首先,新建一个maven项目,new maven project

  然后打开pom.xml,引入需要的jar包,代码如下:

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.10.RELEASE</version>
  </parent>

 

  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
  </dependency>
  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-devtools</artifactId>
    <scope>runtime</scope>
  </dependency>
  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
  </dependency>
  <dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
  </dependency>

 

  <build>
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-maven-plugin</artifactId>
          <dependencies>
          <!-- spring热部署 -->
            <dependency>
              <groupId>org.springframework</groupId>
              <artifactId>springloaded</artifactId>
              <version>1.2.6.RELEASE</version>
            </dependency>
          </dependencies>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>

 

   其次,新建application.properties配置数据库 

spring.application.name=xx
server.port=8080

spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:8080/test?autoReconnect=true&useUnicode=true&useSSL=false&characterEncoding=utf-8
spring.datasource.username=admin
spring.datasource.password=123456

spring.jpa.database=MYSQL
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

 

  最后,编辑启动类  

  @RestController

  @SpringBootApplication
  public class App
  {
    public static void main( String[] args ){
      SpringApplication.run(App.class, args);
    }

    @RequestMapping("/hello")
    public String hello() {
      return "hello world!";
    }
  }

 

  验证:http://127.0.0.1:8080/hello
