Load properties file to beans in spring mvc

Load properties file to beans in spring mvc

There are a few different ways to do it. I do the following. In app context:

<util:properties id="myProps" location="classpath:app.properties" />

Make sure you have the following at the top of your file to include the “util” namespace:

    xmlns:util="http://www.springframework.org/schema/util"
    xsi:schemaLocation= "... http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd"

I usually put my properties files in src/main/resources. As long as they’re on the classpath, you’re good. Then, in your controller, you can annotate your field/method with:

    @Controller
    public class MyController {

        @Value("#{myProps['uploadFolder']}")
        private String uploadFolder

        @Value("#{myProps['downloadFolder']}")
        private String downloadFolder

        @RequestMapping("myPage")
        public String loadPage(ModelMap m) {
            m.addAttribute("uploadFolder", uploadFolder);
            m.addAttribute("downloadFolder", downloadFolder);
            return "myPage";
        }

        public void setUploadFolder(String uploadFolder) {
            this.uploadFolder = uploadFolder;
        }
        public void setDownloadFolder(String downloadFolder) {
            this.downloadFolder = downloadFolder;
        }
    }

Then, in your JSP:

Download folder: ${downloadFolder} Upload folder: ${uploadFolder} HTH. Let me know if you have any questions.
