13 title: Fix Hot Reload of Thymeleaf-Templates In spring-boot:run

17 ## The Problem: Hot-Reload Of Thymeleaf-Templates Does Not Work, When The Application Is Run With `spring-boot:run`
19 A lot of people seem to have problems with hot reloading of static HTML-ressources when developing a [Spring-Boot](http://projects.spring.io/spring-boot/#quick-start "Learn more about Spring-Boot") application that uses [Thymeleaf](http://www.thymeleaf.org/ "Learn more about Thymeleaf") as templateing engine with [`spring-boot:run`](http://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-maven-plugin.html "Learn more about the spring-boot-maven-plugin").
20 There are a lot of tips out there, how to fix that problem:
22 - [The official Hot-Swapping-Guide](http://docs.spring.io/spring-boot/docs/current/reference/html/howto-hotswapping.html "Read the official guide") says, that you just have to add `spring.thymeleaf.cache=false` in your application-configuration in `src/main/resources/application.properties`.
23 - [Some say](http://stackoverflow.com/a/26562302/247276 "Read the whole suggestion"), that you have to disable caching by setting `spring.template.cache=false` **and** `spring.thymeleaf.cache=false` and/or run the application in debugging mode.
24 - [Others say](http://stackoverflow.com/a/31641587/247276 "Read the suggestion"), that you have to add a dependency to `org.springframework:springloaded` to the configuration of the `spring-boot-maven-plugin`.
25 - There is even a [bug-report on GitHub](https://github.com/spring-projects/spring-boot/issues/34 "Read the whole bug-report on GitHub"), that says, that you have to run the application from your favored IDE.
27 But none of that fixes worked for me.
28 Some may work, if I would switch my IDE (I am using Netbeans), but I have not tested that, because I am not willing to switch my beloved IDE because of that issue.
30 ## The Solution: Move Your Thymeleaf-Templates Back To `src/main/webapp`
32 Fortunatly, I found a simple solution, to fix the issue without all the above stuff.
33 **You simply have to move your Thymeleaf-Templates back to where they belong (IMHO): `src/main/webapp` and turn of the caching.**
34 It is not necessary to run the application in debugging mode and/or from your IDE, nor is it necessary to add the dependency to `springloaded` or more configuration-switches.
36 To move the templates and disable caching, just add the following to your application configuration in `src/main/application.properties`:
39 spring.thymeleaf.prefix=/thymeleaf/
40 spring.thymeleaf.cache=false
44 Of course, you also have to move your Thymeaf-Templates from `src/main/resources/templates/` to `src/main/webapp/thymeleaf/`.
45 In my opinion, the templates belong there anyway, in order to have them accessible as normal static HTML(5)-files.
46 If they are locked away in the classpath you cannot access them, which foils the approach of Thymeleaf, that you can view your templates in a browser as thy are.
