SpringBoot如何使用Scala进行开发的实现

Scala是一门多范式的编程语言，一种类似Java的编程语言，设计初衷是实现可伸缩的语言并集成面向对象编程。Scala把Erlang风格的基于actor的并发带进了JVM，开发者可以利用Scala的actor模型在JVM上设计具伸缩性的并发应用程序，它会自动获得多核心处理器带来的优势，而不必依照复杂的Java线程模型来编写程序，接下来就介绍一下如何在SpringBoot框架中使用Scala来进行简单的Web开发，对scala不了解的建议先去学习基础哦

一、导入依赖

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent>  <groupId>org.springframework.boot</groupId>  <artifactId>spring-boot-starter-parent</artifactId>  <version>2.2.1.RELEASE</version>  <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.gjing.project</groupId> <artifactId>scala-demo</artifactId> <version>0.0.1-SNAPSHOT</version> <name>scala-demo</name> <description>Demo project for Spring Boot</description> <properties>  <java.version>1.8</java.version> </properties> <dependencies>  <dependency>   <groupId>org.springframework.boot</groupId>   <artifactId>spring-boot-starter-web</artifactId>  </dependency>  <dependency>   <groupId>org.springframework.boot</groupId>   <artifactId>spring-boot-starter-data-jpa</artifactId>  </dependency>  <dependency>   <groupId>mysql</groupId>   <artifactId>mysql-connector-java</artifactId>  </dependency>  <!--加入Scala依赖库-->  <dependency>   <groupId>org.scala-lang</groupId>   <artifactId>scala-library</artifactId>   <version>2.13.1</version>  </dependency>  <dependency>   <groupId>cn.gjing</groupId>   <artifactId>tools-starter-swagger</artifactId>   <version>1.3.0</version>  </dependency>  <dependency>   <groupId>cn.gjing</groupId>   <artifactId>tools-common</artifactId>   <version>1.2.7</version>  </dependency> </dependencies> <build>  <plugins>   <!--加入Scala的编译插件，否则无法进行编译-->   <plugin>    <groupId>org.scala-tools</groupId>    <artifactId>maven-scala-plugin</artifactId>    <version>2.15.2</version>    <executions>     <execution>      <goals>       <goal>compile</goal>       <goal>testCompile</goal>      </goals>     </execution>    </executions>   </plugin>   <plugin>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-maven-plugin</artifactId>   </plugin>  </plugins> </build></project>
