run scala with java use spring mvc（java项目加入 scala）

1. pom.xml 增加scala lib 和编译配置

    <!--jdk1.8版本加入或者更高版本的 scala-->    <properties>        <scala-version>2.10.4</scala-version>    </properties>    <!-- jdk1.7加入 -->    <properties>        <scala-version>2.9.3-RC2</scala-version>    </properties>

<dependency>    <groupId>org.scala-lang</groupId>    <artifactId>scala-library</artifactId>    <version>${scala-version}</version></dependency><plugins>    <plugin>        <groupId>net.alchim31.maven</groupId>        <artifactId>scala-maven-plugin</artifactId>        <version>3.2.0</version>        <executions>            <execution>                <id>compile-scala</id>                <phase>compile</phase>                <goals>                    <goal>add-source</goal>                    <goal>compile</goal>                </goals>            </execution>            <execution>                <id>test-compile-scala</id>                <phase>test-compile</phase>                <goals>                    <goal>add-source</goal>                    <goal>testCompile</goal>                </goals>            </execution>        </executions>        <configuration>            <scalaVersion>${scala-version}</scalaVersion>        </configuration>    </plugin></plugins>

2. 增加 controller 测试类

import org.springframework.stereotype.Controllerimport org.springframework.web.bind.annotation.{ResponseBody, RequestMethod, RequestMapping}import javax.servlet.http.{HttpServletRequest, HttpServletResponse}import com.nfsq.customer.sync.task.CustomerIncrementSyncTaskimport org.springframework.beans.factory.annotation.Autowiredimport scala.collection.JavaConverters._/** * curl http://127.0.0.1:8080/nfsq_customer_sync/scala/sayHello.json */@Controller@RequestMapping(value = Array("/scala"))class ScalaJobController {  /**   * sacla say hello demo   * @return hello, scala   */  @RequestMapping(value = Array("/sayHello.json"), method = Array(RequestMethod.GET))  @ResponseBody  def sayHello(): String = {    println("hello scala")    "hello, scala"  }  }
