Spring Abstractexcelview supports generating Excel files from templates. Specify the path to the template by setting the URL property of the view

Note: 1. The template needs to be placed in the Web-inf directory 2. When specifying a template path, you do not need to add an extension, and spring automatically adds the. xls to the URL property. 3. Set the ApplicationContext of the view before you specify the URL
