Hi Guys,

I have a zkspringboot project and I enable DevelopmentConfig, and then run the application, but my javascirpt file change have to restart server. I need to F5 refresh to browser, how do i do it?

public class DemoApplication {
public static void main(String[] args) throws Exception {

public String mvvmExample() {
    return "mvvm";

public String resourcesExample() {
    return "resources";

public String formExample() {
    return "form";

public String login() {
    return "login";

public String secure(@PathVariable String page) {
    return "secure/" + page;


public void initDevelopmentProperties() throws Exception {
    logger.info("**** ZK-Springboot-Demo: development configuration active ****");

    //disable various caches to avoid server restarts
    Library.setProperty("org.zkoss.zk.ZUML.cache", "false");
    Library.setProperty("org.zkoss.zk.WPD.cache", "false");
    Library.setProperty("org.zkoss.zk.WCS.cache", "false");
    Library.setProperty("org.zkoss.zk.ui.versionInfo.enabled", "true");

    Library.setProperty("org.zkoss.web.classWebResource.cache", "false");
    Library.setProperty("org.zkoss.web.classWebResource.cache.CSS.hours", "-1");
    Library.setProperty("org.zkoss.util.label.cache", "false");
    Library.setProperty("org.zkoss.web.util.re  source.dir", "/json");

    // enable non minified js

    Library.setProperty("org.zkoss.web.classWebResource.cache.etag", "true");
    Library.setProperty("org.zkoss.bind.disableMethodCache", "false");

    // enable for debugging MVVM commands and binding (very verbose)
    Library.setProperty("org.zkoss.bind.DebuggerFactory.enable", "false");

Do you mean you load a javascript manually like:

<script src="~./js/myjs.js"/>
<script src="/js/myjs.js"/>

If you run with maven springboot:run, after you modify a js, you need to trigger a build to update js from the /src to /target/ folder. Because spring boot built-in tomcat doesn't load js directly from your project source.

If this is your case, then even you don't active dev profile, the steps above still work.

For example, in IntelliJ IDEA, after I modify myjs.js, I need to press Cmd+Shift+F9 or click the menuitem below:

It doesn't really compile js but just copy the js to the /target folder.

This solution is very good, he solved my problem. But I will first use the js under the change target for development Because I change a lot and don't want to rebuild all the time
