本文介绍如何在SpringBoot项目中集成Kotlin语言，并详细展示了build.gradle配置示例及注意事项，如Kotlin类编译后的文件命名规则和启动类配置。

Spring Boot 默认会找一个 main，如果多个 main，需要配启动main。测试代码，写在 test 下面。不要用 main 来写测试。

需要注意的 Kotlin 的类编译之后，class 文件名对应的会在后面加上 Kt

例如，CmsApplication ---> CmsApplicationKt

mainClassName = "com.ak47.cms.cms.CmsApplicationKt"

build.gradle 配置如下：

buildscript {
    ext {
        kotlinVersion = '1.1.60'
        springBootVersion = '2.0.0.BUILD-SNAPSHOT'
    }
    repositories {
        mavenCentral()
        maven { url "https://repo.spring.io/snapshot" }
        maven { url "https://repo.spring.io/milestone" }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:${kotlinVersion}")
        classpath("org.jetbrains.kotlin:kotlin-allopen:${kotlinVersion}")
    }


}

apply plugin: 'kotlin-spring'

apply plugin: 'org.springframework.boot'

group = 'com.ak47.cms'

sourceCompatibility = 1.8
compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}


mainClassName = "com.ak47.cms.cms.CmsApplicationKt"



repositories {
    mavenCentral()
    maven { url "https://repo.spring.io/snapshot" }
