Spring Boot Deployment

build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.2.3.RELEASE'
+       classpath 'org.springframework:springloaded:1.2.1.RELEASE'
    }
}

apply plugin: 'java'
apply plugin: 'spring-boot'

sourceCompatibility = '1.8'
targetCompatibility = '1.8'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.springframework.boot:spring-boot-starter-web'
}

jar.baseName = 'spring-boot-sample'

Add org.springframework:springloaded:1.2.1.RELEASE to the buildscript dependencies. Then run gradle bootRun as usual to enable deployment.

When Using Thymeleaf

If you use Thymeleaf as the template engine, disable caching.

application.properties

spring.thymeleaf.cache=false

For template engines other than Thymeleaf, see this page.

When Using IntelliJ IDEA

Add the following to build.gradle.

build.gradle

apply plugin: 'idea'

idea {
    module {
        inheritOutputDirs = false
        outputDir = file("$buildDir/classes/main/")
    }
}

By default, IntelliJ writes compilation results to a different location from Gradle, which interferes with file monitoring. Change the relevant setting as shown above.
