context-support-3.2.3.RELEASE.jarġ.We will end up with the following project structure: The jar files used are: However, you can also download a JExcelApi version of the project in the Attachments section.In Eclipse IDE, create a Dynamic Web Project called SpringMvcExcelViewDemo. And Spring provides an abstract class called AbstractJExcelView which should be extended to generate an Excel document using JExcelApi, similarly to the case of Apache POI.This tutorial will use Apache POI for the sample application. You can download JExcelApi from the following link: JExcelApi DownloadTo work with JExcelApi, you need to add its only jar file: jxl.jar - to your project’s classpath. It supports Excel 2003 file format and older versions. About JExcelApi: JExcelApi is a Java library that is dedicated for reading, writing and modifying Excel spreadsheets. Then using Apache POI’s Excel API to generate the excel document.
