build.gradle 文件没有变化,这里贴一下完整的build.gradle
group 'name.quanke.kotlin' version '1.0-SNAPSHOT' buildscript { ext.kotlin_version = '1.2.10' ext.spring_boot_version = '1.5.4.RELEASE' repositories { mavenCentral() } dependencies { classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" classpath("org.springframework.boot:spring-boot-gradle-plugin:$spring_boot_version") // Kotlin整合SpringBoot的默认无参构造函数,默认把所有的类设置open类插件 classpath("org.jetbrains.kotlin:kotlin-noarg:$kotlin_version") classpath("org.jetbrains.kotlin:kotlin-allopen:$kotlin_version") } } apply plugin: 'kotlin' apply plugin: "kotlin-spring" // See https://kotlinlang.org/docs/reference/compiler-plugins.html#kotlin-spring-compiler-plugin apply plugin: 'org.springframework.boot' jar { baseName = 'chapter11-5-4-service' version = '0.1.0' } repositories { mavenCentral() } dependencies { compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version" compile "org.springframework.boot:spring-boot-starter-web:$spring_boot_version" compile "org.springframework.boot:spring-boot-starter-thymeleaf:$spring_boot_version" // compile "com.fasterxml.jackson.module:jackson-module-kotlin:$kotlin_version" testCompile "org.springframework.boot:spring-boot-starter-test:$spring_boot_version" testCompile "org.jetbrains.kotlin:kotlin-test-junit:$kotlin_version" } compileKotlin { kotlinOptions.jvmTarget = "1.8" } compileTestKotlin { kotlinOptions.jvmTarget = "1.8" }
创建实体类Hello
/** * Created by http://quanke.name on 2018/1/12. */ data class Hello(var id: Long? = 0, var content: String? = "")
创建Controller
import name.quanke.kotlin.chaper11_5_4.entity.Hello import org.springframework.stereotype.Controller import org.springframework.ui.ModelMap import org.springframework.web.bind.annotation.ModelAttribute import org.springframework.web.bind.annotation.PostMapping import org.springframework.web.bind.annotation.RequestMapping /** * Created by http://quanke.name on 2018/1/10. */ @Controller class HelloController { @RequestMapping("/") fun index(map: ModelMap): String { // / 加入一个属性,用来在模板中读取 map.addAttribute("host", "http://quanke.name") map.addAttribute("hello",Hello()) // return模板文件的名称,对应src/main/resources/templates/index.html return "index" } @PostMapping("/hello") fun helloPostSubmit(@ModelAttribute hello: Hello): String { return "result" } }
