Springboot中使用Scala开发

新建maven工程,添加pom依賴:

一个简单例子：

package com.demo

import org.springframework.web.bind.annotation.{RequestMapping, RestController}

@RestController
//@RequestMapping(Array("/index"))
class sadsa  {

//  @RequestMapping(Array("", "/"))
  @RequestMapping(Array("/index"))
  def index(): String = {
    "hello SpringBoot"
  }

  @RequestMapping(Array("/index1"))
  def index1(): String = {
    "hello SpringBoot"
  }
}

package com.demo

import org.springframework.boot.SpringApplication
import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter

@SpringBootApplication(scanBasePackages = Array("com.demo"))
class AppConf extends WebMvcConfigurerAdapter {

}
object Runner {
  def main(args: Array[String]): Unit = {
    SpringApplication.run(classOf[AppConf])
  }
}
