title: spring dev tools does not reload maven resources
body: <p>I have some thymeleaf templates under maven src/main/resources/template path, when I change a controller java file, spring dev tools will trigger a restart, but when I change template files, the livereload does not work. At first, my maven had some problem building the project, it failed to add the files under src/main/resources to target/classes folder, then when I start the spring boot project(using spring tool suite), it showed a error that suggested templates not found. I rebuild the project use "mvn clean package" and restart the spring using spring dash board, it's OK. So I suspect that when I change the template file, it will not impact the target/classes folder, spring dev tools still get template from target/classes instead of detecting the changed file in src/main/resources/. Is there anything I miss to configure for spring dev tools?</p>
